FIELD: biological agriculture. SUBSTANCE: invention can be used in biotechnology, plant growing, fruit and vegetable growing for preparing ecologically pure agriculture production. Invention proposes multifunctional activating agent of fruit formation based on natural phytohormones and containing trace elements and macroelements. Activating agent comprises two phytohormones simultaneously: cytokinins produced by consortium of lactic acid microorganisms (VKPM = 5973) including Lactobacillus lactis, Lactobacillus salivarius, var. salivarius, Lactobacillus acidophilus and gibberellins as gibberellic acids salts, carbamide, macroelements as potassium salts of phosphoric and sulfuric acids, trace elements Zn, B, Mn, Mg, Fe, Cu and stabilizing agents, natural biopolymers, surface-active substance, dry skimmed milk or whey, potassium citrate. Multifunctional bioactivating agent of fruit formation contains dry skimmed milk or whey in the amount 20-30%; macroelements as potassium salts of phosphoric and sulfuric acids taken in the ratio K2HPO4 : KH2PO4 : K2SO4 =3:3:1, respectively, in the amount 0.9-45; 0.9-45; 0.5-13%; trace elements Zn, B, Mn, Mg, Fe, Cu in the amount 0.16-2% totally as salts or chelates; carbamide in the amount 4.8-55%; natural biopolymers in the amount 0.1-0.5%; potassium citrate in the amount 0.1-1.5%; stabilizing agents in the amount 0.1-0.3%; surface-active substance in the amount 1-2%. Invention promotes to increase number of female flowers, improved pollination of flowers and setting fruits, enhanced intensity of photosynthesis, adsorption-absorption capacity of plants roots, yield and its quality, plants protection against diseases, prolonged period for yield gathering. EFFECT: enhanced and valuable properties of bioactivating agent. 3 cl, 7 tbl
