Section 10 – Calibration and Spraying Techniques

Section 10

CHAPTER 1
CALIBRATION FOR SPRAYING
___________________________________________________________________________________
Calibration, for our purpose, may be defined as the procedure of checking or altering the total amount
of solution applied to a given area. Neglecting this procedure before applying pesticides can result in
injury and expense. At present, pesticide labels contain detailed information about the range of rates and
total solutions to be applied per acre (or hectare). If the information contained on the label is confusing
or controversial, obtain technical or expert assistance. Labels also yield information on application
equipment, nozzle and strainer screen limitations, pressure recommendations, and safe handling
procedures. ALWAYS STUDY LABELS IN GREAT DETAIL.
Total solution is the amount of liquid (pesticide plus a carrier usually water) to be applied per acre or
hectare. Almost all of the work involved in calibration goes into determining total solution. It requires
careful calculation and execution of the procedures involved. Most product labels indicate that a quantity
of product be applied in a number of gallons or litres per acre or hectare. If a range of total solution is
indicated (100–300 litres per hectare; in at least 200 litres per hectare, for example) keep in mind that
recalibration will be necessary if your total solution delivered does not fall within the specified range.
Generally, three variables can be altered to produce the desired sprayer calibration:
1
Flow rate is the amount of liquid being sprayed. It is usually expressed in litres or gallons per
minute. The flow rate is quite easily altered with most spraying devices. It can be increased or
decreased by changing nozzles; adding or removing swirl plates (sometimes referred to as metering
orifices, these plates have different sized centre holes); changing the pressure-rate of pumping
on backpack sprayers; and changing the setting on gravity feed type sprayers / backpack mist
blowers.
2
Speed is simply the rate at which the sprayer is travelling. During calibration it will be expressed
in metres or feet per minute. It is easy to change speed with backpack sprayers simply change
your walking speed. Speed changes can be more difficult with tractor-mounted sprayers as the
PTO speed must be maintained at a certain RPM recommended in the sprayer instructions. So
tractor speeds are limited by the range of gears available, and how fast the terrain will allow you
to drive the tractor safely.
3
Swath width is the distance covered with the spray. In most cases this can be difficult to change
with the exception of the boomless or fieldjet broadcast nozzles. For example, the KLC 5 nozzle
on a backpack sprayer can be adjusted from a swath width of 6–25 feet (1.8–7.5 m), depending
on how high above the ground the nozzle is held.
Hydraulic Backpack and Broadcast Calibration
The following calibration procedure can be used for backtank sprayers and tractor-mounted boom sprayers.
Though the delivery systems are different, the principles are still the same.
Before using any spraying device ensure that it is clean and working properly.
Section 10
10.1.2.
CALIBRATION FOR SPRAYING
___________________________________________________________________________________
1
Fill the sprayer and begin spraying to determine swath width while holding the nozzle at a
comfortable height above the ground. The swath width can be adjusted by increasing the height
of the nozzle. When spraying bands with a boom assembly the swath width will only include the
actual sprayed areas and not the width of the boom.
Example: Swath Width = 3.0 feet
2
Calculate walking speed (travelling speed) by recording the number of feet travelled in 60
seconds. Try this out on the area to be treated with a full backtank of water to ensure you can
actually maintain that walking speed while spraying. The walking speed MUST be consistent to
ensure even application of the pesticide product.
Example: Walking Speed = 115 feet per minute.
3
With a full backtank of water pumping at a constant pressure to maintain an even flow rate
record the number of fluid ounces discharged in one minute. A pressure gauge is extremely
helpful in keeping a constant flow rate, and every effort should be made to install one on the
sprayer. When using more than one nozzle the flow rate must be the total of all nozzles.
Section 10
10.1.3.
CALIBRATION FOR SPRAYING
___________________________________________________________________________________
Example: Flow Rate = 17 ounces per minute.
4
Use the following formula to determine total solution being delivered per acre.
Total Solution per acre =
(Flow Rate x 160 oz./imp. gal.) x 43560 sq.ft./acre
Swath Width x Walking Speed
Example:
(17 oz./min. x 160 oz./imp.gal.) x 43560 sq.ft./acre
3.0 feet x 115 feet/minute
=13.4 imp. gal. per acre total solution
5
If the total solution is too great then reduce pressure (pump less) or increase swath width or
walking speed.
If total solution is too little then increase pressure (pump harder) or decrease swath width or
decrease walking speed. After altering one of the variables, repeat the above steps to obtain the
new total solution being delivered.
