Citrus Canker Concerns
Two citrus canker workshops were held at CREC to train
employees on proper precautions to prevent the spread of
canker. According to Dr. Pete Timmer, the three major ways
that canker is spread in the state are:
1) canker infected plants are moved from one area of the
state to another;
2) canker-infested leaves, fruit, and other plant material are
carried on or in vehicles from an infested location to a clean
3) the bacterium is carried as a contaminant on vehicles,
picking sacks, ladders, gloves, etc.
In Florida, workers who handle citrus plants, tissues or fruit,

Plant debris must be cleaned
from vehicles upon leaving a
grove to prevent the spread of

New Varieties Program
Over 60 citrus growers, packers and
plantbreeders attended a Nc\\ Fresh Citrus
Varieties Day" at on Dec. 8.
The meeting formally introduced a Fresh
New Varieties Development Program, which
involves the Florida Citrus Packers, Florida
Citrus Mutual, the University of Florida/
IFAS, the USDA/ARS Ft. Pierce, the
FDCAS/Division of Plant Industry and the
Florida Department of Citrus. According to
Richard Kinney, Executive Director of the
Florida Citrus Packers program will help
direct Florida's citrus breeding programs
for the fresh citrus industry.
The program is led by a technical
committee of scientists and an oversight
committee of fresh citrus industry
representatives. The technical committee,
headed by Center Director Dr. Harold
Browning, Center Director of the UF/IFAS
CREC, will be responsible for the
introduction of three new varieties each
season. The oversight committee, chaired
by Quentin J. Roe, will offer policy
guidelines in the development and
evaluation of new varieties.

Dunn's Unit Receives Highest Award
Assoc. Press, Nov. 2003 -The Presidential
Unit Citation was awarded to the 1st Marine
Expeditionary Force by Navy Secretary Gor-
don England. The award is the highest given
by the U.S. military to an entire unit, which
includes Alex Dunn (son of CREC's Denise
Dunn and her husband, Jerry). "This is the
Oscar of unit awards," said Steven Mackey,
head of the Marines' military awards branch.
"The Medal of Honor is the most coveted
award for individuals. The Presidential Unit
Citation is the most coveted award for units."

The citation commends the Marines for
their "extraordinary heroism and outstand-

history, moving nearly 500 miles from the
Kuwait border to areas north of Baghdad.
