EFFICACY OF BUPROFEZIN FOR WHITEFLY CONTROL IN COTTON, 2008.

The objective of this study was to evaluate the efficacy of buprofezin, buprofezin in combinations with acetamiprid and standard insecticides against sweetpotato whitefly (SWF) on upland cotton under desert growing conditions. Cotton was direct seeded on 20 Mar at the University of California Desert Research and Extension Center, Holtville, CA into single row beds on 40 inch centers. Stand establishment was achieved and maintained thereafter with furrow irrigation. Plots were six beds wide by 50 ft long and bordered by two unplanted beds. Four replications of each treatment were arranged in a RCB design. The applications were made with a Lee Spider Spray Trac operated at 40 psi delivering 42 gpa on 2 Jul, 23 Jul and 6 Aug 2008 through 3 TJ-6
