Foreword
Methyl bromide, a potent pest control chemical, was identified as an ODS in 1992. In
1997, countries agreed to the Montreal
Amendment to the Protocol that established
a global schedule to eliminate methyl bromide use and production. Developed countries will phase out MB by 2005 while
developing countries are committed to eliminate it by 2015.
The phase out of this toxic chemical - widely
used in agriculture and other sectors by both
large and small enterprises - presents a special challenge. To replace methyl bromide,
many users around the world must have
access to reliable and useful technical information on non-ozone-depleting alternatives.
They must learn how to select appropriate
options and be able to identify and locate
worldwide suppliers of information, equipment and products. Some will also require
additional technical and/or financial assistance made possible by the Protocol’s
Multilateral Fund, which was specifically created to help developing countries fulfill their
obligations to eliminate ODS use.
UNEP is committed to continue its efforts to
enable developing countries to meet these
challenges with funding from the Multilateral
Fund. Because of the nature of methyl bromide use, many activities to control consumption will be related to knowledge building
and training. Accordingly, UNEP considers the
methyl bromide phase out to be a priority.
UNEP has prepared this Sourcebook to provide critical technical descriptions of the
range of methyl bromide alternatives, data on
cost and efficacy, and an outline of advantages and disadvantages of each option.
Extensive tables, reference lists, and annexes
provide readers with practical information,
including names and addresses of businesses
and individuals who are experts, as well as
vendors of products and services related to
methyl bromide alternatives.
This publication is part of a package of
resources (videos, awareness-raising
brochures, policy and training manuals, etc.)
developed by UNEP to promote the methyl
bromide phase out. Using this sourcebook,
current users of methyl bromide will be able
to carefully and thoroughly assess many available alternatives and decide on the best
option for their situation. Collectively, these
informed decisions can promote a rapid and
successful phase out of methyl bromide,
thereby protecting the earth’s ozone layer,
agricultural production and, importantly, the
economic interests of methyl bromide users.

Foreword
The threats of a depleted ozone layer and the
binding Montreal Protocol have stirred
unprecedented action around the world.
Already, industries and manufacturers around
the world are replacing many ozone depleting substances (ODS) with less damaging substances and practices. However, more remains
to be done. The ozone layer is not yet healed.

Introduction
Methyl Bromide
In many parts of the world, methyl bromide
(MB) helps to control a wide range of pests,
such as soil nematodes and insects in stored
products. It is used mainly in the production
of high value crops like strawberries and
tomatoes, while lesser amounts are used for
grains and traded commodities (Table 1.1).
In 1997, global production of MB was about
71,400 tonnes, with an estimated 68,650
tonnes used for agricultural and related purposes, and the remaining 2,750 tonnes used
as a feedstock for chemical synthesis. Sale
and consumption of MB around the globe
increased at a rate of about 3,700 tonnes per
year between 1984 and 1992.
MB is a versatile pesticide that is effective
against a broad spectrum of pests. It is relatively easy to use and penetrates into soil,
commodities and structures, reaching the
more inaccessible pests. Effective against
most pests at moderate concentrations, MB
provides a relatively rapid treatment.
On the downside, MB can alter the colour
and smell of certain commodities; it produces
bromide ion residues - a cause of concern if
they accumulate in food or water; and it is
highly toxic to humans, requiring special
training and equipment (MBTOC 1994).
MB is also a powerful ozone depletor, and in
1992 it was added to the list of ozonedepleting substances (ODS) controlled by the
Montreal Protocol, an international agreement aimed at protecting the earth’s ozone
layer. In 1997, governments around the world
established a global phase-out schedule for
MB: industrialised countries will phase out
MB by 2005, while developing countries will
phase it out by 2015 (see Table 1.2).

MB used for quarantine and pre-shipment
(QPS) purposes is exempt from Protocol controls. However, Denmark phased out QPS
uses of MB by 1998, and the European Union
has decided to restrict QPS consumption.
Experts estimate that global QPS consumption
has increased (TEAP 1999), and QPS may
become controlled by the Protocol in the
future. A decision under the Protocol in 1999
makes it mandatory for governments to report
data on the amount of MB used for QPS.

Technically feasible MB alternatives have been
identified for more than 90% of MB applications. These include a variety of chemical and
non-chemical measures and carefully selected
combinations of several techniques linked
together in an approach called Integrated
Pest Management or IPM.

Purpose of the Sourcebook
The aim of this Sourcebook is to assist MB
users to phase out their use of the fumigant
by providing:
Information about major technical
options, particularly techniques that are
in commercial use.
Questions for users to consider when
selecting alternatives.
Addresses of experts and product
suppliers.
Sourcebook information is based on the alternatives identified by UNEP’s Methyl Bromide
Technical Options Committee (MBTOC)
(MBTOC 1994, 1998). Specialist information
and technical details were compiled by contacting scientists and extension specialists in
the relevant areas of agricultural technology.
In addition, surveys were conducted in many
countries to identify suppliers of alternative
products and services.
Contents of the Sourcebook
MB is used primarily as a soil fumigant to
control soil-borne pests such as nematodes,
fungi and weeds. It is also used for controlling stored product pests and quarantine
pests in import/export commodities, such as
grain and timber. To a lesser extent it is
applied to buildings and transport, such as
food storage facilities and ships. The major
applications of MB are broken down in Figure
1.1. The Sourcebook divides MB uses into
two major groups:
Soil uses.
Stored products, traded commodities,
structures and transport.
For each of the two groupings, the
Sourcebook covers the following areas:
General guidance for selecting non-ODS
techniques.
Importance of pest identification and
management.
Description of major alternative
techniques.
Efficacy, uses and limitations of each
alternative technique.
Lists of material inputs and suppliers.
Questions to consider when selecting
specific alternatives.

Section 2 provides general guidance for
selecting non-ODS techniques. It outlines
the criteria to be considered when evaluating
alternative options and offers a framework
for organising the wealth of information that
might be considered for selection of MB
alternatives.

Section 3 discusses generally the control of
soil-borne pests. It identifies the main
groups of soil pests, outlines the major strategies for controlling pests and provides steps
for identifying effective alternatives for a
given situation. It also provides examples of
alternatives that are in commercial use in
diverse countries.
Section 4 describes the major alternatives
for soil-borne pests. After a description of
IPM and cultural practices (Section 4.1), it
describes the following techniques in alphabetical order:
Biological controls (Section 4.2).

be used in identifying suitable alternatives. It
also provides examples of alternatives which
are in commercial use in various countries.
Section 6 describes the major alternatives
for stored products, traded commodities
and structures. It starts with a brief description of IPM and preventive measures
(Section 6.1). This section includes examples
of practical activities which prevent pest populations thriving. The following techniques
are described in more detail:
Cold treatments and aeration
(Section 6.2).
Contact insecticides (Section 6.3).
Controlled and modified atmospheres
(Section 6.4).

The recommended approach is to begin with
Section 2, which offers general guidance on
selecting non-ODS techniques.
Questions to ask about the system.
From there you may decide whether you are
interested in controlling pests in soil, stored
products, traded commodities or structures
(see Figure 1.2).
For soil and pre-plant uses of MB,
read Sections 3 and 4 for information
about alternatives.
For stored products, traded
commodities, such as grain, and
structures, read Sections 5 and 6 for
information about alternatives.
For each major alternative technique covered,
the Sourcebook provides information on the
following topics:
The pests it controls.
Current uses.
A brief technical description.
Main equipment and materials required.
Information on efficacy and
performance.
Suitable climates and crops.
Regulatory and market issues.
Cost considerations.
Lists of suppliers of relevant services
and products.
Other useful contacts.
References (provided in Annex 7).
It is recognised that the alternatives often
have to be adapted when applied to new
regions and situations.
When you have read the relevant alternative
techniques section, make a note of the
options that seem to hold promise for your
situation and draw up a list of information
you already have and questions that need to
be answered. You may find it useful to work
through the tables in Annex 4, which contain
detailed steps for evaluating options and
selecting the most appropriate technique for
a given situation.
When you have identified areas for which
you need more information, read the tables
of specialists and suppliers, and review the
references and other information resources
listed in Annex 5. The addresses of companies and specialists are listed alphabetically in
Annex 6.

2 Guidance for Selecting
Non-ODS Techniques
This Sourcebook is a tool for assisting in that
effort and provides detailed information and
references for individual MB users to draw
upon. This Section offers a broad framework
for decision-makers to use in selecting and
organising information relevant to their own
situation. In addition, Annex 4 includes a
step-wise guide for evaluation and selection
of alternative techniques.
Selecting and evaluating alternatives
Growers and others trying to identify suitable
replacement options for MB must gather a
good deal of information - not only about
the technical efficacy and requirements of a
single, promising approach - but also about
other options, costs, secondary impacts and
compatibility with overall goals and operations. There are numerous trade-offs that
must be considered when evaluating the pest
control options.
In general, the factors that decision-makers
must review can be grouped into seven broad
categories:
Organisational.
Technical.
Economic.
Regulatory.
Health and safety.
Market and consumer.
Environmental.
Applicable to most MB users, these factors
are discussed in turn below. It will be difficult
for many MB users to envisage life without
MB. But the experience of phasing out other
ODS which were once seen as essential has
highlighted the necessity of ‘thinking outside
the square’ and the importance of leadership
by innovative individuals and companies.
Organisational considerations
Decision-makers in farms and other MB-using
enterprises need to consider the relationship
between an organisation’s phase-out efforts
and its other activities and priorities.
Competing or conflicting elements must be
recognised and reconciled in a fashion appropriate to the organisation in question.
Important organisational factors are listed
below.
Commitment by decision-makers
Clearly, an enterprise’s phase out of ODS is
greatly facilitated when key managers and
decision-makers throughout the organisation
are fully committed to achieving such a goal.
Programmes to build support within an
organisation will be an important part of an
alternative strategy.
Company policies on pest control,
environmental issues or other matters
Some enterprises may have specific policies
on pest management, including policies that
favour or even require the use of MB fumigation. They may have corporate policies that
Section 2: Guidance for Selecting Non-ODS Techniques
A successful and timely transition away from
ozone-depleting MB rests upon sound decision-making by many thousands of growers
and pest control managers in diverse settings
around the globe. In order to control harmful pests successfully without using this traditional fumigant, each user must carefully
consider and weigh a complex array of factors unique to his or her situation, ultimately
choosing an alternative that fits their particular circumstances.
9
address particular residues, air emissions,
quantity of waste generation, recycling, or
other factors that may be relevant to MB or
certain alternatives. An important step is to
review existing policies and practices, in order
to amend any policies that encourage use of
MB, inhibit the adoption of alternatives, or
otherwise impede the transition away from
MB. It is also desirable to examine relevant
policies of the company’s suppliers and
purchasers.
10
Production methods and schedules
Changing the pest control system for an
operation normally requires changes in other
activities, such as management and daily
practices on the farm or enterprise. Some
alternatives may require higher levels of skill,
and higher or lower labour inputs, for example. Successful adoption of a non-ODS alternative may therefore require adjustments to
management, the organisation of work,
staffing levels, staff selection, and/or training.
Early consideration and planning to address
these changes will ease the transition to new
pest control practices.
Availability of resources
Access to technical and financial resources
may be the factor that has the single greatest
impact on the selection of MB alternatives,
particularly for small and medium-sized enterprises with limited resources. Often a a company has to re-prioritize its existing resources,
and draw on external resources for technical
expertise, advice, information or training. The
Multilateral Fund of the Montreal Protocol
was created to address this problem in developing countries, by providing essential equipment and training for enterprises and farms.
Technical considerations
The selected alternative must be technically
effective in controlling the pest problems in
your local climate and circumstances. MB is
one of many pest control methods, but few
can control the same very wide range of
pests that MB controls. In most cases, MB
must be replaced by a combination of several
techniques which, together, will control the
range of pests likely to be encountered.
Integrated Pest Management (IPM), is based
on pest identification, monitoring, establishment of pest injury levels and a combination
of strategies to prevent and manage pest
problems in an environmentally sound and
cost-effective manner (MBTOC 1998). It
offers a useful overall approach for selecting
and implementing effective, workable alternatives for a wide range of MB uses. Many
specialists around the world recommend this
general approach for dealing with pest problems, and IPM is being used on a wide scale
in some sectors, generally for controlling
pests found on the stems and leaves of crops.
Some IPM programmes have been developed
for soil-borne pests and stored product pests.
The careful tailoring of pest management
practices to a specific situation is fundamental
to the IPM approach. Each application of IPM
involves its own combination of several techniques selected from biological, cultural,
physical, mechanical and chemical control
methods. Formulating and applying a successful IPM programme, therefore, requires
information, analysis, planning, and much
more know-how than does the use of MB.
Sections 3, 4, 5, and 6 give further information about IPM practices and important technical factors to consider in the evaluation of
alternative pest control methods.
Economic considerations
Operating costs and profitability, like access
to capital, are critical factors in the selection
of alternatives. Initial costs associated with an
MB alternative may include capital costs of
equipment, additional costs associated with
handling that new equipment, costs of new
permits or licenses, and costs of training personnel in new systems and methods.
Operating costs may include ongoing costs
for materials and supplies, labour, maintenance or servicing of equipment, or energy
and transportation costs.
What’s more, an assessment of costs alone
does not provide a complete picture.
Alternatives which have higher operating
costs can be as profitable as MB if they give
higher crop yields or raise the market value of
products. Likewise, an alternative that results
in reduced yields can be as profitable as MB if
the costs are sufficiently lower, as found with
solarisation for example. So the profitability
or net revenue needs to be examined.
In future, the price of alternatives will
become more favourable when the inputs
become widely available and the techniques
are optimised. The cost of MB itself will be
much less attractive in future because the
prices of MB will tend to rise as supplies
dwindle. While traditional economic evaluation is very important, it is also necessary to
recognise that an MB reduction programme is
justified on the basis of environmental protection and the need to reduce ‘externalised
costs’ in agriculture.
Finally, the economic analysis could also consider the possibility of accessing funds from
the Montreal Protocol’s Multilateral Fund. The
fund was established to provide financial and
technical assistance for ODS users in developing countries who wish to adopt alternative
techniques.
Funds for MB projects have been made available in the last few years. By the end of 2000
the Multilateral Fund had approved about
100 MB projects, including information materials, workshops and projects to demonstrate
alternatives. In 1999 the Fund decided to give
priority to projects that will phase out MB in
specific sectors, via investment, training and
policy development.
The national ozone protection offices of governments are normally able to provide information about the procedures for applying for
this assistance. Alternatively, the Multilateral
Fund Secretariat website provides information. (See Information Resources in Annex 5.)
Regulatory considerations
Pesticides and fumigants, like MB, normally
have to be registered by the government
authorities responsible for pesticide safety, so
the availability of particular chemicals will vary
from country to country or even within different regions of a country. For example, phosphine, an alternative fumigant for stored
grains, is registered in many countries, while
some other chemical alternatives are registered in only a few countries. Biological controls and soil amendments also require
registration in some countries.
Prospective users of alternative chemicals will
usually find that official approval or registration of a chemical product is accompanied by
diverse safety requirements which limit the
way a product can be applied. The use of
registered pesticides is normally restricted to
specific crops and operations; the application
rates (doses) may be limited; and there are
special conditions on sales, safety equipment,
training and disposal of waste chemicals and
containers. In many instances, restrictions are
set on the levels of pesticide residues that
may remain in foods. Some chemical alternatives, such as sulphuryl fluoride, are not permitted for treating food products at present.
The process of applying for a new pesticide
registration is very expensive, and this task is
normally carried out by companies that wish
to sell the product in countries where they
expect to gain a large market.
To find out whether a product is registered
for use in your country and for your type of
crop or application, it is best to contact the
In evaluating these points, it will be important
to consider the long-term cost package. At
first glance some alternatives may appear
unreasonably costly because they require a
large initial investment in training, equipment, etc. But when costs over the long term
are considered, the same alternatives can
actually be cost-effective.
11
government authority responsible for pesticide safety and registration - often found in
the Ministry of Agriculture or Health. Local
agricultural product suppliers are normally
able to give information on registered products and uses, although their information
may not be up-to-date or completely reliable.
Under international guidelines, registered
products are supposed to carry labels that
inform users on approved uses, application
rates and safety precautions.
12
On the other hand, many non-chemical alternatives, such as steam, substrates and solarisation, are not subject to registration and,
therefore, are accessible immediately to users.
In addition to issues related to the registration
and use of chemical alternatives, there may
be other regulatory issues that affect choices.
Local, state or national regulations may govern emissions, wastes generated or other
aspects of agriculture for example. Exporters
also need to be aware of relevant regulations
in the countries to which they export.
Health and safety considerations
Worker health and safety should be considered in the selection of an MB alternative.
MB itself has high acute toxicity, and in a
number of countries can be used only by
licensed, trained fumigators. Many chemical
alternatives require significant safety precautions as well. In contrast, many non-chemical
alternatives have little or no toxicity, although
a few pose risks of dust or other physical
hazards.
The following are among the health and safety factors that should be examined as part of
the selection process.
Toxicity. The potential for problems of
acute toxicity — resulting from exposure
to significant levels of toxic compounds
over short periods — or chronic toxicity
— resulting from low dose exposure over
longer periods — must be carefully considered for any pest control product. As
with MB, pest control managers should
establish safety management procedures
for avoiding worker exposure and keeping within the safety limits set by health
agencies. It is also necessary to provide
adequate safety training, safety equipment, protective apparel and health
monitoring.
Flammability. Fire and explosion risks
should be evaluated, and preventive
measures instituted if required.
Dust. Workers must be protected from
dusts that can irritate lungs and eyes in
the short-term or lead to lung disease
over the long term.
Suffocation. Certain alternatives, such
as controlled atmospheres, have the
potential to present suffocation hazards
if managed improperly. In considering
these alternatives, safety measures and
training are required to ensure that
workers are not exposed to an environment with insufficient oxygen.
Extreme heat or cold. In adopting an
MB alternative that employs extreme
heat or cold, appropriate measures must
be taken to assure that accidental exposures to extreme temperatures do not
cause injury to workers.
Mechanical hazard. Poorly designed
equipment, lack of safety guards on
moving parts, or worker unfamiliarity
with new equipment can lead to injury.
The need for special training, safety
equipment or other measures to protect
workers must be factored into the selection of MB alternatives.
Problems can be avoided by selecting alternatives free from these problems. Where this is
not possible, safety management is important. This means having a plan and procedures
in place to ensure that safety precautions are
Market and consumer
considerations
Agricultural products have to be acceptable
to purchasers. Visual appearance and commercial grade standards are significant factors, particularly for supermarkets, and
alternatives must provide products that meet
these standards.
Purchasers of agricultural products, from
supermarkets to individual consumers, are
becoming increasingly concerned about pesticide residues and the environmental impacts
of agriculture. Supermarkets in northern
Europe are requiring fruit and vegetable producers to introduce IPM and other production
methods with reduced environmental
impacts. These trends and consumer concerns
will affect the long-term market acceptability
of chemical alternatives, and of MB itself.
Environmental considerations
Like MB, certain alternatives pose risks to
human health or the environment. In the
context of the Montreal Protocol we take a
step forward when we replace an ODS with a
non-ODS. But it also makes sense, from both
marketing and environmental perspectives, to
select alternatives that do not contribute significantly to other environmental problems.
Issues to consider include those listed below.
Ozone depletion and global
warming. Each alternative must be evaluated for its contribution to global
warming and ozone depletion. It would
generally be considered undesirable to
replace an ozone-depleting chemical like
MB with a non-ozone-depleting chemical that has a significant global warming
potential.
Use of non-renewable sources of
energy and materials. Wherever possible, MB should be replaced with alterna-
tives that conserve energy. In some situations it may be feasible to use renewable
sources of energy or waste heat from
local industries. It can also be feasible to
use renewable waste materials as soil
amendments or substrates, for example.
Air pollution. Many pesticides and
other chemicals create fine mists that
pollute the local environment and in
some cases travel thousands of miles to
pollute other regions. Selection of alternatives should seek to avoid or minimise
all forms of air pollution.
Water contamination (surface and
groundwater). Some agricultural practices result in residues and breakdown
products that leach into water, impacting plants and animals that live in the
ponds, rivers and seas. The vulnerability
of water to contamination from everyday
operations and/or accidents should be
considered.
Soil contamination. Some pest control
techniques - notably pesticides - leave
residues and breakdown products in soil
and crop debris, affecting beneficial soil
organisms and non-target plants and
animals. Although active ingredients may
break down quickly, some breakdown
products can persist for long periods.
Food contamination. Some pesticides
can leave undesirable residues and
breakdown products in food, creating
potential problems for consumers, especially young children, or leading to products being rejected by markets.
Increasingly, supermarkets favour pest
control methods that avoid the risk of
food residues.
Solid waste. Waste containers, plastic
and other materials can litter the countryside or fill up large areas of landfill
sites. Where possible, it is advisable to
avoid generating waste, to reduce the
introduced, workers are trained and workplace
practices are carried out safely.
13
14
use of items that create waste, and/or to
set up local recycling schemes.
Identify the environmental impacts
resulting from your operations.
Habitat and biodiversity. Some agricultural practices reduce the diversity of
plants or animals, often by destroying
their habitats. Broad-spectrum treatments like MB, fumigants and steam
sterilisation destroy much of the biodiversity in the soil. Where possible, it is
desirable to use methods which foster
local habitat development, wildlife, and
organisms that benefit crop production.
Consider the entire life cycle of inputs,
including their extraction, transportation,
use and disposal.
The following steps can help to avoid or mitigate potential environmental problems:
Where possible, modify practices to
avoid or reduce negative impacts.
Monitor the efficacy of changes.
Carry out regular reviews, so that the
enterprise’s environmental performance
can be continuously improved.
3 Control of Soil-borne Pests
The five main categories of soil-borne pests
are as follows:
Nematodes. Tiny worm-like creatures
that live in the soil, nematodes vary in
size from microscopic to about 5 millimetres in length. Some species are agricultural pests, while others are actually
advantageous to agriculture. Pest nematodes, generally called plant parasitic
nematodes, feed in or on the roots of
crops. Root knot nematodes for example, cause large swellings in plant roots.
These root galls drain a plant’s energy
resources and limit the uptake of water
and nutrients, thus reducing crop
growth and yields (Strand et al 1998).
Some nematodes transmit harmful viruses or leave open wounds that allow
pathogenic fungi to enter roots.
Fungi. Certain soil-dwelling fungi (such
as species of Fusarium, Verticillium and
Phytophthora) attack plant roots or the
base of stems, causing diseases in the
plants and reducing crop yields.
Bacteria and viruses. A number of soilborne bacteria and viruses are also
harmful (pathogenic) and cause diseases
in crops. As with nematodes and fungi,
the soil contains some beneficial bacteria
that help to protect plant health.
Soil insects. Certain soil-dwelling
insects, such as cutworms and false
wireworms, damage plants by eating
roots or infecting them with fungi or
bacteria. Some of the insects that eat or
damage plant leaves and fruit spend certain stages of their lives in the soil, typically as larvae or pupae.
Weeds. A range of weeds and weed
seeds cause problems by competing with
crops for root space, nutrients, water
and sunlight. These include annual and
perennial broadleaf weeds, grasses and
sedges. A few weeds, such as broomrape, are actually parasitic on crops.
Though it is capable of controlling many
pests (see Table 3.1 through 3.5), MB is often
applied to control just one or two groups of
pests or used as general insurance against the
broad range of soil pest problems. Frequently,
farmers who use MB do not know which
pests are present in soil. Thus some MB is
applied when it is not actually necessary.
Though sometimes portrayed as the perfect
pest control tool, MB does not control all
pests. For example, MB has only limited effect
in controlling the disease caused by
Phomopsis sclerotioides in cucumber
(Gyldenkaerne et al 1997). Likewise, corms
and seeds of weeds such as horseweed, mallow and legumes, and many bacteria are not
effectively controlled by MB (Klein 1996).
There are other disadvantages as well. MB
kills many of the soil organisms that benefit
agricultural production. It is highly toxic;
some forms of application are rather complicated; it may leach into water in some areas;
Section 3: Control of Soli-borne Pests
Soil-borne pests can cause substantial crop
damage and economic losses. This is particularly true in intensive agriculture where crops
are planted in the same place year after year,
creating conditions that foster pest populations in the soil.

MB-based control
One of many pest control methods, MB is
versatile and effective against a broad spectrum of pests, including weeds. (See Tables
3.1 through 3.5.) It is effective at relatively
low temperatures and penetrates soil well,
reaching pests in different areas and soil
depths.
18
Decades of accumulated experience in some
regions of the world have allowed farmers to
make optimal use of MB while avoiding situations in which it is not effective or has severe
local side effects (Katan 1999). As a result,
MB has become highly acceptable and popular with many farmers. Still, around the world
many crops are also produced successfully
without MB (MBTOC 1998).
Overview of alternative pest
control techniques
The techniques identified by the Methyl
Bromide Technical Options Committee
(MBTOC) for controlling soil-borne pests
(MBTOC 1994, 1998) can be divided into the
two broad categories listed below. Each technique is further described in Section 4.
Non-chemical methods
Cultural practices, such as crop rotation,
resistant varieties, grafting, mulching,
cover crops, ploughing, tillage, hygienic
practices or sanitation, and water management.
Biological controls, i.e. beneficial soil
organisms that control or suppress pests.
Soil amendments and compost.
Solarisation.

