PACKINGHOUSE NEWSLETTER

PEEL INJURY OF ORANGES

IMPORTANT WARNING

Dow-hex, or any other Dowicide formulation used as a wash, flood or dip MUST be
throughly rinsed from the fruit before any other packinghouse treatment. Do not
worry about the possibility of over-rinsing. This fungicide forms an insoluble
precipitate in the cracks, plugs, and minute scratches where it is needed.

It is particularly important that the contamination of the color-add emulsion with
Dowicide should be at a minimum. The color-add emulsion and o-phenylphenol (Dowicide) are
not compatible. When the fungicide applicator is in the packing line just before the
color-add tank, the rinse must be efficient. Three rows of wide angle nozzles on
staggered centers are not excessive.

We hope that frozen fruit separators are not needed this season. But if they are,
be careful not to get Dowicide into an oil emulsion separator. There is no danger with
water-type separators.

PLEASE NOTE: This is not a change in the recommended Dow-hex procedure. This
only emphasizes the importance of the instruction to rinse properly. A number of
packinghouses who have followed the recommended procedures for 10 years have not
encountered any trouble at all--but they have good rinses.

PACKINGHOUSE MODERNIZATION

GUIDELINES FOR AMOUNT OF INVESTMENT FOR EQUIPMENT CHANGESI/

A vital part of the management function of a citrus firm, as with virtually
all kinds of enterprises, is the continuing appraisal of a variety of situations
in which present equipment may be replaced with more modern units. Decisions must
come sooner or later. Always interwoven in the decision-making is the familiar
question "will it pay?"

A detailed cost comparison for two or more alternatives is usually laborious
and time consuming. Thus, a quickly accessible guideline with some sacrifice in
accuracy, can be useful. In some cases, by preliminary use of such guidelines,
it would be possible to eliminate some alternatives and give all attention to a
thorough comparison of those left after the first "screening."

Given reasonably accurate labor savings per year, for example, management
may have easy-to-use guidelines which are based upon capital recovery formulas. The
information is presented in table form so that, for various interest rates and periods
of time, management may see an amount which, in a screening stage, can be considered
justifiable investment for the estimated savings from a possible change.

It must always be remembered that the formulas do not taken into account any
expenses except depreciation and interest on the investment. Therefore, before
final steps are taken, the net savings for given alternatives need to be calculated
and comparisons made. In this, all significant items of operating and maintenance
expense should be considered as well as taxes and insurance.
