Fresh citrus sold in Canada should be treated with only those chemicals
approved by the Canadian Food & Drug Directorate (FDD). The U. S. Environmental
Protection Agency approves 109 pesticides and food additives for use on citrus. Of
these 109 chemicals the Canadian FDD does not approve 80 (their status is "NTE" i.e.
no tolerance established).

The following list of 15 chemicals have NTE status in Canada and are recommended
in "Weed Control Guide for Florida Citrus", "Florida Citrus Spray and Dust Schedule",
or "Postharvest Decay Control Recommendations for Fresh Citrus Fruit".

bromacil paraquat
dichlobenil parathion
difolatan phosphamidon
dimethoate simazine
ferbam terbacil
kelthane (dicofol) trifluralin
lead arsenate trithion

Additionally and of special interest to citrus packers are Benomyl (Benlate),
see Packinghouse Newsletter #42, and 2-aminobutane (2AB), see Packinghouse Newsletter
#55. These are new fungicides not yet recommended for use in Florida that have
NTE status in Canada.

Fruit treated with or fruit from trees treated with any of these chemicals
(plus any of the 63 other NTE chemicals) should not be shipped to Canada. A
measurable residue of a NTE chemical on citrus could result, as it did in June, 1973,
in a warning from the FDD. Seizure of shipments would be the next step and a serious
blow to citrus marketing due to unfavorable publicity.

The horizontal air movement degreening rooms patterned after principles
first published in Packinghouse Newsletter No. 5, July, 1966, are being widely
accepted in the industry. Most new degreening rooms in Florida are built to this
design and many older ones are being converted because they pay dividends with less
degreening time, faster lift truck handling, and better fruit quality. We presently
are aware of 147 horizontal degreening rooms in 31 packinghouses with a capacity of
about 44,000 pallet boxes.

Citrus Red No. 2 (Color-Add) is in very short supply. The lone manufacturer
of this dye, used only to impart a market acceptable color to some oranges, has had
recent lots rejected by the FDA. Rejection was on the basis of harmless, but
unauthorized insolubles in excess of a specified tolerance. The manufacturer is
reported to be reformulating the material to meet Federal standards. If the
reformulation attempt is successful, it would provide less than a year's supply.
Color-add should be used sparingly, only when necessary and at minimal levels,
even after the present crisis is over.

This industry should prepare to survive without color-add. We predict that
one way or another you will lose this dye. Food faddists have attacked it with
mostly false statements (these days a product does not have to be bad to be banned).
Manufacturers are not likely to make a profit because color-add has only one use
and is a small volume dye. Sooner or later you can expect to have to market oranges
without the benefit of color-add.

Elbert Layton, manager of the Florida Tangerine Cooperative, died November 17
at the age of 51. The Tangerine Cooperative has lost a conscientious and hard
working manager. I have lost a valued friend and one of the best cooperators that
we have ever known.

Only too often, our research results go unused because of the difficulty of
translating experimental findings and theory into action on the behalf of the citrus
industry. That this has not been so for the tangerine shippers has been due to the
acumen and effectiveness of this quiet unassuming man.

At one time, the tangerine market would occasionally collapse due to disastrous
"Zebra skin" breakdown. When we came to understand the weather conditions that
were likely to cause this, Elbert and I established a cooperation whereby we would
judge conditions and he would send out bulletins advising when to pick and when not
to. Neither of us liked doing this. The possible reprecussions of an error on our
part were obviously so great that at times we wished that we had never assumed the
responsibility. But it worked, and only due to this conscientious man who knew so
well how to cooperate with scientists, shippers, and merchandizers alike.

He did a good job.

A key word index beginning on the cover of this issue was the useful
suggestion of Jim Ellis, Lake Garfield Citrus Coop., Bartow. Jim has been doing
this with his copies and thought the other readers would find it useful. An
index for all back issues is available on request--see Available Publications.
