An evaluation of the use of sideral precursors and biologics in the cultivation of long-legged flax

Abstract

The paper presents data on the study of the effectiveness of new biological drugs-the biofungicides Trichozan and Vitariz and biological insecticide against the background of the action and aftereffect of the sideral precursors of long-legged flax. The research was conducted in the Scientific Research Center of the Ivanovo State Agricultural Academy in 2018-2020. The positive effect of the action and aftereffect of the sideral precursors on the productivity of plants and the yield of flax was established. The greatest increases in the yield of straw and seeds were obtained in 2019-2020 when flax was placed after the sideral precursors and the complex use of the biological products Trichozan, Vitariz, and Bioinsecticide. The quality of flax straw improved by 0.5-0,25 sortonomer with the interaction of the complex of biological products and the action of siderates and by 0.25 sortonomer-with the use of biological products for the treatment of seeds and plants against the background of the aftereffect of siderates. The level of profitability for the years increased by 41.9-11.7%, respectively.
