Influence of metabolic products of Streptomyces avermectilis on the dynamics of a currant bud mite under conditions of growing plants with a closed root system on the territory of the nursery of ООО Flora-Sad, Kemerovo

The article presents data from the study of the dynamics of the number of currant bud mites in the territory of ООО Flora-sad, Kemerovo for 2018-2020. and the results of the influence of the metabolic products of Streptomyces avermectilis contained in the biological preparation Fitoverm CE on its character are described. Two-year-old black currant seedlings of the Ilya Muromets variety with a closed horse system were used as planting material. The mass release of the phytophage was observed during the formation of the ovary. Metabolic products of Streptomyces avermectilis reduced the yield of currant bud mites during the study period by 1.3-1.5 times. The use of dimethyl sulfoxide as an adjuvant for Fitoverma CE increased the biological effectiveness of this biological product in controlling the number of kidney mites from 71.3% to 74.7%.