MBTOC has identified a wide variety of cases
in which alternative techniques are being
used commercially for control of one or more
soil-borne pests (MBTOC 1998). Table 3.8
provides a summary of the main techniques
known to be in widespread commercial use in
some countries. (See Section 4 for additional
detail on each technique.) The countries

Tobacco seedbeds (Table 3.14).
Nurseries (vegetables and fruit)
(Table 3.15).
Perennial crops, e.g., orchard trees,
banana plants (Table 3.16).
Uses without alternatives
MBTOC noted that there is no single crop
that cannot be produced successfully without
MB (MBTOC 1998). However, MBTOC identified a limited number of pests and specific
situations where it is currently difficult to
achieve control without MB, and these
include the following (MBTOC 1994, 1998):
Certain soil-borne viruses that affect a
few specific crop situations.
Deep fumigation of almond groves for
root rot in the USA.
Replant problems in areas where limited
land is available.
Some certified pest-free propagation
materials.
MBTOC has estimated that these difficult
uses account for less than 5% of the MB
Where a narrow range of pests is present,
one technique may give sufficient control.
However, in situations involving a wide spectrum of pests, it is often necessary to replace
MB with a combination of several techniques.
So a combination might comprise, for example, a fumigant or solarisation to control certain nematodes, fungi and weeds, plus a
second technique to control a problematic
nematode species, and a third technique to
manage problem weeds. Identifying suitable
combinations is the key to developing effective MB alternatives.

implemented prior to planting. In addition,
some form of continued protection during
crop production is desirable.
Strategies for controlling pests
Some pest control techniques are primarily
curative and applied after a pest has become
established in the soil. Others aim to prevent
pest populations from building up and thus
avoid the need for curative treatments. After
a plant has become infected, control of many
soil-borne diseases becomes difficult. So, tactics to control diseases must normally be
Examples of curative treatments include fumigants, fungicides, herbicides and steam treatments. Preventive techniques include hygienic
practices, crop rotation (i.e. planting crops in
a planned sequence to disrupt pest life
cycles), use of substrates with inherent pestsuppressive properties, and application of soil
amendments to create an environment antagonistic to specific pests, such as a change in

Tolerable levels of pests.
Sterile conditions: here, the aim of soil
treatment is to kill or eliminate most organisms in the soil in order to create a semi-sterile or sterile medium in which to grow
seedlings, greenhouse crops or very intensive
field crops. MB and other broad-spectrum
treatments fall into this category.
Other techniques in this category include certain combinations of fumigants and pesticides, inert substrates, steam treatments and
solarisation combined with fumigants. A
drawback of creating near-sterile conditions is
that if pathogens enter the system they can
spread rapidly in the absence of natural predators. However, the addition of beneficial soil
organisms to the sterile medium after treatment can help to reduce this problem.
Tolerable levels of pests: in this approach,
key soil pests are reduced to economically
acceptable levels in order to obtain a profitable crop. The aim is not to kill all pests but
to suppress pest activity and reduce pest
numbers to tolerable levels. This approach
relies heavily on the identification and monitoring of pests and is often referred to as an
IPM approach. Methods used in this approach
may include a combination of cultural practices along with mechanical, physical, biological and pest-specific chemical techniques.
In practice, IPM approaches and techniques
vary greatly from one farm or region to the
next. At one end of the spectrum, farmers
may focus heavily on preventive methods,
working, for example, to create soil conditions that suppress pests. Other IPM users
may rely more on curative treatments, such
as target-specific chemicals.
There are many cases in which a broad spectrum of pest control is not required, because
particular pests are absent or below damage
thresholds. When deciding which pest control
techniques to use, therefore, it is always
desirable to first identify the pests present in
soil and then to select the combination of
techniques appropriate for those particular
pests. This identification of pests and selection of targeted control methods is fundamental to the IPM approach.
Crops and crop production
systems
The general techniques available for replacing
MB are broadly similar for most crops, as
shown by the examples given in Tables 3.9
through 3.16. Horticultural crops, however,
can be classified into groups that tend to
have different production problems and
needs:
Vegetables, such as tomatoes, peppers
and courgettes (zucchini).
Soft fruit, such as strawberries.
Orchard trees and vines.
Annual ornamentals.
Perennial ornamentals, such as roses.
Tobacco.
Turf and golf courses.
The spectrum of techniques suitable for each
crop and variety varies, as does the opportunity to intervene and control soil-borne pests.
Different varieties or strains of the same crop
can have very different susceptibilities to
pests. This means that changing from one
variety to another may be part of a transition
away from MB.
The details of each pest control technique
must vary according to the production
system:
Seedbeds, propagation beds and nurseries generally require a high degree of
freedom from pests. This is particularly
true for certified propagation materials.
Alternatives which provide this level of
pest freedom include substrates and efficient steam techniques.
Greenhouses tend to need a high degree
of pest control.
b)
25
Open field crops tend to tolerate slightly
lower levels of pest control, except in
very intensive systems.
The needs of re-planted crops vary
greatly from site to site.
26
Alternatives therefore need to be selected
and adapted to suit the specific crop system,
and to fit the timing of crop production
cycles. For example, if two or more crops are
produced each season, a grower must either
use a technique that fits with the double- or
multi-cropping pattern, or alter the cropping
pattern to accommodate a new approach.
Likewise, for growers who aim to meet particular market windows, it is important to
find techniques which enable the harvest to
be ready when market prices are high.
Identifying suitable alternatives
As noted earlier, MB is effective against a
broad range of pests. In making a transition
away from this fumigant, therefore, many MB
users will find that while a variety of alternative control methods are available, simple
substitution is generally not possible. As
explained above, a mix of alternatives will
often be required.
The selection of appropriate combinations of
alternatives is inherently more complicated
than the traditional use of MB, but the selection process can be simplified and made
manageable by organising information and
following a step-wise decision-making
process.
The key to identifying an alternative for a
specific field or greenhouse is to start by listing the soil-borne pests of the crop or area,
and then list the alternative methods that
could be used to control each pest. Working
from a list of techniques effective for the specific pests, it is possible to identify combinations of techniques that would be effective
for the precise range of pests.
The next stage involves gathering information
about the profitability, advantages and drawbacks of the main combinations. Only with
this sort of information in hand is it possible
to select the most appropriate approach for a
given situation.
For guidance in using this selection approach
along with the information in this
Sourcebook, consider the steps listed below
and review the templates for decision-making
provided in Annex 4.
1.
Identify problem pests at your site.
In addition to current pests, list the pest
problems that existed prior to any use of
MB.
2.
Determine the level of control
required.
3.

down the control methods that
would be technically effective.Table E
in Annex 4 provides a template: list your
key pests in column 1, and list effective
controls in column 2.
4.
Use the lists prepared for each pest
to identify combinations of techniques that would control your full list
of pests. (Annex 4: Table E, column 3).
Once you have identified combinations that
would be technically effective in controlling
all relevant pests, the next stage is to identify
and evaluate the advantages, disadvantages,
profitability and suitability of these combinations for your situation. The following steps
are suggested:
5.
List the technical advantages and
disadvantages of each alternative
combination identified in the previous stage.

acceptability to purchasers, market
requirements and opportunities..

4 Alternative Techniques for
Controlling Soil-borne Pests
Importance of IPM and combined
techniques
As discussed in Section 3, few alternatives
control the wide range of soil pests controlled
by MB, and MB replacement normally
requires a combination of several practices
to achieve a similar level of control. An IPM
approach — which identifies the problem
pests and uses several targeted control
techniques, is therefore important in
replacing MB.
Increasingly recommended as a modern
means of controlling pests, IPM has been
defined in many different ways. MBTOC
describes it as a system ”based on pest monitoring techniques, establishment of pest
injury levels and a combination of strategies
and tactics to prevent or manage pest problems in an environmentally sound and costeffective manner” (MBTOC 1998). Treatment
programmes are site-specific and combine
two or more techniques selected from biological, cultural, physical, mechanical and chemical methods.
This sub-section provides a brief introduction
to the principles of IPM and the major types
of cultural practices that can be utilized for
pest control as part of an IPM approach.
Additional sub-sections discuss the many control techniques that fall under the remaining
categories of biological, physical, mechanical
and chemical methods. As is emphasized
throughout the Sourcebook, virtually all of
these options are best used as part of a wellthought out, comprehensive IPM approach.
Components of IPM
Typical components or steps in an IPM programme may include:
Identification of soil pests and possible
beneficial soil organisms.
A determination of the level of pests
that can be tolerated before treatment is
used. This threshold level is based on the
amount of economic damage that can
be tolerated, the size of the populations
of pests and beneficial organisms, the
time in the growing season, and the life
stage of key organisms and their hosts.
Regular monitoring and record-keeping
on the types and levels of pests and beneficial organisms.
A system of practices to prevent pests
from building up or spreading, such as
cleaning and hygienic practices in greenhouses, and removal of diseased crop
residues.
Application of treatments, as necessary,
to control specific target pests, selecting
treatments that avoid or minimise health
risks to humans, the environment and
beneficial organisms.
Evaluation of the results of practices and
improvements in the system as
necessary.
In IPM programmes, treatments should not
be applied according to a calendar schedule.
Instead, they are applied only when monitoring indicates that the pest will cause
unacceptable damage. Treatments are
restricted to the particular area or spot where
pest problems occur.
Section 4: Alternative Techniques for Controlling Soil-borne Pests
4.1 IPM and cultural
practices
29
IPM approaches are knowledge-based,
because they require growers and their advisers to recognise key pests and beneficials and
to know about effective techniques of prevention and target-specific control. The development and establishment of IPM systems
therefore requires significant effort for local
adaptation and the training of technicians
and growers.
30
IPM systems are used commercially by at least
some growers in many countries. Table 4.1.1
provides examples of crops for which IPM is
used to control soil-borne pests.
Cultural and preventive practices for managing fungal diseases, for example, include the
use of disease-free seeds and resistant varieties, cleaning of tools after use to avoid
spreading pathogens, and removal of dead
and diseased crop debris. Table 4.1.2 provides
a brief overview of the timing and effectiveness of several cultural practices for controlling pests. All of these are discussed in more
detail below. Boxes 4.1.1 through 4.1.3 give
other examples of preventive practices that
assist in the management of nematodes, diseases and weeds.

Cultural practices
In general, the most reliable way to deal with
pest problems is to anticipate and avoid them
(Strand et al 1998), and a wide variety of
standard cultural practices can be used for
this purpose. Selection of fields, sequence of
crops, soil preparation, planting method, timing of planting, choice of variety, fertiliser
application and water management can all be
manipulated to minimise the chances of pest
damage (Strand et al 1998). None of these
techniques on their own can replace MB, but
all can contribute to IPM systems.
Good standards of hygiene and cleanliness
are fundamental to avoiding or reducing the
need for curative treatments such as MB.
Such practices prevent pests from entering or
spreading within the cropping system by
removing sources of pests and preventing
new pathogen inoculum from entering fields
and greenhouses. Many seedling pests, for
example, can be controlled by preventive hygienic practices such as those listed below:
Cleaning tools, equipment and greenhouses thoroughly after use.
Removing infected plant residues from
the previous crop.
Ensuring that contaminated soil or
equipment is not brought into the system or transferred from one greenhouse
or production area to another.
Restricting access to greenhouses,
seedbeds and other areas, to prevent visitors and non-essential personnel from
transferring pathogens on footwear or
clothing.
Using pathogen-free transplants, seeds
and bulbs to avoid introducing new
pathogens into the soil.
Ensuring that irrigation water is free
from pathogens and, if necessary, using
gravel-bed filters or other methods to
clean water before irrigation.

In a number of cases disease-free planting
materials are commercially available; some of
these are certified and regulated. Table 4.1.4
provides a few examples of companies that
supply certified disease-free planting materials. To identify suppliers of certified diseasefree planting materials, contact the relevant
government department (normally the
Ministry or Department of Agriculture) for
information about approved suppliers.
Crop rotation
Rotation involves planting a succession of different crops, each selected for its ability to
withstand or suppress pests that are likely to
have built up during the previous crop’s
growing season. Pathogens that attack only a
few crop species can be controlled by rotation, but rotation is not suitable for
pathogens that remain in soil for a long time
or affect a wide range of crops. Rotation is an
ancient and reliable method, but rotations

Use disease-free seeds or planting material.
Avoid old or poor quality seeds.
Where available, use resistant varieties or grafted plants with resistant rootstock.
Select planting sites so that susceptible crops are not planted in heavily infested fields.
Use transplants where feasible, because damping-off fungi rarely attack established seedlings.
Clean tools and equipment after use to avoid spreading pathogenic organisms.
Clean footware before entering greenhouses and seedbed areas.
Remove diseased crop residues.
Rotate to non-host crops where feasible. (Various guides are available for choosing rotations
of vegetables according to disease problems, e.g. Peet 1995.)
Be aware of the impact of organic matter. Soils high in organic matter may have higher populations of damping-off fungi, but they can also increase the activity of beneficial microorganisms that suppress pathogenic fungi.
Manage water and drainage to keep soil around roots from becoming waterlogged, because
root rots and damping-off occur in areas with poor drainage.
Avoid practices that encourage damping-off, including deep planting, planting into cold, wet
or poorly prepared soil and inadequate soil nutrition.
Balance watering and fertiliser applications carefully, because excess water and nitrogen
encourage certain pathogens.
Avoid under-nutrition, because stressed plants that are low in potassium and calcium are
more vulnerable to diseases.
Avoid too much fertiliser, because the salts may damage roots, opening the way for secondary infections by opportunistic pathogens.
Control virus-transmitting insects very early in the season, using oils, soaps and baits, for
example.
Remove and destroy weeds that transmit viruses, such as solanaceous weeds.

Determine the critical weed-free period, that is, the length of time during which the crop
should be practically weed-free to avoid reductions in yield or quality.
Make sure that crop seed and mulches do not contain weed seeds.
Mow around the field borders to remove sources of weed seeds.
Prevent weeds from producing seeds by removing them before seeds develop, for example.
Band fertilisers five to ten centimetres from the plants, rather than broadcasting.
Rotate crops where feasible.
Compost any manure before use to reduce weed seeds.

Resistant varieties and grafting
Some varieties are resistant to specific pests,
and resistant varieties are widely used in
Spain, Portugal, Greece, Morocco, France,
Israel, Italy and Colombia to help substitute
for soil fumigation (MBTOC 1998). The range
of resistant varieties is limited to specific
pests. In some varieties the resistance can
break down under certain conditions, such as
high soil temperatures or saline water. Target
pests must be identified before the appropriate resistant or partly resistant cultivar can be
selected. Table 4.1.4 lists examples of companies that supply resistant varieties.
Grafting plants onto resistant rootstock has
traditionally been used for fruit trees, citrus
trees and grape vines, but is now being used
for annual crops such as tomatoes, cucumber
and melon. This practice is increasingly popular in countries such as Morocco, Tunisia,
Lebanon, Egypt, Jordan and Cyprus. The
watermelon crop in Almería (Spain), for
example, is raised from grafted plants, eliminating use of MB (Tello 1998). In some
regions of China, cucumber and watermelon
are grafted onto Cucurbita moschata rootstock because it is resistant to Fusarium oxysporium f.sp. cucumerinum (Tang 1999).
Grafting can be done mechanically by nurseries or specialised farms. It can also be done
by small farmers using simple equipment
such as clean, sharp blades, sticky tape and
small tubes or clips to stabilise the joined
stems (Lung 1999). Table 4.1.4 lists examples
of companies who supply grafted plants and
rootstock for grafting. See Annex 6 for an
alphabetical listing of suppliers, specialists
and experts. See also Annex 5 and Annex 7
for additional information resources.
Mulches and cover crops
Mulches are materials that cover the soil,
helping to suppress weeds and certain other
pests. For example, opaque black plastic or a
thick layer of waste material can exclude or
reduce the light that triggers weed seed germination. The use of cover crops to smother
weeds is a long-established and widely used
cultural practice that can also contribute to
the management of diseases and nematodes
(Peet 1995).
Cover crops must be correctly selected and
managed to compete with weeds for
resources, and preferably to possess chemical
or allelopathic properties that reduce weed
growth. Certain grasses have been used to
suppress Sclerotinia sclerotiorum, for example
(Ferraz et al 1996). Living mulches composed
of miniature brassicas or clovers grown with
the main crop can also suppress weeds and
reduce insect pests without reducing yields in
some cropping systems (Thurston et al 1994).
Nutrient management
Manipulation of plant nutrition and fertilisation can reduce or suppress some soil-borne
pathogens and nematodes by stimulating
antagonistic microorganisms, increasing
resistance of host plants, and/or other mechanisms (Cook and Baker 1983).
Time of planting
Selection of a planting time that coincides
with environmental conditions unfavourable
to pest activity can reduce problems with
some diseases (Heald 1987, Trivedi and Barker
1986). For example, relatively high temperatures do not favour Verticillium spp., while relatively low temperatures do not favour
Fusarium spp. Selecting the appropriate planting time can also help to control root-knot
nematodes in some regions (Bello 1998).
Trap crops
Some plants kill or suppress specific pests.
Tagetes, a type of marigold, for example, suppresses specific nematode species, and can be
have traditionally included lower value crops
that do not suit MB users. New rotations
involving only high-value crops are now being
developed. For example, a three-year rotation
including melon, hot pepper, peas, cucumber,
tomato and squash is used with metam sodium as part of an IPM system in Morocco
(Besri 1997).

Water management
Excessive water creates conditions that favour
infection by some soil-borne fungi, such as
Phytophthora root rot and damping-off diseases in tomato or root and crown diseases in
strawberry (Strand 1994, Strand et al 1998).
Too little water, on the other hand, stresses
plants and may also make them more vulnerable to attack. Proper water management
contributes to disease control in vegetables in
southeastern Spain and USA (MBTOC 1998).
In areas where excess water is available at
appropriate times of the year, temporary
flooding or flooding alternated with dry soil
can be used to suppress insects or weeds.

Generally safe for non-target species and
not toxic to humans.
Inducing systemic resistance in crops,
i.e., improving the plants’ own defense
systems, enabling them to resist pest
attacks more effectively.
Improve soil biodiversity.
Stimulating crop growth.
Advantages

around crop roots and protecting them
against infection.
Do not produce undesirable residues in
food.
Can lead to antagonistic activity in the
soil for long periods.
Disadvantages
Target specific pests, so must be combined with other techniques.
Not compatible with conventional pesticides, since pesticides kill or inactivate
the organisms.
Must be applied regularly in order to
establish populations of biological organisms in the soil.
Normally require a certain range of pH,
temperature and moisture to be active.
Often need to be registered as pesticide
products, which may initially delay their
availability.
Technical description
Biological control involves the use of living
organisms, such as fungi, bacteria or beneficial nematodes, to control or inhibit pest populations. Biological control agents can act
against pests in diverse ways, including those
listed below:
Eating or feeding on pests.
Parasitising or living in pests.
Repelling pests.
Competing with pests for space and
nutrients.
Establishing a kind of ‘biological shield’
Biological controls are normally highly specific, which means that each organism or agent
acts against a narrow range of pests —
typically between one and a dozen pest
species (Table 4.2.2). Generally, biological
controls cannot, of themselves, replace MB.
Rather they must be used as part of an IPM
system that includes other practices, such as
resistant cultivars, soil amendments, solarisation or alternative pesticide products.
Biological controls are effective only when
present in sufficient numbers in the root
zone, so success depends on selecting the
appropriate method of delivery, establishing
an environment in which the organisms can
thrive, or re-applying the organisms at regular
intervals. They are often most effective when
applied as seed dressings and root dips or
applied to the soil regularly via irrigation
pipes.
Biological control products are made commercially or, in some cases, on-farm.
Commercially produced biological controls
can be categorized as follows:
Fungi or bacteria
Fungi or bacteria are primarily soil-dwelling
organisms that prey upon or out-compete
some of the pathogenic fungi that attack
plants. Examples of commercial products
include the following:
Beauveria spp. – a fungus (commercial
products in Colombia and Switzerland).
Fusarium oxysporum (nonpathogenic) – a fungus (commercial
product in France, Hungary, Italy).

Paecilomyces lilacinus – a fungus (commerical products in Colombia).
Pseudomonas spp. – beneficial bacteria
(commercial products in China,
Germany, USA).
Trichoderma spp. – various species of
fungi (commercial products in China,
UK, USA, Zimbabwe and many other
countries).
Steinernema spp. – beneficial nematode
(commercial products in USA).
Biological controls come in a wide variety of
formulations such as wettable powders, granules, pellets and suspensions. They can be
applied as top dressings, sprays, drenches,
seed coatings or root-dips prior to planting.
They can also be applied via sprinklers, drip
lines and injection equipment, or can be
mixed with substrates (potting mixes or
growth media) prior to filling nursery trays
or bags.
Nematodes
Nematodes are soil-dwelling animals that
look like microscopic worms. Some predatory
nematodes prey upon root-knot nematodes
while other types of nematodes act as parasites and destroy the larve and pupae of
insects (Table 4.2.3). Examples of commercial
products include:
Heterorhabditis bacteriophora – beneficial nematode (commercial products in
USA).
Mononchus sp. – beneficial nematode
(commercial product in USA).
Phasmarhabditis hermaphrodita – beneficial nematode (commercial product in UK).
Seed coatings and root dips are effective
methods of application, because they allow
the beneficial organisms to become established in the root zone from the earliest
stages. Depending on the pest pressure and
situation, it may be necessary to create a soil
environment that fosters the biological control agent and provides appropriate nutrients
for it, or it may be necessary to re-inoculate
the soil with the organisms at regular intervals. An effective way to ensure that organisms remain present during the entire
growing season is to apply them regularly
through the irrigation pipes (using special
valves that will not become blocked).
Gliocladium virens – a fungus (commercial products in USA).

Users need to be knowledgeable about
appropriate conditions. As living organisms,
most biological control agents are active
within a certain range of temperatures and
soil conditions. For example, Trichoderma
needs a soil temperature of at least 10°C and
a soil pH that is neutral to slightly acidic. The
beneficial nematode Steinernema needs
slightly moist soil and temperatures of 4.5 to
32°C, with optimum temperatures of 15.5
to 21°C.
Normally biocontrols will be killed or deactivated by pesticides. A notable exception,
however, is the bacteria Pseudomonas, which
has tolerance against some fungicides. In
general biological controls are best suited for
use with non-chemical techniques such as
grafting, substrates or solarisation.

Current uses
Biological controls are used commercially in a
number of countries, normally as one part of
a comprehensive IPM or non-chemical system. Table 4.2.1 provides examples of biological control agents in commercial use.
Variations under development
Additional species with pest control effects
are being identified. Studies of the microbial
communities of roots in undisturbed ecosystems where major diseases rarely occur can
assist in determining the key microorganisms
that play a role in plant health (Linderman
1998). Improved formulations and delivery
systems are also under development.
Material inputs
Biological control organisms —
purchased or made on-farm.
Mechanism for conveying or incorporating biological controls into the soil.
Equipment, such as irrigation pipes,
sprayers, or fertiliser injectors, is often
already available on farms.
Factors required for use
Know-how and training. Users must first
identify biological controls that will be
effective in the region. They must also
be knowledgeable about pest and
predator life cycles, appropriate timing
of treatments, temperature, irrigation,
soil types, application methods and optimal storage of products.
In some countries official registration by
pesticide authorities is required before
products can be marketed.
Users must be able to control or manipulate soil temperature, acidity and/or
moisture to be within the appropriate
range for activation.
Biological controls are not compatible
with some pesticide treatments. Steam
treatments and fumigants also kill biocontrols, unless the biological controls
are applied after the other treatment.
Pests controlled
Biological controls can suppress or control
specific species of nematodes, fungi and soildwelling stages of insect pests. They are normally highly specific and cannot replace MB
on their own, so they are best used as one
part of a combined system.
Tables 4.2.4 through 4.2.6 provide examples
of biological agents that can be used for control of nematodes, fungi, and bacteria and
insects, respectively. Certain biological control
agents can be applied together to increase
the range of pests controlled. They can be
used curatively to reduce an existing infestation and/or as maintenance treatments to

provide ongoing protection from pests.
Predatory nematodes can act swiftly, while
other nematodes have a slow effect, so efficacy can vary according to the type of biological control agent, the type of pest, the
original level of infestation and soil conditions
such as temperature.
Yields and performance
Biological controls need to be combined with
other techniques in order to give efficacy and
yields equal to MB fumigation.
Other factors affecting use
Suitable crops and uses
Biological control products have been
approved in some countries for many horticultural crops, nurseries, trees, turf, mushrooms and other crops. They can be used in
greenhouses, seedbeds, nurseries and open
fields. However, the appropriate applications
vary greatly from one product to the next, so
it is important to check local suitability before
purchasing products. They are suitable for
single, double- and multi-cropping systems.
Suitable climate and soil types
Biological controls need to be selected to suit
the temperature range of the area where
they will be used, because each organism has
an optimum range for biological activity. They
can be used in many soil types, although this
may vary with the specific organism. The soil
pH (acidity or alkalinity) can enhance or limit
some biological controls.
Toxicity and health risks
Approved biological controls are generally
safe for humans because they act against
selected soil organisms. However, it is desirable to avoid breathing dusts or spray formulations, because dust in general is a health
hazard and there is a possibility of allergic or
intolerant reactions to foreign protein.
Safety precautions for users
Approved biological controls are generally
considered safe to users and rural communities, because their action is confined to specific soil pests. Special safety training is not
required for registered products. Protective
equipment should be used with formulations
that generate dust or spray particles.
Residues in food and environment
Biological controls make a positive contribution to the soil environment. Approved
organisms do not leave undesirable residues
in food or the environment.
Registration and regulatory
restrictions
Regulatory approval is required in some countries. In the past, some biological controls
(e.g. cane toads in Australia) have been
released without adequate scrutiny, leading
to problems for indigenous species. For some
years there has existed an international code
of practice on the introduction of non-native
organisms into new regions, and this is
applied in many cases. Quality assurance
schemes are necessary for manufacturers
who produce biological controls.
Cost considerations
Approved biological controls are not toxic to
crops. Some actively promote crop growth.
Impact on beneficial organisms
Use of biological controls increases the population of beneficial organisms and generally
increases biodiversity and antagonistic activity
in the soil. Some predatory nematodes, however, may prey on certain beneficial organisms as well as pests.
Material costs of biological controls are
lower than MB.
Labour costs for applying biological controls would be similar to the cost of a
conventional pesticide spray or top
dressing; application via irrigation systems entails negligible labour.
Since biological controls need to be used
as part of a combined system, it is necessary to calculate the cost of the other
components before comparing to MB.
Ozone depletion
Biological controls are not listed as ODS.
Global warming and energy
consumption
Manufacturing of biological controls uses less
energy than does production of MB. Tractor
application requires use of fuel, similar to
mechanised MB application; application via
irrigation water does not.
Other environmental considerations
Product packaging produces small amounts
of solid waste.
Acceptability to markets and consumers
Biological controls are very acceptable to
supermarkets, purchasing companies and
consumers because they enhance biological
diversity and are seen to be a positive
replacement for pesticides.
Questions to ask when selecting the
system
Which soil pests need to be controlled?
What degree of pest control is needed?
Which biological controls will control
these pests? To what degree?
What practices are required to ensure
that the biological control agent reaches
the roots, thrives and is effective in the
soil?
What is the most effective form in which
to apply the organism?
What amount needs to be applied and
how often?
What measures need to be taken to control other key pests (IPM system)?
Phytotoxicity

What are the costs and profitability of
this system compared to other options?

