Abstract The influence of different norms of herbicide Kalibr 75 and its mixtures with Agat-25К and Agrostymulin on the physiological processes course in the plants of spring barley is investigated. It is determined that under the herbicide Kalibr 75 (40–60 g/ha) with biological preparations, the activity of antioxidant enzymes in the plants of spring barley considerably increases and flowing of physiological-biochemical processes amplifies. On the whole it contributes to activation of exchange processes passing in the plants, directed on detoxication of products of metabolism induced by the influence of xenobiotic. The highest top biomass, area of leaf apparatus and the biggest content of chlorophyll, in the leaves of spring barley are formed in sowings under the action of herbicide Kalibr 75 in the norm 40 g/ha in tank mixture with biopreparation Agat-25K and plant growth regulator Agrostymulin, under which the highest increases in yield are provided.
