The patented Beauveria bassiana JW-1 strain of fungus is active as a mechanical (non-chemical) mode of action against major cotton pests including whiteflies (Bemisia tabaci), mites (Tetranychus urticae) and bollworm (Helicoverpa ssp.). Studies indicate that beneficials such as Encarsia spp., Eretmocerus sp., Chrysoperla spp., and others are not impacted by the B. bassiana JW-1 strain.
