Efficiency of Using Herbicides in the Weed Control in Vineyards

Abstract

The article examines the impact of the use of herbicides alternately with agrotechnical measures on the economic indicators of the grape harvest in integrated weed control, designed to keep their spread below the level of economic damage. The effects of herbicides used to control weeds were analyzed by variant. The species composition of weeds in the vineyards was determined, the correct selection of herbicides and chemical control were carried out alternately with agrotechnical measures, strictly observing the rules for the use of herbicides. Timely chemical control led to a reduction in harmful weeds until the end of the season. As a result of reduced environmental risk, the economic performance of grape production also increased significantly with increasing yields. Compared to the control, the yield in all variants was 12.38-18.27%, the profitability was higher in the range of 8.21-28.6%. Thus, it has been established that the use of herbicides in grape crops infected with annual and perennial weeds is cost-effective and allows for additional income.
