HLB Lab Opens


Field Day Announced


Staff News


Upcoming Events


The new HLB Lab housed at the SWFREC opened its doors on February 4, and more
than 1,000 citrus samples already had been received by lab personnel by mid-March.

The HLB Lab is the state's newest facility dedicated to the Real Time Plymerase Chain.....
Reaction (PCR) molecular diagnosis of Huanlongbing (HLB), commonly known by "
growers as greening, a bacterial disease transmitted by leafhopper insects. HLB's rapid
spread since first being discovered in the Miami area in 2005 threatens numerous citrus .\
groves across south and central Florida. Growers are attempting efforts to control the
spread of HLB in groves with the use of insecticides. However, there is no known cure for HLB, and
infected trees ultimately will die.

The SWFREC owes much gratitude to growers, elected officials, and industry representatives for their
efforts to convince the Florida legislature to appropriate $250,000 in state funds to establish the HLB Lab
in Immokalee. Southwest Florida has quickly become the hotbed area for the disease, as evident by the
number of samples from the area that have come into the lab.

Each individual suspect-HLB sample submitted to the lab must be prepared by hand, which constitutes the
most time-consuming aspect of the -li.; .... rh process. Once DNA extractions are conducted, samples
then are analyzed in the PCR machine at the rate of nearly 90 per machine run.

The HLB Lab currently operates with two fulltime staff members: molecular geneticist Dr. Diana Schultz
and lab technician Paul Julian. Additional assistance in preparing samples is offered by other technicians in
SWFREC's Plant P .rl,. .1... department on an as-needed basis. The lab will continue to accept samples at
no charge until the state's allocated funding is depleted, at which time additional funding will be sought if
the need persists.

For detailed information about how to collect and submit citrus samples, growers should review the HLB
Sample Submission Form, which can be found online at http:/ /swfrec.ifas.ufl.edu/hlb/. This site also
includes detailed sampling and submission procedures.

In the fight against greening, growers have expressed interest in practices being utilized by McKinnon
Corporation in a grove that has HLB. SWFREC scientists are working to duplicate this program and de-
termine which component parts or combinations are having the apparent effect of .ii.. 1; .. ri..; symptoms
of greening disease. Trials are being conducted by SWFREC citrus horticulturalist Dr. Bob Rouse and
entomologist Dr. Phil Stansly in a grove at the center and in commercial groves.

In addition, grower interest in the possible use of trap crops for psyllid management has spurred testing of
the effects of orange jasmine on psyllid infestations and parasitization in adjacent citrus trees. SWFREC
assistant research professor Dr. Jawwad Qureshi is conducting a trial in which treated and untreated citrus
will be used as controls and movement of the greening bacteria will be monitored in a grove at the center.

SWFREC UPDATE


SWFREC Hosts Groups / Tours

The SWFREC played host to three groups of individuals during the last month.

The Collier County Agricultural Tour kicked things off when 200 participants arrived on four buses to
hear about citrus, peaches, and plums. Their hour-long visit included a citrus demonstration by

ties grown in this area must be of a low-chill
type because southwest Florida does not see the
cold temperatures that, say, Georgia does. The
tour is sponsored by the UF/IFAS Collier
County Extension office and included a number
of agriculture-related stops.

Current irrigation restrictions and their implications on commercial production were hot topics at a
workshop sponsored by UF/IFAS and the Florida Farm Bureau. Among the speakers were citrus
physiologist Dr. Bob Ebel, who spoke about the response of citrus and vegetable crops to drought
stress, and water resources scientist Dr. Sanjay Shukla, who focused on the future of agricultural im-
poundments and the reduction of drought impacts. Plant I." rl-...'. -.r Dr. Pam Roberts also was on
hand to answer grower questions related to drought and commercial production.

The Florida Natural Resources Leadership Institute (FNRLI) staged part of its southwest Florida agri-
cultural tour at the SWFREC. Upwards of twenty-five individuals received a welcome from associate
SWFREC center director Dr. John Dunckelman, who also provided a brief overview of agriculture in
southwest Florida. A panel discussion about farmworker issues concluded the group's visit. The
FNRLI fosters education about a variety of land and water resource issues.


Field Day Spotlights Vegetable Production

Mark your calendars! The UF/IFAS Spring Vegetable Field Day is set for
Thursday, May 1, at the SWFREC, 10am- Ipm.

In-field and indoor presentations will highlight current research underway,
including plant I ., r,, ..1.2. and entomology trials, as well as
an update on the C-139 basin water project. Participants
