Abstract The results of three-year research of effects of different norms of herbicide Lontrim together with Emistym C on the enzyme activity of redox nature, the content of chlorophyll in leaves of winter wheat variety Bilosnizhka and the yield in the conditions of Right-Bank Forest-Steppe are given to determine the most effective, biologically-based, ecologically safe measures of controlling weeds in the crops. The results showed that the enzyme activity of redox nature was different. The most active catalase, polyphenol oxidase, peroxidase were during introduction of Lontrim at norm 1.5 l/ha with Emistym C and their indicators were higher than the control by 32.7, 24.6 and 7.7%, respectively, which contributes to increase of vital activity of plants. The best conditions for increasing the amount of chlorophyll and its high indicators were observed during the application of Lontrim at norm 1.5 l/ha with Emistym C and were respectively higher than control by 50%. Winter wheat yield depended on the norm of applicated product. Introduction of the herbicide in winter wheat sowings in the optimal norm (1.5 l/ha) and growth regulator positively affected on increase of yield. At this norm the highest crop productivity was observed, compared with the control, which increased by 18%.
