In this study we found that treatment of flax seeds with the Avibif S drug the consumption of TMTD Etchant was reduced by 50 % without decreasing the general phytosanitary effect. Moreover, this effect against the bacterial diseases increased. The combination of the Avibif P drug with herbicides (Kharmony + Kortez + Targa Super) accelerated the plant growth, increased their survival by 1.6–3.8 % before harvesting. Application of the Avibif (S and P) contributed to the formation of large (to 6.6–10.6 %) technical stem length and the best quality of flax. Treatment of seeds with Avibif S both in pure form and in combination with TMTD leaded to the significant increase of the flax straw yield by 36.0–36.6 % and the flax seeds by 39.6–40.7 % in comparison to the standard version. Adding Avibif P to the herbicide mixture increased the flax straw yield by 13.5–39.1 %, and flax seeds by 12.9–38.9 %. The cost of the extra flax yield obtained using Avibif (S and P) exceeded the cost of its implementation by more than 11 times, which proved its effectiveness as a new element of the flax cultivation technology.
