And the biological effectiveness of the entomopathogenic suspension of Bacillus thuringiensis in the control of first-third instar larvae in the variant with FP-09 in combating Leptinotarsa decemlineata larvae was 6.8%. On the potato lots where a solution of the entomopathogenic bacteria Bacillus thuringiensis, FP-09 was used, several entomophages were observed.roBacillus thuringiensis sp. thuringiensisinsecticidal activityplant protectionsArticlehttps://doi.org/10.53040/gppb8.2024.133
