Abstract: As a result of the research, the formation of a different phytosanitary situation on pea (Pisum sativum L.) crops was revealed with various tillage methods using. The infestation of pea crops varied significantly depending on the growing season conditions. The introduction of disking and direct sowing increased the infestation of crops with annual and biennial weeds. Population density of yellow thistle and field horsetail increased. Favorable weather conditions can lead to a high spread of rust and gray mold on pea plants. The intensity of pathogen severity increased as the crop matured, regardless of the soil tillage. This indicator was the lowest with the use of disking. The density of the phytophage population also changed significantly depending on weather conditions. Moldboard tillage significantly reduced the population density of pea aphids and gamma armyworms compared to shallow tillage. Direct sowing also contributed to a decrease in the number of phytophages in pea crops. The data obtained should be in demand in the development of an integrated system for the protection of peas from a complex of harmful organisms in the Non-Chernozem Zone of the Russian Federation.
