EVALUATION OF INSECTICIDE EFFICACY AGAINST WHITEFLY IN BROCCOLI, 2006

The objective of the study was to evaluate the efficacy of new and standard insecticides against sweetpotato whitefly (SPW) on broccoli under desert growing conditions. Broccoli was direct seeded on 18 Sep 2006 at the University of California Desert Research and Extension Center, Holtville, CA into double row beds on 40 inch centers. Stand establishment was achieved using overhead sprinkler irrigation, with furrow irrigation used thereafter. Plots were four beds wide by 50 ft long and bordered by two untreated beds. Five replications of each treatment were arranged in a RCB design. Formulations and rates for each compound are provided in the tables. Soil injections mixtures were applied 2 inches below the seed line on 18 Sep at 31 gpa. Foliar spray applications were delivered to the lettuce through 3 TJ-6
