A new biological product for control of major greenhouse pests

The patented Beauveria bassiana JW-1 strain of fungus is active as a mechanical (non-chemical) mode of action against major greenhouse pests including whiteflies, thrips and mites. Studies indicate that beneficials such as Encarsia spp., Eretmocerus sp., Chrysoperia spp.,and others are not impacted by the B. bassiana JW-1 strain. The target pests must come into contact with the fungal spores after direct application, movement on treated surfaces, or bodily contact with other target pests already exposed (horizontal transfer). Application of the flowable formulation can be by electrostatic, air-assist, pulse foggers, injection/water systems, ultra-low volume (ulv) or universal hand equipment. The B. bassiana JW-1 strain can be tank mixed with most pesticides and fertilizers but not with most fungicides. Some identified fungicides are compatible however, a time interval of 48 h before or after application of fungicides Is suggested. Extensive evaluation has yielded no observed phytotoxicity. Toxicological studies indicate that the B. bassiana JW-1 strain does not have an adverse impact on humans, livestock, birds, fish, beneficial insects, crops, waterways, or groundwater resources.
