Merck, Sharp, & Dohme informed us that the allowed residue of thiabendazole
(TBZ) on citrus fruit remains unchanged at 2 ppm. A temporary permit to allow
up to 6 ppm on experimental shipments from California and Arizona has been
granted. These tests are necessary before an increase in the residue tolerance
can be granted. The information from Merck and related at the March 31 Fresh
Citrus Shippers Association meeting that the TBZ residue tolerance had been
changed to 6 ppm was erroneous.

Note: It is suggested that this Newsletter will be of value to citrus
sales managers who will be doing business with the buyers who attended this school.

Origin. The Supermarket Institute, 200 E. Ontario Street, Chicago, Illinois
60611, has instituted a series of schools for Produce Buyers to help improve the
quality and volume of fresh produce handled in their stores. This was the fifth
such school and the second held in Florida. Over 40 produce buyers from all over
the United States attended. It started with lectures in Gainesville and
traveled for a week down the length of Florida, visiting packinghouses and
production areas, pausing for demonstrations, exhibits, and discussions. The
program included participation by IFAS, University of Florida (Cooperative
Extension Service, Vegetable Crops Department and the Agricultural Research and
Education Center, Lake Alfred); officials of the USDA, Washington D.C.; USDA,
Orlandol Florida Department of Citrus; Florida Department of Agriculture; and
many from industry. Obviously, we do not have enough space to give all the
details of this school; but the highlights of particular interest to the citrus
industry are mentioned.

For the produce buyers, the highlights of the trip were probably the visits
to producing areas. They picked 'Valencias,' swallowed black dust in windy
celery fields, shivered in vegetable precooling rooms, and generally learned a
great deal of the problems of the grower and shipper.

For readers of this Newsletter, the highlight would undoubtedly be the
joint meeting with the Florida Fresh Citrus Shippers Association and Produce
Buyers' School at Lake Alfred. Notes of the discussion at this meeting are listed
as available at the end of this Newsletter.

Main Problems. High packs of all produce was the most consistent problem
mentioned by the produce buyers. Many complaints of crushed fruit in bags or
square fruit in cartons or Bruce box packs due to overfilling were noted. By
far, the greatest number of complaints related to grapefruit in poly bags and

Grading (sorting) and sizing were also spotlighted as weak areas for citrus.
Several buyers pointed out that bagged apples are now received in better condi-
tion with a single tier of upright bags in cell-type bagmasters rather than
jumbled or horizontal bags. These buyers repeatedly suggested that this approach
be tested for citrus.

In every type of produce, there were marked discrepancies between what the
buyer said the seller would supply and what the seller said the buyer wanted.
Eyeball to eyeball, they all want what is good for the produce if the costs are
not excessive. Who should pay for even modest increases in costs was seldom
agreed upon. About the only point in which there seemed to be universal agree-
ment was that palletized loads should be on a 48" by 40" base.

Decay Control and Quality Control. Since the last Florida Produce Buyers'
School in 1967, there seems to be a better understanding of the role of fungi-
cides in citrus decay. The produce buyers related no experiences with irate
customers because of pesticides or pesticide declarations accompanying their
produce. In one case, the buyer mentioned having residue analyses for citrus
fungicides done by an independent laboratory. In this case, they were attempting
to evaluate if enough of the labeled fungicides were present for effective decay
control. Opinions varied on the role of the buyer in requesting a specific
fungicide on citrus and other produce.

There was considerable discussion as to who should accept responsibility
for correct loading, including stacking patterns and bracing of the load.

The produce buyers attending this school would like to be able to request
a certain degree of precooling, expressed as pulp temperature, and to be sure
of getting it. A suggested method would be to record this information on the
bill of lading. This method would require a uniform, mutually understood, tech-
nique of measuring pulp temperature, preferably by a third party such as the
Federal-State inspector found at each citrus packinghouse.

Value of the School. There were many direct contacts which were valuable.
There were also numerous suggestions as to how to improve our product which is
of great value. The produce buyers discovered that 'Valencias' carry two crops
at the same time and also that some citrus trees have thorns which are among some
of our problems they observed first hand. All of these items have definite value
to us and to the produce buyers. However, the most valuable lesson of the week-
long school is that communication between produce buyers and citrus shippers can
be achieved through their respective organizations, the Supermarket Institute and
Florida Fresh Citrus Shippers Association. Not only are the means available for
a dialogue, but also an organization such as the Supermarket Institute can express
an opinion for a large number of buyers with an impressive share of the market.

Further Information. We were repeatedly asked for information that is readily
available in publications from various sources. In all cases, we promised that
we would list such sources of information in this Newsletter. For this reason,
the usual list of available publications is much longer than usual and includes
some publications that have been listed before as well as sources of statistical
information routinely issued by both government and private sources.
