In the conditions of the Republic of Belarus there were developed new formulas for dressing of fiber flax (Linum usitatissimum) seeds basing on plant protection preparations, trace elements, biological plant stimulants and Gisinar which made it possible to provide qualitative seed treatment, plant resistance to diseases and unfavorable environment factors, increasing of yielding capacity of sowings and quality of flax products. Seed dressing was realized by protective and promoting mixtures: Vitavax 200 FF (34%, aquatic suspension concentrates, in dose 2.0 l/t seeds); Vintsit (5%, suspension concentrates, in dose 1.5 l/t seeds); Gisinar (aquatic suspension, in dose 100 g/t); Boron (boracic acid, 0.5 kg/t); Zinc (zink sulfate, 0.7 kg/t); Gidrogumat (10%, aqueuos solution, in dose 200 ml/t). In course of the study there were analyzed seeds and sowings of fiber flax of the following varieties: early ripening Praleska; mid ripening E-68; and late ripening Pramen). Mineral fertilizers were applied to all variants in doze of N30P60K90 (ammonium saltpeter, ammonium superphosphate and potassium chloride). Barley was the preceding crop. Research results showed that application of composition of Gisinar, Vintsit, Zn, Boron and Gidrogumat increased germinative ability of seeds on 95% for Praleska variety and on 87% - for E-68 variety. Application of Gisinar, Vintsit, and Zn composition increased germinative ability of seeds of Pramen variety on 90%. Seeds dressing of Praleska and E-68 varieties with a composition Gisinar, Vintsit, Zn, Boron and Gidrogumat made it possible to obtain the maximal yield of flax straw - 73,2 and 69,9 c/ha. The same composition with seed disinfectant Vitavax 200 FF provided yield of Pramen variety of 70.9 c/ha.
