Devastating Citrus
Greening Disease in
South Florida


Citrus Canker Very Close


13011ce Sale W11P

Dr. Pete Timmer (above) presented a training
on how to survey for and identify citrus
canker symptoms. If you missed it, the
training is also available on DVD (see Dr.
Timmer). Color pdf files of citrus canker
symptoms (as well as diseases with similar
symptoms), and a key to assist in identifying
symptoms can be printed from the "Citrus
Canker Resources" link on the CREC website.

With two citrus canker finds within 10
miles from CREC, Center Director Dr.
Harold Browning reminded employees what
is at stake should citrus canker be found at
CREC and all our citrus destroyed. "We could
stand to lose everything decades of research,
unique and irreplaceable material, and the
ability to conduct research and education on
citrus," Dr. Browning told the CREC audience
at a citrus canker training session on Aug. 30.
"If you're not personally decontaminating,
you are breaking the law," he added, referring
to the state's mandatory decontamination
of personnel, vehicles and equipment upon
entering and leaving a citrus greenhouse
or grove. Dr. Browning also said that

itrus greening, a devastating bacterical
disease that many consider the worst
disease of citrus, was confirmed in early
September in South Florida by the USDA
and the Florida Dept. of Agriculture.
Diseased trees decline rapidly, become
unproductive and die in as little as a few years.
According to a Florida Dept. of
Agriculture press release, this is the first
detection of citrus greening in the U.S.
The disease is caused by bacteria in the

Meet CREC's
Postdocs, Visiting Scientists
and Ph.D. Scientists!

"Posters and Pastries"
A Research Symposium -

Thirty of CREC's postdocs, visiting and
other Ph.D. scientists will be on hand
with scientific posters and available
to answer questions. This is a great
opportunity to interact with others
and learn about current projects in an
informal setting.
Come on over and meet our scientists!

All personnel are encouraged to attend;
the event is also open to the public.

Coffee, orange juice, donuts, muffins and
other goodies will be served.


Center Director Dr. Harold Browning
addressed the CREC community at
a citrus canker training session on
Aug. 30, stressing the importance
of citrus decontamination. When
citrus canker is found in Florida, all
citrus within 1900 ft. is destroyed,
and the area placed under a
minimum two-year quarantine. This
would be devastating to CREC.

Florida Dept. of Agriculture inspectors are routinely monitor
compliance, watching workers through binoculars and citing
those not following proper decontamination procedures.
Last month, citrus canker was found in groves at the UF/
IFAS Indian River Research and Education Center in Fort Pierce,
requiring the destruction of all their citrus. "One hundred
acres all of IRREC's [citrus] research, is gone," Dr Browning
Citrus canker is a bacterial disease that causes lesions on the fruit,
leaves and stems, fruit and leaf drop, and a general decline in tree
health. The state of Florida has a mandatory eradication program

CREC, USDA and other scientists are conducting research on
treatments and management strategies, as well as the development of
resistant varieties. However, a safe, effective treatment is not in the

Food Tanker Sanitation Workshop
Over 60 people attended
a food tanker sanitation
SI workshop at CREC on Au-
gust 24. The workshop
covered food microbiology,
sanitation of food tankers,
inspections, regulatory is-
sues and other topics re-
lated to tanker sanitation
for the transport of juices,
dairy products and bever-
ages. The afternoon ses-
sion included a panel discussion of instructors, inspectors and industry representa-
tives (above). Speakers included Dr. Renee Goodrich, workshop organizer (CREC),
Dr. Keith Schneider (UF/IFAS Food Science and Human Nutrition Gaines-
ville), Dr. Dan King (Florida Citrus Processors Assoc.), Paul Winniczuk (CREC),
and Dr. R. Schmidt (UF/IFAS Food Science and Human Nutrition Gainesville).