Advantages
Fumigants generally control a relatively
wide range of pests.
Fumigants and pesticides can be as
effective as MB, if several techniques are
combined.
Some products are widely used, so
materials and information are
accessible.
Application methods, equipment and
pest control approaches are more akin to
MB fumigation than are other types of
alternatives.
Disadvantages
Most products are toxic to humans and
non-target organisms.
Many leave residues or breakdown products in water, air, soil, wildlife and/or
crops, thus leading to concerns about
environmental polution.
Correct application techniques vary from
product to product and are very important for efficacy.
Products are not registered in some
countries, restricting availability.
Many require waiting periods longer
than MB.
Use requires safety equipment and compliance with safety restrictions.
Fumigants are volatile chemicals that exist as
gases or are converted into gases under typical field conditions. In contrast to other
chemical products, which are normally active
in solid or liquid form, fumigants move
through the soil principally as a gas or
vapour.
Both types of products control pests because
they are highly toxic to pests or because they
generate toxic substances. To be effective
they have to be present in sufficient concentrations to kill the target pests. Alternative
fumigants and other chemical products do
not kill the same wide range of pests as MB.
Therefore, they are best used with other
treatments or practices and/or employed
selectively within an IPM system.
Depending on the formulation, chemicals can
be injected, sprayed on the soil surface,
mechanically incorporated or distributed via
irrigation pipes. Products to control nematodes are normally applied before planting, in
the case of fumigants, or at the time of
planting, in the case of pesticides. To prevent
re-contamination of soil, hygienic practices,
such as cleaning equipment before moving it
and avoiding infected seeds and contaminated irrigation water, should be followed.
Fumigants are often supplied in liquid form
and require a minimum temperature of about
5 to 7°C. They include two groups:
True fumigants, such as 1,3-dichloropropene and chloropicrin, which are
volatile and able to move through the
soil airspaces as gases or vapours.
“Non-true” fumigants, such as metam
sodium and dazomet, which act more
like contact pesticides.
For non-true fumigants, water is very important in moving the chemical through the soil
to target pests. So in general soil should be
quite moist when applying non-true fumigants and rather dry when applying true
fumigants (Hafez 1999). True fumigants are
often described as better nematicides than
non-true fumigants, but non-true fumigants
can be effective nematicides if applied in
ways that ensure they reach target pests.
Most are not effective against weed seeds
4.3 Fumigants and
other chemical
products
51
but can control weeds if they are germinated
by irrigation prior to the fumigation.
Table 4.3.1 compares the characteristics of
some major fumigants. Table 4.3.2 shows the
categories of pests controlled by fumigants
and pesticides. Fumigants registered in some
or many countries include the following:
52
Chloropicrin or trichloronitromethane is
a liquid, which is injected into the soil,
typically to a depth of 15 to 28 cm. The
soil is subsequently covered with plastic
or sealed. It diffuses well through soil
but needs to be combined with other
techniques to fully control weeds and
nematodes. The acute toxicity and noxious smell of chloropicrin may limit its
use in some areas.
Dazomet’s primary ingredient is tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2thione. It is registered or approved for
use in many countries and formulated as
a solid material in granular form, making
it easier to handle than other fumigants.
It is generally incorporated into the soil
by roto-tilling. To aid distribution of
dazomet, soil needs to be prepared prior
to application, finely cultivated, above

10°C and moist; soil covering is not necessary. Dazomet generates a fumigant
gas called methyl isothiocyanate (MITC)
and other fumigant breakdown products, such as carbon bisulphide and
formaldehyde (MBTOC 1994). The soil
persistence of these is influenced by
temperature and moisture. If application
conditions are sub-optimal, such as cool
and wet, a longer waiting period before
planting crops may be necessary to avoid
phytotoxicity (toxicity to crops).
Metam sodium consists of sodium
methyl-dithiocarbamate, which generates MITC in the soil. Formulated as a
liquid, it may be applied to the soil by
injection or drip irrigation or sprayed
onto the soil surface prior to tilling. The
soil must be prepared and free from
clods before application. Metam sodium
does not distribute easily in the soil and
can give variable pest control depending
on soil temperature, texture, organic
matter, moisture, pH and distribution.
Water is essential for good movement in
the soil. With improved application techniques and better surface sealing,
metam sodium can give results equal to
MB fumigation (MBTOC 1998). It can be
combined with solarisation or other pesticides for greater efficacy. Metam sodium is registered in many countries and
has been used for more than four
decades in California USA for the production of tomato, strawberry and
pepper crops.
1,3-dichloropropene (1,3-D) is a halogenated hydrocarbon. It is formulated as
a liquid and injected into soil, followed
by sealing of the soil surface with a
roller, water or plastic to trap the gas.
Newer formulations can be applied via
drip irrigation pipes under impermeable
plastic sheets. The soil may be moist
before application and the temperature
should be at least 10°C. The toxicological profile of 1,3-D may limit its use in
some areas.
Methyl isothiocyanate (MITC) is a liquid that is injected into soil. It is mostly
used in combination with 1,3-D to
enhance nematode control. A waiting
period of up to eight weeks may be

Mixtures of soil fumigants provide a
spectrum of pest control similar to MB.
Mixtures of 1,3-D and chloropicrin, for
example, are registered in some regions.
Soil may be pre-irrigated to stimulate
nematode development to active forms
and then allowed to become fairly dry
by the time the fumigant product is
applied. The liquid is often applied
mechanically by soil injection to a depth
of about 46 cm, with the soil surface
sealed. The soil should usually be left
undisturbed for at least 7 days and
planting should be delayed for 21 days
or more if conditions have been cold
and wet.
The efficacy of fumigants depends greatly on
the preparation and application method,
because many factors influence efficacy,
including the pest species, degree of infestation, type of fumigant, soil preparation, soil
type, pH, organic matter, presence of crop
residues, soil depth, soil temperature, application rate and application method. Soil pests
should be identified before selecting the
appropriate fumigant and co-treatments.
Good soil preparation (e.g., producing a fine
tilth) is normally important for helping fumigants to diffuse through the soil and reach
the pests. Finer soil textures with a high percentage of silt and clay have smaller pore
sizes, and this characteristic tends to block
the movement of fumigants. So these soils
generally require higher application rates.
Debris from the previous crop may harbour
pests and should be chopped up and incorporated into the top 10 cm of soil and
allowed to decompose before fumigation.
Fumigants are generally most effective when
the soil temperature is 21 to 27°C at a depth
of 20 cm, although fumigation can be carried
out when soil temperatures are 7 to 30°C at
20 cm depth (Hafez 1999).
All fumigants and pesticides are normally
required to carry instructions for application
methods and safety precautions, and these
instructions should be followed in all cases.
In general, deep placement of a fumigant in
the soil (e.g. injecting it to 38 to 46 cm
depth) gives better pest control than with
shallow placement (e.g. 15 to 23 cm depth).
A number of factors influence the rate at
which fumigants become active. For example,
clay soils tend to slow the conversion of 1,3D with chloropicrin to the gas phase, while
they increase the rate at which metam sodium is converted to MITC. A higher soil pH
and available copper, iron or manganese in
the soil can speed up the conversion of
metam sodium to MITC. Raised soil temperatures also increase the rate of conversion of
metam sodium to MITC and the conversion
of 1,3-D + chloropicrin to the gas phase
(Hafez 1999).
Pesticide products
Pesticide products are chemicals with toxic
properties. They are available as liquids, granules or powders. Their modes of action vary;
for example, some kill by contact and others
by systemic action. They tend to be effective
against specific sub-groups or groups of
pests. Some control a wide range of species,
while others control a very limited range, so
soil pests must be identified before appropriate products can be selected. The names of
the main groups of pesticides indicate the
types of pests that they control:
Nematicides control nematodes.
Current uses
Both fumigants and non-fumigant pesticides
are used commercially. The fumigant metam
sodium is used in many countries, including
Israel, Italy, Morocco, Spain, southern France
and USA, while dazomet is used in regions
such as Argentina, Australia, Europe and
Japan (MBTOC 1998). Mixtures of 1,3dichloropropene with methylisothiocyanate
and 1,3-dichloropropene with chloropicrin
have been used for many years on a variety
of crops in North America (MBTOC 1994).
Table 4.3.3 provides more examples of the
commercial use of fumigants.
Some potential fumigants are being examined in trials, including:
Methyl iodide.
Ozone.
Sodium tetrathiocarbonate.
Anhydrous ammonia.
Furfuraldehyde.
Material inputs
Fumigant or pesticide products.
Equipment for injecting, spreading or
distributing the products into soil.
Fungicides control fungi.
Equipment to seal the soil surface or
plastic sheets to cover the soil.
Herbicides control weeds.
Safety equipment.
Insecticides control insects.
These groups are not discussed in detail,
because the available pesticide products vary
greatly from country to country, depending
on the approved formulations. Relevant information can be obtained from agricultural
suppliers and the government departments
responsible for pesticide registration.
Fumigants and pesticides should only be
used where government registration of
the chemical has been given for the specific crop/situation in question. This will
vary markedly from one country to the
next, and even from state to state in
some countries. To determine the registration status and permitted uses of
products, contact the national or state
Likewise, applying the fumigant to the entire
field area is more effective than placing it
only along the rows where crops will be
planted.

Ministry of Agriculture or Health.
Know-how is important for proper application of the products, since efficacy
depends greatly on good distribution in
the soil. Most fumigants need a particular soil temperature range, soil texture
and moisture level for even distribution.
Fumigants and pesticides require knowledge of safety measures.
Pests controlled
Fumigants and other pesticides vary in the
range and efficacy with which they kill pests.
In general, they do not kill as wide a range of
pests as MB, so they are best used with other
treatments as part of an IPM system. Table
4.3.2 indicates the main pest groups controlled by available chemicals:
Chloropicrin is highly effective for the
control of soil-borne fungi, about 20
times more effective than MB in this
respect (Desmarchelier 1998). It controls
germinated weeds and some arthropods.
It is a weak nematicide and does not kill
dormant or non-germinating weed seeds
(MBTOC 1998).
Dazomet provides control of soilborne fungi, some weeds and certain
nematodes.
1,3-dichloropropene provides effective
control of nematodes but little control of
diseases and weeds (Johnson and
Mixtures of 1,3-dichlorpropene and
chloropicrin are effective in controlling
nematodes, deep-rooted perennial
weeds and soil-borne insects.
MITC is highly effective for controlling a
wide range of soil-borne fungi, arthropods, some weeds and limited species of
nematode species (MBTOC 1998).
Metam sodium provides effective control of fungal pathogens, arthropods,
certain weeds and a limited number of
nematode species (MBTOC 1998).
Nematicides control nematodes or specific types of nematodes, and some soil
insects.
Fungicides control specific fungi or
groups of fungi.
Herbicides can control a narrow or
wide range of weeds, depending on the
specific product.
As mentioned previously, efficacy can be
affected greatly by soil type, soil preparation
and application methods. The efficacy of
fumigants against nematodes and weeds
can be improved by pre-irrigation to encourage nematode development and weed
germination.
Additional information on the types of pests
that specific products will control can be
obtained from approved product labels and
extension authorities. Regional information is
also available on extension websites, such as
the University of California Pest Managment
Guidelines (see list of websites included in
Annex 7).
Yields can be lower than, equal to, or higher
than those achieved using MB, depending on
the chemical and application method. Table
4.3.4 provides some examples of yields.
Fumigants and pesticides can be used for the
horticultural crops for which they are registered in a country or state. It is feasible to use
them in open fields, greenhouses, tunnels,
seedbeds, nurseries. However, the permitted
applications will vary greatly from country to
country. They can be used in single and double-cropping systems.
Suitable climates and soil types
Most fumigants work within certain temperature ranges and require a minimum of about
5 - 7°C. Some chemicals are not effective if
the climate or soil is too wet or too dry.
Efficacy also varies with the soil type, particle
size, pH and percentage of organic matter.
Lighter soils generally require lower fumigant
application rates, while heavier soils generally
require higher application rates. Additional
information on appropriate conditions can be
obtained from product labels or extension
agencies.
Fumigants and pesticides are designed to be
toxic to living organisms. The main hazard to
field workers is during mixing and handling,
but they can also drift to neighbouring farms
and communities, posing risks to human
health, crops and wildlife. Fumigants and
some pesticides are acutely toxic, i.e. exposure to sufficient concentrations can rapidly
produce symptoms of poisoning or ill health.
Others may be associated with chronic toxicity, i.e. symptoms of ill health may develop a
long time after exposure has occurred. Annex
3 gives data sheets for the major fumigants.
Safety equipment and training is necessary
for users and for the protection of local communities. All safety instructions given by
product labels and health authorities must be
followed.
Feldmesser 1987, Rodríguez-Kábana et
al 1977).
57
Many fumigants and pesticides leave undesirable residues and metabolites in air, soil,
crops and food. Some residues can move into
surface or groundwater, and some persist in
the environment for a long time and may
accumulate in the tissues of living organisms.
Phytotoxicity
58
Fumigants often leave phytotoxic residues,
but this problem is normally overcome with a
waiting period of about two to three weeks
or longer before planting.
Fumigants generally kill many beneficial
organisms in the soil, while pesticides kill certain groups of organisms. For example, fungicides often kill or suppress beneficial fungi.
Ozone depletion
Commercially available fumigants such as
metam sodium and 1,3-D are not ODS.
Methyl iodide has a low ODP.
consumption
As with MB, energy is used in the production,
transportation, use and disposal of fumigants
and pesticides and related equipment, such
as application machinery and plastic sheets.
Some fumigants and pesticides are manufactured from non-renewable resources such as
oil. After use, chemical residues do not disappear but are converted into metabolites and
other residues, some of which are harmful to
wildlife and the environment. Empty containers contain toxic residues and pose a special
waste problem, which some regions are
addressing with waste collection
programmes.
Consumers have concerns about undesirable
pesticide residues in food, water and the
environment. Purchasing companies generally
accept the use of fumigants and pesticides
where they meet the regulatory requirements
for application and residues. However, some
major supermarkets are demanding minimal
residues and reduced reliance on pesticides.
Registration and regulatory restrictions
Fumigants and other pesticides have to be
registered (approved and permitted) by
national and/or state pesticide regulation
authorities, and regulation may restrict sale,
use and disposal. Authorities normally specify
the crops for which particular products can
be used, the maximum application rates, and
other conditions that may limit their use.
To find out whether a fumigant or pesticide is
registered for your crop/application, contact the
pesticide registration authority at the appropriate national or state level. Agrochemical suppliers can also provide information on the
regulatory status of chemicals, but the information may not be up to date or reliable.
The sale of pesticides is also restricted by a
number of international agreements. An
international code of practice developed by
the Food and Agriculture Organization of the
United Nations provides guidelines for the
marketing and use of pesticides. Certain pesticides are subject to the Rotterdam
Convention, an international agreement that
requires Prior Informed Consent or PIC procedures to be followed before import. A new
agreement will limit specific Persistent
Organic Pollutants (POPs); international trade
and disposal of pesticides is subject to the
Basel Convention on hazardous wastes.

In practice, overall costs may be higher than
with MB, because several treatments or combinations are often required to replace MB.
Where specially adapted machinery is necessary, capital costs will be higher. Labour costs
vary and can be higher than MB if additional
soil preparation is necessary.

Advantages
Soil amendments stimulate the activity
of beneficial soil organisms and lead to
other soil changes that directly or indirectly reduce or suppress pests.
Pest suppression can continue for several
seasons.
Organic matter improves soil texture,
providing crop nutrients and reducing
fertiliser costs.
Raw materials that are suitable as soil
amendments are often non-toxic and do
not require special safety training.
A wide range of waste materials can be
used as amendments.
Disadvantages
Amendments suppress specific
pathogens and nematodes and do not
control weeds and insects, so they need
to be combined with other techniques.
Amendments are normally applied in
large quantities.
Use may be limited to localities where
materials are readily available, otherwise
transport costs may be unacceptable.
It is necessary to have quality controls
and to avoid materials that may be contaminated with undesirable components
such as heavy metals or weed seeds.
Know-how is required for effective use;
efficacy varies with the type of soil and
type of amendment.
Soil amendments are organic materials, such
as crop residues and waste materials from
forestry and food processing industries.
These amendments decompose when they
are added to soil, supporting and promoting
the activity of beneficial soil microorganisms
that suppress certain pathogenic fungi and
nematodes.
While MB kills pathogens very quickly,
amendments and composts typically suppress
or eradicate pathogens slowly over a long
period of time (Cohen et al 1998, De Ceuster
and Hoitink 1999). Amendments, therefore,
must be applied well before pathogens reach
populations capable of causing losses, and
this requires more management. Use of soil

4.4 Soil amendments
and compost
61
amendments requires careful monitoring for
particular pest problems, with greater attention to pest biology. To replace MB, amendments generally need to be used with other
control techniques as part of an IPM system.
62
Amendments are incorporated into the soil in
substantial quantities, normally in excess of
30 t/ha. Use of locally available waste materials can keep transport costs at an acceptable
level. Soil amendments should be derived
from materials that are free from plant pests
and pathogens, or they should be composted
at temperatures that kill pathogens. They
must also be free from contaminants that
could cause phototoxicity (toxicity to plants)
or undesirable food residues.
Substances that can be used as soil amendments include the following:
Compost made from a wide variety of
waste materials, e.g. crop residues and
animal manure.
Composted sewage sludge, if it is free
from pathogenic organisms and heavy
metals.
Mushroom industry waste.
Animal manures and wastes from meat,
dairy and poultry production.
Green manures, i.e. crops that are specially grown and incorporated into the
soil while they are still green.
Oil cakes or oilseed meals such as cottonseed meal or soy meal.
By-products from food processing, e.g.
fruit skin, pulp and culls.
By-products from fish processing, e.g.
fishmeal, fish emulsion, shellfish waste,
and chitin from the pulverised shells of
crabs and lobsters.
By-products from the forest and paper
industries, e.g. waste wood, bark, sawdust and paper mill digests.
When amendments are added to soil, they
are decomposed by microorganisms. This
stimulates microbial activity and increases the
total number of soil fungi and bacteria by
100- to 1000-fold, while decreasing the number of pathogens (Lazarovits et al 1997, Anon
1997). The chemical composition and physical
properties of the amendments determine the
types of microorganisms involved in decomposition and hence their efficacy.
Certain nitrogen-rich amendments are
capable of being converted in the soil to
nitrate or yielding nitrous acid directly. Such
amendments can kill the microsclerotia of
Verticillium dahliae and other soil-borne
pathogens, providing an effective broad-spectrum alternative to MB for certain soils
(Tenuta and Lazarovits 1999). Examples of
these amendments include poultry manure,
soy meal and feather meal. Soil pH values
above 8.5 are required for the ammonia
mechanism, while pH values below 5.5 are
required for the nitrous acid mechanism
(Tenuta and Lazarovits 1999). The more successful nitrogen-rich amendments are reported to be ones that raise soil pH temporarily
above 8.5 for a few weeks, allowing ammonia to be effective, and then falling back to a
pH below 5.5, allowing the action of nitrous
acid for 2 to 6 weeks (Table 4.4.1).
Composting of organic materials speeds up
the rate at which they decompose. Compost,
used for centuries to maintain plant health
(Hoitink et al 1997), can be made from many
types of organic waste, provided the wastes
are free from harmful contaminants or diseased crop residues. Each type of compost
has its own characteristics.
A compost pile, typically several metres wide,
is made of layers of crop residues and animal
manure, kept slightly moist but not wet. The
site must be protected from sun and windblown seeds. Raw organic material is converted into compost, decomposed by the action
of bacteria and fungi. Temperatures in the
centre of the pile can reach 60 to 70°C,
Compost is widely used in the Colombian cut
flower industry and is typically made in four
to five months. Production time is reduced by
several practices:
Cutting raw materials in small pieces
(< 4 cm long).
Selecting raw materials to provide a
carbon/nitrogen ratio of about 30:1.
Adding material containing beneficial
microorganisms, such as old compost
or manure.
Controlling pH and moisture.
Turning the pile frequently.
Disease-suppressive compost is also used
by some cut flower producers in Colombia,
where a microbial broth is made on-farm and
added to the compost pile to increase the
variety and numbers of beneficial soil
microorganisms. The resulting compost helps
to suppress many soil-borne pathogens, provides nutrients and improves soil texture.
A number of factors must be controlled for
consistent effects. These include the composition of the organic matter; the type of
composting process, if any; the stability or
maturity of the material; available plant nutrients; application rates; and time of application. Some important issues to consider are
outlined below:
Large quantities of amendments are
required. This makes them expensive,
unless cheap or waste materials are
available locally.
Because the effectiveness of nitrogenrich amendments varies from one soil to
another, amendments can give inconsistent control of pathogens from field to
field. Scientists in Ontario have developed a pre-application soil test that will
test the suitability of a specific amendment for the field (Tenuta and Lazarovits
1999).
The composition and quality of raw
materials varies greatly and must be
managed with quality control systems.
Amendments and composts prepared
from manures may contain high
amounts of sodium and chlorides.
Application of such materials well ahead

killing some weed seeds and pathogens.
Pests in cooler sections of the pile are not
killed, but many pathogens will be killed if
the compost is turned or mixed frequently
and thoroughly. Turning also prevents the
development of undesirable ‘sour’ compost
and offensive odours. Composting time can
vary from three weeks to many months,
depending on the method.
63
of planting time, however, can alleviate
problems with these materials.
The level of plant nutrients may vary
from batch to batch, so crop fertilisers
must be adjusted to compensate.
Excessive nitrogen can be a problem
with manures, while nitrogen deficiency
is a danger with wood residues. In some
cases, amendments need to be diluted
by mixing with other types of
amendments.
64
The level of decomposition of amendments and composts affects pest control.
Fresh organic matter does not support
beneficial microorganisms, even when
inoculated with the best strains. High
concentrations of free nutrients, such as
glucose or amino acids, in fresh crop
residues repress the production of
enzymes required for beneficial organisms such as Trichoderma. Composts
must therefore be stabilised well enough
and colonised to the degree that they
support microbial activity (De Ceuster
and Hoitink 1999).
The variability of amendments and composts can make them difficult for farmers to use successfully, but this can be
addressed by introducing quality controls
on production and establishing guidelines for the use of specific formulations
(De Ceuster and Hoitink 1999).
In addition to suppressing pests, soil amendments provide the major advantages of
improving soil texture and structure and pro-
viding a range of nutrients for plants, which
can save fertiliser costs.
Current uses
Soil amendments were traditionally used as a
method of controlling soil-borne pests and
are now receiving renewed attention.
Compost, for example, has reduced or eliminated MB use in a number of large commercial nurseries in California (Quarles and
Grossman 1995). In Morocco, cattle manure
reduces the incidence of Fusarium and
Verticillium wilts in tomatoes (Besri 1997).
Other examples of commercial use of soil
amendments are provided in Table 4.4.2.
Biofumigation is another recently developed
alternative, employing specific types of
amendments that produce fumigant gases
when they decompose (Kirkegaard et al
1993, Mathiessen and Kirkegaard 1993, Bello
1998, Bello et al 1997, 1998 and 1999).
Brassica crop residues, for example, produce
volatile chemicals such as methyl isothiocyanate and phenethyl isothiocyanate
(Gamliel and Stapleton 1997). Biofumigation
stimulates soil microbial activity and increases
populations of nematodes that feed on bacteria or fungi and populations of benefical
predatory nematodes (MBTOC 1998).
Biofumigation is more effective when combined with solarisation, because the plastic
traps gases and raises soil temperatures (Bello
et al 1998). It has been used successfully in
the production of bananas, tomatoes, grapes,
melons, peppers and other vegetables (Bello
et al 1999, Sanz et al 1998).

Research on how amendments work in different types of soil is currently underway, and
improved understanding in this area could
increase efficacy and reduce application rates
and related costs.
Material inputs
Organic materials (30 - 100t/ha).
Transport for bringing material to the
farm and equipment for incorporating
amendments into the soil.
For biofumigation, plastic sheets laid
mechanically or by hand.
Local sources of cheap organic matter,
such as wastes or by-products.
Quality control to ensure that harmful
contaminants are avoided.
For compost: adequate space and wellaerated areas, careful sorting of residues
and regular turning and management.
Good management to ensure the
efficacy of disease-suppressive compost.
Know-how, training and careful
management.
Pests controlled
Soil amendments do not control weeds and
soil insects, but until the 1930s, organic
amendments consisting of animal and green
manures were among the principal methods
of controlling soil-borne diseases. The following are among the soil-borne fungi and
nematodes that can be controlled or suppressed by various types of soil amendments:
Blood or fishmeal incorporated into the
soil at 10 tonnes per acre has been
shown to completely inhibit Verticillium
infection in tomatoes (Anon 1997).
Poultry manure, urea, soy meal and
other amendments that can be convert-
ed to nitrate or HNO2 in the soil can kill
the microsclerotia of Verticillium dahliae
(Tenuta and Lazarovits 1999).
Composted softwood and hardwood
bark reduce pathogens such as Pythium
ultimum.
Composted bark amendments control
Pythium and Phytophthora root rots
most effectively in container media
(Hardy and Sivasithamparam 1991,
Ownley and Benson 1991); however the
physical and chemical properties of the
mixes must be ideal for this to occur.
A composted pine bark mix fortified
with Flavobacterium balustinum and
Trichoderma hamatum is very effective in
controlling Fusarium wilt of cyclamen
and Rhizoctonia diseases as well as
Pythium and Phytophthora root rots in
potted greenhouse crops (Krause et al
1997).
Rhizoctonia solani is not normally controlled in the first few weeks after applying amendments but can be controlled
by well-cured composts or by incorporating composts in the fields well ahead of
planting (Kuter et al 1988, Tuitert et al
1998).
Fusarium crown rot of Chinese yam is
suppressed in sandy soil amended with
composted larch bark, replacing MB if a
spray of benomyl is also applied to the
soil at planting (Sekiguchi 1977).
Chitin increases populations of beneficial
actinomycetes and other microorganisms
and suppresses some plant-parasitic
nematodes (MBTOC 1998, Chaney et al
1992).
Cattle manure application (>60t/ha) has
been shown to reduce incidence of
Fusarium and Verticillium wilts in tomato
in Morocco (Besri 1997).
Disease-suppressive compost used in
Colombia helps to suppress many soilborne pathogens in cut flower production (Batchelor 1999).
65
The action of amendments can be relatively
rapid. Nitrogen-rich amendments, for example, kill microsclerotia within 7 to 10 days (at
7 to 24°C) when the soil pH is high (Tenuta
and Lazarovits 1999).
66
Organic amendments need to be combined
with other techniques in order to give yields
equal to MB fumigation. Repeated trials in
nurseries producing Douglas fir and ponderosa pine in Oregon and Idaho USA found
that bare fallow with sawdust soil amendments resulted in seedling quality and quantity comparable to fumigation (USDA 1999).
Other examples of yields from soil amendments used in combination with other techniques are provided in Table 4.4.3.
Suitable crops
Soil amendments can be used for most horticultural crops, although some materials, such
as municipal compost, may be suitable only
for non-food crops. Amendments and compost can be used in open fields, greenhouses,
seedbeds and nurseries. They can be used for
single and double cropping.
The use of soil amendments is restricted to
climates and times of year when temperatures are conducive to biological activity. Soil
amendments can be used with many different types of soil, but some materials need to
be matched to specific types of soil. They
improve the texture of poor soils.
Soil amendments are not normally toxic in
themselves, although materials like sewage
sludge can contain organisms that are pathogenic to humans and undesirable for use with
crops. Certain amendment materials could
generate noxious substances if improperly
handled. There are no risks of toxicity if
amendments are selected and used properly.
Safety training is desirable for anyone handling animal wastes. Materials that contain or
generate contaminants must be avoided. For
example, sewage is not suitable as a soil
amendment if it contains heavy metals or
pathogenic microorganisms.
Provided soil amendments are properly selected, there will be no undesirable residues in
food or the environment.
Phytotoxicity
A waiting period of approximately two to
four weeks may be necessary before planting
crops. For certain types of amendments and
crops the waiting period may be substantially
longer. Compost must be produced under
quality control standards to exclude unsuitable raw materials, maintain aerobic conditions, and prevent the compost from
producing certain acids that can be toxic to
plants.
Soil amendments have a positive effect on
beneficial organisms.
Ozone depletion
Soil amendments are not ODS.
consumption
The energy use associated with transportation
of organic amendments can be minimised by
using local supplies.
Soil amendments normally come from renewable resources. Use of soil amendments does
not generate waste. On the contrary, it provides an opportunity to use waste materials
constructively.
Soil amendments are very acceptable to consumers because they are seen as natural
treatments. They are increasingly acceptable
to companies that purchase fresh produce,
provided that quality controls are used.
Soil amendments do not require registration
as pesticides. However, it is desirable that
health authorities place restrictions on the
types of materials that can be used as
amendments to prevent use of materials containing undesirable contaminants or dangerous microorganisms. The US California
Department of Food and Agriculture, for
example, regulates the manufacture, labeling
and marketing of amendments in the state.
system
What sources of clean, cheap, waste
organic materials are available locally?
Which available materials will control
these pests?
What amounts needs to be applied and
how?
What is the most effective time to apply
the amendments?
What other measures need to be taken
to control the pests?
Availability
Costs depend mainly on the source of
the amendment and its transportation.
To be cost-effective, soil amendments
generally need to be waste materials or
by-products from local sources.
Material costs can be similar to or
cheaper than MB if amendments are
waste products; the costs are likely to be
higher than those associated with MB if
amendments are specially manufactured.
Organic waste materials are available in
most areas.

