Abstract

Pesticide treatment of grain crops with pesticides - fungicides, herbicides, and seed dressers - plays a key role in ensuring high harvest quality. The objective of the study was to evaluate the effectiveness of integrated plant protection applications to ensure the phytosanitary stability of spring wheat crops in the Ryazan region. The experiments were conducted in 2024-2025. The spring wheat protection scheme included: seed treatment with Sterling, WSC at 1.5 L/t and Graviet, SC at 1.5 L/t; treatment in the tillering stage with a tank mixture containing the systemic fungicide Rakurs, SC - 0.2 L/ha, the insecticide Borey Neo, SC (125+100+50 g/L) - 1.0 L/ha and the herbicides NordStream, WDG - 0.07 L/ha, Stingray, EC - 0.35 L/ha; treatment at the flag leaf stage with the fungicide Lantsea, CME at 0.8 L/ha. The research showed that the development of root rot in spring wheat crops did not exceed 2-3.5%, and the prevalence of the disease was 4-14.1%. The use of the fungicide Rakurs, SC reduced brown rust development by 12.3-13.4% and decreased its prevalence by 35-45.6%. The biological efficacy of the agent reached 48.3-58%. The use of the herbicides NordStream, WDG and Stingray, EC reduced weed infestation of the crops, providing a high level of efficacy against annual and perennial dicotyledonous weeds (95-97.4%) and grass weed species (97.5-97.6%). The results confirm the feasibility of the integrated use of plant protection products to maintain phytosanitary stability and increase the yield of spring wheat.
