Treasure Coast Citrus Notes
Scouting for Citrus Greening Fact Sheet
This new publication includes information on when to scout, different scouting methods,
symptoms of citrus greening and what to do when a greening-infected tree is identified.
The current IFAS recommendation is to scout, identify and remove infected trees so as
to remove the inoculum source of the disease, which is spread by the Asian citrus
psyllid vector. Effective management of this disease is difficult, but good management
decisions can only be based on knowing what the greening situation is in your groves.

Dormant Season Asian Citrus Psyllid Control
Results from a trial conducted earlier this year by Jawwad Qureshi and Phil Stansly
indicated that psyllid populations were significantly reduced for 5-6 months following
treatments applied mid-January. Their findings suggest that one or two applications of
broad spectrum insecticides applied before the spring flush could ultimately reduce the
number of pesticide applications required throughout the growing season to effectively
control psyllids. Adult psyllids were fewest at this time and most vulnerable. Avoiding
the necessity of insecticide applications during the bloom period would be very
beneficial to beekeepers who have reported serious losses in the last couple of years.
Additional psyllid sprays later in the season should be based on scouting and made
prior to anticipated growth flushes. It has become quite evident that if you have growth
flushes, the psyllids will come. Insecticide applications for the insect will probably be
more effective in the long term if applications are made before psyllid populations reach
very high levels.

Asian Citrus Psyllids are Spreading!
Florida citrus growers are not alone in having to deal with the Asian citrus psyllid. The
pest was found in the first week of August on residential citrus trees in Alabama,
Georgia, Mississippi and South Carolina. In early September, the psyllid was found in
San Diego County, California, some 11 miles north of the border with Mexico. California
officials are working to delimit the presence of the insect. Good luck with that! Citrus
greening disease (HLB) has not been detected in the psyllids found in these states at

2007-2008 Citrus Budget for the Indian River
Ron Muraro, Extension Citrus Economist had released his citrus production budgets for
the 2007-2008 growing season. It will be no surprise to see that average production
costs increased 19% between the 2006-2007 and 2007-2008 seasons. The high cost of
fuel and energy increased equipment application costs 11% over the 2006-2007
season. Overall increase in chemical prices average 8%. However, fertilizer prices had
the greatest impact on costs in 2007-2008, increasing an average of 80% over 2006-
2007. High demand for plant nutrients throughout the developing world, especially
Brazil, China and India, along with increases in transportation costs were the causes for
the increase in fertilizer costs.
Additional costs were incurred by those growers attempting to manage citrus greening
disease by removing infected trees and controlling the Asian citrus psyllid. Fresh fruit
growers also incurred increased costs while attempting to control citrus canker.

Syngenta Crop Protection 2009 Florida Internship Program
This summer-long internship will allow students to be involved in sales, marketing and
field activities as well as building customer relationships through work with growers,
retailers and manufacturers.
Syngenta currently recruits sophomores and juniors in college, although seniors will be
considered. The candidate should have a background in agriculture and an interest in
pursuing a career in the agricultural industries after college. Interns will be responsible
for a variety of field activities, including scouting, soil sampling and collecting and
analyzing agricultural data. Qualified applicants should be willing to work outdoors and
must have basic familiarity with pest, disease and weed control.
At this time, six intern positions are available, and Syngenta plans to interview
candidates through February 2009. Interns will be placed across various regions of
Florida and must be willing to relocate if necessary.
Interested candidates should fax their resumes to John Taylor, Syngenta Technical
Support Representative at 561-694-7939 or e-mail them to iohn.tavlor(@syngenta.com.

Citrus Pest Management Course, Spring 2009
Citrus Pest Management (PMA 5205, section no. 2563) will be offered for the Spring
2009 term at the Citrus Research and Education Center in Lake Alfred and via polycom
at the Department of Entomology and Nematology in Gainesville. Citrus Pest
Management is graduate level course (3.0 units) for students and citrus industry
personnel working in the area of pest management. Emphasis is given to techniques by
which pest and disease organisms are monitored and how this information is used to
effectively manage pests with the least risk to the environment. The course will be
coordinated by Dr. Larry Duncan, University of Florida/IFAS, Professor of Nematology.