incorporating organic amendments into

4.5 Solarisation
Advantages
Relatively simple application procedures.
Cheaper than MB.
Non-toxic treatment; no health or safety
problems for users.
Registration is not required.
70
Promotes beneficial microorganisms in
the soil.
Tends to increase soil fertility; increases
soluble nitrogen (NO3, NH4), calcium,
magnesium and potassium.
Long-term beneficial effects on disease
control.
Disadvantages
Requires time for treatment, with land
typically taken out of production for four
to seven weeks.
Limited to regions with sufficient solar
radiation.
Does not control all soil-borne pests, so
may need to be combined with other
techniques.
Needs to be adapted to the local crop
production systems.
Like MB fumigation, it generates plastic
waste.
In solarisation treatments, transparent plastic
sheets are placed on the soil to trap heat
from the sun and raise the soil temperature
to levels that kill or suppress pests. The thin
sheets are made of UV-resistant polyethylene
about 30 to 100 microns thick. Treatment is
carried out prior to planting crops and can
also be applied as a post-plant treatment in
orchards and vineyards.
The soil is normally prepared by disking, rototilling or otherwise turning to break up clods.
Large rocks, weeds or other debris that may
raise or puncture the plastic sheets are
removed. The land surface is smoothed so
the plastic can rest directly on the soil, since
air pockets reduce the heating effect. The
sheets are then placed on the soil by hand or
machine; several techniques are described in
Grinstein and Hetzroni (1991) and Elmore et
al (1997). Care must be taken to avoid
stretching or tearing the plastic. If holes or
tears do occur they must be patched with
clear plastic tape, otherwise solarisation will
not be effective.
The sheets may cover an entire field or greenhouse floor or be placed only along the strips
or rows where crops will be planted. Sheet
edges are sealed with UV-resistant glue or
buried and covered with soil. Thermometers
can be placed in the soil at specific depths to
record soil temperatures during the treatment. Typically, the plastic sheets remain in
place for four to seven weeks. Treatment

The aim of solarisation is to ensure that soil
at the depth below root level reaches at least
about 40°C for the required number of days.
Many soil pests are killed at temperatures
above 33°C, although others require significantly higher temperatures (Elmore et al
1997). In general, good results can be
achieved if soil temperatures of 47, 45, 43
and 39°C are achieved at soil depths of 10,
15, 20 and 30 cm, respectively (Katan 1996,
1999).
Adequate soil moisture is important for conducting the heat through the soil and to
make weed seeds and pathogens vulnerable
to heat. At the start of the treatment, the soil
should be saturated to at least 70% of field
capacity in the upper layers and moist to
depths of 60 cm (Elmore et al 1997). If soil
moisture drops to less than 50% of field
capacity, or if the soil is well drained, it may
be necessary to irrigate during the solarisation treatment. Over-watering, however, must
be avoided because it cools the soil and
reduces the efficacy of solarisation.
When removing sheets, care must be taken
to ensure that untreated soil does not contaminate treated soil. If laid manually and
handled carefully, sheets may be used for
more than one season.
As noted earlier, there are several major variations of solarisation:
Complete cover of the area
Plastic sheets are laid in a continuous surface,
covering the entire field or greenhouse floor.
Edges may be joined with UV-resistant glue
or by overlapping and burying the edges. If
beds are formed after solarisation, deep
tillage must be avoided because it may bring
untreated soil to the surface. After solarisation the sheets are removed and crops are
planted as normal. Complete cover is recommended where the soil is heavily infested
with pathogens, because it is more effective
than strip solarisation.
Strip solarisation
Beds are formed in the soil and plastic sheets
are laid along them, forming strips on the
field. Wide strips are more effective than narrow strips, because pathogens are not controlled in the uncovered soil between strips. It
is recommended that strips be a minimum of
75 cm wide, but beds up to 1.5 m wide are
more effective and allow several crop rows to
be planted on each bed (Elmore et al 1997).
When solarisation has finished, the plastic

times may be shorter, however, for certain
susceptible pests or for crops with very shallow roots. Solarisation of containerised substrates or growth media and closed
greenhouses may take only a few days during
strong summer heat (Elmore et al 1997).

may be painted and left on the soil to serve
as a mulch. Strip solarisation is generally
cheaper than complete cover. It is effective
against certain weeds, but long-term control
of fungi and nematodes may not be suffi-
cient, because pests in the untreated soil can
spread to treated areas. Strip solarisation is
not recommended for soil that is heavily

Space solarisation
This technique is used in greenhouses to kill
pests surviving in crop debris in the structure
of a greenhouse. If the greenhouse surface is
dusty, it must be washed before the treatment begins, to allow solar radiation to penetrate. The greenhouse is then closed during
summer time, so that inside air temperatures
reach 60 to 70°C. Equipment such as tomato
stakes or canes can also be disinfested in
closed greenhouses.
The treatment time for solarisation varies
according to the target organisms, soil condi-
tions and temperature. Under Mediterranean
conditions, for example, a period of 30 to 40
days between June and September is suitable
for solarization for many purposes (Katan
1999). As a general rule, the longer the solarisation period, the deeper the effect in the
soil. See Table 4.5.1 for examples.
The best control of pests is usually achieved
in the upper 10 to 30 cm of soil. The efficacy
of solarisation can be increased and/or treatment time reduced by using a double layer of
plastic or by combining solarisation with one
of the following:

Solarisation is used commercially for a variety
of crops in warm climates. For example, solarisation has been used for more than a decade
in California USA for field, vegetable and
flower crops and in orchards, vineyards,
greenhouses and landscapes (Elmore et
al 1997). Other examples are given in

Pests controlled
Solarisation can control many soil-borne pests
such as fungi, weeds, insects and mites
(Katan and DeVay 1991, DeVay et al 1991).
In addition, solarisation frequently promotes
the growth of beneficial soil microorganisms
that reduce populations of soil pests during
the growing season. Tables 4.5.3, 4.5.4 and
4.5.5 give examples of nematodes, fungi,
bacteria and weeds controlled by solarisation
in California, USA. Some of these results have
been verified in other countries, such as
Israel, Jordan, Greece and southern Italy
(Katan 1996). The technique must be adapted to different climatic regions and cropping
systems.
Certain pathogens, such as Verticillium fungi
and Ditylenchus nematodes, are sensitive to
solarisation and are more easily controlled by
it. Solarisation controls many annual weeds
effectively but does not control perennial
weeds that have deeply buried roots or rhizomes, unless the heat penetrates to those
levels. In some areas solarisation does not
adequately control root-knot nematodes and
heat-resistant pests, such as nutsedge weeds
and certain fungi. To control these pests,
solarisation should be combined with other
techniques or used as part of an IPM system.
Table 4.5.6 gives examples of nematodes,
fungi, bacteria and weeds that are not controlled, or are not controlled reliably, by solarisation.
Where the technique is applied properly in
the appropriate climate, solarisation results in
yields similar to those achieved with MB fumigation (see Table 4.5.7).
Solarisation leads to changes in the physical
and chemical features of soil, often improving
the growth and development of plants. It
releases soluble nutrients such as nitrogen,
calcium, magnesium, potassium and fulvic
acid, making them more available to crops
(Elmore et al 1997).
Solarisation is suitable for all horticultural
crops, including orchards and vineyards. For
perennial crops solarisation can be applied as
a post-plant treatment. It can be used in
open fields, greenhouses, tunnels, seedbeds
and nurseries. Solarisation can also be used
to control pests in substrates, containers or
cold frames. In these cases, the soil or substrates can be placed in bags or flats covered
with transparent plastic or in layers that are
75
7.5 to 22.5 cm wide sandwiched between
two sheets of plastic (Elmore et al 1997).
The US California Department of Agriculture
has approved a protocol for using solarisation
to kill nematode and fungal pests in soil and
containers used for raising clean nursery
stock. The soil temperature must be raised by
solarisation to 70°C for at least 30 minutes.
76
Use of solarisation is often limited to production systems that allow a downtime of four
to seven weeks for the treatment, unless
combined with other treatments.
Solarisation is suitable for many soil types,
although water must be applied during treatment in sandy soils. Its use is limited to geographical regions that have sufficient solar
radiation to achieve high temperatures in the
soil. Highest soil temperatures are attained
when days are long, air temperatures are
high, skies are clear, and there is no wind
(Elmore et al 1997). Clouds and wind diminish the heating effect. Solarisation is most
effective in warm, sunny locations. It has also
been used successfully in cooler areas during
periods of high air temperatures and clear
skies. In cooler climates, solarisation of greenhouses, nurseries, seedbeds and containerised
soil or substrates is more effective than solarisation of fields (Katan et al 1998).
Solarisation treatments do not pose any safety risks to users or local communities.
Safety measures are not required. No safety
training or safety equipment is required.
Solarisation does not produce undesirable
chemical residues in air, water or food.
However, plastic waste may remain in soil and
the surrounding environment, as is the case
with MB fumigation sheets.
Phytotoxicity
The treatment does not normally produce
toxicity problems for crops.
Many beneficial soil organisms recolonise the
soil rapidly after solarisation. Solarised soil
frequently becomes more pest-suppressive
due to the establishment of fluorescent
pseudomonads (Katan 1996). Solarisation
shifts the soil population in favour of beneficial organisms and makes it more resistant to
pathogens than non-solarised or fumigated
soil (Elmore et al 1997).
Ozone depletion
Solarisation does not use ODS.
consumption
Energy is used for production of plastic
sheets, any mechanical application used and
recycling of plastic, where available. Energy
consumption is less than that with MB
fumigation.
Like MB, solarisation sheets generate significant quantities of waste plastic. In a few
regions, including parts of Brazil, Italy and
Greece, agricultural plastic recycling schemes
have been established.
Solarisation is very acceptable to markets and
consumers, because it is a non-chemical
treatment and does not leave undesirable
residues in food.
Solarisation does not require regulatory
approval.
Strip solarisation is cheaper than complete cover but less effective.
Material costs are lower than for MB.
Plastic sheets that are 50 microns thick
are generally cheaper than 100-micron
sheets, although the thicker sheets may
be re-used.
Manual application allows re-use of plastic, whereas mechanised application precludes re-use.
Labour is about 10 to 20 man-days for
manual cover of 1 ha with continuous
sheets, about 3 man-days/ha for
mechanical application, or about 0.5
man-days/ha for mechanical strip
application.
The total cost of solarisation is normally
less than MB application.

utes at 72°C). This lower temperature controls most pests but does not eliminate all the
organisms in the soil. Steam treatments are
fast and there is no waiting time because
crops can be planted as soon as the soil has
cooled.
Controls the same range of pests as MB.
Treatment time is rapid compared to MB
and other alternatives.
Crops may be planted immediately after
treatment.
Some steam methods are easy to use.
Negative pressure and fink systems can
provide deep soil treatments.
Disadvantages
Significant initial capital investment,
unless a boiler is hired.
Consumes more energy than does MB.
Requires a supply of water at treatment
time.
Some older methods are complicated to
apply.
High-temperature methods (above 82°C)
can produce phytotoxicity.
Sterilization method (90 to 100°C) creates a ‘biological desert’ in the soil, like
MB.
Boilers can be difficult to transport on
poor roads.
When the soil temperature is raised to at
least 65°C for 30 minutes, heat kills many
pathogenic fungi, bacteria, nematodes and
weed seeds. Steam treatments are traditionally conducted at temperatures between 60
and 100°C. Soils may be sterilised at high
temperatures for short periods (a few minutes
at 90 to 100°C) or pasteurised at lower temperatures for longer periods (such as 30 min-
The soil is prepared for steam treatment by
removing clods and covering with material
such as insulated sheets. A conventional boiler or steam generator provides the steam.
Steam can be released onto the soil surface,
ploughed or raked into the soil, but it is normally more effective to inject steam into the
soil or to pull steam through the soil by negative pressure. The efficacy of the treatment
requires an application method that distributes steam evenly through the soil and carries
it to sufficient depths to kill pests. As with
other techniques, steam treatments require
know-how and attention to detail during
application.
Steam may be applied alone or mixed with
air. Aerated steam has the advantage of
being cooler (e.g. 72°C), moving faster and
more uniformly through soil and, in some
cases, reducing energy consumption.
Available boilers range in capacity from about
65 kg/hour to at least 4,500 kg/hour for
treating larger areas. Large areas are treated
in batches, one plot at at time. Boilers can be
fixed in one place or moved from one area to
another. In some countries, companies provide mobile steam boilers as a contracted
service for many greenhouses.
The following are among the many varieties
of steam treatment:
Sheet steaming
The traditional method of steaming is to
cover the soil with sheets, seal the edges and
release steam under the sheets for about 4 to
8 hours. This method provides a shallow
treatment and is very inefficient in energy
use. It does not control pests reliably unless
carried out with great care and skill.
Does not entail the use of toxic
chemicals.

Negative pressure method
This fixed system is generally preferable to
older techniques because it is more energyefficient and disperses steam more evenly in
soil. Perforated drain pipes are laid in the soil
at intervals of 1.6 to 3.2 m, depending on
the density of the soil structure. Normally, a
drainage pit is constructed for collecting
excess water. A cover is placed on the soil
surface and steam is introduced beneath it. A
simple fan is placed at the end of the drainpipe network to create a negative pressure,
pulling the steam down through the soil and
raising the temperature to 70 to 80°C, even
at the deepest levels. Steam is applied for
one to two hours at a high rate and then
reduced to a low rate for several hours. The
treatment typically takes four to five hours.
Fink method
This method uses principles similar to those
of the negative pressure system. Rubber pipes
are inserted vertically into the soil and a pipe
grid is laid on the surface, under sheets. A
fan creates suction in the pipes, allowing
steam to penetrate to about 50 cm depth.
The Fink method takes about five to six hours
and has similar advantages to the negative
pressure system. In addition, it can be moved
around to treat other plots.
Hood or metal box method
In this method a shallow, inverted aluminum
or steel box is pressed into the soil surface.
The large box may cover an area of approximately 6 x 2.5 m. Steam is applied inside the
box for 20 to 25 minutes, so that the top 20
to 25 cm of soil reaches about 80°C. In automated systems, a winch moves the machine
along the bed, and the box is raised and lowered by pneumatics. This type of system may
be operated by one labourer and can treat
field areas of up to 2,000 m2 in 10 hours. It
is more energy efficient but provides a shallow treatment suitable only for certain crops
and pests.
Steam chambers
Airtight chambers or steam boxes provide
rapid steam treatments for soil, substrates
and agricultural equipment. In some nurseries, soil is placed in containers and forklifted into steam boxes for treatment. In a
few countries mobile steam chambers —
trucks fitted with boilers and large air-tight
chambers — serve many greenhouses in a
locality. Substrates are removed from plastic
wraps or containers and placed inside the
chamber. Steam from the mounted boiler is
introduced into the sealed chamber, until the
substrates have reached the required temperature. After cooling, the substrates are reused in the greenhouse.
Steam ploughs
Negative pressure steam chambers
Super-heated steam, up to 160°C, is forced
through material in a chamber, and negative
pressure sucks out condensed steam. Heating
time is very short, approximately five minutes.
This system can be used for substrates, peat,
pots, trays and certain plants. At present
there are about 12 chambers operating in
Belgium and the Netherlands, each with the
capacity to treat about 2.5 hectares of substrate in 24 hours. A smaller-scale negative
pressure chamber is used for nursery equipment, trays and plants in Norway.

Various forms of steam ploughs are available.
The “NIAE” mobile grid, for example, has a
transverse leading blade, which breaks up the
soil across the width of the grid, enabling
steam to spread sideways from perforated
pipes. The motion of soil over the transverse
blade encourages steam penetration, forming
a bow wave that opens up the soil vertically.
The NIAE grid moves at 7 to 8 m per hour,
treating a width of about 1.7 m and a depth
of 40 to 45 cm of soil.

In general, negative pressure and fink steaming are preferable to traditional sheet steaming, because they disperse steam more evenly
in the soil, give better results and use less
energy. Hood and chamber methods are also
efficient for specialist applications. Older
techniques can take soil temperatures too
high, sterilising soil and releasing heavy metals and phytotoxic materials. They also give
uneven results or fail to reach sufficient
depth. Negative pressure methods give better
results than traditional sheet methods on clay,
peat, loam and sandy soils (Ellis 1991). See
Table 4.6.1 for a comparison of some greenhouse methods.
Current uses
Steam is widely used for greenhouses, nurseries, bulk soil, containerised soil and substrates. It is also used in a limited number of
small-scale fields. In the Netherlands, up to
10% of cucurbit production utilises negative
pressure steaming (De Barro 1995), for example, and in the USA small portable steam
generators have been used successfully in
greenhouses for more than 20 years (USDA
1997). Table 4.6.2 provides other examples of
commercial uses.
Improved versions of steam ploughs.
Automated equipment that lifts the top
layer of soil and moves it through a
steam bed for open field applications.
Material inputs
Sheet steaming requires:
Water.
Boiler or steam generator and fuel.
Heat resistant pipes to distribute steam
over soil surface.
Heat resistant insulated sheets to cover
soil.
Thermocouple to monitor soil temperature.
Negative pressure steaming requires:
Equipment listed above.
Perforated pipes (preferably polypropylene pipes of about 60 mm diameter)
buried permanently under the soil.
Fan with a capacity of 1,800 m3/hour for
an area of 2,500 m2; capacity of 1,000
m3/hour for an area of 1,000 m2.
Pump and sump.
Supply of water at the time of year
when steam treatments are carried out.
Capital for initial investment.
Roads suitable for transporting heavy
boiler equipment.
Know-how and training.
Pests controlled
Steam treatments control a wide range of
soil-borne pests, including nematodes, fungal
pathogens, weeds and insects. Some steam
methods control a wider range of pests than
MB. It is necessary to select a steam delivery
method that will control pests to the required
depth.
Few organisms can withstand a moist soil
temperature of 65°C maintained for ten minutes (Ellis 1991). Nematodes, insects, many
fungi, weed seeds and many bacteria are
killed at even lower temperatures (Table
4.6.3), but higher temperatures are recommended to deal with heat-tolerant pests and
cool patches that occur in soil. Efficacy
depends mainly on the soil temperature,
treatment duration and application method
to provide a thorough distribution of heat in
the soil. In the Netherlands, for example, a
temperature of 70°C maintained for 30 minutes is generally recommended to control
soil-borne pathogens (Runia 1983, Ellis 1991).
Lower temperatures could be applied for a
longer time or higher temperatures for a
shorter time.
Where the technique is properly applied,
yields are equal to those achieved with MB.
Steam can be used in greenhouses, seedbeds
and small-scale field nurseries, for containerised soil, substrates (e.g. perlite, rockwool,
polyurethane foam, rice hulls, compost), nursery tools, pots and surfaces that are contaminated with pathogens. Steam can be
economically viable for high value crops such
as ornamental bedding plants, potted foliage,
flowering house plants, fresh cut flowers and
greens, bulbs, container perennials, and
greenhouse vegetables (EPA 1997). Steam
treatments are particularly suitable for multicropping, because treatment is rapid and
waiting periods can be avoided.
Steam can be used in all climates, from cool
temperate to tropical. UNIDO has carried out
effective demonstrations of steam in regions
as diverse as Argentina, China, Guatemala,
Syria and Zimbabwe (Castellá 1999). Steam
treatments are suitable for clay, loam, sand
and substrates. Steam-treating peat is difficult
but feasible.
Steam is not toxic. The associated heat, however, can pose a risk of burns if handled
improperly or if accidents occur, so boilers
and operating procedures must meet safety
standards. Steam treatments do not pose
risks to the health of local communities or
farm workers in fields next to the treatment
areas.
Measures need to be taken to prevent users
from coming into contact with steam. In
addition, safety training and safety equipment are needed for the use of boilers.
Steaming to high temperatures (about 100°C)
can lead to undesirable levels of ammonia
and nitrite in soils that have been fertilised or
have a high content of organic matter. This
problem can be avoided by keeping the soil
temperature below 82°C.
Phytotoxicity
When certain soils are heated to about
100°C, manganese, ammonia and nitrites
may be released. Excess manganese can produce problems of phototoxicity in crops, but
this problem is normally avoided by keeping
treatment temperatures below 82°C.
Like MB, steam has a significant negative
impact on beneficial organisms in the soil. If
soil is heated to 100°C, virtually all organisms
are killed, creating a biological desert. The
impact is reduced if lower temperatures are
used and the soil is pasteurised rather than
sterilised.
Ozone depletion
Steam is not an ODS.
consumption
Steam generation normally consumes more
energy than does MB fumigation. Negative
pressure systems are generally considered
energy-efficient steaming methods, because
they use less than half the energy of traditional sheet steaming (Ellis 1991). In some
cases it is possible to use alternative fuel
sources, such as methane from landfills, biogas, hot water from electric power stations,
sawdust, wind or geothermal vents (EPA
1997, Davis 1994).
Some steam techniques use significant
amounts of water, making them unsuitable
for areas with limited water supplies.
83
Steam is very acceptable to supermarkets,
purchasing companies and consumers,
because it is a non-chemical treatment and
does not leave pesticide residues in food.
Registration and regulatory approval are not
required for steam treatments for soil.
However, boilers must meet all necessary
safety standards.
84
Cost considerations
often cheaper. Labour time for treating
1000 m2 can vary from 5 to 80 hours,
depending on the steaming method.
Questions to ask when selecting
the system
What area needs to be treated?
What soil depth does the treatment
need to reach?
What is the best method for distributing
steam evenly and to the necessary
depth?
The initial capital cost of steam is substantially higher than the cost of MB.
Depending on capacity, a boiler may cost
from about US$ 4,000 to more than US$
100,000. A boiler with an output of 90
kg steam per hour costs approximately
US$ 5,700 in the USA. A portable electric boiler with the same capacity costs
about US$ 4,665 in South Africa.
What boiler size is required?
In the USA, a farm that usually fumigates 12 hectares per year can recover
the capital costs of steam in 1 year
(Quarles 1997).
What are the costs and benefits of different methods of steam treatment?
Where investment capital is not available, growers could consider hiring a
boiler instead of purchasing it (Ellis
1991).
Operating costs of steam can be similar
to MB in northern Europe (De Barro
1995), while the operating costs for
steam treatments in the USA are less
than the typical cost of US$ 1,000 to
1,500 per acre for MB fumigation
(Quarles 1997).
In the Netherlands, the annual cost of
using steam in greenhouses is in the
same range as the cost of MB fumigation (De Barro 1995).
Labour costs for manual steaming are
generally higher than the costs of MB,
while labour for automated steaming is
In the long-term, is it cost-effective to
hire a boiler or to buy one?
Is a fixed or movable steam system more
appropriate?
How will measurements be taken to
assure that sufficient temperature has
been reached at the required depth?
Availability
Boilers are manufactured in many countries,
so it is normally possible to purchase one
locally. The materials for negative pressure
and Fink systems are simple and readily available, while steam ploughs and hood systems
involve specialist equipment and are not yet
widely available.

4.7 Substrates
Advantages
Often give higher yields than MB.
Increase opportunities for extending the
growing season and harvesting at times
when prices are better.
Produce more uniform fruit and
vegetables.
Non-toxic to farm workers and local
communities.
Can be adapted to suit a wide variety of
economic situations, ranging from lowcapital systems that are simple to use, to
capital-intensive systems that require
substantial management.
Substrates replace soil by providing a clean
medium for plants to grow in. Substrate
materials can be taken from a wide variety of
sources, if the sources are free from pests and
pathogens and free from contaminants that
could cause crop toxicity or undesirable food
residues. Substrates also need to have pore
spaces and other characteristics that allow
good retention and movement of nutrients,
water and air for the plant roots. Where necessary, several materials can be mixed together to create a substrate with optimum
characteristics. If the raw materials are not
free from pathogens, they can be treated
with steam (see Section 4.6) or solarised (see
Section 4.5) prior to use.
Water-based hydroponic systems require
specialist know-how and may fail if not
well managed.
Water-based systems generate nutrient
solution waste which must be managed
or cleaned and re-circulated.
Inert substrates need to be disposed of
at the end of their useful life, and this
Substrate materials differ in their physical
properties, providing different conditions for
root growth, transport of water, nutrients and
air, and consequently for crop yield.
Substrates with low water-holding capacity
need frequent watering. The acidity/alkalinity,
salt content and other characteristics of the
chosen substrate materials need to suit the

requirements of specific crops. For example,
strawberries grow very successfully on peat,
while some flowers and vegetables grow successfully on coconut fibre. The PBG Research
Station for Floriculture and Glasshouse
Vegetables in the Netherlands has published
a handbook on the physical and chemical
characteristics of a variety of substrate materials and suitable crops (Kipp et al 1999, 2000).
Rice hulls (waste from grain milling).
In general, desirable characteristics include
low weight, high water-holding capacity,
medium porosity and low cation exchange
capacity. A low carbon:nitrogen decomposition rate is desirable for hydroponic production. See Table 4.7.1 for information on the
characteristics of various substrate materials.
For detailed technical information on the
characteristics of a range of substrate materials refer to Kipp et al (1999, 2000).
Mushroom industry waste.
Substrate materials can be divided into two
broad types:
Organic substrates
Organic substrates are made from agricultural
products or dead organic matter. Many are
biologically active and have a high carbon:
nitrogen ratio, which means they are broken
down during the growing season by microorganisms, changing texture, pH and nutrients.
Organic substrates are not suited for hydroponic systems, but they are very effective for
crop production when used like potting mixes
in bags, pots, trenches or other containers.
The biologically active nature of organic substrates helps to provide a buffer if pathogens
are accidentally introduced into the system.
Some organic substrates strongly suppress
pathogens. For others, biological controls can
be added to give pest-suppressive properties.
Sources of organic substrate materials include
the following:
Coconut plant fibres or coir.
Composted plant residues or agricultural
waste.
Bagasse or sugarcane waste.
Peat and past substitutes.
Reed fibres.
Pine bark, sawdust and other waste
from the forest industry.
Straw bales.
Some of these materials must be mixed with
others to achieve successful substrate textures
and characteristics. Bagasse, for example, has
low porosity and high water-holding capacity,
which would lead to poor aeration for plant
roots if used alone . Sawdust also has a high
water-holding capacity that can lead to poor
aeration. Rice hulls, in contrast, have low
water-holding capacity and high pore space,
so plants would be vulnerable to water stress
if rice hulls were used alone (Johnson undated).
Each of these materials, however, can be useful
as one component of a substrate mixture.
Certain materials need to be treated before
use. Coconut, for example, sometimes has a
high salt content which makes it unsuitable for
strawberries unless it is washed before use.
Inert substrates
Inert substrates are made from materials such
as rocks or polyurethane. They do not have
the ability to suppress the spread of
pathogens introduced accidentally, so they
demand a high degree of sanitation and
hygiene. Some growers now add biological
controls such as Trichoderma (see Section 4.2)
to inert substrates to give them pest-suppressive properties. Inert substrates normally
require a high degree of water/nutrient management, because the plant gets all its nutrients from the delivered nutrient solution.
When selecting materials, weight is a consideration because heavy materials like gravel or
sand are more difficult for growers to move
around. Lightweight materials, such as pumice
or vermiculite, can be moved more readily.

In practice, substrates are used with a wide
variety of irrigation systems, from simple
punctured hoses to fully computerised, recirculated systems. Substrate systems can be
divided into two broad groupings listed
below. (See Table 4.7.2 for a comparison.)
Potting mixes

form of container, such as bags, buckets,
pots, lined beds (with wood, concrete or
brick sides), lined trenches in the soil, plastic
sleeves, hand-made tubes laid along the
greenhouse floor, or other simple devices. To
stop soil pests from migrating into the substrate, a barrier or space is needed to separate the drainage holes of the container from
the soil below. Examples of barriers include a
plastic sheet or thick layer of drainage gravel.
As with soil in pots or bags, water is applied
to the top surface of the substrates or via irrigation pipes or sprinklers. Any excess water
drains from the base of the containers and is
not re-circulated.
Some but not all of these systems require a
high capital investment and substantial knowhow. They can give high yields with low risk,
provided that suitable substrate materials are
used. Their use is increasingly common in
greenhouses and tunnels around the world.
They are also used in open fields in a few
cases.

