(Prepared in cooperation with workers of the
Florida Agricultural Experiment Stations)
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 possible, but instead
the effort has been to present the current pertinent
facts on tomato production. Experienced growers may
have several modifications of these practices for their

facts, contact your County Agricultural Agent.

1 lb. per acre
Unstaked: 36" to 40" Produce 1,000 plants-
Staked: 15" to 18" Seedbed, plant acre-
Planted on muck: 6'x6', 8'x8'
FERTILIZATION: (Best results are obtained by ap-
plying fertilizers, before or at time of planting, in
two bands each located 2 to 3 inches below and 3 to 4
inches to the side of the planting row.)

*It is questionable if tomatoes should be planted on mucks.
Manganese is commonly deficient on soils with a pH above
6.0 and may be added as 2% MnO per ton of fertilizer or through
spray applications of 11 to 2 pounds of manganese sulfate per
100 gallons of water. Copper deficiency on muck soils is
counteracted by 1% CuO per ton of fertilizer applied prior to
planting. Copper deficiencies have also been reported on some
of the light sands but are generally held in check by the use of
copper fungicides along with organic chemicals in the disease
control program, or 0.3% CuO per ton of fertilizer.

When late blight is favored by weather conditions,
begin spraying the plants as soon as they have emerged
and repeat at 4- to 7-day intervals until transplanted.
An application just before transplanting is desirable.
Thorough coverage of all above-ground plant-surface
Nabam, zineb and phygon sprays tend to stunt young
plants when used frequently. To avoid this, alternate
the nabam and zineb with phygon and copper A. -
In the southern part of the state and on the West
Coast copper fungicides will not control late blight.
In this area an alternating nabam and phygon schedule
is recommended. In other parts of the state where
late blight is less severe the copper spray may be alter-
nated with nabam.
Do not use an insecticide with phygon, as the mix-
ture may cause injury. Nabam, zineb and forms of
copper that have proved satisfactory are compatible
with the recommended insecticides.
FIELD DISEASES AND CONTROLS:
Excluding phygon, materials and formulas are the
same for seedbed above.
Begin applications immediately after plants have be-
come established and repeat at 4- to 7-day intervals
until end of harvest. Thorough coverage of all above-
ground surface is imperative. Spray is more effective
Nabam is recommended as first choice in the south-
ern part of the state. In the other parts of the state
where late blight is less severe, copper sprays usually
give satisfactory control. In areas and seasons which
are not favorable for late blight, intervals between
applications may be longer. In the southern part of
the state this is a risky venture because with blight
present its spread may become very rapid with the
return of favorable weather.
Materials and formulas same as for late blight above.
Where early blight and late blight occur together, use
the schedule recommended for late blight. In localities
and season where early blight occurs but late blight
is not an important factor, coppers usually give satis-
factory control of early blight.
Gray Leaf Spot
Materials and formulas same as for late blight above.
When late blight is not present applications at 7-day
intervals are usually adequate. Gray leaf spot is not
important in all tomato growing areas or in every year.
When it does occur it causes extensive damage unless
control measures are started on time. If late blight is
also present the schedule recommended for late blight
should be used.
Other than wilt-resistant varieties, no satisfactory
control is known.
