To develop a pesticide mixture strategy for managing resistance in Heliothis virescens (F.), several insecticides (chlordimeform, methomyl, sulprofos, permethrin, fenvalerate, cypermethrin, EPN-methyl parathion, and chlorpyrifos) were tested alone or in two- or three-way combinations at full and reduced rates in laboratory and small plott field experiments. While several two- and three-way mixtures (especially chlordimeform-methomyl-permethrin and chlordimeform in combination with several pyrethroids) were as effective at reduced rates as full rates of pyrethroids alone, the residual activity of pyrethroids was often longer than that for the other compounds tested. However, residual activity in the terminal bud region of cotton is reduced as a result of plant growth. This minimizes the effects of differences in pesticide decay rates for insecticides deposited in this region of the plant, the target area for most insecticide applications directed against H. virescens, and supports the role of mixtures in resistance management. Although differences in residual activity were observed for the different insecticides studied, some of the mixtures still showed good potential for control of pyrethroid resistant populations of the tobacco budworm. |
