It was discussed the results of studies on the development of formulations and original preparative forms of protectants based on benzimidazole substances (Carbendazim, Benomyl) using alternative form-building components. By the testing of protectants based on the fungicide Benomyl was shown that these preparations completely healed the inoculum from fungi Bipolaris sorokiniana, Fusarium spp. During the entire vegetation period, new protectans successfully controlled root rot with a decrease in the development index in the phase of 2 leaves - in 2.1-2.7, in tillering - 1.2-1.4 and in milk ripeness - 1.4-1.5 times . These products studied influenced the growth processes and the density of crops, their positive impact was noted for almost all indicators of the structure of the productivity of soft spring wheat, which ultimately affected the yield of grain. The obtained results testify to the prospects of continuation of studies on optimization of preparative forms of protectants using mechanochemistry methods. Methods of mechanochemistry were used to obtain innovative compositions of fungicide-etchants based on Carbendazim and water-soluble polymers for complex protection of potatoes from pathogens during storage and black scab. It has been established that the introduction of arabinogalactan and hydroxyethyl starch polysaccharides into these preparations made it possible to significantly increase the water solubility of Carbendazim and to obtain potato tuber pickles with improved physico-chemical, technological and biological parameters. Testing protectants in the field showed synergy of biological properties, manifested in accelerating the growth of plants and their mass, reducing the development of black scab on stems and increasing the productivity of the crop. It was shown that the Carbendazim compositions with these polymers possessed high biological activity at a reduced consumption of the preparation.