6
Once the desired total solution has been achieved, use the following formula to determine amount
of product to add per tank:
Product per tank =
Tank Capacity in gallons x Product per acre required
Total Solution per acre delivered
Section 10
10.1.4.
CALIBRATION FOR SPRAYING
___________________________________________________________________________________
Example:
Tank Capacity is 3 gallons
Application Rate is 50 fl. oz. of Vision (product per acre required)
Total solution (see above) is 13.4 gallons
3.0 gallons x 50 ounces
13.4 gallons
= 11.2 oz. Vision per tank
To determine the tank mix, subtract the amount of product (Vision) from the tank capacity.
There are 160 fl. oz. in 1 imp. gal., so 11.2 oz. =11.2/160 imp. gal. = 0.07 imp. gal.
Amount of carrier (water) required is 3 – 0.07 = 2.93 imp. gal.
Tank mix should be: 11.2 oz. product (Vision) and 2.93 imp. gal. of carrier (water).
Backpack Mistblower Calibration
Before using any spraying device, ensure that it is clean and working properly.
1
Fill sprayer and operate under field conditions to determine swath width. It is helpful to have
an assistant when measuring this. Try to avoid swaths wider than 25 feet (7.6 m) as they tend to be
more inconsistent than narrower swaths.
Example: Swath Width = 20 feet.
2
Determine walking speed by recording the number of feet travelled in 60 seconds. Try this
out on the area to be treated with a full backtank of water.
Section 10
10.1.5.
CALIBRATION FOR SPRAYING
___________________________________________________________________________________
Example: Walking Speed = 100 feet per minute.
3
Fill sprayer to the top or to a specific mark on the tank and spray for one minute. Record the
number of ounces required to fill the tank to the original level. This volume represents the flow
rate.
Example: Flow Rate = 30 ounces per minute.
4
Use the following formula to determine total solution being delivered per acre:
Total solution per acre =
(Flow Rate x 160 oz./imp. gal.) x 43560 sq.ft./acre
Walking Speed x Swath Width
Example:
(30 oz./min. x 160 oz/imp. gal.) x 43560 sq.ft./acre
100 ft./min. x 20 ft.
= 4.1 imp. gal. per acre
5
If total solution is too great then reduce flow rate (using the adjustable valve) or increase walking
speed.
If total solution is too little then increase flow rate (adjustable valve) or decrease walking speed.
After altering one of the above variables, repeat above steps to determine new total solution.
Section 10
10.1.6.
CALIBRATION FOR SPRAYING
___________________________________________________________________________________
6
Once the desired total solution has been achieved, use the following formula to determine the
amount of produce to add to each tank.
Product per tank =
Tank Capacity in imp. gal. x Products per acre required
Total Solution per acre delivered
Example:
Tank Capacity is 2.0 imp. gal.
Application Rate is 60 ounces of Vision.
2.0 imp. gal. x 60 ounces
4.1 imp. gal.
= 29.3 oz. per tank.
To determine the tank mix, subtract the amount of product (Vision) from the tank capacity.
There are 160 fl. oz. in 1 imp. gal., so 29.3 oz. = 29.3/160 imp. gal. = 0.18 imp. gal.
Amount of carrier (water) required is 2.0 – 0.18 = 1.82 imp. gal.
The tank mix should be: 29.3 oz. product (Vision) and 1.82 imp. gal. of carrier (water).

CHAPTER 2
SPRAYING TECHNIQUES
___________________________________________________________________________________
Backpack Hydraulic Sprayer
The lever-operated backpack is most commonly available with a diaphragm or a piston pump. The
piston is most useful where high pressures are required. The diaphragm is designed for use with
suspensions (wettable powders, for example) which can cause damage to the piston chambers. Pesticides
can be applied very accurately with the backpack when proper technique and preparation are employed.
A pressure gauge should be installed on the wand side of the trigger valve. Gauges are usually available
from the manufacturer or purchased locally. The pressure gauge will allow a constant flow rate to be
applied removing one of the most critical variables involved with herbicide application.
Before calibration, check the operation of the sprayer. Cover the following points: pressure gauge
operation; nozzle tip properly installed and oriented; leaks in hose or cover; trigger valve operation; and
a cleaned, flushed tank.
Most backpacks do not have agitators, so wettable powder (WP) and suspension type pesticides should
be premixed to form a slurry, then added to the tank with the remaining water. During application the
tank should often be shaken vigorously to keep the spray solution well-mixed.
