METHOD OF PRODUCING BIOLARIX PREPARATION Russian patent published in 2021 - IPC C09F1/00 A01N65/06 A01P21/00 A01P3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to a method for production of biologically active preparation from larch tree basis. Method for preparing the BioLarix preparation involves extraction of larch cleaned from bark and ground larch with 50 % alcoholic solution at ratio of 1:5 at temperature of 35–50 °C, mechanical separation of the extract, its filtration and concentration on a vacuum evaporation apparatus for thickening the resin. Further, concentrate is cooled and resin is hardened at temperature from 35 to 55 °C. Process of producing a water-soluble resin is carried out in a reactor with a mixer, where the ethoxyhydroglycol and the selected resin are loaded at ratio of 1:1 and mixed at temperature of 55 °C until complete dissolution of resin. Mixture is cooled to 20 °C and introducing the solubilizer Tween-80 in ratio of components ethoxydiglycol:lignis:tween-80 - 1:1:0.5.

EFFECT: obtained biologically active product has growth regulating and fungicidal action, which enables its high efficiency as fertilizer.
