Abstract

<p>The article summarizes agro-technical method of pest control, envisaging an annual rotation&ndash; &laquo;1 year of rice-growing followed by 1 year of soybean-growing&raquo; instead of the former approach &ndash; &laquo;3 years of rice growing with 1 year of soybean-sowing&raquo;. As a result of the experimental approach &laquo;1 year of rice &ndash; 1 year of soybean growing&raquo;, the number of pests decreased by 42.8% or 20 units. The yield of rice (of the Mustakillik and Is kandar varieties) sown according to this scheme achieved 60.3 &ndash; 58.5 centners, which is 4.4 &ndash; 4.6 centners more than&nbsp;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 &laquo;Iskandar&raquo; 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.</p>
