FIELD: agriculture; forestry; insect pest control. SUBSTANCE: method involves the production of biomass by the method of deep cultivation of Bacillus thuringensis and isolation of active fraction from the biomass followed by drying and mixing with filling and adhesive agents. Prior to drying the active fraction is mixed with some solvent and kept until the active matter is dissolved. The sediment is removed, and the solvents are alkalis such as sodium or potassium hydroxides (the ratio of volumes is 1:4- 1:5). Prior to drying the solution is supplemented with some adhesive agent, for instance casein glue. The rate of supplementation is 2-5%. EFFECT: higher insecticidal activity. 2 cl, 3 tbl