Scenes From The -
44th Annual Citrus 5I
Packinghouse Day ....... ........
Last year's Citrus Packinghouse- L .'''
Day was cancelled as Florida
prepared for the arrival of
Hurricane Frances. This year's
event, with seminars and exhibitors
for Florida' fresh citrus industry, proceeded on schedule. Above left: Richard Kinney of the Florida Citrus Packers Association,
presided over the event. Center: Dr. Bill Miller discussed advantages of color grading of fruit prior to degreening. Dr. Miller
also serves as the exhibits coordinator for Packinghouse Day. Dr. Renee Goodrich is the local arrangements coordinator, and
Dr. Mark Ritenour from the UF/IFAS Indian River Research & Education Ctr. in Fort Pierce is the program coordinator. Far
right: Juan Muniz from Primus Labs in Santa Maria, Calif., presented the keynote address, "How to Pass a Food Safety Audit."

Above left: Dr. Gene Albrigo answers questions after his presentation,
"Prospects for Good Fruit Quality This Year." Above right, Ledger
reporter Kevin Bouffard (left) speaks with Mark Estes from the Florida
Dept. of Agric. and Consumer Services, after his presentation on "Citrus
Canker Update on Eradication Progress and Regulatory Issues."
Estes reported that before last year's hurricanes, 15,000+ acres of commercial citrus had been eradicated; since August 2004,
there have been over 46,000 acres of citrus destroyed, attributed to the spread of the disease by the hurricanes. Far right, Dr. Tom
Burks, UF/IFAS Agricultural and Biological Engineering, discussed research progress on a mechanical harvesting system for fresh
citrus. He showed video of a robotic harvesting arm in action (above right). Photos by Gretchen Baut and Monica Lewandowski.

symptoms are leaf yellowing, including
yellowing of leaves on a single shoot,
branch or section of the tree canopy.
The bacteria are transmitted primarily
by insect vectors (citrus psyllids). The Asian
citrus psyllid (Diaphorina citri Kuwayama)
was first detected in Florida in 1998.
At a briefing on citrus greening held
at CREC on Sept. 8, state entomologist
Susan Halbert said that citrus greening
was well established in southern Dade
County. Severe symptoms have been
found on pummelo and grapefruit,
although the disease has also been found
on limes, oranges, kumquats and possibly
other citrus varieties in South Florida.
Spread of citrus greening by the insect
vector is potentially much greater than
with citrus canker. Host plants for the
Asian citrus psyllid are primarily citrus
and other genera in the family Rutaceae,
including orange jasmine (Murraya
exotica) and and other species of Murraya.

Dr. Stuart visited
Illc Reserva Biologica

in the terra fire lowland rainforest, about 60 kilometers northwest
of Manaus, Amazonas State. The field station is operated
by INPA as part of the Large-Scale Biosphere-Atmosphere

Ariau Towers Jungle Hotel, the only hotel complex
at tree top level in the Amazon Rainforest.
"The hotel was great," Stuart says. "It was in the
igapo [flooded] forest, with the buildings up on stilts and
connected by catwalks. It's really kind of neat, surrounded
by nature preserves a great place for ecotourism."
In addition to visiting the INPA field station with colleagues
Dr. Katia Rodrigues, (Mycology Department, FIOCRUZ,
Ministry of Health, Rio de Janeiro) and Carlos Alberto Cid
Ferreria, (Department of Botany, Instituto National de Pesquisas
da Amazonia (INPA), Manaus), Dr. Stuart participated in several
other exciting activities. He went piranha fishing, watched squirrel
monkeys and parrots at the hotel, and observed the local ant species.
"I saw the large stinging Ponerine ant," says Dr.
Stuart enthusiastically. "There were also leafcutter ants."
Dr. Stuart says one of the most interesting aspects of his
trip was the opportunity to hear ants stridulate (the term used to
describe the act of making sounds by rubbing body parts together).
"Ants are one of my areas of interest," says Dr. Stuart, who
studies ant predation on Diaprepes root weevils, a pest of citrus
and other crops. "But I've never gotten the chance to hear them.
This trip I was able to
observe ants large enough
to hear stridulate."
Dr. Stuart greatly.