Water-based and hydroponic systems
Hydroponic means “water working,” and
in these systems water is the principal
constituent. Substrates such as rock wool or
polyurethane foam provide support for the
plants, retaining nutrients and water.
Hygiene, water circulation and nutrient levels
are critical parts of the system and need to be
carefully controlled.
Hydroponic systems generally require significant capital investment, infrastructure and a
high degree of know-how and management.
The Nutrient Flow Technique (NFT) is one type
of hydroponic system in which a shallow
depth of nutrient solution is recirculated by
pump, through a series of narrow channels
where the plants sit. Water-based systems
can produce very high yields but have a high
risk of failure if not properly managed. They
are common in northern Europe and Canada,
and are used increasingly in many other
countries.
It is important to keep substrate systems free
from contamination by pathogens. Accidental
introduction of pathogens can be avoided by
using the following techniques:
Good standards of hygiene, such as
cleaning equipment after use.
Use of pathogen-free plant materials.
Placing substrates in many separate containers (e.g. pots or bags) rather than
one continuous container, to prevent the
spread of pathogens if contamination
occurs.
Use of clean water (e.g. filtering water
prior to use).
After use, organic substrate materials can be
disposed of by spreading them on fields to
improve soil texture. Some organic and inert
substrates can be re-used after being cleaned
with steam or solarisation. Substrates can be
solarised in bags or flats covered with transparent plastic or in layers 7.5 to 22.5 cm
wide sandwiched between two sheets of
plastic (Elmore et al 1997). In sunny areas
(e.g., warmer parts of California) substrates
inside black plastic sleeves can reach 70°C,
achieving effective solarisation within a week.
Current uses
Substrates are extensively used in greenhouses and nursery operations in many countries
and to a limited extent for open-field production. They are used for numerous crops,
including tomatoes, strawberries, cut flowers,
melons, cucurbits, bananas, nursery-grown
vegetable transplants and tobacco seedlings
(MBTOC 1998). Table 4.7.3 provides examples of commercial uses.

Pests controlled
92
Clean substrates are normally free from soilborne pests such as nematodes, pathogens,
weeds and insects, thus avoiding the need to
control these pests. Control with clean substrates is generally comparable to control
achieved with MB. Some natural substrates
(e.g. composted pine bark) also have the ability to suppress certain pathogens, reducing
risks if pathogens are introduced accidentally
by irrigation water or plant material.
Yields from substrates are equal to, and frequently higher than production with MB (see
Table 4.7.4), particularly because substrates
give a longer cropping period and allow double cropping or multi-cropping (Benoit &
Ceustermans 1991, 1995; Nordic Council
1993; Gyldenkaerne et al 1997). In addition,
substrates allow more control of harvest time
(such as earlier harvests) to meet more profitable market windows. Yields are generally
similar for the different types of inert substrates. Yields from organic substrates can be
more variable if they are used in systems with
unsophisticated management.
Substrates can be adapted for all types of
horticultural crops. They are most appropriate
for greenhouses, seedbeds and nursery containers, but they are also used to a limited
extent for open field production. However,
different substrates with different physical
and chemical characteristics are required for
different types of crops and uses. Substrates
are very suitable for double cropping and
multi-cropping.
Substrates are used in virtually all climates,
from the arctic to the tropics. They are suitable for all types of soils, because the soil
itself becomes irrelevant.
Farm workers can normally handle substrates
safely because they are composed of nontoxic materials. However, if substrate materials form dusts or fine particles, normal
precautions should be taken to prevent exposure to the dust while the substrate is being
laid out or moved.
Substrates do not normally require special
safety precautions, so safety training and
safety equipment are generally not required.
However, substrates that form dusts require
safety equipment to protect the lungs and
respiratory system. In some cases protective
clothing is desirable when the substrates are
lifted at the end of the season.
Substrates do not pose safety risks to consumers of fruits and vegetables, provided that
the quality and composition of substrates are
controlled to ensure that potentially toxic or
phytotoxic contaminants are excluded from
the raw materials.
Phytotoxicity
Commercially available substrate materials are
not phytotoxic to crops. If farmers make their
own substrates from locally available materials, they must avoid raw materials that may
cause phytotoxicity problems.
Substrates sit on top of the soil and are separated from it, so they do not have a direct
effect on beneficial organisms in the soil. If
disease-suppressive substrates are spread on
fields after their useful life, however, they
contribute beneficial organisms to the soil.
Substrates are compatible with the use of
beneficial organisms, and many substrate systems benefit from the addition of biological
control agents.
Substrates are not ODS.
consumption
Substrates in themselves do not have globalwarming potential, but like MB they require
energy for extraction, manufacture and transport. Some preliminary energy balances have
been carried out to compare MB and some
types of substrates. Available information
indicates that rock wool and polyurethane
foam substrates consume much more energy
in their manufacture than pumice and peat.
Natural substrates composed of waste materials consume the least energy, although this
depends on the distance that the substance is
transported.
In general, the energy required for production
using substrates is less than MB when measured per kg of produce. Low-technology systems have minimal use of energy, while
high-tech systems such as heated glasshouses
can use substantial amounts of energy.
Nevertheless, in northern Europe, for example, greenhouses that use MB and soil normally use more energy for heating than
greenhouses that use substrates.
Substrates made from rock (e.g. mica, volcanic pumice) and peat are extracted from
the natural environment and can damage
natural habitats such as wetlands.To avoid
this problem, it is desirable to consider other
source materials for substrates.
Water consumption in substrate systems
depends largely on the design and management of the system. Tomatoes grown in border soil or substrate systems can use the
same amount of water (Gyldenkaerne et al
1997). The wastewater can easily lead to
water pollution, if it is allowed to leach into
watercourses. Where there is concern about
run-off, organic substrates are preferable to
inert ones because they retain more nutrient
solution (Hardgrave and Harrimann 1995).
Various systems, such as those that clean and
re-circulate water, reduce water consumption
and minimise any pollution.
After use, organic substrates can often be
disposed of by spreading them on fields,
helping to improve soil texture. Inert substrates normally create problems with solid
waste, although collection and recycling
schemes exist for certain substrates (e.g. rock
wool) in certain countries. Most inert substrates can be cleaned and re-used. For example, polyurethane foam is treated with steam
in portable lorry-mounted chambers in
Belgium and can be re-used for 10 to 15 years.
Substrates are normally highly acceptable to
consumers. Supermarkets often prefer crop
production on substrates, because the products are generally more consistent and uniform in quality.
Normally, substrates do not have to be
approved and registered in the same fashion
as pesticides. Some countries have codes of
practice for ensuring quality control of substrate materials. Such controls are highly
desirable to ensure that substrates perform
consistently and are free from pathogens,
weed seeds and undesirable contaminants.
Cost considerations
In the case of hyrdoponic and recirculated systems, initial capital costs are
generally high or very high, compared
to MB.
In Denmark, the payback period for a
capital-intensive system is normally two
to four years (Gyldenkærne et al 1997).
Material costs are normally more expensive than MB, except where cheap or
waste materials are used as substrates.
Labour costs may be slightly higher.
Overall, substrate systems are often
more profitable than systems using MB,
Ozone depleting potential
93
because they allow longer production
periods or multi-cropping. In the
Netherlands, substrate systems increased
farmers’ incomes by 10 to 20% on average over previous MB systems (MHSPE
1997). In Florida (USA), the cost of producing greenhouse hydroponic vegetables ranges from US$ 2 to 15 per square
foot, but the costs are offset by higher
production (up to 10 times higher than
field-grown produce) (Hochmuth 1999).

5 Control of Pests in
Commodities and Structures
MB has been in widespread use as a fumigant for stored grains and import/export
commodities for more than 50 years because
of its high toxicity to a wide range of pests,
good penetration of products and rapid
action. The commodities and structures that
are fumigated with MB can be divided into
three main groups (refer to Figure 1.1):
a) Durable products
Durables are commodities with low moisture
content that, in the absence of pest attack,
can be safely stored for long periods. They
include foods such as grains, pulses, nuts,
dried fruits, herbs, spices, dried medicinal
plants and beverage crops along with nonfoods such as tobacco and seeds for planting.
They also include logs, sawn timber, wood
products, cane and bamboo ware, craft products, museum artifacts, items of historical significance, packaging materials and wooden
pallets.
Many durable products are stored and traded
globally without the need for MB fumigation,
but MB is used in a number of situations for
controlling stored product pests and quarantine pests. Fumigations are carried out in storage and transport areas such as grain stores,
warehouses, docksides and harbours, making
use of enclosures such as fumigation sheets,
silos, freight containers, railway box cars, ship
holds, barges and, in some cases, fixed
chambers.
b) Perishable commodities
Perishables are fresh commodities that generally decay quickly unless they are stored in
conditions such as cool storage that prolong
their shelf-life. They include fresh fruit, fresh
vegetables, cut flowers and ornamental
plants. Many of these commodities are traded
internationally without the need for fumigation, but MB is required in a number of cases
for the control of quarantine pests.
Fumigations are carried out in fumigation
chambers or under fumigation sheets at
places such as specialised farms, packhouses,
ports and airports. MB fumigations are carried out either in the country of origin before
export or in the importing country if products
are found to contain quarantine pests.
c) Structures
Structures include entire buildings and portions of buildings such as food processing
facilities, flour mills, feed mills, storage facilities and warehouses. This group also includes
transport vehicles such as ship holds, aircraft
and freight containers.
MB is sometimes used for controlling stored
product pests, wood-destroying organisms,
rodents or quarantine pests in such structures, particularly when a rapid full-site treatment is needed.
Pests in durable commodities
Pest control for durable products is necessary
to prevent insects from eating or damaging
commodities with a resultant loss of product
or reduction in market value. In some cases, it
is only necessary to manage and suppress
pests to levels that do not cause significant
damage. In other cases, it is necessary to disinfest commodities to entirely eliminate pests
to meet commercial demands for products
that are pest-free or to meet official preshipment requirements. Disinfestation is also
Section 5: Control of Pests in Commodities and Structures
Types of commodities and
structures
97
required for officially controlled quarantine
pests to reduce the risk of introducing or
spreading pest species to geographical
regions where they are not established.
According to MBTOC, MB plays a relatively
small but significant role in the disinfestation
and protection of durables. This use adds up
to an estimated 13% of worldwide MB consumption or around 19% in developing countries, making durables the second largest use
of MB after soil fumigation.
98
MB’s rapid action and reliability have led to its
continued use as the treatment of choice in
several specialised situations:
Rapid disinfestation of bulk grain to
meet commercial, phytosanitary (plant
health) or quarantine requirements at
the point of import or export.
Quarantine treatments against specific
pests, particularly khapra beetle, the
house longhorn beetle and various
snails.

Disinfestation of stacks of bagged grain,
particularly in Africa, including food aid
at the point of import.
Protection and disinfestation of dried

nuts in storage and prior to sale.
Although the use of MB to control pests in
stored grains has largely been replaced by
other techniques in developed countries, the
practice is still widely used for this purpose in
a number of developing countries.
Most of the target pests of durables are
insects and, to a lesser extent, mites. Certain
commodities have other target pests, such as
fungi in unsawn timber and nematodes in
seeds for planting. MB is sometimes specified
as a quarantine treatment for ticks and snails
that occur as incidental contaminants of
durable foods or timber. Table 5.1 provides a
list of the principal pests of cereal grains and
similar durable commodities.
Pests in perishable commodities
Fresh fruit, fresh vegetables and cut flowers
can carry a wide range of pests, such as fruit
flies and mites, and many of these are the
subject of quarantine restrictions for
import/export commodities (Table 5.2). MB
treatments to kill pests in perishable commodities are estimated to account for about
9% of MB consumption worldwide
(MBTOC 1998).
Treatments for controlling quarantine pests
have to be approved by the quarantine
authorities of importing countries for individ-

ual commodity/pest combinations. This normally requires scientific data to demonstrate
that the treatment is virtually 100% effective
in killing the target quarantine pest, as well
as a process of bilateral negotiations.
Historically the process of gaining approval
for quarantine treatments for perishables has
been very slow, taking from 3 years to well
over 10 years. Pressure from companies and
governments to phase out QPS uses of MB is
likely to speed up the approval process in
some areas. Quarantine issues are discussed
in detail in the reports of MBTOC (1998) and
TEAP (1999).
Pests in structures
Pests that infest durable commodities often
become established in the fabric of buildings
or structures where food is stored. Wooddestroying insects can also infest the wooden
beams and wooden parts of buildings. Table
5.3 lists major pest groups that are the tar-
gets of MB fumigation in structures. MBTOC
estimates that these uses account for about
3% of MB use worldwide (MBTOC 1998).
Overview of alternatives
A wide variety of measures can be incorporated into an integrated system to disinfest
and protect commodities and structures from
damage by pests (MBTOC 1998). The following major techniques are described in
Section 6:
IPM and preventive measures.
Cold treatments and aeration.
Contact insecticides.
Controlled and modified atmospheres.
Heat treatments.

All techniques listed above can suppress
pests, but some can also be applied to provide disinfestation in certain commodities,
allowing them to meet commercial, preshipment and quarantine requirements for
pest-free products. Table 5.4 provides an
overview of the types of commodities and
structures for which alternative techniques
can be effective.
None of the techniques, however, can be used
for all of the applications for which MB is
used. Each alternative has different advantages and disadvantages and must be selected
for the appropriate commodity or structure
and circumstances. Section 6 covers the
advantages, limitations and suitability of
alternatives for different situations and
climates.
Commercially available alternatives
Many alternatives have been developed to
the commercial level. Some techniques are
used by a small number of enterprises or in a
few countries, while others, such as phosphine, have widespread adoption. Examples
of alternatives used for grain and other
stored products are given in Table 5.5, for

These examples are intended to illustrate the
diversity of techniques available, but it is
important to note that each technique is suitable for different and specific situations. For
example, a slow-acting nitrogen treatment is
not suitable for a situation where a rapid
treatment is required. Likewise, cold treatments cannot be used for cold-sensitive commodities that could be damaged by cold.

been identified. MBTOC recently reviewed
alternatives and failed to identify existing
alternatives for the following quarantine and
pre-shipment uses of MB for durable commodities and structures (MBTOC 1998, TEAP
1999):
Disinfestation of fresh walnuts for immediate sale.
Disinfestation of fresh chestnuts.
Disinfestation of oak logs with oak wilt
fungus.
Elimination of seed-borne nematodes in
alfalfa and some other seeds for
planting.
Control of organophosphate resistant
mites in traditional cheese stores.
Mills and food processing facilities where
IPM systems have not been implemented
successfully.
Some cases of aircraft disinfestation.
Worldwide, these uses are unlikely to exceed
50 tonnes of MB per year in total (MBTOC
1998).
For perishable commodities, MBTOC failed to
identify approved quarantine treatments to
replace MB in the following commodities and
situations:
Apples potentially infested with codling
moth and exported from New Zealand
and USA to Japan.
Stonefruit (peaches, plums, cherries,
apricots, nectarines) potentially infested
with codling moth and exported to
countries free from codling moth.
Grapes potentially infested with
Brevipalpis chilensis mites exported from
Chile to the USA.
Grape exports from USA to countries
that require MB fumigation.
Berryfruit (strawberry, raspberry, blueberry and blackberry) exports from countries
such as Australia, Brazil, Canada,
Colombia, Israel, New Zealand, South
Africa, USA and Zimbabwe.
Root crop exports (carrot, cassava, garlic,
ginger, onion, potato, sweet potato, taro
and yam) where infested with quarantine pests.
While viable alternatives are not available for
the above uses today, it should be noted that
MBTOC (1994, 1998) has identified many
potentially effective alternatives that will
require additional research and development
for application to these specific commodities
and pests.
Identifying suitable alternatives
The identification of a technique appropriate
for a specific situation can be complex,
because it requires consideration of a wide
range of technical, economic, market, regulatory, safety, environmental and organisational
factors (see also Section 2). The process may
be simplified by following the five steps outlined below:
2.
3.
4.
Develop a thorough understanding
of the pest problems by identifying the
pests and learning about their life
stages, habits, preferences and the factors that keep them from thriving.
Be clear about the market and regulatory requirements for pest control.
What degree of pest control is needed?
Will pest suppression suffice or is virtual
elimination of pests necessary? What
practices could be introduced to prevent
pest populations from building up and
to reduce the frequency of disinfestation
treatments?
List the techniques that would be
effective in controlling the pests in your
commodity/structure. Initially, focus solely on technical issues and be sure to
make a full list of all possible options.
You could start by making a list of all
pests that affect the commodity or structure. For each pest, identify all the remedial treatments and preventive practices
that would control each pest to a satisfactory level. Then use the list to identify
the different combinations of techniques
that could control the full range of pests
you will encounter. Annex 4 provides
template tables to guide you through
these steps.
Evaluate the suitability of each technical option for your situation. For
each option, list the technical requirements, advantages and disadvantages,
and consider the relevant issues, such as
staff requirements, logistics, equipment
and materials, costs, regulatory requirements and safety and environmental
issues. (Refer to Section 2 for a brief discussion of these issues.) You may find it
useful to summarise the information in a
table format, as shown in Annex 4.
Specific questions relating to your commodity
and situation can include the following:
Which pest species and life stages need
to be controlled?
What degree of pest control is required?
What are the habits and preferences of
these pests? Which factors favour or discourage their presence, stage development and reproduction? Where and
when is each pest species vulnerable?
Which procedures and treatments are
technically capable of controlling the
pests?
What steps can be taken to prevent the
entry of pests, prevent the build-up of
pest populations, and reduce the need
for disinfestation treatments?
How much time is available for carrying
out treatments?
Where time is a problem, can commodities be managed differently to allow
more time for treatments to be carried
out? For example, can treatments be
carried out at an earlier stage of storage
and handling, or while in transit?
Which treatments can the commodity or
structure safely withstand without damage or effects on commercial quality?
Would residues or other effects present
a problem for companies that purchase
the products?
Which treatments do pesticide safety
authorities already permit? Which treatments do not need to be registered?
What safety measures need to be taken
to protect staff, local communities and
the environment?
Which treatments and practices will
allow staff continuous access to commodities and working areas?
What facilities, equipment and staff skills
are currently available?
What changes in equipment, materials
and staff skills would be required by the
alternatives?
What changes in management and
working procedures would be
necessary?
1.
105
What activities or steps would have to
be carried out to introduce each alternative?
What are the capital and set-up costs,
operating costs, profitability and payback
period for each alternative system?
How can the alternatives be adapted
and improved to better suit local
circumstances?
106
5.
Develop a plan. Once you have chosen
the most promising techniques, identify
the main steps and activities that adop-
tion of the technique(s) will require. Try
to talk with specialists and suppliers to
find ways to adapt systems to your
needs, to make change feasible, to
improve efficacy and to reduce costs. For
assistance, refer to the information in
Sections 6.1 through 6.7, consult the
specialists and suppliers listed toward the
end of each Section and the reading
material listed in the corresponding section of Annex 7. See Annex 6 for an
alphabetical listing of supplier names
and contact information.
6.1 IPM and preventive
measures
In order to replace a particular use of MB, it is
often necessary to combine several different
alternatives in IPM or Integrated Commodity
Management (ICM). In most situations with
stored products and structures, it is possible
to avoid or minimise pest infestation so that
”clean up” with MB is not needed. This type
of pest management is not just a replacement for MB but often avoids the need for
MB or other remedial treatments.
The term IPM is used to describe diverse combinations of treatments and practices to control pests. Development of an IPM system
starts with the identification of existing and
potential pests and an understanding of the
causes of their presence, the factors that
allow them to thrive, and their vulnerabilities.
Prevention is a major component of IPM and
involves activities such as the removal of pest
refuges, regular cleaning of storage areas,
and use of physical barriers to prevent pests
from entering products. Products and structures are monitored regularly for insects, and
action is taken if an ”action threshold” is
exceeded. The threshold notion involves
determining the level of pest activity that can
be tolerated without significant product loss
or damage. Such a threshold is based on the
amount of economic damage that can be tolerated as well as the size and life stage of the
populations of pests — detailed informaiton
about IPM approaches for stored products
can be found in Subramanyam and Hagstrum
1996.
The components of an IPM system will vary
greatly from one situation to another,
because the system and practices are tailored
to a specific location. Some IPM systems
require constant maintenance in order to succeed, and occasional full-site or curative treatments may be required to supplement IPM
systems. An IPM system for grain stored in
bulk or bags, for example, may include cleaning, pest detection procedures, insecticide
sprays, stock rotation and control of the storage environment.
IPM requires knowledge about the interactions between stored products, the storage
environment and the insects associated with
the products. It requires significantly more
know-how than does MB use, and substantial
effort needs to be put into training technicians and commodity managers.
Pest management for durables and
structures
Three important components of pest management for stored products include prevention, monitoring and control (Mueller 1998).
a) Prevention
For an IPM programme to succeed, the
largest proportion of time and effort (about
75%) should go into the tasks of preventing
pests from entering storage areas and products, where possible, and preventing them
from thriving and accumulating. These aims
require changes in commodity management
practices, adaptations to the physical environment of storage areas, and the introduction
of measures to ensure high levels of
cleanliness. Typical prevention activities
Section 6: Alternative Techniques for Controlling Pests in Commodities and Structures
6
Alternative Techniques for
Controlling Pests in Commodities
and Structures
107
Changing farm practices, where possible, so that products are kept in clean
conditions as soon as they are harvested.
Using physical barriers (e.g., insect-proof
storage containers, insect screens on
windows and openings) to prevent
insects from entering structures or gaining access to products.
108
Removing articles and altering storage
areas to eliminate crevices and places
that could provide refuge for pests, both
inside and outside the storage facility.
Drawing up a work programme for frequent cleaning (including sweeping and
vacuuming) of all parts of the storage
premises, to assure that they are free
from food residues and debris that
attract insects and rodents.
Maintaining a 45-cm (18-inch) gap
between stored products and interior
walls, to assist cleaning.
Keeping outside areas clean of food
residues that might attract pests.
Cleaning all empty commodity receptacles before re-filling, so that no insects
remain.
Establishing procedures to verify that
new batches of products are free from
pests and only clean products are
brought into stores. Such procedures
would include inspecting incoming products and packaging materials for pests
and placing contaminated products into
separate holding areas until they have
been disinfested.
Keeping products cool and/or aerated,
where feasible.
Keeping moisture levels low.
b) Monitoring
About 20% of the time and effort of an IPM
system involves monitoring for pests and carrying out inspections to ensure that prevention practices are properly implemented.
Diligent monitoring allows for early action
when pests are found. Common activities
Using effectively designed insect and
rodent traps with correct pheromone or
bait for attracting target pests.
Having the correct number (density) and
placement of traps.
Inspecting batches visually.
Examining samples of incoming products
and stored batches of products.
Using records to identify old stock, since
pest outbreaks often start from pallets of
old products that have not been rotated
or monitored.
Maintaining records and rotating stock.
Checking moisture, temperature and
other conditions that favour or discourage pests.
Inspecting premises regularly to ensure
that cleaning has been done thoroughly.
c) Control
If prevention and monitoring are carried out
effectively,then less than 5% of time and
effort will go into treatments to eliminate
pest infestations. Curative treatments become
necessary if pest populations become established, often an indication that prevention
and monitoring have not been thorough.
In contrast to the approach outlined above,
enterprises generally put most effort into disinfestation treatments and put little effort
into prevention and monitoring. MBTOC
points out that many MB alternatives are not
direct replacements for MB; rather they are
measures designed to avoid the need for MB
(MBTOC 1998).
Preventive measures for perishable
commodities
For perishable commodities, some measures
can be introduced in the field and after harvest to avoid the need for MB fumigation or
other quarantine treatments. This is an

advantage, because MB and other treatments
can reduce the shelf life and market quality
of perishable commodities. Examples include:
a) Inspection and certification
In some circumstances, it is feasible to establish a system for inspecting and certifying that
products are free from target pests before they
are exported. For example, Japanese quarantine officials inspect cut flowers in the
Netherlands and Colombia prior to shipment;
this reduces the need for inspection and disinfestation treatments on arrival in Japan.
Inspection is labour intensive and needs to be
carried out by personnel who are well trained
and accepted as competent and independent
by the importing country. Inspection may
become simpler in the future with the
development of automatic equipment to scan
products and detect pests. For example,
chemical sensors may be designed to detect
or “smell” specific compounds emitted by
pests.
b) Pest-free zones
Some countries have certain geographic
regions that are free from quarantine pests of
concern, even though the pest is established
in other parts of the country (Shannon 1994).
Where regions can be proven and certified as
pest-free zones, products can be exported
from them without a quarantine treatment.
A substantial amount of scientific survey data
is required to demonstrate that an area is free
from the target pest. In addition, regulatory
measures are required to keep the area
pest-free, and on-going surveillance must
be carried out. Pest-free zones have been
established in a number of countries, including Australia, China, the Netherlands and
Chile. Further examples of approved pest-free
zones can be found in Table 6.1.1 and in
Riherd et al (1994).
c) Systems approach
For certain commodities and pests it is feasible to set up procedures on farms and after
harvest to ensure that many small steps eliminate quarantine pests. Examples of measures
Planting commodities that are not the
preferred host of the quarantine pest
(Armstrong 1994a).
Harvesting when the commodity is not
susceptible to attack by the pest.

Harvesting when the pest is not active.

The systems approach for achieving quarantine security has been described by Jang and
Moffitt (1994) and includes the following
steps:
Consistent and effective management
for reducing pest populations in farm
fields.
Preventing the commodity from becoming contaminated with pests after harvest and during shipping.
Culling in the pack house.
Monitoring, inspecting and certifying the
critical parts of the system.
The systems approach can achieve or even
exceed the level of quarantine security
required by an importing country (Moffitt
1990, Vail et al 1993). It depends heavily on
knowledge of the pest-host biology and life
cycles, well-trained staff and implementation
of effective management systems.
Among the cases of commercial application
(MBTOC 1997, MBTOC 1998), is the export
of avocados from Mexico to 19 Northeastern
states in the USA. Products protected in this
manner are certified free from avocado seed
weevil, avocado seed moth, avocado stem
weevil, fruit fly and other hitchhiker pests,
based on field surveys, trapping, field treatments, field sanitation, host resistance, postharvest safeguards, pack house inspection,
fruit culling, shipping only in winter, and
inspection on arrival in the importing country
(Firko 1995, Miller et al 1995). Other examples of the systems approach for quarantine
purposes include citrus exported from Florida
USA to Japan and apples exported from USA
to Brazil.

