When using parathion and TEPP take special
precautions not to get the insecticides on any part
the body or to breathe the spray mists, vapors
dusts. Do not use parathion later than two
weeks before harvest.

Sulfur does not control some species of mites.
rathion or TEPP may be used if sulfur is not
fective.

In thrips control, sulfur may be used as the
luent for DDT, thus getting a dual-purpose dust.



DISEASE AND CONTROL

Phomopsis (fruit spots or bottleneck): Use
commended resistant varieties, such as Florida
auty and Florida Market.

Production practices are subject to rapid change
by new problems arising and the application of
research results to meet these needs. No attempt
is made here to foresee all the complications pos-
sible but, instead, to present the current pertinent

facts on eggplant production. Experienced grow-
ers may have several modifications of these prac-
tices for their specific conditions.

For further details on local application of these
facts, contact your County Agricultural Agent.

VARIETIES RECOMMENDED

New varieties are recommended on a trial basis
only.

FLORIDA HIGH BUSH.-A standard variety.
Deep-purple colored fruit.

FORT MYERS MARKET.-A standard variety
similar to Florida High Bush.

FLORIDA MARKET. Phomopsis resistant.
High yielder, but initially a small percentage of
off-color fruit. Of the Ft. Myers Market type,
but a long-shaped fruit.

FLORIDA BEAUTY. Phomopsis resistant.
High yielder, but initially a small percentage of
off-color fruit. As much as 10 days earlier than
Florida Market in North Florida fall plantings and
fruit have a definitely more oval shape.

FERTILIZATION

Best results are obtained by applying half
more of the complete fertilizer at planting ti
and the remainder when the crop is one-third
one-half grown. The initial application should
made in two bands each located 2 or 3 inches
low and 3 inches to the side of the plant r(
Subsequent application should be drilled close
the plant row.

Top-dressing applications of nitrogen or a co
bination of nitrogen and potash vary in amou
and frequency according to seasonal condition
Two to three applications at rates equivalent
100 pounds nitrate of soda and 25 pounds muria
of potash per acre generally meet the needs dt
ing a given growing period.
