IFAS Extension

Well 2009 is shaping up to be a very interesting year. First we had two hard freezes, then a prolonged drought
followed by 20+ inches of rain in two and half week period. Now that we are headed into the heart of hurri-
cane season, lets hope that the weather treats us all a little better. It seems fruit prices have been creeping up a
little of late as well, which is vital in our efforts to manage pest and diseases in Florida citrus production. I
encourage you to keep up a good fertilization program to promote tree health and to maximize your fruit pro-
duction. Your grove is an investment and you want to make sure to keep trees healthy so that you have plenty
of fruit when prices come back up. I encourage you to make sure you are taking and sending in leaf tissue
samples for analysis so that you know what types and how much nutrients that your trees require.

Don't forget summer is a great time to relax and go to the beach with your family!

Interesting early results from greening related research projects.
I am always trying to write something I feel is of value to growers to help them with current problems. Of
course greening and controlling its vector the Asian citrus psyllid has been the number one issue on most peo-
ples minds. As we learn more and more, thoughts and ideas begin to clarify or take on more relevance. Two
research projects that I have found interesting of late are based on nutrition and production systems. The first
is Dr. Bob Rouse's experiment looking at the components of what has been referred to as the "Boyd program".
Maury Boyd has been using a cocktail of nutritional and systemic acquired resistance products (SAR) on one
of McKinnon Corporation's groves in Felda for the past 4 years. Many people have visited the grove, our ex-
tension program has been twice and I have gone an additional two times. The infected trees seem to be pro-
ductive even though they have had the disease for sometime. Will the grove eventually quit producing fruit
and crash? Most likely, but no one knows for sure. However, so far the observations have been positive. One
of the major issues of implementing the "Boyd program" has been the cost of materials.
Dr. Rouse recently presented some of his early observation from an experiment based on the Boyd pro-
gram. I personally have had the opportunity to view the progress of the trees in these experiments (in the field)
and the results look promising. Below is a picture of two trees that were confirmed positive for greening via
PCR and are located in Dr. Rouse's trial (all
..r.. trees in the study are greening positive). The
top pictures of trees 6-25 and 6-26 were
take, n in December 2007 the bottom pictures
are of the same trees taken in December
2008. All of the trees receive "typical" citrus
Production fertilization and irrigation. How-
i H oe.ul info ationgl e :e:-u t' e i e 6-25 w as supplem ented w ith the com -
Sponents of the "Boyd program" while the 6-
2_ received just the standard irrigation and
h. cl:eurnr b s th u t'etilizer. Tree 6-26 looks as we expect a
g rleening infected tree to look, while 6-25 has
flushed with new leaves and even has set
fruit this past season 2009. Dr. Rouse has
seen this type of response in multiple trees as
the treatment has been replicated. Dr. Rouse
is collecting data on number of flush, length
of" flush, number of set fruit, etc. as part of

this trial. Those data are not yet available; but I think so
far it passes the "eye test", that is something seems to be
working. Hopefully, information gleaned through this
trial will help eliminate some of the products and lessen
the cost. Will nutrition be the ultimate answer to green-
ing? Probably not, but if we can at least keep the trees
productive for a longer period of time, we in the citrus in- W
dustry allow ourselves more time for permanent solutions
to be developed. It should be noted that a major compo-
nent of the "Boyd program" is intensive psyllid control.
Researchers feel that psyllid control is important to lessen
the effects of greening even when using the "Boyd pro- .

gram" this theory currently being tested by Drs. Rouse and Stansly in the Immokalee area.
Another set of early results that I have found interesting comes from Drs. Schumann, Morgan and Sy-
vertsen's work on the Advanced Citrus Production Systems (ACPS). Recently, a website was added to de-
scribe the purpose and scope of this work it can be found at Pulse drip fertigation Ridge or by looking under Aer 9 moh In o ar ,tPSee r,,at.~ -id
the research section of the CREC's homepage. The objective A"'""ga '""'c""p~""r r
of ACPS is "Intensively managed citrus production systems for ,' rS
early high yields and vegetative flush control in the presence of ,
greening and canker diseases". The ACPS takes advantage of
new technologies to control irrigation and fertilization in a
more precise manner. These techniques have been used suc-
cessively in other parts of the world but have yet to be proven
in Florida climatic conditions.