Combined treatments can be very useful in
replacing MB for perishable commodities,
because they allow several narrow-spectrum

used to prevent damage, pest multiplication
and reinvasion, and a high mortality of stored
product pests can be achieved if grain is kept
below 5°C for at least four months (MBTOC
1994). Ambient cold air — such as cool, dry
night air — is fed into the stored commodity
through an aeration system, typically consisting of ventilation ducts, fans and a control
system. Cooling can also be achieved by
transferring commodities from one bin to
another in cold weather, exposing them to
the cold air.
Cold storage extends shelf-life.
Some cold treatments provide
disinfestation.
Disadvantages
Relatively long treatment times (with
some exceptions).
Relatively expensive.
Consumes energy.
Not suitable for products that cannot
withstand cold temperatures.
Cold treatments can be used for stored products as part of an IPM system, and can also
be used for disinfestation to meet QPS
requirements. Below about 10°C insect reproduction ceases and the populations of most
pests of durable products slowly decline.
Temperatures of -15°C for a few days control
most pest species in durable commodities.
Temperatures around 0°C kill certain quarantine pests of perishable commodities, particularly fruit fly species.
Several cold treatment techniques may be
used:
Aeration
Aeration is used in many temperate regions
with the aim of cooling grain soon after harvest to a temperature low enough to prevent
the development of major insect species (typically less than 14°C). Aeration is typically
Aeration must be combined with other techniques to give control equivalent to repeated
fumigations with MB, but of itself can give
sufficient insect control to meet the requirements of some markets. Well-controlled aeration and cooling result in negligible grain
losses due to insect pests.
Refrigerated cooling
If cool, dry ambient air is not available for
aerating grain, it is feasible to use refrigeration units to chill and dehumidify incoming
air, even in humid sub-tropical environments.
Many grain silos in the Mediterranean and
sub-tropical regions use this technique
(MBTOC 1998). Other durable products can
be held at refrigeration temperatures (preferably less than 5°C) to delay the development
of pests.
Cold treatments
Cold storage at temperatures down to about
0°C is suitable for long-term protection of
certain types of durable products, such as
prunes, dried pears, nuts and beverage crops.
Commodities can be stored in cold stores and
other warehouse facilities equipped for refrigeration. Cold treatments in the range of -1 to
+2°C are important quarantine treatments for
certain perishable commodities, such as citrus
fruit, and a number of different treatment
schedules have been approved by quarantine
authorities. These vary with the type of fruit,
target pest and destination country. Table
6.2.3 provides examples of quarantine cold
treatment schedules. Cold treatments can
Freezer treatments
All common stored grain insect pests can be
controlled when grain is exposed for 2 weeks
to temperatures lower than -18°C (MBTOC
1998). Such freezer treatments are used for
the disinfestation of small batches of high
value grain, including special seed stocks and
organically grown rice. Exposure to -10°C for
about 11 hours disinfests dates, for example.
This treatment is particularly effective when
combined with a brief exposure to 2.8% oxygen or to low pressure, which causes insects
to leave the centre of the fruit and become
vulnerable to the cold (Donahaye et al 1991,
Donahaye et al 1992).
While freezer treatments are effective for certain types of durables, they are sometimes
only practicable for treating small quantities
in batches. Freezing cannot normally be used
for perishable commodities, because such
commodities have a high moisture content
and fragile cell walls that make them vulnerable to severe damage.
For quarantine purposes, freezer temperatures are typically required to eliminate pests
sufficiently in durable products. In the case of
perishable commodities, quarantine treatments are based on higher temperatures, typically -1°C to +2°C, although the exact
temperature and duration depends on the
susceptibility of the target pest and the commodity’s tolerance of cold.
Cold temperatures have to be carefully selected to kill target pests while avoiding damage
to products, particularly those of tropical origin, which are more sensitive to cold. In some
cases it is possible to prevent damage by
using two-stage treatments (Houck et al
1990a, Aung et al 1997).
Many commodities, such as grain, are poor
thermal conductors and provide pests with
some protection against the cold, so it is necessary to ensure that cold temperatures are
achieved within the commodities, not simply
in the air spaces between them. The required
treatment times vary greatly according to the
following factors:
Temperature.
Rate at which the commodity conducts
the cold.
Pest species and pest life stage.
A treatment period of between 12 and 24
days at about 0°C is generally required to disinfest perishable commodities of fruit flies,
while a 2-week treatment below -18°C is
required to disinfest grain of common pests.
On the other hand, some cold treatments are
considerably faster than this and faster than
MB fumigation. For example, a treatment to
disinfest dates requires 10.5 hours of exposure to -10°C or only 2.25 hours exposure at
-18°C (Donahaye et al 1991).
Where feasible, it is desirable to carry out
cold treatments as part of the normal cool
storage or handling of products. Cold treatments can sometimes be carried out in refrigerated shipping containers while products are
in transit to markets. One of the advantages
of cold treatments is that staff members have
continued access to commodities at all times.
This contrasts with MB fumigation, during
which staff cannot enter the commodity area
for safety reasons.
Current uses
Diverse types of cold treatments are used
commercially for a wide range of products in
both warm and cool climates (Table 6.2.1).
Cold treatments are used as part of IPM systems for grain in the Mediterranean region,
North America, Australia and other areas.
Cold treatments are also used where cold
storage warehouses are part of a storage system, for example for prunes in the USA and
France.

as museum objects, small quantities of seed
and high value grain products. Cold treatments are also used as quarantine treatments
for perishable commodities, such as citrus
and fruit from temperate climates.
Material inputs
For aeration: ducts, fans and control systems in storage structures.
Additional electrical services.
Refrigeration treatments require the use
of a cool store or cold storage warehouse, or require refrigeration equipment to be fitted to the storage or
shipping containers.

For ambient air aeration: cool or cold
ambient air during day or night, with
low or moderate humidity.
Where disinfestation is required, sufficient time during storage or transportation to allow a treatment to kill all target
pests at all life stages.
Pests controlled
Cool temperatures provide pest management,
while freezing temperatures are normally necessary for disinfestation. If grain is held at less
than 5°C for several months, most of the
immature stages of stored product pests die
off, although some adult pests may survive.
Cool temperatures (below about 10-15°C)
generally do not kill insects but stop their
feeding and reproduction, with a resulting
slow decline of most pest populations in
durable products. Temperatures of -15°C for
a few days control most pests (Chauvin and
Vannier 1991, Fields 1992).
All stages of Sitophilus granarius,
Callosobruchus rodesianus, Ephestia cautella
and Ephestia kuehniella are killed at -18°C for
In general eggs are more cold-sensitive, while
adults and larvae are often more tolerant of
cold. Species of tropical origin, such as
Sitophilus oryzae, Sitophilus zeamais,
Tenebroides mauritanicus and Lasioderma serricorne, tend to be cold sensitive, although
some important pests including Cryptolestes
spp., bruchids, mites and some Lepidoptera
species are very tolerant of cold temperatures
(Armitage 1987, Lasseran and Fleurat-Lessard
1991, Fields 1992). The diapausing moth
larva is highly resistant to cold, requiring
more than 14 days at -10°C or 1 day at
-15°C; the adult rusty grain beetle, on the
other hand, requires 8 weeks at a grain
temperature of -5°C, 6 weeks at a grain
temperature of -10°C, or 2 weeks at a grain
temperature of -15°C (Banks and Fields
1995). Some species of insects have the ability to acclimatise to cold and may become tolerant to temperatures that would normally be
lethal. Rapid cooling may be necessary to prevent such adaptation.
Product quality
Cool and cold treatments for stored grain
give grain quality that is the same as or better
than MB fumigation. Cool storage maintains
the quality and extends the shelf life of perishable products. Cold temperatures down to
about 0°C can be tolerated by a number of
perishable commodities, but in some cases a
pre-conditioning treatment, such as exposure
to 15°C, is necessary to prevent damage to
products.

Cold treatments do not involve the use of
toxic fumigants. Exposure to cold temperatures can present a health hazard for staff

There is no regulatory approval required for

country. (See Table 6.2.3 for examples).
Safety training is necessary for working in

None.
Ozone depletion
Many refrigeration units and freezers contain
ODS, so it is highly desirable to select equipment that does not, whenever possible.
consumption
For aeration, moderate amounts of energy
are consumed in the operation of fans. The
operation of refrigeration units and freezers
requires substantially more energy, and some
refrigeration equipment contains HFCs, which
are greenhouse gases (GHG). The selection of
GHG-free equipment with reasonable energyefficiency ratings can help to mitigate these
undesirable impacts. In some situations, it
may be possible to use local renewable
sources of energy.
If refrigeration equipment is not properly
maintained, refrigerants may leak out. In general the equipment has a very long life, and
theoretically many of the component parts
could be re-used.
Cold treatments are highly acceptable to

can be less than the cost of one year’s
application of MB. Bulk grain aeration
needs ductwork similar to MB fumigation, as well as a control system and fans.
Labour costs of aeration are probably
cheaper than MB, because automatic
controls are normally used.
For cool and cold treatments, the capital
costs are higher than MB, while labour
costs are similar.
The cost of cold treatments for durables
may be too high in regions with high
ambient temperatures, although cold
treatments for perishable commodities
can be economic where products have
to be chilled in any case to extend
shelf life.

6.3 Contact insecticides
Advantages
Long-lasting protection against pests.
Require less skill than application of MB.
Gas-tight enclosures not needed.
Relatively quick application time.
Disadvantages
120
Cannot replace MB entirely; normally
need to be combined with other
practices.
Can be used only for products and uses
for which they are registered or officially
permitted.
Slow action against pests, except for
dichlorvos.
Poor penetration of commodities.
Insect populations can develop resistance
to insecticides.
Many insecticides are toxic to humans,
animals and the environment.
Residues in food.
Contact insecticide is a term that covers a
wide range of chemical products toxic to
pests. Contact insecticides act against insects
in different ways, depending on the nature of
the particular chemical. Most are directly toxic
to pests, but some work by disrupting normal
insect processes. As a group, they are effective in controlling a relatively wide range of
pests, but they act slowly and need to be
used with other treatments or practices.
For stored grain, insecticides can provide a
useful means of avoiding the circumstances in
which fumigation becomes necessary. Where
permitted, they can be applied directly to
grain, storage buildings, transport vehicles,
artifacts, wood products and non-edible perishable commodities. Contact insecticides are
not normally registered for use on processed
foods.
Application time for contact insecticides is relatively short. Unlike fumigants, they do not
readily penetrate bagged or bulk grain, but
they can provide persistent protection against
infestation, lasting from less than 1 month to
24 months, depending on factors such as the
active ingredient, pest species, temperature
and humidity (GTZ 1996). This persistence is
an advantage in products stored for long
periods but a disadvantage if significant
residues remain when products are sold.
After continued use, insects may develop
resistance to particular insecticides or groups
of insecticides, so resistance management
strategies are necessary. In a number of situations, resistance can be managed by using
different treatments in rotation.
Contact insecticides are toxic not only to target pests but also to humans, animals and the
environment (see Annex 3), so they are subject to a number of regulatory controls and
should be used only by trained personnel. As
with other pesticides, insecticides have to be
registered for specific commodities and purposes, and their use varies widely with the
country, market preference and local regulations. In part because they leave residues in
food, some countries have been moving away
from this method of pest control.
Commercial formulations contain one or
more active ingredients as well as carriers and
special additives. The active ingredients are
the chemicals that act against pests; additives
and carriers improve adhesion, act as synergists or otherwise affect performance. The
main groups of active ingredients are as follows:
Organophosphate (OP) compounds
OPs, such as chlorpyrifos methyl, dichlorvos,
fenitrothion, malathion and pirimiphos
methyl, are used in many countries. They can
be effective against many of the storage
Concern with the toxicity of OPs may lead to
additional restrictions in the USA and other
countries. Dichlorvos differs from other OPs in
its rapid action against pests and volatility on
grain. Where permitted, it can be sprayed
onto bulk grain during grain turning a few
days prior to export to disinfest a cargo. In
some cases it can replace MB directly.
Pyrethroids
Pyrethroids, such as permethrin, cypermethrin, cyhalothrin and deltamethrin, are
chemicals based on the active ingredient of
pyrethrum. They are particularly effective
against bostrichid and dermestid beetles.
Some pyrethroids are very stable on grain and
their insecticidal activity may persist up to
two years (Snelson 1987). Their activity is
much less sensitive to temperature than that
of the OPs, but they are relatively expensive.
Most pyrethroids have low acute toxicity to
human beings.
Insect growth regulators (IGRs)
IGRs are not normally directly toxic to adult
pests but disrupt or interfere with the life
cycle or development of pests. Methoprene,
for example, is an analogue of a juvenile hormone. IGRs are considered to be more pestspecific than conventional contact
insecticides. One disadvantage is their long
persistence on foodstuffs, which may limit
their use to non-food products like stored
tobacco. IGRs tend to have low toxicity to
vertebrates (Menn et al 1989 in MBTOC
1994). They are relatively expensive.
Borates
Borates, such as boric acid and disodium
octaborate tetrahydrate, are inorganic compounds based on boron. When ingested by
pests, borates are effective against many
wood-destroying organisms and cockroaches.
They can be used as remedial treatments for
timbers, artifacts and wood in structures
(Lloyd et al 1997, Dickson 1996). They have
low toxicity to humans (Olkowski et al 1991).
Combined products
Combined products are also available in some
cases, providing a broader spectrum insecticide. Examples of OPs mixed with pyrethroids
include pirimiphos methyl with permethrin
and fenitrothion with cyfluthrin.
Insecticide products are available in a variety
of formulations, including:
Dusts – ready for use, for mixture with
commodities or surface treatments.
Emulsifiable concentrates – mixed
with water, mainly for surface treatments.
Wettable powders – mixed with water
for surface treatments.
Flowable concentrates – for surface
treatments.
Hot fogging concentrates – ready for
use or diluted with diesel or kerosene for
space treatments.
Application of insecticides varies as well. The
following are the primary methods of
application:
Admixture with commodities. Where
registered, insecticides can be applied
directly to grain during handling, e.g.
prior to bagging or on grain conveyors
and elevators.
Surface treatments. Insecticides can be
sprayed onto the surfaces of bagstacks,
walls and floors of empty structures,
transport vehicles, artifacts and timber.
In general, contact insecticides work bet-
pests, but most OPs have limited efficacy
against bostrichids. The stability of their
deposits on grain varies widely according to
the formulation and ambient conditions, particularly temperature and moisture. For
example, dichlorvos typically acts quickly and
degrades within a few days; malathion takes
several weeks to degrade; and pirimiphos
methyl degrades over many months
(MBTOC 1998).
121
ter on clean, smooth surfaces than they
do on dirty or rough ones; they persist
better on surfaces such as metal, wood
and polypropylene packaging than they
do on concrete, bricks, alkaline paint,
whitewash and jute bags (GTZ 1996).
Repeated surface spraying can lead to
the development of pest resistance.
122
Space treatments. Spaces of structures
can be treated by “fogging” or spraying
with small particles (often less than 50
microns in size). This treatment assists in
the control of flying pests but usually has
to be combined with other practices or
treatments, because it does not penetrate between stacked bags and fails to
control many hidden insects.
Aerosol formulations. Aerosol formulations of insecticides, such as dichlorvos
and permethrin, are used on cut flower
exports as a quarantine treatment in
limited cases (i.e., New Zealand and
Hawaii). They do not penetrate as well
as MB and require long exposures, from
3 to 16 hours (MBTOC 1998,
Hara 1994).
Chemical dips. Certain perishable commodities can be dipped in insecticide
solutions to control pests. Insecticide
dips can provide an effective treatment
for some cut flowers (Hara 1994).
Application techniques and safety precautions
for contact insecticides are described in publications such as GTZ (1996) and the instructions or manuals of product manufacturers.
Instructions should always be followed, and
products should only be used where they are
registered.

Current uses
A variety of contact insecticides are in commercial use. (See Table 6.3.2.) OPs, for example, are used on stored grain and storage
structures. Insecticides are used in food production plants in many countries. In some
cases they have been approved as quarantine
treatments; Japan, for example, has approved
a combination treatment where logs are
immersed in water and an insecticide mixture
is applied to the exposed surface (MBTOC
1998). Insecticide dips provide a common
post-harvest treatment for cut flowers (Hara
1994). However, the use of insecticides is
restricted to the products and countries
where they are registered.
Botanical insecticides derived from
plants, e.g., azadirachtin.
Additional types of IGRs (MBTOC 1994).
Material inputs
Pesticide product.
Application equipment appropriate for
the product, e.g., dusters, sprayers, fogging machines.
Safety equipment, such as protective
overalls, face shield or respirator, goggles, gloves and boots.
Personnel monitoring devices for safety.
Appropriate temperature and moisture
range for the formulation.
Products that are registered for the specific commodity or use.
Pests controlled
Insecticides are effective against selected
groups of stored product pests. Where registered, some can contribute to an IPM programme for pest suppression. Over longer
periods some can achieve disinfestation when
the immature pests in the product develop
into adults and are killed by the insecticide.

Organophosphate compounds can be
effective against a wide range of stored
product pests although higher doses are
necessary for certain pest groups such as
bostrichids. Dichlorvos acts rapidly.
Pyrethroids are effective against
bostrichid and dermestid beetles at a
much lower dosage than that required
for most other insect pests (MBTOC
1998, Snelson 1987).
124
IGRs can be pest-specific, but methoprene is effective against many stored
product pests including Lasioderma serricorne, Ephestia cautella, Oryzaephilus
surinamensis, Plodia interpunctella,
Rhyzopertha dominica and Trogoderma
granarium. It is not very effective against
Sitophilus spp. (Mkhize 1986, Snelson
1987).
Borates are effective against many
wood-destroying organisms (Carr 1959,
Barnes et al 1989, Dickinson and
Murphy 1989, Drysdale 1994, Nunes
1997, Manser and Lanz 1998). Higher
application rates are required for controlling termites (Lloyd et al 1998). Boric
acid dusts control cockroaches in 5 to10
days, as well as silverfish, carpet beetle
and certain other insects (Olkowski et
al 1991).
Product quality
Insecticide residues remaining in food products can reduce the market value in some
countries. Purchasers increasingly demand
commodities with negligible residues.
Suitable commodities and uses
Insecticides can be used on a wide range of
durable products, artifacts and structures.
Some formulations are only suitable for nonfood products. The approved uses of
insecticides vary greatly from one country to
the next, but regulatory authorities and
product labels should provide the relevant
information.
Insecticides are effective in most climates,
although the rate at which they degrade normally increases with temperature and moisture. They can be used in bulk bins, silos,
bags, stacks or structures, provided they can
be applied at an appropriate stage, such as
when grain is being moved.
Pesticides, designed to kill living organisms,
are by definition toxic substances. Most are
acutely toxic, while some also pose chronic
health risks (see pesticide data sheets in
Annex 3). The mixing and application of pesticides can pose health and safety risks to
applicators and staff. Empty containers and
improperly stored pesticides pose health risks
to local communities. Accumulated residues
in food can pose risks to consumers.
Handling of pesticides requires thorough safety training, safety equipment and appropriate
management and emergency procedures.
Product labels and safety instructions must be
followed.
Pesticides can leave undesirable residues in
products, water and other parts of the environment, particularly when applications are
repeated or where pesticide containers
are dumped.
Ozone depletion
None of the insecticides listed in this chapter
are known to be ODS.
consumption
These insecticides are not known to be greenhouse gases. Pesticide products require energy for their manufacture and distribution.
Some insecticides are derived from nonrenewable materials. Empty product containers can be a source of environmental
pollution and must be disposed of properly.
There is increasing concern about insecticide
use and residues. In general, consumers do
not like chemical treatments for food products, and supermarkets increasingly favour
residue-free foods.
Normally, insecticide products can only be
marketed, if the government authorities that
control pesticide registration have approved
them. In addition, food or health authorities
normally limit residues in food products.
Pesticide use is normally restricted to specific
products and applications. Most governments
also place restrictions on pesticide marketing,
labels, disposal and other aspects of pesticide
use.
Cost considerations
Insecticides are typically cheaper than MB,
although some of the new insecticide products are more expensive. The labour costs
associated with insecticides are often less
than those associated with MB, because they
require semi-skilled personnel rather than
skilled, certified personnel.

Advantages
Effectively controls a wide range of pests
including rodents.
Most methods pose relatively few safety
issues and normal work can continue
near treatment areas.
Nitrogen and carbon dioxide do not
leave undesirable residues in food.
Treatments can be carried out in-transit.
Can be tolerated by all durable
commodities.
Disadvantages
Treatments are normally slow, unless
combined with pressure or heat.
Most methods require good sealing.
Treatments do not kill fungal pests.
Because insects need oxygen to breathe and
survive, the percentage of oxygen in storage
containers can be reduced to levels at which
insects stop feeding and reproducing.
Normally air contains 21% oxygen, but if
oxygen levels are held below 1% for 2 to
3 weeks, most insect species are killed.
Rodents are killed when oxygen is reduced
to about 5%.
Controlled and modified atmospheres are
normally used as part of an IPM system for
managing stored product pests or for disinfestation. When used in well-sealed stores, a
single treatment gives a high level of protection against pests, because it controls pests
already in the commodity and the seal prevents re-invasion. It is suitable for bagged or
bulk grain and other durable commodities,
where it is feasible to arrange treatments of
more than two weeks (MBTOC 1998).
Oxygen is reduced passively in the case of
modified atmospheres and hermetic storage,
for example, by putting grain in sealed storage units so that insects slowly use up the
available oxygen and cease activity or die.
Alternatively, high levels of carbon dioxide or
nitrogen gas can be pumped into storage
containers or sealed sheets. The objective is
either to provide a level of carbon dioxide
toxic to insects (more than 60% in air) or to
reduce oxygen levels to less than 1%. Some
of these techniques are approved quarantine
treatments.
Treatment times for disinfestation can vary
from one to four weeks or up to eight weeks
in the case of artifacts and museum items,
depending on the insect species, its life stage,
temperature, commodity, and the method
used. Treatment times can be reduced substantially by adding pressure or heat. There
are several techniques for creating controlled
or modified atmospheres described below
(see Table 6.4.1 for summary).
Hermetic storage
Hermetic storage involves sealing products in
air-tight containers or enclosures with minimal air-space, so that insects slowly use up
the oxygen and many die (Annis and Banks
1993, Navarro et al 1984, Navarro et al 1993,
Varnava et al 1994). Once the unit has been
properly sealed, no further treatment is necessary, but the container must be checked
regularly to ensure it remains sealed and oxygen remains low. If the initial number of
insects is low and the container allows some
air leakage, however, pest populations may
survive indefinitely at very low levels. In
regions with significant temperature fluctuations, it is normally necessary to place a thick
layer of absorbent waste material, such as
maize cobs, on top of the grain so that
moulds do not produce mycotoxins in the
stored product. Hermetic storage is best done
6.4 Controlled and
modified
atmospheres

underground to reduce gas losses and keep
termperatures stable.
Hermetic storage systems can include:
Concrete platforms, bunkers and silos.
Portable cocoons.
Vacuum-sealed retail packs; sealed packs
(up to 50kg) containing sachet of oxygen-remover e.g. activated iron powder.
128
Nitrogen storage
Products are sealed in silos, containers or
inside well-sealed, gas-tight fumigation
sheets (Banks and Annis 1997, Cassells et al
1994, Hill 1997). Nitrogen, an inert gas, is
released into the container and pushes out
the air, with the aim of reducing oxygen levels to less than 1%. The gas must be topped
up from time to time to ensure oxygen levels
remain at the desired level. Nitrogen can be
supplied as a liquefied gas in cylinders from
commercial suppliers or made on site with
machines that remove oxygen from the air
and deliver a gas stream containing about
0.5% oxygen.
The treatment time for total disinfestation
depends heavily on the temperature of the
commodity but is typically one to four weeks.
Nitrogen storage is most effective when grain
is more than 20°C; at lower temperatures a
very long treatment time is needed for complete disinfestations if tolerant pests and
stages (such as Sitophilus pupae), are present
(Banks 1999). Nitrogen systems are effective
in reducing mould growth in higher storage
moistures (16 to 18% moisture), but anaerobic fermentation can take place at moisture
levels above this. A major export terminal in
Australia regularly treats bins of grain (2,000tonne capacity) with nitrogen, requiring
about 1m3 of nitrogen per tonne of grain
(Batchelor 1999).
Carbon dioxide storage or treatment
Effective treatments involve the release of carbon dioxide gas into well-sealed enclosures.
The gas displaces the air, with a typical initial
target atmosphere of more than 60% carbon
dioxide. In some cases, 80% carbon dioxide is
required (Banks et al 1991). Depending upon
the target pest, carbon dioxide concentration
should not fall below 40 or 50% in the first
10 days of treatment. At 25°C the total treatment period should be at least 15 days
(MBTOC 1998). Carbon dioxide works faster
than nitrogen because it has a direct toxic
effect on insects. The gas may have to be
topped up to keep carbon dioxide levels high.
The treatment time for disinfestation of grain
is typically two to three weeks. An in-transit
treatment is used for groundnuts shipped
from Australia.
Carbon dioxide and pressure
The combination of carbon dioxide and pressure (e.g., about 25 bar) can reduce the disinfestation time to less than 3 hours (Caliboso
et al 1994, Reichmuth and Wohlgemuth
1994, Prozell and Reichmuth 1991, Prozell et
al 1997). Treatments are typically conducted
in pressure-proof chambers with 20 mm steel
walls. The equipment has a high capital cost
but provides a very rapid quarantine treatment for high value durable products.
For all of the modified atmosphere treatments discussed above, the air-tightness of
stores or containers is an important factor for
effective control. Some existing structures can
be adapted. In the case of silo bins, the level
of sealing required for carbon dioxide or
nitrogen is greater than the level of sealing
typically used for MB fumigations in developing countries but similar to the level of sealing required for MB for safety reasons in a
number of developed countries.
Where systems provide a continuous flow of
gas, such as with a gas burner, the use of
somewhat less gas-tight enclosures is feasible
as well (Bell et al 1993, 1997a). Certain conditions, such as a large difference between
the grain and ambient air temperatures, can
cause moisture to migrate to the grain surface. Precautions to prevent or ameliorate
moisture migration are required for long-term
storage.
Improved application systems to reduce
cost and increase convenience.
A wide range of techniques has been developed for bulk or bagged commodities held in
different types of structures.
Material inputs
Carbon dioxide and nitrogen systems can
include:
Fixed bunkers and silos.
Portable cocoons.
For nitrogen treatments: gas-tight containers or fumigation sheets sealed with
gas-tight glues; supply of nitrogen gas in
cylinders, or equipment for extracting
nitrogen from air; monitoring device.
Fumigation under sealed sheets.
Retail packs.
In-transit treatments for export products.
Port-side treatments prior to export.
For carbon dioxide treatments: gas-tight
containers or fumigation sheets sealed
with gas-tight glues; source of carbon
dioxide; monitoring device.
Carbon dioxide, however, may be unsuitable
for concrete structures such as grain silos,
because the gas can cause corrosion in concrete (Taylor et al 1998).
For in-transit systems: as above, plus a
system for topping up the carbon dioxide concentration to replace losses from
leakage.
Hermetic store with vacuum pump for
rapid disinfestation (GrainPro).
For retail pack systems: barrier film plastics for making packs; adaptation of

For carbon dioxide treatments: a cheap

at least two weeks for carrying out treatment if long-term storage is required.
Pests controlled
Oxygen levels of less than 1% for at least 2
weeks (at > 20ºC) kill most stored product
insects, but the response of different species
to low oxygen levels varies widely. Many are
killed in a day or less at 25°C, but certain
stages of some tolerant pests (such as grain
weevils) may survive for 2 weeks or more.
Low temperatures protect insects against the
effect of low oxygen atmospheres, extending
the necessary treatment period. In general,
hermetic storage is suitable for pest suppression, while carbon dioxide and nitrogen can
be used successfully for pest suppression or
disinfestations. Specific examples of pest control include the following:
High carbon dioxide atmospheres (above
60% CO2) control most stored product
pests in 2 to 3 weeks at 25 to 30°C. As
an extreme case, Trogoderma granarium
in diapause stage requires exposures
longer than 17 days (at 30°C or less)
(Spratt et al 1985).
Carbon dioxide concentrations of 40 80% (depending on the species) provide
disinfestation in warehouses and silos
for a number of stored grain pests.
Necessary exposure periods vary from
5 to 35 days depending on the pest
species and temperature (Table 6.4.2)
(Soma et al 1995, Kishino et al 1996,
Kawakami 1999).
Humidified nitrogen in gas-tight enclosures can control all stages of museum
insect pests, if oxygen levels are less than
1% for up to 30 days (Strang 1996).
Exposure to carbon dioxide and pressure
of 30 kg/cm2 kills all insects including
immature stages (Caliboso et al 1994,
Reichmuth and Wohlgemuth 1994).
Controlled atmospheres can control
some pest species in perishables, such as
thrips, aphids and beetles (Anon 1993b,
Kader 1985, 1994).
In general, hermetic storage is suitable for
pest management, while carbon dioxide and
nitrogen can be used for both disinfestation
and pest management. Table 6.4.2 provides
examples of carbon dioxide disinfestation
schedules developed in Japan for major pests
of stored grain. Additional data on exposure

