METHOD OF PRODUCING GEL-LIKE GROWTH STIMULATOR FOR ROOTING CONIFEROUS PLANTS Russian patent published in 2024 - IPC A01N25/04 A01N43/38 A01N65/00 A01N59/14 A01N31/00 A01P21/00 

FIELD: agriculture.

SUBSTANCE: method of producing a gel-like growth stimulator for rooting of coniferous plants involves grinding plant material, mixing the material with water, extraction, separating the extract by filtration, mixing the extract with a gelling agent, indolyl-3-butyric acid in form of a potassium salt, a food coloring agent, boric acid and distilled water. Young sprouts of goat willow are used as vegetal raw material, extraction of which is carried out with water at a water ratio of 1:15 for 16–18 hours at temperature of 75±5 °C. Gelling agent used is hydroxyethyl cellulose. Initial components are used at following ratio, wt.%: young sprouts of goat willow—45–47, hydroxyethyl cellulose—1.4–1.6, indolyl-3-butyric acid (potassium salt)—0.2–0.3, food coloring agent E101—0.01, boric acid—2.29, distilled water—48.8–51.1.

EFFECT: proposed method of producing a gel-like growth stimulator for rooting coniferous plants is easy to implement, provides for the production of biologically active substances and auxins from plant material, organic solvents are not used in the method, which increases environmental friendliness of the process.
