Tomato cultivar and transplanting date were: Agriset 6153, 21 February 2001 for Spring 2001; Agriset 6153,12 September 2001 for Fall 2001; and Florida 91, 19 February 2002 for Spring 2002. Weekly applications of foliar sprays were initiated seven days after transplanting and were continued until seven days before the final harvest.Treatments were applied using a hand-held, 11.3-L garden sprayer at approximately 10.3-KPa pressure with thorough wetting of foliage to run-off. The design for all experiments was a randomized complete block with four replications of each treatment.
