Abstract
Abstract Plots were established on 6 Aug ir flower beds which were located in the median of an urban boulevard. Landmarks were used to delineate plots approximately 6 X 3 ft each prior to treatment. The experimental design was a RCB with four replications. Treatments were applied using hand-held spray bottles at a rate of 3 fl oz of insecticide solution per plot. Thuricide, Pyrethrin, Bioneem, and Naturalis-O were applied weekly after sampling was performed. Sevimol, Talstar and Scimitar were applied twice, first on 6 Aug and again on the 29 Aug. Two different cultivars of petunias were present in the plots, the blue cultivar had an average density of 140 full blooms/yd2 and the pink cultivar had an average density of 235 full blooms/yd2. The number of damaged blooms in the center sq yd of eaci plot was counted weekly throughout the course of the experiment. Bloom damage was reflected in holes in flowers and buds, and/or ragged edges. Eval uation on 14 Aug included damage that was already caused prior to treatment application.