Current uses
Controlled atmospheres have been used for
disinfesting some dried fruits and beverage
crops for many years. Carbon dioxide treatment is used on a large scale in Indonesia for
long-term storage of bagged milled rice
stocks (Nataredja and Hodges 1990,
Suprakarn et al 1990). Hermetic storage, carbon dioxide and nitrogen treatments are used
commercially for diverse products (Table
6.4.3). Hermetic systems are used for storing
grains for periods of three months to several
years in Cyprus (Varnava and Mouskos 1996,
Batchelor 1999). Various hermetic systems

Ethiopia, Brazil and USA.
Product quality
If the correct concentration, temperature and
duration are chosen, product quality is not
diminished by the use of controlled atmospheres. On the contrary, the quality of rice
stored for long periods has been found to be
significantly better using carbon dioxide
rather than MB, probably because repeated
fumigations with MB reduce grain quality and
produce bromide residues. Unlike MB, controlled atmospheres do not affect the viability
of dry grains such as malting barley.
Suitable commodities and uses
Hermetic storage and modified atmospheres
are suitable for stored durable products.
Controlled atmospheres are suitable for pest
management and disinfestation of grains,
nuts, dried fruits, beverage crops, herbs,
spices, other durable commodities, artifacts
and museum items where time allows.
Pests
Granary weevil
131
Structures may be treated only if they can be
well sealed and closed for several weeks. Intransit controlled atmospheres and refrigeration can be used for perishable commodities
to reduce the need for quarantine treatments
on arrival in the importing country (Gay
1995, EPA 1997).
132
Carbon dioxide and nitrogen can be used in
temperate to tropical climates. Hermetic storage can be used in a wide variety of climates
provided that one of two conditions is met:
Either the grain is initially sufficiently infested
to assure that insects in the storage area use
up all the available oxygen or the moisture
content is in the range of 13 to 18%.
Precautions against moisture migration are
needed in climates where temperatures
fluctuate.
Hermetic storage does not involve the use of
toxic substances and poses no health risk
(except those normally found at any grain
storage area). Nitrogen is inert and not toxic
in itself, while carbon dioxide is toxic at higher concentrations. Controlled atmosphere
silos and containers lack sufficient oxygen for
humans to breathe. There is no risk of flammability with controlled atmospheres.
Hermetic storage does not require special
safety precautions, but precautions and training are required for use of nitrogen and carbon dioxide gas.
Nitrogen and carbon dioxide do not leave any
undesirable residues in food products. For
hermetic storage and situations where moisture migration may occur, suitable steps must
be taken to prevent mould affecting food
products.
Ozone depletion
Carbon dioxide and nitrogen are not ODS.
consumption
Nitrogen is not a greenhouse gas; but carbon
dioxide is. The impact of using carbon dioxide
may be mitigated to some extent by using
gas captured from local industries, such as
smelters and distilleries. Nitrogen treatments
require energy for generating the nitrogen
gas and for transporting cylinders (if the gas
is not extracted from air on-site). Carbon
dioxide requires energy for the generation or
capture of gas and transportation of cylinders. Hermetic storage does not consume
energy.
Controlled and modified atmospheres do not
normally generate waste products. Gas cylinders are generally re-used.
These treatments are regarded as non-chemical by consumers and are very acceptable to
purchasing companies.
Regulatory approval is not normally required
for hermetic storage. It may be required for
nitrogen and carbon dioxide treatments.
Cost considerations
For hermetic storage the initial capital
costs may be higher than one year’s
application of MB, while the labour and
operating costs are similar. In Cyprus, for
example, the total capital and operating
costs for a hermetic storage platform
system for 4,000 tonnes of grain is
about $4,500 for 1-year storage, $6,500
for 2 years storage and $8,400 for 3
years storage. This works out at about
$1.12 per tonne/year for grain stored for
1 year, and $0.80 per tonne/year for
grain stored for 2 years. (Batchelor
1999).
Can the store be made adequately
gas-tight?
Converting existing grain bins for nitrogen treatments involves a small capital
outlay. The operating cost depends primarily on the source of nitrogen gas.
Licensed fumigators and expensive safety
measures are not needed. A typical
3-week nitrogen treatment, using gas
supplied in cylinders, in Newcastle
Australia, for example, costs about
$0.39 per tonne of grain for materials
and labour. This compares with about
$0.35 per tonne for one MB treatment
(Batchelor 1999).
Can the commodity be treated while
in storage or does it need a special,
rapid treatment?
In general, nitrogen and carbon dioxide
treatments have capital costs lower than
MB, while operating costs may be similar, cheaper or more expensive, depending mainly on the source of the gas.
Finding a cheap source of gas can
reduce the cost substantially.
What changes need to be made to the
commodity management system?

Which pests need to be controlled?
What degree of control is necessary?
Would in-transit treatments or retail
packing be feasible and useful?
Is a cheap source of nitrogen or carbon
dioxide available locally?
Do temperature and commodity moisture affect the treatment choices?
Availability
Materials and equipment are widely available.

For storage periods of about one year or
longer, carbon dioxide and nitrogen are
often cheaper than MB.
Can logistical changes accommodate a
longer treatment period?

Heat can be used to manage or kill a wide
range of pests by inducing dehydration
and/or coagulating proteins and destroying
enzymes in organisms. Stored product pest
insects, for example, can be eradicated by
exposing them to temperatures of about
50°C. In general, commodities are heated to
temperatures ranging from 43 to 100°C, with
treatment times varying from one minute to
several days depending on the commodity,
pest and situation (see Tables 6.5.2).
During treatments, the temperature needs to
be monitored and achieved within the commodity itself, not simply in the air spaces.
Both the temperature and time need to be
controlled to kill the target pests yet avoid
damage to products from excessive heat, loss
of moisture or other changes due to heat.
The speed of treatment is generally determined by the rate at which heat penetrates
thick objects or commodity bulks, not by the
intrinsic speed at which heat kills insects.
The heat for treatments is normally generated
using conventional means such as oil, electricity or gas, although in some situations it is
feasible to use waste heat from other
processes. Numerous techniques are available
for delivering heat to durable commodities,
including hot air, fluid beds and kiln drying.
Steam treatments are specialised and suitable
only for durable items that can sustain high
humidity, such as dunnage, logs and some
types of wood. In the case of perishable commodities, hot water dips, vapour heat and
hot forced air techniques are in use. The
many diverse techniques can be divided into
the following broad groups:
Heated air
Air heated to a temperature of approximately
90°C is used to heat grain briefly to above
65°C. In the case of cereal grain processing
plants, the typical target temperature is 50 to
55°C for 20 to 30 hours for controlling
insects (Dowdy 1997). Heat applied in the
process of kiln drying disinfests sawn timber
and actually adds value to it. Convection
heaters or existing air ducts applying temperatures above 50°C for 20 to 30 hours are
used in some structures for controlling most
pests except cockroaches (Heaps 1998,
MBTOC 1998). Target temperatures must be
achieved in places where insects may be hidden, such as ducts, voids and pipe work.
Structural heat treatments are normally combined with IPM and applied several times a
year.
Fluid bed system
High-speed “fluid bed” systems for treating
bulk grain have been built and developed to
commercial prototype stage and successfully
handle up to 150 tonnes of grain per hour
(Sutherland et al 1987, Evans et al 1983,
6.5 Heat treatments
135
Thorpe et al 1984, Fleurat-Lessard 1985).
Typical temperatures are 65°C within the
commodity for about one minute. Installation
of large-scale treatment facilities, however, is
likely to be capital intensive. There are currently no heat installations of the size
required to meet the typical handling speeds
of large modern grain terminals, which often
handle 500 tonnes/hour or more on one belt.
Heat treatments with controlled
humidity
136
Artifacts and durable commodities normally
lose moisture during heating, but monitoring
and maintaining the moisture content of
items at the same level throughout the heating and cooling process can prevent this.
Artifacts and durable commodities can be
treated in chambers or other containers, or
the treatment may be applied as a space or
structural treatment. This process is more
expensive than heat alone but is very suitable
for historical objects and other delicate
artifacts that would normally be damaged
by heat.
For certain perishable commodities, such as
grapefruit, papaya and mango, high temperature forced air (HTFA) treatments have been
approved for quarantine. After loading commodities into a chamber, humidified air (typically 40 to 80% relative humidity) at 40 to
50°C is forced over fruit surfaces to raise the
internal temperature. The temperature and
relative humidity are controlled precisely to
prevent condensation inside the treatment
area and on commodities, protecting fruit
from desiccation and scalding (Gaffney and
Armstrong 1990, Sharp et al 1991).
Certain perishable commodities are given
vapour heat treatments that are broadly similar to HTFA, except that the relative humidity
is kept above 80%. Information on HTFA and
vapour heat treatments can be found in the
Textbook of Vapour Heat Disinfestation of
Japan (Anon. 1996), UDSA-APHIS (1998),
Armstrong (1994), Hallman and Armstrong
(1994), Sharp (1994) and Williamson and
Winkelman (1994).
Hot water immersion
Water is inherently more effective than humid
air as a heat transfer medium, and provides a
uniform temperature profile if properly circulated through the load of commodities
(Couey 1989). Hot water dips can be used to
control fungi as well as insects and snails in
wood and timber (MBTOC 1998). Depending
on the pest and commodity, quarantine treatments for specific perishables may be accomplished with submersion in hot baths, often
at temperatures between 43 and 47°C for
periods from 35 to 90 minutes (MBTOC
1998, Hara et al 1994). Such treatment provides the additional benefit of control of
post-harvest microbial diseases, such as
anthracnose and stem end rot (Couey 1989,
McGuire 1991).
In-transit steaming
In the USA, a method of in-transit steam
heating has been developed for bulk timber
and wood chips, allowing large cargoes (up
to 35,000 m3) to be treated hold by hold.
Low-pressure steam and/or hot water at 65
to 90°C is provided by a boiler, heating the
centre of the timber to at least 56°C for 30
minutes or more (Seidner 1997).
Combination treatments
Heat can be successfully combined with other
treatments, such as controlled atmospheres
and phosphine. Heat often acts as a synergist, increasing the diffusion and distribution
of gases and their powers of penetration; it
reduces the physical sorption of gases and
increases the toxicity or level of stress to target pests (Mueller 1998).
To avoid damage by heat, some durable
products need to be rapidly cooled to room
temperature after treatment. Delicate
artifacts and antiques can withstand heat
if their internal humidity is monitored and
maintained at the same level throughout the
Because they are susceptible to heat damage,
perishable commodities require heat treatments specially tailored for each variety.
Perishables that can tolerate certain heat
treatments for quarantine include tomato,
pepper, aubergine (eggplant), melon,
cucumber, papaya, some citrus fruits, litchi,
mango and cut flowers (Paull and Armstrong
1994).
nectarines, avocados or leafy vegetables
(MBTOC 1994, Couey 1989).
Current uses
Heat treatments were once widely used in
warm climates for disinfestation of commodities, such as grain in Australia and cotton and
cotton seed in Egypt, with large tonnages
being treated (Banks 1999). In some countries
heat has been routinely used to control
wood-boring pests in wooden buildings for
many years. Heat is also used commercially
for some wood products (Table 6.5.1). Heat
treatments are increasingly being adopted as
part of IPM systems for food processing facilities and mills in Canada. More than 75 commercial heat facilities have been built for
quarantine treatments for perishable commodities in Mexico and other countries of
Latin America (EPA 1996).
Computer-controlled heating techniques
allow greater control and shorter treatment
periods. Treatment times can also be reduced
with engineering improvements that move
hot air faster and more uniformly through the
commodity (Paull and Armstrong 1994). The
gradual heating of perishables is generally
preferable to rapid heating, and a pretreatment may increase the commodity’s
tolerance. Heat is unsuitable for highly
perishable products, such as asparagus,
Other sources of heat, such as
microwaves, radio frequency heating,
dielectric heating and infrared.

treatment. Some structures cannot tolerate
the stresses caused by the rapid change in
temperature and the differential expansion of
structural components such as concrete and
steel. Sensitive electrical equipment and other
heat-sensitive items must be temporarily
removed from structures or modified to
avoid damage. Some types of grease are liquefied by heat and have to be re-applied
after a treatment.

Lethal temperatures for insects and fungal
pests of perishable commodities can be
found in Jang (1986), Yokoyama et al (1987,
1991) and Moss and Jang (1991). Insect mortality due to heat varies according to factors
such as the species, insect stage, insect age,
availability of oxygen, pH, previous temperatures, and general energy status of the insect
(Moss and Jang 1991).
Heat treatments can be used for pest suppression and disinfestation purposes. There
are a number of heat treatments approved by
quarantine authorities for particular products,
and examples of these are listed in Table
6.5.3 and Table 6.5.4. Heat is effective in
replacing MB for some quarantine disinfestations targeted at Trogoderma granarium, an
important quarantine pest of grain (MBTOC
1998). Heat is one of the few treatments that
is effective at disinfesting bulk grain from live
snails (Cassells et al 1994).
Pests controlled
All stages of stored product pest insects can
be eradicated in less than one minute if
they are exposed to a temperature of 65°C.
Temperatures above 47°C for longer exposures are also lethal for many stored product
pests (Barks & Fields 1998). Tables 6.5.2 show
the temperatures and exposure times necessary to kill pests in certain commodities.
Further examples can be found in Forbes and
Ebling, Banks & Fields (1998).
Product quality
Depending on the temperature, the quality of
some grains may be affected by heat, thus
limiting the application to grains that will be
processed. Under good process control there
is no damage to the end-use qualities of cereals, such as bread-making wheat or rice, and
malting quality of barley (Fleurat-Lessard
1985, Sutherland et al 1987). However, the

margin of error is small and slight excesses in
treatment can adversely affect the product.
High temperatures lead to detrimental colour
changes or rancidity in many dried fruit
and nuts.
140
If humidity is carefully controlled throughout
the treatment, heat damage from moisture
loss can be avoided, even in many delicate
museum objects. Heat damage and protection measures for perishable commodities are
outlined in Paull and Armstrong (1994), Sharp
and Hallman (1994) and Lay-Yee (1994). Heat
treatments can also have beneficial effects on
quality, such as reducing susceptibility to chilling injury in persimmons or increasing firmness in apples and pears (Lay-Yee 1994,
Neven and Drake 1998).
Heat treatments at moderate temperatures
are suitable for durable products, artifacts
and structures that can withstand heat without damage to their market quality. The
range of suitable products can be extended
substantially if heat is combined with controlled humidity, because this prevents or
reduces heat damage in many situations.
Heat is not suitable for highly perishable
products, such as asparagus, nectarines, avocados or leafy vegetables (Couey 1989) or for
seeds that will be germinated (GTZ 1996).
Heat treatments do not leave undesirable
residues in treated products.
Ozone depletion
Heat treatments do not use ODS.
consumption
Heat treatments use energy for heat generation. The problem of carbon dioxide emissions from fossil fuels can be addressed by
using renewable sources of energy or local
sources of waste heat, where possible. A
Danish project has recently improved the
energy efficiency of heat treatments for
wood-boring beetles, reducing energy consumption by up to 50% (Host Rasmussen
1998). Computer-control of heat treatments
often allows improved energy efficiency.
Surplus heat is the main waste product.
Where possible, it is desirable to capture this
for other constructive purposes.
Properly conducted heat treatments are very
acceptable to supermarkets and purchasing
companies. They are highly acceptable to
consumers, because they are traditional, nonchemical treatments.
Heat treatments are not limited by climate
and can be conducted in a wide range of
regions from temperate to tropical.
Heat treatments do not involve the use of
toxic substances. Heat itself, however, can
present an occupational hazard, so proper
safety management is required.
Registration is not normally required for heat
treatments for general pest control. Prior
approval is required for heat treatments to be
used as quarantine treatments. Examples of
approved quarantine treatments for durables
are given in Table 6.5.3, while examples for
perishable commodities are given in Table
6.5.4. Normal safety restrictions apply to the
use of heating appliances in workplaces.
It is necessary to have safety training for
workers.
Cost considerations
Heat treatments normally require a high
capital investment and, in some cases,
Kiln drying of softwood (e.g., Douglas
fir) in the USA costs about US$ 85 to
155 per 1,000 bd. foot, while steam
treatments cost US$ 35 to 60 per 1,000
bd. ft. For hardwoods (e.g., oak, cherry),
kiln drying costs about US$ 100 to 200,
while steam treatments cost about US$
41 to 77 per 1,000 bd.ft. In contrast,
MB fumigation costs only US$ 1 to 3 per
1,000 bd. ft. However, the heat treatments add 30 to 50% extra value to
timber, so the net cost of heat treatments can be zero (US EPA 1996).
For perishable products, heat treatments
generally cost more than MB fumigation
(Paull and Armstrong 1994). The capital
cost of a hot water immersion system
varies from less than US$ 8,000 to more
than $ 200,000. For forced air and
vapour heat systems, the capital costs
vary from US$ 20,000 to about 200,000,
while the capital and operating costs are
estimated to be about US$ 29.40 per
tonne of commodity compared to about
US$ 4.37 per tonne for MB (US EPA
1996). The cost of heat treatment equipment has been reduced in recent years,
however (Williamson 1999).
Structural heat treatments (e.g., for food
facilities) cost approximately 75 to 200%
of the cost of MB fumigation (Mueller
1998), depending on the size of the
treatment area, the source of heat and
the temperature/time equation. If a company already owns heaters, heat treatments are less expensive than MB (Heaps
1998). Otherwise a significant capital
investment is required: One 250,000
BTU platform steam convection heater,
for example, costs about US$ 2,300 in
the USA (Heaps 1998). The operating
cost of heat treatments at a US food
processing plant is US$ 747 to 830 per
1 million cubic feet compared to US$
2,000 to 4,500 for MB (US EPA 1995).

grain-handling machinery.
Do not control Trogoderma.
Historically, inert dusts such as clays and
ashes have been applied to grain to protect
against insect attack (Ebeling 1971, Golob
and Webley 1980, Quarles 1992a,b). More
recent versions of dusts are generally more
effective and require much lower application
rates. Inert dusts can be divided into three
main groups:
a) Traditional materials
Traditional materials include clays, sands,
ashes, earths, phosphate and lime. Some are
used as a protective layer on top of stored
seed, while others are mixed with grain. To
be effective, ashes and dusts generally had to
be mixed with grain at extremely high rates,
such as 40% or more (GTZ 1996).
b)Diatomaceous earth (DE)
DE dusts are composed mainly of silicon dioxide with small amounts of other minerals.
They are produced from the fossilised remains
of diatoms, microscopic single-celled aquatic
plants that have fine shells made of amorphous hydrated silica. They have abrasive and
sorptive properties and are effective against a
wide range of pests when mixed with grain
at rates of 1 kg per tonne (MBTOC 1994). DE
adheres to insect bodies, damaging the protective waxy layer of the insect cuticle or
outer coat by sorption and, to a lesser
degree, by abrasion. Water is lost from the
insect, resulting in death. DE is also known to
repel insects (Korunic 1999).
c) Silica aerogels
Silica aerogels are very light, non-hygroscopic
powders or gels that are formed by a reaction
of sodium silicate and sulfuric acid. They are
chemically inert, non-abrasive and effective at
slightly lower doses than DE formulations.
Modern formulations of inert dusts are typically composed of DE, sometimes combined
with silica aerogels. Formulations differ in
their characteristics and efficacy against
insects. Additives can give improved properties: ammonium fluosilicate, for example,
improves adhesion to treated surfaces and
insects. Certain sources of DE have naturally
higher levels of insecticidal activity, while
some formulations can be activated or
enhanced, for example by heat treatment.
Activated formulations are generally more
effective than untreated DE (Golob 1997,
McLaughlin 1994).
Modern DE formulations used as part of an
IPM system can provide effective pest control
for several years in dry grain and structures.
The application time for DE is short, normally
6.6 Inert dusts
143
less than one day, and DE can control adult
insects in about seven days in favourable conditions (MBTOC 1994). DE dusts remain
effective for years if they are kept in sealed,
dry conditions, but they become ineffective in
moist or humid conditions. Successful use of
DE as part of an IPM system requires knowlege of factors such as grain moisture content,
grain temperature, amount of dockage (chaff,
weed seeds) and broken kernels, grain type
and quality, and insect species and numbers
(Korunic 1999).
144
DE is not suitable for heavily infested commodities. It provides a protective, prophylactic
treatment to prevent pest build-up, so it is
best used as part of an IPM system or as follow-up to another treatment such as aeration
(Section 6.2) or phosphine flow fumigation
(Section 6.7).
Inert dusts are suitable for a relatively small
range of products and uses. There are four
main application areas:
Admixture with stored grains
In several countries, specific formulations of
DE have been approved for admixture with
stored grains, such as wheat, corn, barley,
buckwheat, oats, pea, sorghum, seed, rye,
soybeans, peanuts, cocoa beans and feed
grains. In this technique, DE dust is mixed
with grain when it is bagged or loaded into
silos, bulk bins or bunkers. Enhanced DE is
applied at the rate of about 100 g per tonne
of grain and must be distributed evenly in the
bulk. The moisture content of grain is critical:
Less than 12% prior to storage is recommended (Banks pers. comm.). One application of DE can provide protection from
infestation for several years, because the dust
continues to exert its effects on insects.
When the grain is milled, the dust is removed
along with the grain husks. However, remaining particles in grain can reduce its market
value. Inert dusts can have adverse effects on
the handling qualities of grain, decreasing its
flowability and its bulk density and causing
excessive wear to grain handling machinery.
While some technical problems have been
overcome by new DE formulations (Korunic et
al 1996), these problems tend to prevent the
use of inert dusts in large-scale grain facilities.
Admixtures are considered more appropriate
for stored seed (for planting), smaller-scale
farm storage of animal feed and organic
grains (MBTOC 1994).
Grain surface treatments
DE can be applied to the surface layer of bulk
grain to kill insects in the top layer where
they tend to congregate. This treatment is
best applied as a protective measure for grain
that is already free from insects, after cooling
or flow-through phosphine fumigation, for
example (Bridgeman 1998). When combined
with aeration in a silo, at least 300 mm of DE
is applied on top of the bulk. Moisture content needs to be less than 12% when the
grain is put into storage, and grain temperatures need to be kept below 20°C. In this situation, DE controls immigrant insects as well
as those herded to the top of the silo by the
cooling front (Bridgeman 1998).
Structural treatments
In the USA, certain formulations of DE have
been approved for insect control in structures, such as food handling establishments,
warehouses, restaurants, office buildings,
homes, motels, hotels and schools. These formulations are used on wall and floor surfaces, in cracks, crevices, hiding and running
areas, and under and behind appliances.
DE is used commercially with IPM as a treatment for grain storage facilities in dry regions
of Australia. Normal formulations of DE can
pose a dust hazard to workers applying it to
walls, but this problem can be overcome by
using DE slurries. Although DE is normally
deactivated by moisture, slurries are special
formulations that can be mixed with water
and become reactivated on drying. In this
treatment, empty grain stores are cleared of
debris and thoroughly washed and cleaned.
A slurry of 0.1 kg DE per litre of water is
Spot treatments in structures
DE can provide long-lasting insect control in
cracks and crevices of structures. For example, dusts can be applied inside electrical panels, control panels and “dead” spaces behind
walls before they are closed up, providing
lasting control in locations that are normally
inaccessible (MBIGWG 1998). Spot treatments have been used in this way by a
Canadian flour mill.
Current uses
Inert dusts such as ash and lime have had a
long history of use for grain protection. Use
of modern formulations has increased significantly in the last decade (Bridgeman 1998).
DE is in widespread use for controlling insects
in storage facilities in Australia and is used
commercially for structures in Brazil, Canada,
Europe and the USA (Batchelor 1999). Table
6.6.1 provides examples of commercial uses
of inert dusts. A combination of DE with heat
has been trialled successfully in a Canadian
flour mill (Fields et al 1998).
New formulations to minimise abrasive
properties and protect grain-handling
machinery, such as conveyors, and to
enhance desiccant properties of DE by
promoting its ability to selectively absorb
the waxes of insect cuticles.
New methods of application (Fields et al
1997, Korunic et al 1996).
Trials in damp climates such as the UK
(Cook, Armitage and Collins 1999).
Enhanced DE combined with heat or
in various combinations with heat and
phosphine to achieve higher pest
mortality (Fields et al 1997).

sprayed onto the walls of the storage facility
with a high pressure pump, giving an application rate of about 6 g a.i. per m2. It takes
about 20 minutes to apply the slurry to a
structure that holds 5,000 tonnes of grain
(Bridgeman 1998). One treatment lasts several years and is very effective in controlling
pests in drier regions with relative humidity
below 70% (Batchelor 1999).

Further information on pest species affected
by inert dusts can be found in Korunic (1999)
and Cook, Armitage and Collins (1999). Table
6.6.2 gives examples of stored grain insects
and other pests that are controlled by certain
DE formulations in the USA.
There is also a significant variation in the efficacy of DE in different types of commodities
against the same insect species. The commodities, in order of highest to lowest doses
for LD50 (dose required for killing 50% of
insects) are (Korunic et al 1997):
Rice.
Corn.
Low humidity (normally below about
70% relative humidity).
Oats.
Low moisture content in grain or other
stored commodities.
Wheat.
Pests controlled
Inert dusts, particularly when used as part of
an IPM programme, can effectively manage
insects and mites. DE can act quite rapidly
under favourable dry conditions, achieving
complete mortality of adult insects within
seven days (MBTOC 1994). DE does not
effectively control some pests, notably
Trogoderma. Insect species vary in their susceptibility to DE as follows (most susceptible
to least susceptible):
Rusty grain beetle, Cryptolestes
ferrugineus (Stephens).
Saw toothed grain beetle, Oryzaephilus
surinamensis (L.)
Barley.
Product quality
Admixing inert dusts with grain alters the
angle at which individual grains sit, changing
the way grain flows and making it more difficult to handle. Admixing can also leave visible
dust particles in grain, reducing its market
grade and value. Structural treatments do not
normally suffer from these problems. DE is
odourless and does not stain grain, nor does
it affect the germination and baking properties of grains.
While DE is technically effective for most
stored products, its use is limited by humidity,
dust residue and the handling problems

described above. It is suitable for admixture
with stored seeds that will be used for planting and for smaller scale storage of animal
feed. Some formulations of DE are permitted
for certified organic grains. Surface treatments and structures also offer suitable uses.
Inert dusts are not used for perishable
commodities.
DE treatments are suitable for many geographical regions, provided the relative
humidity in the facility is normally less than
about 70%.
DE has low or no toxicity to mammals and is
widely used as a permitted food additive. As
with any dust, dust from DE is a potential
health hazard to lungs and eyes. Certain
geological sources of DE contain crystabolite,
which is also a hazard to lungs in dusty
conditions.
Precautions and safety equipment are necessary against dust exposure. For structures it is
often feasible to apply DE as a slurry rather
than a powder to minimise the dust.
When DE is admixed with grain, some dust
may remain in the commodity. This does not
pose a health risk to consumers and animals.
DEs are permitted food additives.
Ozone depletion
DE is not an ODS.
consumption
DE is not a greenhouse gas. Like MB, it
requires some energy for extraction, formulation and transportation. Application normally
uses little energy.
Table 6.6.2 Pests that can be controlled by certain DE formulations
– examples from USA
147
DE is extracted from geological deposits in
the ground, so there is a risk of destroying
natural habitats, as with MB extraction from
lakes like the Dead Sea.
148
Mixing DE with grain is not acceptable to
many grain handlers and markets, although
certain milling companies favour its use
(MBIGWG 1998). Structural and surface treatments are often preferable. Consumers find
DE treatment acceptable in that it is a nonchemical treatment.
DE often requires registration. Certain DE formulations are registered as insecticides in
Australia, Brazil, Canada, China, Croatia,
Germany and USA (Batchelor 1999). It is
desirable to limit the amount of crystabolite
allowed in products, as is done in Australia.
Cost considerations
For admixtures, little capital equipment is
required. The material costs for one
treatment are normally higher than the
cost of MB, costing approximately US$
8.80 per tonne of grain in some countries (GTZ 1998).
For structures such as grain stores, the
capital cost of a high pressure pump for
slurry applications is about US$ 4,200 in
Australia, but the pay-back period is
rapid. Over 2 years, the total average
annual cost (capital and operating) is
US$ 3,200 for DE slurry treatment compared to US$ 5,150 for MB fumigation
(Batchelor 1999).

