The article summarizes the agro-technical method of pest control, envisaging an annual rotation – «1 year of rice-growing followed by 1 year of soybean-growing» instead of the former approach – «3 years of rice growing with 1 year of soybean-sowing». As a result of the experimental approach «1 year of rice – 1 year of soybean growing», the number of pests decreased by 42.8% or 20 units. The yield of rice (of the Mustakillik and Iskandar varieties) sown according to this scheme achieved 60.3 – 58.5 centners, which is 4.4 – 4.6 centners more than in the control period. Tsiperfos (1.0 l / ha) and Karate (0.5 l / ha) drugs were used against the pest of the crustacean shchitnya in the cultivation of the Mustakillik variety, which increased the yield (73.4-73.8 centners/ha in total) by 20.7-21.1 centners per hectare relative to the control period. Due to the use of this insecticide in the cultivation of the «Iskandar» variety, the crop reached 68.8-70.7 centners per hectare, the yield increased by 15.5-18.0 centners per hectare compared to the control period.
