The article presents the results of a study of the biological effectiveness of 2 biological drugs in the Leningrad region. This is a biological product Iriard, L. based on Streptomyces loidenis strain P-56 - against wireworms and a drug based on the strain - Streptomyces sp. 0952 (hereinafter referred to as 0952). Strains for new biological products were discovered by colleagues as a result of multi-stage screening based on entomocidal and antifeedant activity. Monoclonal isolates were isolated, based on of which samples of the cultural liquid were formed. In 2022-2023, employees of the FGBI VIZR conducted laboratory and finely differentiated field experiments on the effectiveness of laboratory new samples of biological products based on actinomycetes of the Streptomyces type. The experiments are aimed at expanding the insufficient range of new biological products for protection against the most dangerous pests for this crop: wireworms and the Colorado potato beetle. Application of the drug of Iriard, L. was presented for processing the tubers of the «Nevsky» tubers before planting. Based on the field assessment, it was established that the biological product Iriard, L. reduces the number of wireworms increased, since the number of intact tubers was twice as large as in the control. Another drug based on strain 0952 demonstrated the same biological effectiveness against younger Colorado potato beetle larvae. As a result of treatment of these variants with a biological preparation, 80% - 92% of larvae of 1-2 instars died after 5 days. The dependence of entomocidal and antifidant activity on the concentration of the drug has been established. The use of research drugs to protect against these harmful factors has been experimentally proven.
