This article investigates the biological efficacy of biopreparations based on Bacillus thuringiensis and Trichoderma lignorum
against the larvae of Agrotis segetum, one of the dangerous pests of agricultural crops. According to the results of laboratory
experiments, the combined preparation based on these microorganisms exhibited high entomocidal activity and caused 100%
mortality of the larvae within a short period. The results indicate a synergistic effect of the biopreparations and confirm the
prospects for their application as an environmentally safe biological plant protection agent.
