February 2012--Volume 21
COORDINATOR’S CORNER
By Patricia Porchey, Urban Horticulture Extension Agent
Along with a new year comes familiar faces, but in
new positions. At the Membership meeting two new
officers were elected: Rene McCarthy is the new
Secretary and Judy Ligon is the new treasurer on your
Executive Committee. Nancy Moore is returning as
President and Debbie Shapiro as Vice President. In
addition, Frank Saracino has joined the committee as
the class of 2010 representative. Please let your representatives know if you have grant or program ideas.
The budget is always foremost on the agenda at the
initial Committee meeting of the year. As you know,
the funds generated by the annual plant sale are earmarked for MG grants as well as the new Demonstration Garden.
Sarasota County is mandating new requirements for
Advisory Committee checking accounts so this is
now a priority that Committee members are working
on. It‟s possible that a 501C3 may be needed for this
account. The current Balance Sheet is attached as
well as the revised Bylaws.
Now that we have our first quarterly award
winners, be thinking about who to nominate
for the second quarter. Send your nominations to Nancy Moore.
namoorefl@verizon.net
The County Fair is approaching and this is the
time of the year 4-H especially needs your
help. They will need you to help judging the 4hers as they give their demonstrations and
public speaking topics as well as their creative
ventures at the fairgrounds. They also need
help with record books. It‟s amazing what
these children can do and every year I continue
to appreciate what the 4-H staff and the club
leaders accomplish with these young people.
You too can see up close their achievements
by volunteering. Please let Sheila Holland
know you are willing. sholland@scgov.net
I hope you‟re excited about all the opportunities for you and our community in 2012.

DEMONSTRATION GARDEN UPDATE
By Stacy Spriggs, Community & School Gardens Coordinator
I am very pleased to have recently joined the UF/IFAS Sarasota County Extension.
As part of my duties here, I will be working on the Demonstration Garden to be
located at the Extension office at Twin Lakes Park. This concept originated from the
dedicated efforts of Master Gardener volunteers, and I am grateful for all the progress
you have made with it thus far. My primary role is coordination of the Steering Committee of stakeholders interested in the garden—including Master Gardeners, the
Sarasota Bay Estuary Program, the Southwest Florida Water Management District,
Sarasota County Parks and Recreation, and Sarasota County Environmental Services.
During the recent Steering Committee meeting, we worked with the stakeholder
group to reach consensus on the Mission Statement and the title for the Garden.
“Sarasota’s Green Gardens” was the top candidate. You are all invited to attend future
meetings and we look forward to your continued involvement as the project progresses. Please contact me or visit our website at http://sarasota.ifas.ufl.edu/Hort/
GreenGarden.shtml
I am also working with Community Gardens in our area to provide technical assistance and education to support thriving and sustainable community gardens in Sarasota County. Similarly, I am getting to know the many teachers involved in local
School Gardens. These teachers often have very little time available in their busy
schedules to maintain gardens. Extension is developing a curriculum and technical
assistance program to help schools start and maintain school gardens in coordination
with agriculture, horticulture, and nutrition education.
Please contact me if you are interested in volunteering at one of our many Community or School Gardens. We can work together to find a location that is convenient for
you. Hours and times vary depending on individual needs and contacts. 232-5317,

