The article identified 10 species of pests that damage rice plants during the season in rice agrobiocenosis. Leptestheria dahalacensis Sars, Apus concriformis Sh., Ostrinia nubilalis Hb, and Cephus pygmaeus have been reported to cause damage to rice grasses. A growth calendar has been developed. In the pest experiment during the rice germination period, Nurell D was found to contain 55% em.k. (Cypermethrin + chlorpriphos) - in the variant applied to 1.5 l/ha, the biological effectiveness of the drug is the highest for 14 days - 93.9%, in the variant treated with Tayshin 500 s.d.g (Clothianidin) -0.06 kg/ha for 14 days - 93.3%. In the experiment, the main pest Nurell D in the variant using 55% (1.5 l/ha) was 73.8 quintals of Iskandar variety, ie 13.2 quintals per hectare compared to the control, the new chemical Taishin 500 s.d.g. (0.06kg/ha) yielded 70.7 q/ha in the variant in which the chemical agent was used, and 10.1 additional yields were reported.
