Whiteflies in Arizona: sampling, action thresholds & management.

 

Management of Bemisia argentifolii in Arizona depends on 3 key elements: careful monitoring, effective use and timing of insecticides, and avoidance. Avoidance of damaging populations includes a wide variety of cultural controls and best management practices, including variety selection and crop placement; uniform, optimum planting; efficient single fruit set; minimization of crop stress; in-crop and postharvest sanitation in all whitefly host crops; optimization of natural controls; and pest source reduction (often outside of the cotton crop). With these cultural controls in place, reliance on insecticides can be minimized.
