This paper observed that soybean crops were contaminated with a number of specialized and omnivorous pests in the field, during the storage of grain in warehouses and private households. The study identified 18 species of pests belonging to different families. The main pest of the soybean crop is Dalucho 70% (at a consumption rate of 5.0 l/t), Cruiser Extra 362 from insecticide seed pesticides against autumn night worms. (When planted with 3.0 l/t, the biological efficiency reaches 85-90% and protects the soybean during the entire growing season and prevents pest damage. The main pest of soybeans in field studies against cotton bollworm is the poaching parasite in middle and older cotton According to the results of experiments on the application of nightshade worms in different proportions, the efficiency was 29.8% on the 3rd day, 44.5% on the 7th day and 75.0% on the 10th day when the ratio of free-range and host insects was 1:5. When the parasite was applied at a ratio of 1:10, the biological efficiency was 20.7% on day 3, 42.1% on day 7 and 68.0% at 10 days. The last variant in the observations was 20.3% on day 3 when the parasite was used at a ratio of 1:15, 34.4% at 7 days and 56.1% at 10 days.
