Abstract: The results of application of herbicides and insecticides in crops cultivated in the Volga region, their influence on processes occurring in plants, changes in the chemical composition and length of the vegetation period are considered. Application of herbicides had a positive effect on the chemical composition of the vegetative mass of spring wheat. The nitrogen content was 0.07 mg% higher than in the control, phosphorus content was 0.16 mg% higher. By harvesting in plots where herbicides were used, the content of all nutrients exceeded control. Weather conditions of the vegetation period have a great influence on the nutrient content. The least amount of nitrogen and potassium was in the vegetative mass of crops in favorable years. The most intensive reduction of nitrate nitrogen after the introduction of chemical means of plant protection occurs in dry years. The content of nitrate nitrogen, phosphorus, potassium in millet grain, spring wheat, chickpeas, coriander and oats in variants with the use of chemical plant protection products (herbicides, insecticides) was at or above the control level. It has been established that herbicides and insecticides did not adversely affect plant development conditions in biochemical processes in plants.
