The invention relates to biocontrol compositions comprising an entomopathogenic fungus, kits comprising such an entomopathogenic fungus, and methods of using such a fungus and compositions to reduce or kill the population of agricultural, vegetable, or horticultural crop insect pests.

Compositions and methods to reduce insect pests

Pesticidal and/or antimicrobial biological agent-infected arthropod cadavers are formulated by applying a coating agent once on the surface of the cadaver which either (a) prevents the cadavers from sticking together and/or rupturing or (b) acts as an adhesive for a powder or granule applied to the cadaver to prevent sticking and rupturing. The formulated cadavers maintain or improve infectivity, reproducibility, and survivability. The formulated cadavers can be partially desiccated to improve on shelf-life.

Formulated arthropod cadavers for pest suppression

The present invention provides pest control formulations which comprise lignin as well as methods of protecting pest control agents from environmental degradation through the use of lignin. A solubilized lignin solution is prepared by mixing water, lignin, and a pH adjuster to form a solubilized lignin solution having a pH of between about 7 and about 12, preferably between about 8 and about 11, and most preferably between about 9 and about 10. The solubilized lignin solution is then used to prepare the pest control formulation by mixing with pest control agent and a multivalent salt and drying to form a dispersible formulation. The dispersible formulation is mixed with water to form the pest control formulation having resistance to solar degradation. Alternatively, the solubilized lignin solution may be used as an adjuvant by drying and later adding the dried adjuvant to pest control agent and a multivalent salt to form the pest control formulation, or by mixing directly with pest control agent and multivalent salt to form the pest control formulation. When prepared with the lignin adjuvant, the pest control formulation has improved resistance to washoff as well as resistance to solar degradation.
