Interpretive Summary:

Technical Abstract: Nine upland cotton cultivars were evaluated in the field for susceptibility to silverleaf whitefly, Bemisia argentifolii Bellows and Perring, in Imperial Valley, CA in 1995 and 1996. All cultivars were susceptible. Using 4.1 adults per leaf turn as an insecticide-treatment action threshold, Deltapine (DPL) 5409 and 5415 required 5.5 applications of insecticide, DPL 50, 5461, and 5517 required 6 applications, DPL 5432 and 5690 required 6.5 applications, Louisiana (LA) 887 required 7 applications, and Stoneville (ST) 474 required 7.5 applications. Results indicate the potential to reduce insecticide application by selecting appropriate cultivars that are commercially available.
