Effect of plant growth regulators on possibility of reduction of insecticide load in agrocenoses of winter wheat

Abstract

Insecticides BI-58 new and Diazinone decrease the extent of damage of the winter wheat culm by cereals flies 7,2–8,0 times in comparison with the control. Combination of the studied insecticides with the mixtures of growth regulators allows to decrease the rate of insecticides application by 20 % without any increase of the culms damage by the pests.
