The quality and quantity of agricultural products depends on the weather conditions in the regions of cultivation. The results of the influence of weather on the degradation rate of pesticides in agricultural products are presented in this paper. Samples were analyzed for the content of pesticide active ingredients by various chromatographic methods. Air temperature has a significant effect on the intensity of metabolic processes in the plant, which determine the degradation rate of pesticides. Air humidity is more important for water-soluble pesticides than for lipophilic ones. Rain, moisture and dew accelerate the dispersal of substances from the aboveground plant parts. When choosing pesticides to protect crops from harmful organisms, it is necessary to take into account the natural and climatic characteristics of the region.