Using a spray shield will allow you to apply contact sprays close to young seedlings. These shields are
readily available in a variety of sizes or can be homemade (a rectangular windshield washer container
with the bottom cut out). In plantations it is easy to line up passes (actual lines walked along while
spraying) by flagging the start and end of each pass (distance between passes being equal to the swath
width) and then following the adjacent row of trees to the end of the pass.
In wild stands where there are no rows to follow the entire length of each pass may be flagged, or an
offset pole method can be used. One pole is placed one swath width over from the starting point, and
another pole is placed at the end of the first pass. The first pass is made, the beginning of the second pass
is measured, and the pole is erected on the third pass. The second pass is made and the procedure is
completed again. In this way one person can both spray and preset the offset (range) pole for their next
pass coming back. The pole should be cut to a length that can be used to measure the passes.

10.2.2.
SPRAYING TECHNIQUES
___________________________________________________________________________________
Pressure gauge set-up
Tractor-Mounted Sprayers
The basic operating principles and calibration procedures for tractor-mounted sprayers are very similar
to the backpack.
Before calibration, check the points described in the backpack section. When calibrating, the PTO
should always be at the recommended speed for the sprayer being used.
Most tractor sprayers have detailed calibration instructions. Follow those methods whenever possible.
Although most sprayers are equipped with bypass agitators, when wettable powders are used a jet agitator
or a lower bypass type (a pipe at the bottom of the tank with holes in it) should be used.
Operating a boom sprayer in a natural stand is in most cases impossible, yet the development of the
boomless nozzle allows us to use this system. Swaths between 20 and 60 feet (6–18 m) can be achieved
from one cluster of various nozzles (no boom). Although these nozzles are best suited to preemergent
herbicides, it is possible to apply contacts as well. Passes should be marked individually for tractormounted applicators the wide swath makes it difficult to avoid overlap or misses. In field situations a
foam marking system can be installed to help line up the passes. Foam markers actually deposit drops of
foam at the end of the boom. The foam is not permanent, but it lasts long enough to act as a guide for the
return pass.
Section 10
10.2.3.
SPRAYING TECHNIQUES
___________________________________________________________________________________
Backpack Mist Blowers
The motorized backpack mist blower is an air carrier type sprayer. The spray solution is gravity fed (in
most cases) to a shear nozzle, where the air current atomizes the solution and carries it to the intended
target. This type of sprayer is best suited for insecticides but may also be used for directed contact
herbicide applications. Mist blowers are not suited and should never be used for preemergent herbicides.
When applying suspension type sprays, follow the same procedure outlined in the backpack hydraulic
section. The greatest drawback for herbicide applications is the variation of swath width. Bearing this in
mind, keep swaths as narrow as possible (20–25 feet, or 6–8 m), and direct the spray level with the
ground. Swaths should be clearly flagged across the area to be treated so the operator does not have to
stop to line up or move poles.
Applications should be made in the direction of wind to reduce pesticide exposure to the operator.
When using the mist blower, never direct the full force of the spray into the trees. Raise or lower the
flexible air hose to prevent this.

CHAPTER 3
NOZZLES
___________________________________________________________________________________
Nozzles
A nozzle is basically a device through which a liquid is emitted, broken into droplets, and spread over a
specific width. Changing nozzle sizes and styles allows us to increase or decrease total solution, swath
width, and droplet size.
The nozzle component consists of a body, filter, tip, cap and in some cases a swirl plate. The body is
available with a built-in check valve to reduce the dripping of the nozzle after the boom or wand has
been shut off. Filters range in size from 50 to 200 mesh. The larger mesh filters are required on tips with
very small openings. When using flowable liquids, powders, and so on consult the labels for recommended
filter and tip sizes.
Swirl plates are designed for use on disc and cone type tips. They reduce the range of drop sizes produced
by the nozzle and create a hollow or solid cone spray pattern. Tips are now manufactured in a variety of
materials, including brass, plastic, stainless steel, and hardened stainless steel.
Tips should be checked frequently for wear and replaced when they deliver 10 per cent more volume
then intended. The average size of droplets will decrease with an increase in pressure. When larger
droplets and lower drift potential are required as with herbicides nozzles should be operated at their
lower pressure range. If this is not possible, a larger nozzle will allow a decrease in pressure.
Flat Even Nozzles
Flat even nozzles are designed for band treatment of pre- or postemergence herbicides. They are available
in similar shapes and sizes to flat spray nozzles. The main difference is a rectangular spray pattern rather
than the tapering effect found with the flat spray nozzle. This allows an even spray pattern without
underdosing the edges. These nozzles may be used on booms in various numbers or on backpacks for
band treatments.
