Abstract

Our research examined the insecticidal activity of the biopreparation "Bioturin" developed on the basis of the bacterium Bacillus thuringiensis to protect agricultural crops from pests. When testing the biopreparation against the cotton bollworm on cotton, the insecticidal activity on the 14th day showed 81.4%, and in relation to the Colorado potato beetle, the insecticidal activity was 81.5%.
