ABSTRACT
The silverleaf whitefly (SLWF), Bemisia argentifolii often interacts between melons, cotton, and vegetables and is particularly difficult to control. Integrated crop management should be considered necessary for SLWF control, but a first step is to develop integrated pest management (IPM) for specific crops; e.g.,cotton. IPM strategies that reduce the likely development of insecticide resistance and help bridge biological with chemical control are desirable. This work investigated two insecticide regimes that included two IGR' s, ApplaudTM and KnackTM. In the first regime, ApplaudTM was applied first early in the SLWF season, followed by KnackTM. Then, non-pyrethoid insecticides somewhat "soft" on beneficials were applied followed by pyrethroids. The second regime began with pyrethroids followed by "soft" insecticides with the two IGR' s applied last. Also, we investigated efficacy of ground application at 15 gal./ac, at two pressures, 40 and 225 psi, using a boom with drops and 5 nozzles per row. The trial was conducted on two contiguous fields of 80 acres total.