Water applied to mature trees -Ridge Early results
look promis-
Convenional ET-based MS (100%) ing for in-
creasing production per acre. I personally feel this will be
necessary for future citrus production due to the increased
Cost of production in the face of current and future disease
Sand pest pressures. The greatest gains in yield and quality
were achieved with the pulsed drip system. An additional
Senso-based MS (40%) added benefit of this system was a water savings of 71%. As
f/ Sensor-baseddrip (29%) you are aware water use in Florida is increasing with an in-
crease in the state's population. Technology that produces
more fruit, with better quality, while using less water seems
u.t. ; .. like a winner (see graphs -Mg ha is approximately equiva-
lent to box/acre i.e. 50 Mg/ha = 500 boxes/acre). Another
result was the more efficient use of fertilizer for growing young trees. The ACPS system used 13% than that
of the conventional method used by the owner of the grove when comparing ACPS to historical program.
With fertilizer prices having risen over the past two years, this represents significant cost savings. I encourage
you to look at the ACPS website for more information.

Leaf and soil sampling for increasing tree health and profits

This past year saw dramatic increases in fertilizer prices. Fertilizer represents a large percent-
age of a citrus production budget. One of the best practices that you can implement to maximize
productivity and minimize expenses is taking a leaf tissue sample. I am surprised by the number
of growers that I meet that do not take leaf samples annually. Tissue analysis are very inexpen-
sive and can lead to a more effective fertilization program which can save you money.

Leaf tissue samples provide information about citrus nutrition, it is particularly effective for 1)
macronutrients, primarily nitrogen (N) and potassium (K), that readily move with soil water, and
2) the micronutrients copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe). Leaf tissue sam-
pling should be done yearly so that you can monitor the changes in nutritional status over a pe-
riod of several years.

Leaf sampling should be done in management blocks no greater than 20 acres. The grove
should be sampled to minimize any differences in soil or tree health. The best time to take tissue
samples is in the month of August. A typical sample should consist of approximately 100 leaves
taken from 6-8 month spring flush leaves that are not on fruiting twigs. Typically samples should
be taken from 15-20 trees distributed in different areas of the block. Trees should be the same
variety and rootstock.

If you have made a copper spray or micro-nutritional spray prior to sampling, be sure to wash
leaves with deionized water prior to sending in for analysis. Small amounts of micro nutrients
residuals can have large effects on you results. Also, you do not want to send the leaves wet,
drying them before shipping is recommended.

Soil sampling in
TaMle 46. Adjultidng a citrus ertilizaon program based on leai risue mnrli,

Florida should be
done in August
as well. Leaf
sampling and soil
sampling can be
collected at the
same time. Soil
samples should
be taken within
the tree row, in
an area that is
being wetted by
the micro sprin-
kler. Soil cores
should be taken
8 inches deep.

Soil samples should be taken from 15-20 trees in an block (these should be the same trees that
you leaf samples were taken from). Again you want to work in blocks less than twenty acres in
size with fairly uniform soils. Soil samples should be air dried before shipping. Soil and tissue
samples can be sent to the University of Florida's soil laboratories which can be accessed at
http://soilslab.ifas.ufl.edu/pdf% 20files/ProducerCitrus.pdf. If you were to send in both soil
and tissue samples the total cost would be $27.00.

Soil and leaf analysis checklist:

* Leaf tissue analysis is valuable for all elements
* Soil analysis is valuable for pH, Ca, P, Mg and Cu.
* Be aware of residuals on leaf surfaces, try to avoid collecting samples from recently sprayed groves
* A sampling program that is conducted annually will be the most successful.
* Leaf and soil analysis interpretations should be used to make fertilization decisions. Wise use of these re-
sults will allow for optimal yield and savings.

Thanks to All of You who support the 4H Citrus Tree project!

We had over 150 4-H youth participate in the Citrus Tree
Project this past year. The kids learn about the impor-
tance of Florida citrus production. In addition, the kids
learn about different citrus varieties, rootstocks, pests and
diseases. Also, the kids grow a citrus tree over a course of
the year, which are judged and the top 30 are auctioned at
the fair. Events included a field day at the Mid Florida
Citrus Foundation A.H. Krezdorn grove where youth get
to learn about citrus production and pick some fruit (funny
there is always a big turnout by parents as well). The 4-H
youth work on project books and take a knowledge test as
well. There is the Jim Yates horticulturist award ($500)
which is given to the best overall participant. Juniors and
Seniors in high school that have participated in the 4-H
Citrus Tree Project also are eligible for the John Jackson
scholarship to help with college expenses. This is a great
project to educate our youth. It would not be possible
without the growers who volunteer their time and donate
money to help fund the project. I would specially like to
thank Bill Lennon, Mickey Page, Wade Beck, Ben Krup-
ski, James Strong, Doug Raymond, Jamie Yates and Mar-
tha Yates for their help!! For more info go to our website