Note from our in-service speaker:
From Lynda Eppinger, who is a Parks Naturalist with Sarasota County Parks and Recreation. Lynda was our speaker at the
January 18th in-service meeting
If any of the gardeners are looking for some volunteer hours, two projects that always need attention at Urfer Park where
Lynda works, include weeding in the landscape beds around the historic house and serving as docents for our open houses.
For the latter task, we generally ask for a commitment of two hours twice a month. Anyone interested may contact Lynda at
941-650-2487.
If you come upon an exotic wildlife pest that needs removal, call 861-5000, 1-888-IVEGOT1 (483-4681), or visit IVEGOT1.org for more information. She and Brian Pavlina have been trained to remove these exotic pests in our county.
That’s the sound of detecting Grape root pests
Equipped with high-tech acoustic equipment, University of Florida researchers are listening for the sound of insects gnawing
on grapevine roots.
Specifically, they‟re after the grape root borer, which in the larval stage feeds inside grape roots and damages the plant, according to a news release.
Growers can use the pesticide chlorpyrifos to control the pest, but it is a restricted-use material.
The alternative control is mounding, a labor-intensive and expensive practice that involves piling dirt around the base of infected grapevines. The goal is to prevent adults emerging from underground cocoons from ever making it to the surface.
Will Sanders, a former University of Florida entomology graduate student, used a machine called an accelerometer to convert
vibration into an electrical signal, then another to convert the signal into sound.
Although Sanders says it was easy to differentiate between the sounds of underground insects and other noises, he says it was
difficult to tell grape root borer sounds from other insects.
Even if growers were to count all of the insect sounds as positive, they could still reduce the number of sites that require
mounding by up to 75 percent.
Nurture a Plant for the Upcoming Plant Sale
Someone in my community has a Norfolk Pine in a 10 gal container that they are willing to give us for the plant sale. It looks like
there may be 3 plants in the pot and all are about 3-4 ft tall. Is there a master gardener that could take care of and possibly divide
the trees into other containers for the plant sale? I cannot take care of the trees because of limited space at my condo. If interested
please call Elizabeth Lucchesi 363-7931.

Congratulations Ruth!
Contaminated Orange Juice, but not in Florida Orange Juice
It has been reported that low levels of the fungicide carbendazim have been found in orange juice. Fungicides are used to
prevent the spoilage of fruits and vegetables by molds. Carbendazim is not registered for use in the US, but is registered for
use in many other countries. FDA will begin testing orange juice and concentrate being imported into the US, and will deny
entry of any product in which this fungicide is found. The FDA has concluded that the amounts of carbendizam being
found in orange juice do not present a risk to human health, and are therefore not asking for a product recall. This is clearly
a regulatory issue, not a public health issue, and we are confident that FDA makes its decisions based on the best available
science.
Hybrid Grapefruits Won't Interact With Medications
Lindsay Goldwert, New York Daily News
Grapefruit may be low in calories and loaded in vitamin C but when combined with
certain medications, the results can be toxic.
Scientists at the University of Florida have created a hybrid fruit that has all the refreshing tartness of grapefruit without the dangerous compounds called furanocoumarins that can interact with certain blood pressure and heart medications, reports Scientific American.
"There are certain relatives of grapefruit that we call pummelo, some of which are very, very low or have no furanocoumarins
in them at all. And we've crossed these with ordinary grapefruit." said Fred Gmitter, a citrus geneticist at the University of
Florida

New breakthrough shows promise for affordable plastic solar energy cells
GAINESVILLE, Fla. — University of Florida researchers report they have achieved a new record in efficiency with a prototype solar cell that could be manufactured using a roll-to-roll process. “Imagine making solar panels by a process that looks
like printing newspaper roll to roll,” said Franky So, a UF professor in the department of materials science and engineering.
Industry has eyed the roll-to-roll manufacturing process for years as a means of producing solar cells that can be integrated
into the exterior of buildings, automobiles and even personal accessories such as handbags and jackets. But, to date, the
photovoltaic sheets cannot muster enough energy per square inch to make them attractive to manufacturers.
The UF team has crossed the critical threshold of 8 percent efficiency in laboratory prototype solar cells, a milestone with
implications for future marketability, by using a specially treated zinc oxide polymer blend as the electron charge transporting
material. The full report outlining the details of their latest laboratory success in solar cell technology is published in the Dec.
18 online version of Nature Photonics.
The researchers said the innovative process they used to apply the zinc oxide as a film was key to their success. They first
mixed it with a polymer so it could be spread thinly across the device, and then removed the polymer by subjecting it to intense ultraviolet light. John Reynolds, a UF professor of chemistry working on the project, said the cells are layered with different materials that function like an electron-transporting parfait, with each of the nano-thin layers working together synergistically to harvest the sun‟s energy with the highest efficiency. Reynolds‟ chemistry research group developed an additional
specialized polymer coating that overlays the zinc oxide polymer blend. “That‟s where the real action is,” he said. The polymer blend creates the charges, and the zinc oxide layer delivers electrons to the outer circuit more efficiently.”