6.7 Phosphine and
other fumigants
Advantages
General technique and pest control
approach akin to MB fumigation.
Effective against a broad range of pests
including rodents.
150
Fumigants diffuse well in commodities
to reach pests.
Phosphine is available worldwide.
Some fumigants provide rapid
treatments.
Fumigants can provide a direct replacement for MB in some situations.
Disadvantages
tions. Fumigants are highly toxic to humans,
other mammals and insects. Their use is generally controlled under regulations covering
pesticides, hazardous substances and occupational health and safety. Properly conducted
fumigations are complex procedures that
should be carried out only by trained fumigators in situations where they are able to work
to high safety standards.
In applying a fumigant, the aim is to ensure
that a certain concentration of gas is kept in
the commodity or space for sufficient time to
kill the target pests. The appropriate concentration, exposure time and manner of application will depend on a number of factors
including those listed below (ASEAN 1989,
Graver and Annis 1994, MAFF 1999):
Nature of infestation (e.g., pest species,
stage of life cycle, position in
structure).
Phosphine involves long treatment time
compared to MB.
Nature and quantity of commodity and
commodity packaging — or nature and
volume of structure.
Like MB, fumigants provide no on-going
protection against pests after the
treatment.
Temperature and humidity of commodity
and treatment areas.
Fumigants can only be used in the countries and for the commodities and situations for which they have been
registered.
Fumigants are highly toxic, requiring
trained personnel, special safety precautions and equipment.
Like MB, fumigants can leave undesirable residues in commodities or affect
the quality of certain commodities or
materials.
Fumigants are toxic chemicals that act against
pests while in a gaseous state, though they
may be applied in liquid or solid formulations
(Bond 1984, Price 1985, Stark 1994). They
have relatively low molecular weight and are
generally capable of diffusing rapidly through
commodities and buildings to reach infesta-

Necessary safety precautions for operators, site staff and the public.
Monitoring systems.
Fumigants approved for such purposes can be
very effective for pest management and disinfestation for official QPS purposes.
Fumigations can be carried out in commodities or structures enclosed in gas-tight sheets
or in places (such as silos, buildings, ship
When applying phosphine to a bag stack, for
example, the stack is covered with gas-tight
fumigation sheets and sealed around the
base with sand snakes or similar devices.
Tablets of aluminium phosphide are placed
within the enclosure, releasing phosphine
gas. After the necessary treatment period
(5 to 15 days), the stack is aerated and the
sheets removed.
Fumigants control the pests present in the
commodity or structure at the time of fumigation, but they do not provide on-going protection against pests. Thus, it is necessary to
use some other protective measures or to refumigate after three to six months.
Phosphine is the only fumigant other than
MB that is registered in many countries for
disinfestation of durable commodities.
Sulphuryl fluoride is registered in several
countries for structures and a few other
applications. Other fumigants have very limited registration, and are described briefly
below.
Phosphine
Phosphine (hydrogen phosphide or phosphorus trihydride, PH3) is a colourless gas with a
characteristic odour. It is used extensively for
durable commodities, principally stored cereals and legumes, and is approved for some
quarantine applications (Table 6.7.5).
Normally phosphine is generated from solid
formulations of aluminium phosphide (e.g.,
pellets, tablets or sachets) that decompose on
contact with water vapour in the air to
release phosphine gas inside the fumigation
enclosure. Adequate temperature and humidity are required; the equilibrium relative
humidity produced by the commodity should
be more than 30%. Solid formulations based
on magnesium phosphide release phosphine
faster and can be used at lower temperatures, e.g. 5˚C.
More recently developed phosphine-generating equipment, such as the Horn generator,
has allowed rapid production of phosphine
gas on site and is being used in several countries, including Chile and Argentina (Horn
1997, Horn and Luzaich 1998, Kawakami
1998). Phosphine gas in pressurised cylinders
as a 2% phosphine mixture with carbon dioxide propellant is widely used in Australia, and
a similar formulation is in the process of registration in the USA (Winks 1990, Winks
1993, Mueller 1998). Phosphine with nitrogen gas in cylinders has been developed in
Germany (Böye 1998). When phosphine is
supplied as a gas it can be released at lower
temperatures, and doses can be precisely
administered.
For phosphine, a commodity temperature of
at least 15°C is recommended, but certain
pests are susceptible down to 5°C with long
exposures (MBTOC 1998). Effective exposure
periods are typically 5 to 15 days, depending
on the temperature, target species and developmental stages of pests. Use of phosphine
supplied as a gas may allow a slight reduction
in the treatment times.
Phosphine has the following characteristics:
Good penetration into stored products
(better than MB).
Effective against a broad range of insect
pests, although resistance has developed
in several species.
Disperses well in enclosed spaces.
Rapidly disperses on ventilation after
fumigation.
Can leave residues in food commodities
or affect marketable qualities in certain
cases (e.g., taint and colour change in
walnuts).
Generally no negative effects on the germination of treated seeds.
holds, gas-tight shipping containers and specially designed chambers) provided the
required gas concentrations can be maintained for sufficient time to kill pests.
151
Forms an explosive mixture with air if the
concentration exceeds 1.8% by volume
at normal atmospheric pressure; this
level is not reached in normal fumigation
practice.
152
Reacts with noble metals, such as copper, silver and gold, corroding items such
as electric cables, electrical equipment,
telephones, sprinkler heads and computers. Measures can be taken to avoid or
lessen these effects (Brigham 1998,
Brigham 1999, Mueller 1998).
Insect populations can develop resistance to
phosphine relatively easily (Chaudhry 1997)
due to problems such as insufficient treatment times and low concentrations caused by
leaky enclosures. Presently resistance can be
managed by longer exposure periods and
improved gas-tightness. Important steps for
resistance management are described in
Taylor and Gudrups (1997). Codes of practice
and descriptions of the application methods
for phosphine for durable products can be
found in many sources (ASEAN 1989, Banks
1986, Bond 1984, Degesch America 1997,
Graver and Annis 1994, GTZ 1996). New
phosphine formulations and techniques are
also outlined in numerous documents (Taylor
and Harris 1994, Reichmuth 1994,
Agriculture and Agri-Food Canada 1996,
Horn 1997, Horn and Luzaich 1998, Mueller
1998, Fields and Jones 1999).
Sulphuryl fluoride
Sulphuryl fluoride or sulfuryl fluoride (F2SO2)
is an inorganic, colourless, odourless gas supplied as a liquid in pressurised cylinders. In
several countries, including the USA, Sweden
and China, it is registered for specific uses,
such as structures where food is not present
or wood products. It is used primarily to kill
termites and wood-damaging insects in structures, such as residences and non-food facilities, and is suitable for wood and wood
products. It is approved in some countries as
a quarantine treatment for certain non-food
durables (Table 6.7.5).
Sulphuryl fluoride requires a short fumigation
period of approximately 24 hours and has a
6- to 8-hour aeration period (MBTOC 1998).
Application rates are determined by factors
such as target pests, their life stages, temperature at the pest site, volume of fumigation
space, degree of sealing/leakiness and target
exposure period. High doses (up to 10 times
the normal rate for adult termites) are
required to kill the egg stage of many
insects and can lead to high chemical
residues (Bell et al 1998, Taylor et al 1998).
Longer exposure periods and good sealing
techniques allow for use of lower doses.
The characteristics of sulphuryl fluoride
Volatilises readily, giving good penetration and distribution.
Effective against a broad range of pests.
Short treatment time (similar to MB).
Faster aeration than MB.
Low sorption to materials.
No objectionable odours or colours in
treated materials.
Does not react with materials normally
found in structures.
Non-flammable.
Not registered for use where food, feed
and medicinal products are present,
because it can leave residues; permitted
residue levels (food tolerances) have not
been established.
Descriptions of the procedures for using sulphuryl fluoride in structures can be found in
DowElanco (1995) and treatments for quarantine in USDA-APHIS (1998).
Other fumigants
Fumigants that have been used commercially
and are available and registered in certain
countries include the following:
Carbon bisulphide or carbon disulfide
(CS2) is used in parts of Australia and
Carbon dioxide (CO2). Refer to information on Controlled and modified
atmospheres in Section 6.4.
Ethyl formate (C3H6O2) is now restricted to dried fruit and processed cereal
products. It was formerly used as a grain
fumigant, but registration has lapsed in
most countries. It acts rapidly (Hilton and
Banks 1997) but is highly sorbed by
commodities. Adequate distribution can
be difficult.
Ethylene oxide (C2H4O) is used in
some countries to reduce microbial contamination in food commodities such as
spices, and provides insect control coincidentally. It was widely used for insect
control on grain and dates in the past,
but has been withdrawn in many countries because it is carcinogenic in animal
tests and can produce potentially carcinogenic residues (NIEHS 1991). It is
more appropriate for non-food uses such
as artifacts and archive materials
(MBTOC 1998). Ethylene oxide is flammable, so it is normally supplied in mixtures with inert diluents such as carbon
dioxide or HCFCs.
Hydrogen cyanide (HCN) is currently
registered in a few countries for specific
uses, such as treating aircraft in France.
It was previously widely used as a fumigant for durable commodities, mills and
other structures. It provides a rapid treatment against rodents, where permitted.
It can be lethal to humans by skin
absorption alone at the concentrations

In-transit fumigation
154
Where regulations permit, fumigation of bulk
and bagged commodities can take place on
board ship while commodities are in transit.
In-transit carbon dioxide treatments are
carried out on groundnuts exported from
Australia. In-transit fumigation with phosphine is a well-developed technology (Davis
1986, Leesch et al 1978, Redlinger et al
1979, Semple and Kirenga, Zettler et al
1982) but requires ships of appropriate
design and stringent safety precautions
(Snelson and Winks 1981, IMO 1996). In this
method the slow action of phosphine does
not interfere with the flow of trade through
export ports and thus presents a feasible
alternative to some rapid on-shore MB treatments (MBTOC 1998).

To overcome some of the disadvantages of
traditional fumigants, a combination of heat,
phosphine and carbon dioxide has been
developed (McCarthy 1996, Agriculture and
Agri-Food Canada 1996, Mueller 1996,
1998). Carbon dioxide at high pressure is
used to treat beverage crops, nuts and spices
(Gerard et al 1988, Prozell and Reichmuth
1991, Prozell et al 1997).
Current uses
Phosphine is registered in most countries and
widely used for bulk and bagged grain and
other durable commodities, such as herbs,
spices and tobacco. It is also used for fumigating wooden objects, paper and other
durable materials of vegetable origin.
Sulphuryl fluoride has been used for many
years in the USA, principally to control wooddestroying termites in structures (Table 6.7.3).
Use of other fumigants is restricted to the
countries and commodities/uses for which
they are officially permitted or “registered”
for use as pesticides.
Carbonyl sulphide is being considered
for registration for durables, including
timber (MBTOC 1998, Banks et al
1993a, Plarre and Reichmuth 1996,
Zettler et al 1998).
Other potential fumigants under investigation include cyanogen, methyl isothiocyanate, methyl phosphine, ozone, and
propylene oxide (MBTOC 1998, Griffith
1999).
New formulations of phosphine are
being tested to overcome normal phytoxicity to perishable comodities
(Kawakami 1999).
The manufacturer of sulphuryl fluoride is
investigating the possibility of extending
the registration to cover food commodities and other uses (Chambers and
Millard 1995, Schneider and Williams
1999).
Additional work is being conducted to
develop combination treatments.

Pests controlled
Fumigants, like MB, can control a wide range
of pests. Some are approved as quarantine
treatments for specific pests/commodities
(Table 6.7.5).
Phosphine
With sufficient temperature and adequate
exposure period, phosphine is effective in
controlling major stored product pests, such
as confused flour beetle, granary weevil,
Indian meal moth, khapra beetle, lesser grain
borer, Mediterranean flour moth, rice weevil,
rust-red grain beetle and saw-toothed grain
beetle (MBTOC 1998). Table 6.7.4 shows the
treatment times for various pests. As indicated in the table, phosphine is highly effective
against all stages of khapra beetle
(Trogoderma granarium) in grain, but this
treatment has not been approved for quarantine purposes (Bell et al 1984, 1985, MBTOC
1998). Phosphine is effective in controlling
bark beetles, wood-wasps, longhorn beetles
and platypodids at 15°C or more, but it is not
typically effective against seed-infesting
nematodes (MBTOC 1998).
The tolerance of the developmental stages of
insects to phosphine varies considerably. Eggs
and pupae are much more tolerant of phosphine than larvae or adults, so fumigation
must be continued long enough for the more
tolerant eggs and pupae to continue their
development to larvae and adults (ASEAN
1989). Control of mite eggs is difficult, but
for certain commodities control can be
achieved by carrying out a second fumigation
after the eggs have been allowed to hatch
(an interval of 2 weeks at 20°C or 6 weeks at
10°C) (Bowley and Bell 1981). Information on
phosphine’s efficacy against pest species and
life stages can be found in Phillips (1998).
Sulphuryl fluoride
Sulphuryl fluoride is effective against major
insect pests of timber, including bark beetles,
wood-wasps, longhorn beetles, powderpost
beetles and dry wood termites, and pests
commonly found in structures such as wooddestroying beetles, furniture and carpet beetles, clothes moths, cockroaches and rodents
(MBTOC 1998). It is toxic to the post-embryonic stages of insects, but the eggs of many
species are tolerant especially at low temperatures. Information on the efficacy of sulphuryl
fluoride against a range of pest species and
stages is provided in Bond and Monro (1961),
Kenaga (1957), Mizobuchi et al (1996),
Reichmuth et al (1996), Thoms and
Scheffrahn (1994), Dow Agrosciences.
Carbon dioxide
Refer to information given in Section 6.4.
Product quality
Phosphine can leave residues in food products and can taint certain commodities such
as walnuts, herbs and spices. Normal formulations of phosphine are phytotoxic to perish-
able commodities. Phosphine is less phytotoxic than MB to seeds, so it can be used where
germination is important. Sulphuryl fluoride
does not normally affect the quality of materials found in structures, but leaves residues in
food commodities.
such as timber, wood products and artifacts.
Examples of some approved quarantine uses
are given in Table 6.7.5.
Fumigants must only be used for the commodities and uses for which they have been
officially permitted, and pesticide registration
authorities should be able to provide up-todate information relating to your country or
state. Fumigants can be effective in bulk bins,
silos, bags, stacks, chambers, structures and
transportation, provided sufficient sealing and
exposures can be achieved.
Phosphine is effective for a wide range
of grains and durable commodities
including oilseeds, expeller cake, meal,
flour and seeds for germination and
wooden items. It is also suitable for
structures in cases where corrosion will
not be a problem.
Sulphuryl fluoride is suitable for structures that do not contain food or feed,
as well as vehicles, railcars, furnishings
and non-edible durable commodities,
Fumigants can generally be used in temperate to tropical climates. However, temperatures of more than 15°C are desirable for
phosphine use, while relative humidity greater
than about 30% is necessary for aluminium
phosphide use.
Fumigants are by nature highly poisonous.
They pose acute toxicity risks if mis-handled,
and some pose chronic health risks. (Toxicity
data sheets are given in Annex 3.)
The occupational Permissible Exposure
Limit (PEL) for phosphine is 0.3ppm
(0.4 mg/m3) in the USA. Chronic poisoning symptoms from significant exposure
include anemia and potentially fatal pulmonary edema, while exposure to higher
concentrations can cause renal and liver
failure, coma and death (NTP 1990).

The occupational Permissible Exposure
Limit for sulphuryl fluoride is 5 ppm (y
mg/m3) in the USA. Chronic exposure to
significantly higher levels than the PEL
may result in fluorosis of teeth and
bones, while short-term inhalation exposure to high concentrations may cause
respiratory irritation followed by pulmonary edema, numbness and central
nervous system depression (NTP 1990).
The toxicity of sulphuryl fluoride to
mammals by inhalation is similar to that
of MB (Bond 1984).
The emissions of fumigant gases after treatment can pose safety risks to staff and
neighbouring communities. Some fumigant
formulations are flammable.
Handling of fumigants requires full safety
training, safety equipment and implementation of appropriate management and emergency procedures. Occupational safety
authorities have set exposure limits and can
provide guidance on safety procedures and
equipment for registered fumigants.
Fumigants should only be handled by fully
trained personnel. Other safety controls and
requirements include:
Respiratory protection.
Detailed safety equipment.
Training and licensing.
Personal monitors.
Regular medical check-ups.
Fumigant chemicals should be stored in
appropriate conditions in special locked areas.
Information on safety procedures can be
found in HSE (1996a, 1996b) and IMO (1996).
Fumigants leave residues in food products.
Unless precautions are taken, phosphine
tablets or pellets can leave powdery residues
on commodities that are likely to contain
unreacted metal phosphides (MAFF 1999).
The Codex Alimentarius Commission of the
Food and Agriculture Organization (FAO) and
the World Health Organization (WHO) has
established maximum residue limits for some
fumigant residues in specific foods. Residues
are also generally controlled under pesticide
residue regulations at national or state levels.
The fumigants in this section are not known
to be ODS. However, carbon disulfide has
been noted as a catalyst for ozone depletion
if the gas reaches the upper atmosphere
(WMO 1991).
consumption
Fumigants described in this section are not
known to be greenhouse gases, except for
carbon dioxide. Like MB, the products consume energy during their manufacture and
transport. Some formulations consume energy during use.
After a fumigation has finished, the unused
gases are released to the air, contributing to
local air contamination. Some durable commodities will desorb or slowly release fumigants for a long period after fumigation.
Waste from solid phosphine formulations can
be a source of environmental pollution; it is
normally deactivated in water and detergent
and then placed in landfill sites. Large cylinders
containing fumigants are normally re-used.
Phosphine is widely used for food commodities and well accepted by supermarkets and
purchasing companies. Sulphuryl fluoride is
likewise well accepted by customers for structural treatments and non-food commodities.
Consumers in general do not like chemical
treatments for food products, however, and
there is increasing public concern about safety issues for communities near fumigation
sites.
All fumigants have to be registered as permitted pesticides for specific commodities and
uses. Phosphine is registered in many countries, while the other fumigants are registered
in some cases. Registration may be the
responsibility of the government authorities
that control pesticides and, in some cases,
the authorities responsible for food, grain and
quarantine. The storage, sale, use and/or
transportation of fumigants are often restricted by regulations on hazardous substances
and occupational safety and may also be
restricted by local by-laws. In-transit fumigations are subject to shipping regulations and
codes of the International Maritime
Organisation (IMO 1996).
Cost considerations
Phosphine generally requires less equipment than does MB, but the chemical
products often cost more than MB. In
Zimbabwe, for example, the chemical
costs were approximately US$ 0.14 per
tonne of grain for phosphine, compared
to about $ 0.09 for MB. In Indonesia the
chemical cost was about US$ 0.20 to
0.29 for phosphine and about $0.09 for
MB. For six months of grain storage in
Indonesia, the equipment and operating
costs were about US$ 0.61 to 0.79 per
tonne for phosphine, compared to
$ 0.50 for MB (Sidik 1995, Miller 1996).
For six months of grain storage in the
Philippines, the total fixed and variable
costs were about US$ 7.17 per tonne for
phosphine and about $ 6.30 per tonne
for MB (NAPHIRE 1995, Miller 1996).
When longer phosphine treatment is
involved, additional fumigation sheets
may be required, and those additional
sheets add to costs. In Zimbabwe, for
example, each additional sheet would
cost approximately US$ 2,330 (Miller
1996).
The chemical cost of sulphuryl fluoride is
higher than MB, for example, about US$
0.75 to 1.37 per ft2 for sulphuryl fluoride compared to $ 0.69 to 1.37 for MB
for eliminating drywood termites in a
large commercial structure (EPA 1996).

About the UNEP DTIE
The UNEP Division of Technology,
Industry and Economics
The mission of the UNEP Division of
Technology, Industry and Economics is to help
decision-makers in government, local authorities, and industry develop and adopt policies
and practices that:
Chemicals (Geneva), which promotes
sustainable development by catalysing
global actions and building national
capacities for the sound management of
chemicals and the improvement of
chemical safety world-wide, with a priority on Persistent Organic Pollutants
(POPs) and Prior Informed Consent (PIC,
jointly with FAO).
Make efficient use of natural resources.
Ensure adequate management of
chemicals.
Incorporate environmental costs.
Reduce pollution and risks for humans
and the environment.
The UNEP Division of Technology, Industry
and Economics (UNEP DTIE), with its head
office in Paris, is composed of one centre and
four units:
The International Environmental
Technology Centre (Osaka), which
promotes the adoption and use of environmentally sound technologies with a
focus on the environmental management of cities and freshwater basins, in
developing countries and countries in
transition.
Production and Consumption (Paris),
which fosters the development of cleaner and safer production and consumption patterns that lead to increased
efficiency in the use of natural resources
and reductions in pollution.
Energy and OzonAction (Paris), which
supports the phase-out of ozone depleting substances in developing countries
and countries with economies in transition, and promotes good management
practices and use of energy, with a focus
on atmospheric impacts. The UNEP/RISØ
Collaborating Centre on Energy and
Environment supports the work of the
Unit.
Economics and Trade (Geneva), which
promotes the use and application of
assessment and incentive tools for environmental policy and helps improve the
understanding of linkages between trade
and environment and the role of financial institutions in promoting sustainable
development.
UNEP DTIE activities focus on raising awareness, improving the transfer of information,
building capacity, fostering technology cooperation, partnerships and transfer, improving
understanding of environmental impacts of
trade issues, promoting integration of environmental considerations into economic policies, and catalysing global chemical safety.
Annex 1: About the UNEP DTIE OzonAction Programme

The OzonAction Programme
164
Nations around the world are taking concrete
actions to reduce and eliminate production
and consumption of CFCs, halons, carbon
tetrachloride, methyl chloroform, methyl bromide and HCFCs. When released into the
atmosphere these substances damage the
stratospheric ozone layer — a shield that protects life on Earth from the dangerous effects
of solar ultraviolet radiation. Nearly every
country in the world — currently 172 countries — has committed itself under the
Montreal Protocol to phase out the use and
production of ODS. Recognizing that developing countries require special technical and
financial assistance in order to meet their
commitments under the Montreal Protocol,
the Parties established the Multilateral Fund
and requested UNEP, along with UNDP,
UNIDO and the World Bank, to provide the
necessary support. In addition, UNEP supports
ozone protection activities in Countries with
Economies in Transition (CEITs) as an implementing agency of the Global Environment
Facility (GEF).
Since 1991, the UNEP DTIE OzonAction
Programme has strengthened the capacity of
governments (particularly National Ozone
Units or “NOUs”) and industry in developing
countries to make informed decisions about
technology choices and to develop the policies required to implement the Montreal
Protocol. By delivering the following services
to developing countries, tailored to their individual needs, the OzonAction Programme has
helped promote cost-effective phase-out
activities at the national and regional levels:
Information Exchange
Provides information tools and services to
encourage and enable decision makers to
make informed decisions on policies and
investments required to phase out ODS. Since
1991, the Programme has developed and disseminated to NOUs over 100 individual publications, videos, and databases that include
public awareness materials, a quarterly
newsletter, a web site, sector-specific technical publications for identifying and selecting
alternative technologies and guidelines to
help governments establish policies and
regulations.
Training
Builds the capacity of policy makers, customs
officials and local industry to implement
national ODS phase-out activities. The
Programme promotes the involvement of local
experts from industry and academia in training workshops and brings together local
stakeholders with experts from the global
ozone protection community. UNEP conducts
training at the regional level and also supports
national training activities (including providing
training manuals and other materials).
Networking
Provides a regular forum for officers in NOUs
to meet to exchange experiences, develop
skills, and share knowledge and ideas with
counterparts from both developing and
developed countries. Networking helps
ensure that NOUs have the information, skills
and contacts required for managing national
ODS phase-out activities successfully. UNEP
currently operates 8 regional/sub-regional
Networks involving 109 developing and 8
developed countries, which have resulted in
member countries taking early steps to implement the Montreal Protocol.
Refrigerant Management Plans
(RMPs)
Provide countries with an integrated,
cost-effective strategy for ODS phase-out in
the refrigeration and air conditioning sectors.
RMPs have to assist developing countries
(especially those that consume low volumes
of ODS) to overcome the numerous obstacles
to phase out ODS in the critical refrigeration
sector. UNEP DTIE is currently providing specific expertise, information and guidance to
support the development of RMPs in 60
countries.
Support the development and implementation of national ODS phase-out strategies
especially for low-volume ODS-consuming
countries. The Programme is currently assisting 90 countries to develop their Country
Programmes and 76 countries to implement
their Institutional-Strengthening projects.

The Internet has many other websites that provide research data and practical information on post-harvest pest
control methods and products; search using key words for species of pests, specific techniques, equipment,
products or applications of interest (eg. Khapra beetle + phosphine). It is generally best to search for key words
that are unique or specific to the topic of interest; for example, search for “grain aeration controllers” rather
than a general term like “grain technology.”
Technical information can also be found on websites of companies and suppliers; refer to tables in each Section and
the corresponding contact information in the Annex, or search the Internet for the names of specific companies.
For websites on health and safety, toxicity and exposure limits, refer to the introduction in Chemical Safety Data
Sheets in the Annex.
In following any web addresses provided here, keep in mind that many sites undergo frequent reorganization. If
the address listed is not working, it may be useful to try again using only part of the address. For example, if
the page listed as http://www.epa.gov/ozone/mbr/mbrqa.html does not work, try

address to take you to an organization’s main home page, such as http://www.epa.gov. From there, you can
often run a search for the topic of interest or locate the appropriate link.

A Word from the Chief of UNEP DTIE’s
Much of the Montreal Protocol’s success can be attributed to its ability to evolve over time to
reflect the latest environmental information and technological and scientific developments.
Through this dynamic process, significant progress has been achieved globally in protecting the
ozone layer.
As a key agency involved in the implementation of the Montreal Protocol, UNEP DTIE’s
OzonAction Programme promotes knowledge management in ozone layer protection through
collective learning. There is much that we can learn from one another in adopting effective
alternatives to methyl bromide.
Sourcebook of Technologies for Protecting the Ozone Layer: Alternatives to Methyl Bromide,
which provides technical information on a range of alternative technologies to replace methyl
bromide, is neither comprehensive nor exhaustive. Technologies will emerge or be further
refined as countries move ahead with methyl bromide phase out.
I encourage you to share information on methyl bromide alternatives with the OzonAction
Programme so that we can inform others involved in this issue about available technologies and
how they can be adopted. Send us an e-mail, fax or letter about new technologies in this sector
and your experiences in replacing methyl bromide. We will consider it as an important part of
collective learning.
Based on the feedback and information received, UNEP will update this sourcebook on a periodic basis to reflect the latest technological developments. We will also disseminate this information through a variety of channels, including the OzonAction Newsletter and the OzonAction
Programme’s website (www.uneptie.org/ozonaction.html). If we use the information you provide, we will send you a free copy of one of our videos, publications, posters or CD-ROMs as
thanks for your cooperation.
So take a pen and write to us. Let us learn collectively to protect the ozone layer.
