In the conditions of the Republic of Belarus there were presented the four-year results of field experiments on the efficacy of herbicides mixtures against annual dicotyledonous weeds in oil flax (Linum usitatissimum). In 2008 into the "State Register ..." for use on flax-fiber flax there were added preparations on the basis of sulfonylurea derivatives: akkurat, WDG (metsulfuron-methyl, 600 g / kg) and the picador, WDG (prosulfuron, 750 g / kg). In this regard, we conducted field experiments to study the effectiveness of these drugs in linseed crops. It is established that the contamination of weed species with a predominance of Chenopodium album to use herbicides mixes: picador, WDG (15 g/he) + 2M-4X 750, w.s. (0,5 l/he); akkurat, WDG (6 g/he) + 2M-4X 750, w.s. (0,5 l/he) - the biological efficacy against dicotyledonous weed species reaches 94,1%. The herbicides mixes of the picador, WDG (15 g/he) or akkurat, WDG (6 g/he) exactly with 2M-4X 750, w.s. (0,5 l/he) on the efficiency do not concede to mixes of herbicides the secator turbo, OD (50 ml/he) or charmoni DFS (10 g/he) with 2M-4X 750, w.s. (0,5 l/he).
