FIELD: agricultural chemistry. SUBSTANCE: mycorhizal fungus growth stimulation composition contains plant material and plant growth stimulator in the form of alkali metal formononetinate. Agricultural composition for stimulating growth of plants in presence of VAM fungi may as well contain dispersing agent, formononetinate content in medium ranging from 0.1 to 400 ppm. Composition can be used to grow vesicular treelike mycorhizal mushrooms for weakening pesticide or herbicide damage of plants by way of growing plant cells or plants in soil in presence of mycorhizal fungi and alkali metal formononetinate. EFFECT: increased colonization of plant roots by mycorhizal fungi and stimulated plant growth. 27 cl, 3 dwg, 4 ex