Section 10
10.3.2.
NOZZLES
___________________________________________________________________________________
Full- and Hollow-Cone Nozzles
Full- and hollow-cone nozzles produce a round spray pattern. This is useful when good coverage is
required (the spray is directed to a target from more than one direction). These nozzles are generally
used at higher pressures, creating smaller-sized droplets that are preferred with insecticide and fungicide
applications. The full-cone nozzle can be used with foliar herbicides as the higher flow rate and larger
droplets create a more suitable spray.
Using swirl plates in these nozzles dictates the type of pattern either full or hollow. They may also be
used to increase or decrease flow rate, when an adjustment is needed to correct total solution delivered
per acre. When installing swirl plates the nib side of the plate should always face the nozzle body and
not the nozzle tip. These nozzles can be used on booms for broadcast treatments or backpacks for spot
treatments with foliar applied herbicides.
Impact or Boomless Nozzles
Impact or boomless nozzles create a wide swath and coarse spray droplets suitable for preemergent
herbicides. Swaths of 3 feet (0.9 m) can be achieved, making this nozzle useful in difficult terrain.
Although large drops are produced, wind dramatically affects the swath width, due to the thin sheet of
liquid produced before droplet formation. This nozzle is useful for application of preemergent herbicides,
where spray coverage is less important and application is difficult. They may be used on boom equipment
(smaller sizes), tractor-mounted boomless, and backpack sprayers.
Section 10
10.3.3.
NOZZLES
___________________________________________________________________________________
Flat Spray Nozzles
Flat spray nozzles are available in a variety of flow rate sizes and spray angles. The spray angle is the
angle in degrees at which the spray is emitted. Flat spray nozzles may be used singly or in various
numbers spaced evenly along a boom. When used on a spray boom, the height of the boom should be
adjusted to allow for 30 per cent overlap of spray patterns.
Using larger spray angle nozzles (110E) will create better uniformity and allow the boom to be lowered
(to achieve the 30 per cent overlap). This also lessens drift potential the spray travels a shorter distance
to the target. These nozzles are used mainly for herbicide (pre- or postemergence) boom sprayers
(broadcast treatments) creating a very uniform distribution pattern over the width of the boom. They
may also be used on backpack sprayers at pressures as low as 20 p.s.i., although uniformity over the
swath may be altered slightly.
Important note: Once an application system has been calibrated, record the number of millilitres or
ounces output over a 30-second period. With this number in mind, a 30-second daily check will determine
if there is nozzle wear or if some other problem is affecting flow rate (such as a clogged screen, pump
malfunction, and so on).

CHAPTER 4
PESTICIDE RECERTIFICATION CREDIT POINT (PRCP) PROGRAM
____________________________________________________________________________________
Background
In December 1996, it became mandatory for all users of commercial class or restricted class pesticides
to become certified. The pesticide certification program is administered by the Nova Scotia Department
of Environment and Labour (NSDEL).
To acquire a pesticide applicators certificate you must successfully complete the appropriate NSDEL
pesticide certification exam. You must then apply to NSDEL for the appropriate certificate(s). There is
a $40.00 fee and certificates are valid for a period of five years from the date they are issued. Under
Section 8(4) of the Pesticide Regulations a certificate holder must recertify every five years to maintain
a valid certificate. Recertification can be obtained by acquiring 15 Pesticide Recertification Credit
Points (PRCPs) during the five-year period in which the certificate is valid or by writing an exam at the
end of the five-year period.
The Pesticide Recertification Credit Point (PRCP) Program
The Pesticide Recertification Credit Point (PRCP) program has been developed to allow individuals to
accumulate credits for participating in approved training sessions. This program allows a certified
individual the option of recertifying by collecting 15 Pesticide Recertification Credit Points (PRCPs)
over a five-year period. Otherwise certificate holders will be required to rewrite the exam at the end of
the five-year period.
Recertification by credit point is the preferred method of recertification for pesticide applicators and
vendors. The program is based on the idea that continuing education rather than examination once every
five years will enable applicators and vendors to keep abreast of new developments and changing
technology in pest management. This ongoing training is designed to promote continuous improvement
and is a key tool for promoting responsible use, pollution prevention, and for reducing the risks associated
with pesticide use.
Definitions
Recertification: The certification of a pesticide applicator after their original certificate has expired.
Options for recertification: Candidates can be recertified by writing a certification exam or by obtaining
sufficient Pesticide Recertification Credit Points (PRCPs). Certificate holders will be considered for
the PRCP option if sufficient training is available for them to obtain the necessary 15 PRCPs.
