Harvesting and Handling Section



2-Aminobutane (sec-butylamine, 2-AB) was approved July 7, 1972, as a postharvest
fungicide for citrus fruit with a tolerance of 30 ppm. The phosphate salt of
2-aminobutane is being used in California. This fungicide is particularly effective
for control of citrus molds, but of less value for control of stem-end rot fungi.
In California, where stem-end rot is not a problem, 1% 2-AB is commonly flooded
over fruit in pallet boxes as it is delivered to the packinghouse. This process
is known as "bin drenching". To be effective, 2-AB must be left on the fruit
surface. This fungicide is soluble in water and leaves no visible residue. No
peel injury due to the use of 2-AB as a flood treatment has been observed.

2-AB controls molds that have developed resistance to TBZ and Benlate. While
molds' resistance to these fungicides have not been observed commercially in Florida,
resistance has been a problem in some storage rooms in California and in experimental
work in Florida.

Labeling.--The preferred name for labeling purposes is sec-butylamine. Cartons
containing fruit treated with this fungicide must be labeled. A label could read,
"Sec-butylamine used for decay control."

Recommendations for the use of 2-AB have not been worked out .or Florida, bt
a 1% recovery flood over fruit in pallet boxes (bin drenching) before degreening
may be commercially practical on fruit with high decay potential. Treating lemons
before "cool coloring" at 600F may also be a use for this fungicide in Florida.
When more information on the use of 2-AB is available, it will be included in a
copy of the Packinghouse Newsletter.

An Extension Circular, Postharvest Decay Control Recommendations for Florida
Fresh Citrus Fruit (see Available Publications), gives the latest decay control
recommendations for Florida.

Any time I am in a packinghouse office, I usually see a clip board with.the
current marketing bulletin quoting prices typically in the region of $2.50 a carton
for oranges and (how times do change') even more for some sizes and grades of
grapefruit. Step into the Sales Manager's office and the phones are buzzing
with quotations of as high as $5.00 per carton on Murcott honey tangerines. I
find myself thinking that all these quotes in air conditioned offices and on the busy
WATS lines depend on the probability that someone, somewhere, sometime, will pick
the fruit from the tree to start all the industry's wheels into motion.

My mind keeps going back to the "hand" which must first pick the fruit. I
begin to think more about this "key" individual involved in this sequence-of-events.

What is his profile? -- What is his age? How long has he been doing this
type of work? His productivity? How many more years will he continue? Who will
be his replacement? His future track record?*

Giving serious thought to some of the hard facts in labor recruitment, we

1) Our affluent society and overall general business climate has now created
a situation of "Jobs looking for people" rather than that of people looking
for jobs. This situation can readily be verified by looking at the "help wanted"
signs hung out all over the countryside. It is a worker's market. Some employers
have given up looking for workers and are willing to hire just warm bodies! But
where are younger pickers coming from as the old ones go?

2) The old bug-a-boo about being a school "drop out" has lost a lot of its
former stigma. The woods are full of eager and willing "Let us train-you-for-a-
job Agencies".

3) For a few athletic youngsters, there is the professional sports arena.
Opportunities for the gifted athlete which make a college President's salary look
like a bag boy's tip'

4) Hovering in the background are recruiters for the armed forces. They offer
paid bonuses in advance, month-long paid vacations, free medical and dental care,
get paid while-you-learn-a-trade, 20-year retirement plans, and all other kinds of

The person actively involved in recruiting harvesting labor is keenly aware of
these and many more competing factors. Increasingly, he is going to need all the
help the industry can give him.

The demand for workers in construction, sanitation services, landscape field,
building maintenance, etc. is constantly increasing and our industry must compete
with these groups in the recruitment of labor.

All this is just the tip of the iceberg as we look down the road and ask:
Where will industry recruit tomorrow's labor force, either in terms of hand pickers,
or in terms of skilled mechanics and machine operators to maintain and operate the
harvesting machines we hope to get for all the money we are spending?
