The development of technologies for the environmentally friendly biopreparations production and use including biopreparations based on acrylic hydrogel and protein growth stimulant, which is obtained by chemical hydrolysis from by-products of slaughtered animals processing is carried out as part of the optimization of the phytosanitary condition of wheat crops and creation of favourable agro-ecological conditions for its cultivation. An important feature of acrylic hydrogel is the ability to retain and release water to plants when needed. At the same time, protein hydrolysate can provide plants with an additional source of nitrogen which is a component of plant proteins, chlorophyll and it is necessary for normal growth and development of plants during the vegetation. The addition of the protein growth stimulant to acrylic hydrogel expands the potential application of Super Moisture Absorbent (SMA) due to the long-term growthstimulating effect on plants. The acrylic hydrogel and protein growth stimulant were added to the soil when wheat sowing in the certain concentrations and proportions. Wheat productivity was studied by the indicators complex, characterized the plants morphological features and the yield structure. Assessment of the degree of plant affection caused by pathogens was carried out both according to the generally accepted phytopathological indicator - conditional intensity of development, and using additional parameters. In the research, it was found that acrylic hydrogel and protein growth stimulant provide an increase in wheat yield and reduce the pathogens harmfulness. In combined application, they can be used in agriculture for wheat cultivation as a low-cost and environmentally friendly soil conditioner.
