Research results of studies on the improvement of fiber flax (Linum usitatissimum elongata) protection against weeds in the concrete agricultural and climatic conditions of the North-Eastern part of Belarus by means of the comparative analysis of biological and economic efficiency of herbicides and herbicide tank mixtures (Harmony, 75% of dry fluid suspension, 2М-4Х, 750 g/l of water solution, Pantera 4% concentrate of emulsion) were presented. Influence of studied herbicides on yield qualitative characteristics as well as calculation and assessment of economic efficiency of their application were analyzed. Tank mixture Harmony + 2M-4X (0,5 l/ha + 10 g/ha) as well as Harmony (15 g/ha) applied on the basis of Pantera gramicide in doze of 1,25 l/ha provided the maximum (100%) biological effect against dicotyledons and cereals weeds. Gramicide exclusion from the two-stage plant protection lowered flax productivity. Pantera inclusion into tank mixture with anti-dicotyledons herbicies made it possible to obtain flax yield with the lowered on 3% content of bast fiber. Application of Pantera in doze of 1,25 l/ha without the concurrent culture protection against dicotyledons in the given phytosanitary conditions (7 plants/m2 of couch-grass and 21 plants/m2 of barnyard grass) provided the significant increase of flax stock but the amount of obtained yield increase was incommensurable with the extra costs and proved to be economically unprofitable
