Citrus Canker in Polk County; Concern Grows
Employees Reminded of Citrus Decontamination Procedures
Citrus canker was confirmed in a
Frostproof nursery and groves owned by
BenHill Griffin Inc., marking the first citrus
canker find in Polk County since a
statewide outbreak in 1916.
All trees within 1900-ft. radius from
infected trees must be destroyed, an area
that encompasses approximately 250 acres.
Over 1000 acres of citrus trees, owned by
Ben Hill Griffin Inc., and 255 acres owned
by Alico, Inc., are being removed and

There is a vehicle wash station north of the center near the farm
operations buildings. Decontamination involves the removal of
plant debris from vehicles, equipment and clothing, and washing
with appropriate and approved decontamination materials, before
entering citrus groves/greenhouses and upon exiting. There are
separate chemicals approved for personnel and clothing vs. vehicles
and equipment. CREC is also subject to inspections regarding
proper decontamination procedures.
Also, if you suspect citrus canker or have questions regarding
plant symptoms on any citrus, you should not bring in or move the
plant material doing so could spread the disease if it is indeed
citrus canker. Arrangements should be made for inspections on-
site. Questions can be directed to your supervisor or to Dr. Timmer

GAINESVILLE, Fla -Exercise in coldwater
instead of warm water may increase people's
appetites, making it harder for them to lose
extra pounds, a University of Florida study
Results indicate people may consume
more calories after exercising in cold water,
according to Lesley White, a UF researcher
who designed the study to better
understand why aquatic exercise is often
less successful than equal amounts of
jogging or cycling for people who want to
"It's possible that individuals who
exercise in cooler water may have an
exaggerated energy intake following
exercise, which may be a reason why they
don't lose as much weight," said White,
an assistant professor in the College of
Health and Human Performance. "So it may
not be the exercise itself that causes the
problem because you can match the
exercise energy expenditure; rather it's the
increased eating after the exercise is over."
White said her research is not meant to
suggest that swimming or aquatic exercise
is ineffective for building physical fitness.
In fact, water exercise is suggested for
people who are overweight because the
buoyancy given by the water makes
exercising easier for people with joint or

Meet... The Schumann Lab
by Meredith Jean Morton
Dr. Arnold Schumann and his laboratory group study citrus
nutrition, fertilizers, soil science and associated production practices.
The lab utilizes new technology using computer and satellite-based
technology, such as geographical information system (GIS) and
geographical positioning system (GPS) tools, to collect data on trees,
soil, weather and other characteristics and help citrus growers make
better management decisions on fertilization, irrigation and other
practices to optimize tree growth and production. Examples include
technology for measuring soil electrical conductivity, soil organic
matter, nutrient content, water tables and other soil chemical
characteristics, and correlating soil data with citrus production.
The lab includes a group of people with diverse backgrounds and
experiences. They are working to develop the use of precision
agriculture technology with applications in citrus nutrition and soil
science, as well as Nitrogen Best Management Practices for Ridge

"With more people involved, that would
be something we could start up again,"
Albrigo says. "The competition was fun."
The regular players usually enough to
play between three and five people per side

interested in recruiting more females to come
out and join the team. Burrage says there
are a few women who play infrequently.
"We really hope more people will come
out and join us," Burrage says. "We have
a lot of fun, and it's a great way to get some

Preparing a poster for a scientific
meeting? Water and rain can ruin an
ink-jet printed poster, and laminating can
be expensive and require adequate lead
time. A quick and inexpensive
alternative is to give your poster a light
coat or two of clear spray lacquer (make
sure the ink on the poster has had time
to dry sufficiently). While it won't make
your poster waterproof, it will offer some
water protection and could avert a
disaster. Clear spray lacquer is available
at many stores where hardware, crafts or
home improvement supplies are sold.
Talk to the Photolab if you're interested
in trying this out.
