In course of the research there was studied the efficiency of insecticide application in the protection of oat (Avena sativa) crops from pests of sprouts. The research was realized in the conditions of the Republic of Belarus in 2007-2009 on sod-podzolic light loamy soil, developed on medium-textured loam, underlie from depth of 0.9 m of moraine loam. The agrochemical indicators of arable horizon were: humus content - 2.0-2.2%, pH (in KCl) - 6.0-6.3, P2O5 - 170-180 mg/kg, K2O - 190-200 mg/kg of soil. As a result of realized research it was revealed that the application of the insecticides Fastak, 10% ex. (0.1 l/ha), Danadim, 400 g/l e.c. (1.2 l/ha) and Komandor, w.s.c. (0.1 l/ha) as well as seed treatment by Komandor, w.s.c. (1.5 l/t) made it possible to keep 1.9-2.5 c/ha of grain and to obtain 1.4-5.7 dollars/ha of conditionally pure income at the profitability of the application of preparations equaled to 5.5-32.5%. Post emergence use of the insecticides of Fastak, 10% e.c. and Komandor, w.s.c. was the most profitable (32.5 and 28.8%, respectively).
