Based on the statistical data of the Federal Service for Hydrometeorology and Environmental Monitoring, the Federal State Statistics Service, and the Unified Interdepartmental Statistical Information System, this paper analyzes the dynamics of pesticide use in the Altai Region’s cereal cropping from 2010 through 2019. It was found that the amount of plant protection products used in the Region increased and that increased the pesticide load on the soil. In 2010, the cereal crop growers purchased herbicides based on 45 active ingredients, and in 2019 - based on 58 ones. The amount of purchased products based on the above active ingredients ranged from 149 to 286 tons that accounted for 67-75% of the total volume of herbicide products. Throughout this period, 31-71 g per hectare of the basic herbicides per unit of sown area were applied in the Region; generally, this led to increased cereal crop yields; the grain yields ranged from 0.9 to 1.6 tons per hectare. However, the increasing rates of pesticide application were much higher than the rates of yield increase. In the neighboring regions of the Siberian Federal District, the application volumes of the same pesticides were higher than in the Altai Region.