Acceptable format for training for recertification: Acceptable training formats include instructor led
courses, seminars, field days, interactive computer programs, facilitated viewing of videos, self-study
with verified testing, user group meetings where pesticide related topics are covered, or workshops in
which the continued attendance of candidates and active participation can be verified. Courses in First
Aid and WHMIS will only be considered if they are specifically designed for pesticides.
Section 10
10.4.2.
PESTICIDE RECERTIFICATION CREDIT POINT (PRCP) PROGRAM
____________________________________________________________________________________
Unacceptable format for training for recertification: Courses dealing with the following types of
information will not be recognized for recertification: business aspects of farm or company management,
crop fertilization and irrigation, plant production varieties, storage and marketing of commodities, video
tapes on their own, self-study without verified testing, crop scouting services.
Trainers/Providers: Groups authorized to provide training include user groups or agricultural
organizations, private or academic training groups, agribusiness and professional associations, and
government departments.
Responsibilities of Trainers/Providers: Generally trainers/providers will be responsible for the design
and delivery of training events and proposed assignment of point values to the training event. A syllabus
for each training event along with proposed point values of the training shall be submitted to the NSDEL
for approval as a PRCP course prior to delivery of the course (Appendix 3).
Trainers/providers will be responsible for submitting the completed PRCP Attendance and Credit
Form (a sample form is provided in Appendix 4) to the NSDEL. All training events may be subject to
audit by the NSDEL.
Point System
In the Pesticide Recertification Credit Points (PRCP) program, one hour of acceptable training is equal
to one credit. Half (0.5) credits can be awarded for half-hour sessions. The relationship between training
time and credits is simple, otherwise it becomes difficult to assign credits and to audit the process.
Acceptable training is training that addresses one or more of the ten topics included in the National
Standard for Basic Knowledge Requirements for Pesticide Education in Canada (Appendix 1) and that
meets the definition of acceptable format for training for recertification.
In general, courses should cover new issues and/or provide a refresher on information covered in the
initial certification training. Emphasis should be given to updating certificate holders on new technologies,
improved practices, Integrated Pest Management (IPM), and new least-toxic pest control products.

APPENDIX 3
REQUIREMENTS FOR TRAINERS/PROVIDERS
The following procedure has been established for Trainers/Providers of recertification events.
1.
The trainer/provider must submit the recertification request to the nearest NSDEL Recertification
Officer (see below). The program event must be submitted at least 30 days prior to the scheduled
event date and include:
(a) A description of the training program indicating subjects that will be covered.
(b) A program agenda.
(c) A draft copy of the course announcement if one is to be sent to prospective attendees. The
announcement should not imply in any way that the Nova Scotia Department of Environment
and Labour is the course sponsor.
(d) The name and credentials of all trainers/providers as well as the name and address of the
event sponsor.
2.
Trainers/providers may propose the point values of their own training sessions based on the
criteria outlined in the Procedure for Assignment of Credit Values.
3.
The NSDEL Recertification Officer will respond to the trainer/provider and if in agreement with
the course and PRCPs assigned will assign a code number for the specific training program.
4.
To be eligible for credit, all attendees must show a current NSDEL Pesticide Certification Card,
and must register using the PRCP Attendance and Credit Form (a sample form is provided in
Appendix 4). A copy of this form must be forwarded to the NSDEL Recertification Officer in the
region where the attendee is certified. If attendees at an event are from more than one region the
trainer/provider must send the information to each region according to where the attendees are
from. This is extremely important as all certificates are managed according to the region where
the individual lives. A copy of this information must also be retained by the trainer/provider.
Section 10
10.4.7.
PESTICIDE RECERTIFICATION CREDIT POINT (PRCP) PROGRAM
____________________________________________________________________________________
5.
The trainer/provider must issue each attendee a certificate of proof of attendance that lists the
following information.
(a)
Attendee’s name, address, and pesticide certificate number.
(b)
Name, place, and date of the training course.
(c)
Number of credits assigned.
(d)
Signature of the instructor and applicant.
(e)
Training event code number assigned by NSDEL.
6.
The trainer/provider should remind attendees that they must maintain their own record of
recertification credits earned. They must also be informed that a list of attendees and credits
earned will be forwarded to the NSDEL.
7.
The NSDEL will be responsible for keeping a record of PRCPs accumulated by the various
certificate holders. At the conclusion of an individuals’ five year certification term the individual
will be notified whether they have accumulated sufficient PRCP points for recertification without
writing the exam.
