In the Chuvash Republic, peas are cultivated as a food and feed crop. Great damage to crops caused by weeds. With severe contamination, the reduction in grain yield in farms is 35-50 %. In order to obtain high yields of pea grain, experiments were conducted with the use of herbicides. The article discusses the research conducted in 2018-2020 on the effectiveness of a two-component herbicide Korsar Super normal 1.2 l/ha in phase 4-5 leaves of a cropper and the early phases of development of weeds in crops of pea varieties Spartak in the southern part of the Volga-Vyatka region of Russia. During the fieldwork experience in the Chuvash Research Agricultural Institute – Branch of “Federal Agricultural Research Centre of the North-East named N.V. Rudnitsky” on loamy gray forest soil, the use of herbicide treatment led to a significant reduction in the number of weeds in biological effectiveness 84.2 %. It provided a reliable grain increase of 0.9 t/ha. At the same time, the level of profitability of grain production made averaged 33 % in 2018-2020.
