Calibration Rodeo -
For Low Volume
This Calibration Rodeo is a
cooperative effort of the
Florida Citrus Production Research Advisory
Council, FCPRAC), USDA Ag Research Service
(USDA ARS), and the Florida Citrus Extension
With the advent of low volume spraying (Misting)
in citrus, particle size has become important to be
sure the spray mist is: moving around and into
the tree, where the psyllid pest is located, to
maximize contact control, and to comply with low
volume label requirements as to micron size for
low volume spray.
For those who own and are using low volume
sprayers, this is a chance to have your sprayer
evaluated as to its calibration. There is no cost to
you and the information about your sprayer is

Highlands County Extension "E-Talk" Citrus
This newsletter is now only being sent via email
due to the loss of our postage budget in the cut-
backs. Experience is that people will change e-
mail addresses from time to time. When that
happens you need to tell me of the change. All
you need to do is email me at plowbovyufl.edu
and I'll make the change on my mailing list.
If you have someone else working with or for you
who wishes to receive this newsletter, just email
me at plowboyvufl.edu and give me the name,
telephone number, surface mailing address
(optional), and email address.
Additional Newsletter Opportunity
Each of the Florida Citrus Extension Agents
produces a monthly citrus newsletter. Although
some of the topics are the same, yet much is
different. We each approach our newsletters

Certified Pile Burner Class
The Certified Pile Burner Class held August 5
was a success. Everyone in the class passed the
exam at the end of the day and now can
complete their certification.
Citrus growers and others who burn trees or
other brush piles regularly and are certified, can
receive priority to burn even in dry weather, can
burn two hours longer each day, and can get
multiple day authorizations. Non Certified Pile
Burners must use the regular DOF Permit
process and are more limited in how they may
Certification is good for 5 years. Those who use
their certification by requesting a permit to burn 5
times in 5 years will be automatically renewed for
The question is how many people still wish to
become certified. DOF wants me to consider
another class next spring for this area. I need to
hear from you if you are interested in a class to
become certified as a pile burner.
If so, email me at plowboy@,ufl.edu so I can
determine whether to offer another class.
Citrus Leaf Analysis
Sample leaves should be washed and allowed to
dry, placed in a bag that has been labeled and
kept cool until delivered to the lab for analysis.
For more details on leaf sampling refer to the
most current text on citrus nutrition, SL 253,
Nutrition of Florida Citrus Trees. It is on a CD.
Copies are available from my office.
This is the time of year to evaluate the
effectiveness of your citrus nutrition program.
The pressure of the economic times has caused
some to cut expenses where one can and in
some cases that has been in the fertilization
Leaf Analysis is a very precise tool to evaluate
the nutrition status of your trees. This is the
optimum time of year to collect leaves for leaf
Spring flush leaves that are 4 6 months old
from non-fruiting twigs should be collected.
Approximately 100 leaves from 15 20 trees per
sample should be collected from a common area
as to the previous nutrition treatment. If an entire
100 acre block has the same soil type and has
received the same nutritional program then one
sample could cover 100 acres. If there are areas
in the grove that have unique features or have
been treated differently nutritionally, then a
separate sample is warranted. Leaves damaged
by mites or disease should be avoided when
It is a Diffeternt World Out There
The following is an excerpt from the
Chemically Speaking Newsletter.
In these times a bit of humor never hurt.
Excerpt from the Dorset Echo Newspaper Dorset,
"Alcohol-based hand gel is being banned from
entrances at Dorset County (UK) Hospital due to
consumption by local vagrants. Homeless
alcoholics have been spotted drinking the
solution from the dispensers at entrances to the
Dorchester hospital. Two homeless people have
died in London from drinking the gel used to
combat multiple resistant Staphylococcus aureus
(MRSA) and other germs. It will now be removed
from all entrances at the hospital and placed near
supervised wards. The hospital's Infection
Prevention and Control Committee wanted to do
away with the gel which contains up to 70
percent alcohol for health and safety reasons."
