Four hundred and fifty years ago, Francis Bacon said, "Knowledge is power;"
but he did not have to cope with the complexities of modern legislation! Some
of the most complex legislation currently affecting the citrus industry is that
concerned with the use of necessary chemicals for the production and marketing
of the crop. To a certain extent, we in agricultural research and extension in
both State and Federal Service have some degree of knowledge with regard to these
matters. But we have absolutely no power, nor should be have any. Nevertheless,
our phones ring constantly and we are called upon for advice, articles, or talks
on matters relating to pesticide clearances. This is quite in order when'advice
is needed on the use of chemicals already cleared and having residue tolerances
not likely to be changed. This, however, is hindsight; and foresight is going
to be very much needed if the Florida citrus industry is to benefit from modern

New chemicals are developed, not by research agencies, but by commercial
companies and at enormous expense. Agencies, such as our own, test them on indi-
vidual crops and for particular usages. Then if they offer some clear-cut advan-
tage over methods in current use, we work with the companies to obtain legal
clearance. This has never been simple and was always costly, but it has now
become extremely complicated and very expensive indeed. Even the most innocuous
of chemicals may need expenditure of several million dollars to get clearance for
use on a food product. These expenses can only be undertaken by companies who
expect to get their investment back from sales. Doing so involves having some
degree of exclusive marketing, usually through a production or use patent. With
the intense pressure towards biological, rather than chemical materials, new pest
control methods are becoming available that depend on mass production of "friendly"
disease agents. Examples would be the production of spores of a fungus which
destroys caterpillars on cabbages and similar crops or of a virus that kills the
boll worm that destroys cotton. We are told that probably neither of these are
patentable. Many other such methods may be developed if some means can be found
to finance them, either by supporting research or by guaranteeing a market for
whomever does so.

Another aspect that is very serious is that many companies are getting out
of the business of producing agricultural pesticides because they can invest
their money more profitably elsewhere. We have had a vivid example recently in
which we lost several years research. The manufacturer had obtained a temporary
tolerance for residues of 2-aminobutane. We developed a fungicidal fumigation
method using "2-AB" suitable for treating packed fruit after loading in trucks,
trains, or ships, with decay control treatment taking place on the way to market.
The manufacturers, however, could see little chance of recouping their investment
and dropped the tolerance request entirely. We could not blame them, though the
results of our research are now useless. This is a story that is going to be
repeated many times unless something is done.

Newsletter No. 41

And who is to fight back the next time a necessary tolerance is unjustifiably
bushwacked by a pack of conservationists?

The citrus industry needs to set up an office to handle all matters of
obtaining, modifying, or defending pesticide clearances for Florida citrus,
whenever this cannot be handled by State or Federal employees. This should not
just be a committee. This must be an office with money to spend and power to
speak for the industry as such. What shape or form this should take or what
organizations should be involved I do not know. It is probably not up to me to
suggest. The need is there and, if not fulfilled, will eventually prove costly
for every grower, shipper, and processor of citrus fruits in Florida.

The meeting with the above title is -affectionately known.locally as the
"Perishables Conference" and is designed for shippers, carriers, and receivers.
The program is listed in available publications in this Newsletter.

This Conference will feature new technology and the utilization of more
effective methods to deliver quality perishables. The fundamentals of quality main-
tenance during marketing for Fresh Fruits and Vegetables, Fresh Meat and Poultry,
Flowers and Foliage Plants, and Frozen Foods will be covered in separate concurrent
commodity sessions. The objective of the program is to bring about greater appre-
ciation for responsibility, standardization, and communications among the handlers
of perishable products. If the planning session with industry leaders is any
indication, the discussion sessions will allow-no one to sleep.






will attend the Conference on "Delivering Quality Perishables -
Streamlining Team Efforts in the '70's," (A Conference for Dr. James Soule
Shippers, Carriers, and Receivers), January 9-11, 1972. Please 1179 McCarty Hall
enclose a $45.00 check payable to the Florida Cooperative University of Florida
Extension Service for registration fees and mail to: Gainesville, Florida 32601

A limited amount of free exhibit space is available at the conference on "Delivering
Quality Perishables--Streamlining Team Efforts in the 70's" on a first-come first-
serve basis.
