CONTROL OF INFESTATION BY ARTHROPODS BY APPLICATION OF ENTOMOPATHOGEN AND WAX-CONTAINING PARTICLES Russian patent published in 2016 - IPC A01N63/04 A01N25/08 A01P7/04 C12N1/14 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to application of insecticidal complex particle for control of infestation by arthropods in grain storage places. Complex particle has diameter ≥10 mcm and includes wax particle, which has melting point ≥50°C, and spores of strain of entomopathogenic fungus Beauveria bassiana IMI 398548. Wax particle adheres to cuticle of at least one species of arthropods in granary and has weight, equal from 5 to 95 wt % of complex particle. Fungus spores adhere to hydrophobic wax particles and are capable of development on cuticle of at least one species of arthropods in granary. Also claimed is obtaining and application of dry powder composition, containing said complex particles and, optionally, additional excipients, for control of infestation by arthropods in places for grain storage.

EFFECT: group of inventions provides effective control of number of arthropods in granary Mortality of arthropods constitutes 80-95% on 28-th day after exposure.
