The technologies of the new protective- stimulating drugs based on whey and herbal extracts, as well as on the basis of fungal melanin and pyrazolines. Technological scheme of obtaining protective stimulant whey extract and licorice root, includes 7 blocks: acceptance of raw materials, quality assurance, separation of fat and casein dust, obtaining plant extracts, fermentation plant extracts whey; sterilization, filling and packaging, storage and marketing. Technological scheme of obtaining protective stimulant of melanin and pyrazoline includes 14 units: 1–3 microbiological preparation for subsequent isolation of mycelial melanin; 4–8 – getting melanin by sonication mycelial alkaline extraction followed by precipitation with hydrochloric acid and pigment dissolving in alkaline medium, 9–10 – preparation of the second component of the drug by chemical synthesis, comprising the reaction of p-sulfoaniline diazotization, azo coupling reaction and the formation of a pyrazole derivative, a compound prepared by further dilution with water, 11 – mixing the components in the optimal ratio; 12–14 sterilization bottling and packaging, storage and marketing. Investigations of quantitative and qualitative indicators of drugs with the aim of standardizing drugs studied their photometric values .The laboratory studies of the effect of protective - stimulating drugs on growth promoting activity of wheat seeds varieties DON- 95. Conducted field research on the application of complex products in the technology of cultivation of winter wheat varieties DON-95, on experimental plots teaching experimental farm SSAU. Develop practical recommendations.
