"IFAS Guidance for Huanglongbing (Greening) Management"
The UF/IFAS Citrus Research/Extension Team has brought together a plethora of information,
based on current research, on the current position of UF/IFAS on management of Citrus
This "Guidance Document" is a guide containing options using the current IFAS position on
management of HLB to aid you in decision making.
Print it off and when you have time, read it, and set it aside for a while, then read it again. It does
not make decisions for you, but it should give you direction and help you with "guidance" as you
try to cope with this pest.
This document is dynamic and will be modified as research lends to future improvements.
Florida Citrus Agents Survey
The Florida Extension Citrus Agents work cooperatively on educational programs. We need to
survey these who participate in our programs to: 1). effectively evaluate the relevance of
programs, 2). to determine how participants utilize the information received, and 3). to respond to
funding sources for our programs such as grants and sponsors.
If you attended the Florida Citrus Grower Institute Symposium last Spring (April 2009) in Bartow,
or one of the Fall 2009 Low Volume Technology Workshops in one of the six locations, would you
take four minutes and complete the survey at the following computer link:
Florida Citrus Industry Coordinating Council Annual Report
The FCIRCC has issued its Annual Report for 2009. The council annually establishes research
priorities based on input from all segments of the industry. Attached is a copy of the report
summary. If you want to see the full report, go to www.fcircc.orq.
2011 Youth Citrus Project
The 2010 Youth Citrus project was very successful with 32 young
people growing citrus trees and displaying them at the fair. The
objective of creating more awareness and understanding of citrus
and the Highlands Citrus industry by these young people was met.
We are now taking applications for the 2011 Youth Citrus Project.
This project is open to all youth including 4-H & FFA members between the ages of 8 andl8.
Also, they must be in the 3rd-12th grade for the 2010-2011 school year.
Attached is a flier announcing the 2010 program.
If you know of some young person who should consider entering this project have them contact
me at (863) 402-6540 or plowboyvufl.edu and I will get them a registration form.
Registration forms are due by April 16, 2010 to the Highlands County Extension Office, 4509
George Blvd., Sebring, FL, 33875.
Participants must attend the First Workshop Youth Citrus Program Workshop Thursday evening
April 22nd, 2010 6pm-7:30pm at the Bert J. Harris Agricultural Center.

Citrus Flower Bud Induction Advisory
Dr. Gene Albrigo during the fall and spring issues regular Flower Bud Induction Advisories based
on weather related parameters. It is an excellent tool to predict flower bud initiation. This year has
been one of those years where the use of this tool is magnified because of long periods of cool
Some pinfeather flush and bud break has been observed; however, it has been slowed
dramatically due to recent cold temperatures.
One of the biggest spin-offs of this advisory is the aid in planning sprays that relate to bloom
period as we attempt to control psyllids while and avoid applications during high bee activity.
The current advisory (March 5, 2010 is as follows:
FLOWER BUD INDUCTION ADVISORY #11 for 2009-2010-03/05/10
Current status for 2009-10 Bloom -Due to the cool weather, predicted full
bloom dates have been pushed back about one week in central and
northern areas and 3 or 4 days later in southern areas. The predicted full
bloom dates are 19-21 March in southern areas, 25 to 27 March in central
areas, and 29 to 30 March in northern areas. These dates may be pushed
back one or two more days from the cold weather predicted into this week
end. The warmer weather next week should advance bud growth and full
bloom will come quickly if warm weather continues after next week.
In central Florida daytimes highs are projected to be above 70 degrees F through Sunday, March
Although a single intense bloom should be the norm, some blocks have little bud push while others
have buds out 2 cm with the flowers clearly visible. This situation exists in Valencia blocks from
Lake Alfred to Lake Placid and perhaps in all districts. A scattering of inflorescences have been
observed that were near full bloom, but no healthy trees were seen with a general full bloom. With
the induction levels experienced this year, I expect that most buds will produce more than one
flower. Most buds appear to have leaves as well as flowers, necessary for good fruit set.
Unless unusual weather occurs, I will update these reports in two weeks, about March 19th.
If you have further questions, please contact me (albrigoaufl.edu).
