Varietal reaction of winter wheat to the use of pesticides

Abstract

In production experiments carried out in the crops of winter wheat of two varieties Iziuminka and Stanichnaya at the FSUE Kalininskoye enterprise in the Volgograd region, it was found that a decrease in weediness of crops and the number of pests as a result of the use of pesticides contributed to an increase in the yield of the variety Izuminka by 7 centners / ha, variety Stanichnaya on 4 c / ha. The use of pesticides also affected the gluten content in grains, its amount increased from 33% to 36% in the Stanichnaya variety and from 30% to 34.5% in the Iziuminka variety. A varietal reaction to the use of pesticides was revealed. Variety Izuminka showed greater sensitivity to the improvement of the phytosanitary situation as a result of the use of pesticides than variety Stanichnaya.
