FIELD: agriculture, plant growing. SUBSTANCE: it is suggested the preparation for treating plants and method for its obtaining including successive extraction of Mortierella globalpina micromycete with nonpolar extragent in supercritical state with water, alkali, water, acid, water, alkali and water followed by combining solid residue with the first extract, and, also, method for treating plants at manufacturing plant growing production with said preparation. The innovation enables to enhance action spectrum of obtained preparation to treat plants and raw material basis, increase coefficient of raw material usage in manufacturing preparation to treat plants. EFFECT: higher efficiency of production. 8 cl, 2 ex
