Economic efficiency of maize crop protection against weeds

The influence of agricultural practices for cultivating corn on the grain yield of this crop was stu- died. It has been shown that in the conditions of the central part of Belarus, with semi-steam tillage after harvesting the previous crop or cultivating stubble oilseed radish and using the herbicides Meister Power, MD (1.5 l/ha), Adengo, KS (0.4 l) in the 3-leaf phase of corn /ha) grain yield, net income and profitability were at the level of using the herbicide Gardo Gold, KS (4.0 l/ha) against the background of post-harvest application of the glyphosate-containing herbicide Volnik Super, BP (2.5 l/ha). At the same time, the herbicide load decreased from 3.38 to 0.09–0.19 kg/ha a. i., i. e., by 94.4–97.3 %, which is of impor- tant environmental significance.
