Field Days a Success
The entire faculty and staff at the SWFREC are pleased to welcome Dr. Robert
Ebel to the center in the newly created position of associate professor of citrus hor
ticulture and plant physiology. Dr. Ebel comes to us from Auburn University,
where he worked for ten years as a pomologist. Dr. Ebel received his undergradu
ate degree in horticulture from the University of Missouri in 1981. He earned his
M.S. in horticulture in 1985 from Washington State University, where he also
earned his Ph.D. in horticulture in 1991.
Dr. Ebel's work at SWFREC will focus on lowering production costs for citrus .' I /
growers by identifying limitations of production, conducting research to address those issues, and relating
results back to growers. Specifically, he will help develop il.. rl,.. .1 .1. ;.; for growers to adopt mechanical
l-I r;. .. of processed oranges. His research emphases will include the development of abscission com-
pounds as aids to mechanical har-
vesting and optimizing tree health
to promote recovery after harvest.
Dr. Ebel's research is being con-
ducted conjointly with the UF/
IFAS Citrus Research and Educa-
tion Center in Lake Alfred. His
extension responsibilities include
communicating research results to
industry personnel and developing
recommendations for optimizing

Safety Day Educates Farm Personnel
Nearly 180 farm workers and managers from throughout Southwest Florida participated in the 17th
Annual UF/IFAS Southwest Florida Farm Safety Day on Saturday, June 2. The afternoon portion of
the program, a tractor rodeo contest, was cancelled because of -ii ,r. 1.,;i weather associated with
Tropical Storm Barry; however, the morning portion was a huge success. Four educational sessions
Tractor and equipment safety, conducted by Mariano Vasquez of A. Duda and Sons
Wildfires and fire safety, conducted by Gerry LaCavera of the Florida Department of Forestry
Snakes, venomous insects, and other dangerous critters, conducted by Kiley Harper with the UF/
IFAS Palm Beach County Extension Service
CPR basics for farm workers, conducted by the Hendry County Health Department

I Field Days Tout Citrus, Vegetable Research
Two field days were conducted at the SWFREC this past spring.
Nearly fifty growers attended April's Citrus Mechanical Harvesting Field Day, which included presen-
tations about UF/IFAS research currently under way. SWFREC's agricultural economist, Dr. Fritz
Roka, was joined in the presentations by Dr. Jackie Burns and Dr. Reza Ehsani, both from the UF/

SWFREC vegetable research trials hosted the field portion of the field day.
The Spring Vegetable Field Day brought 100-plus growers and industry representatives to the
SWFREC in May. Three research trials spotlighted work being done on whiteflies, including tomato
varieties resistant to tomato yellow leaf curl virus, whitefly control for the management of watermelon
vine decline, and a new insecticide for whitefly control. Additional trials focused on biological and
S chemical control of broadmites and whiteflies on pepper and eggplant, controlled-release fertilizers and
their impact on tomato .;i rl and yield, and irrigation needs of pepper plants.
