ARC-Apopka Research Report RH-1979-2 F' r.d.
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was
amended by the Pesticide Law of 1978. This new law allows a wider use of
registered pesticides providing the plant or site is on the label. These
changes are reviewed in the Foliage Digest II(2):3-5, 1979. The pesticide
registration program at ARC-Apopka is developing needed data in support of
registrations and label expansions with special interest toward 24(C) or
special local need registrations that allow uses specifically in Florida.
If these currently necessary chemicals become unavailable, quality pro-
duction of ornamental foliage will suffer with reductions in plant quality
and yield. ARC-Apopka is committed to helping the foliage industry obtain
and maintain these registrations and this report concerns pesticide evalu-
ations carried out from July 1978 to July 1979. Much of the data which
appears in this report was developed through efforts supported by Florida's
Tropical Foliage Plant Industry.
Insecticide, Miticide, and Nematicide Evaluations
The pesticide tests carried out during this 1978-79 period concentrated
on obtaining data for label expansion of presently employed chemicals as well
as to establish labels on new chemicals. The major portion of these evaluations
were in the area of phytotoxicity but with efficacy testing against major pests
for which control data was lacking.
Chemicals were selected for evaluations only if judged by this laboratory
to fulfill a need that is presently not being met and also, only if the chemical
