'Florida Market' eggplant was transplanted on October 17, 1984,
into Myakka fine sand on the University of Florida's Central Florida
Research and Education Center in Sanford. A plot consisted of one 20'
row with 12" plant spacing. Each plot was separated by two unplanted
rows; row spacing was 30'. Treatments were replicated in four
randomized complete blocks separated by 25' weed-free alleys. Spray was
applied by hand with a C02-pressurized sprayer. Three nozzles (D3-25)
were used per row; one overhead and one drop on each side. The delivery
rate was 50 gpa with a boom pressure of about 40 psi and a speed of 2
mph. Aphid precounts were taken on one leaf on each of five plants in
the middle of each plot on December 14. The leaves were marked with a
hole-punch so postcounts could be taken on the same leaves. Spray was
applied on December 16. Postcounts were taken 24 and 48 hr later.

The results are presented in the table as % reduction per five
plants. The level of infestation was considered heavy. The pestiferous
species present was the green peach aphid, Mvzus persicae (Sulzer).
Both Baythroid and Pydrin gave acceptable control. No phytotoxicity was
