BIOINSECTICIDE COMPOSITION FOR PROTECTION OF CROPS FROM SOIL PESTS Russian patent published in 2023 - IPC A01N63/23 A01N63/30 C05F11/08 

FIELD: agriculture and biotechnology.

SUBSTANCE: bioinsecticide composition comprises a solid carrier material and a biological component. As a solid carrier material, a mixture of vermiculite with brewer's grains or brewer's grains is used, and as a biological component, immobilized biomass of a bacterial-fungal complex is used, which includes the biomass of micromycete Beauveria bassiana F-1357 in combination with bacteria Bacillus thuringiensis B-6335 or actinobacteria Pseudonocardia carboxydivorans AC-2046, taken at a ratio of 1:1-3 by volume from the biomass of fungi and biomass of bacteria for subsequent immobilization on the carrier material and content with a concentration of at least 1×10⁷ CFU in 1 g of the composition, in the following ratio of components, wt. %: carrier material 80-90; biomass of the bacterial-fungal complex 1-5; moisture is the rest. A mixture of vermiculite and brewer's grains is taken at a volume ratio of 1:3.

EFFECT: reduction of populations of harmful soil-living insects in the stage of adults or larvae and increased plant productivity.
