Abstract. The study aimed to determine the possibility of using biological products to regulate the number of dominant soybean pests (Tetranychus Dufour spider mite, Helicoverpa armigera Hbn. cottonworm, Etiella zinckenella Treitschke acacia moth, and Nezara viridula L. adventive stink bug). The work was performed in 2018–2020 on soybean crops in a scientific 10-field grain-row crop rotation. We conducted preliminary laboratory screening of a number of biological products and BAS of biogenic origin (including suspensions of essential oils of coriander, wormwood, dill, and fennel) against spider mites and stink bug N. viridula (adults and nymphs of the third age), according to the results of which biological remedies were selected for field trials. In field experiments, we studied the effectiveness of a suspension of coriander essential oil, biological products Fitoverm-M EC, Biokill EC (2 L/ha), and Biostop P (0.1 kg/ha) against spider mites; the standard was Karate Zeon MES (0.4 L/ha). We tested biological products Biostop P (0.1 kg/ha), Bitoxibacillin WP (2.0 kg/ha), and Lepidocid SC (2.0 L/ha) against lepidoptera; the standard was Karate Zeon MES (0.4 L/ha). We examined suspensions of essential oils of coriander and wormwood and biopreparation Fitoverm-M EC (2 L/ha) against bug N. viridula; the standard was Bi-58 Top EC (0.4 L/ha). The control option in all experiments was the option without treatment. The effectiveness of coriander essential oil suspension and insecticide Fitoverm-M EC against spider mites and N. viridula was 92.9–96.4%. Damage of soybeans by N. viridula decreased, in comparison with the control, by 80.0%. When using the biological product Bitoxibacillin WP against the cotton bollworm and acacia moth, we registered a decrease in the damage to the beans, relative to the control, by 84.3%.
