COMPLEX PREPARATION FOR PRE-SOWING TREATMENT OF SPRING WHEAT SEEDS BASED ON GIBBERELLINS AND POLYSORBATE 20 Russian patent published in 2020 - IPC A01N25/02 A01N37/08 A01P21/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to development of plant growth stimulants for presowing treatment of spring wheat seeds. Technical result is achieved by the fact that complex preparation for pre-sowing treatment of spring wheat seeds by semi-dry method includes potassium or sodium humate, brewer's yeast autolysate, calcium bentonite, gibberellic acid salts and Polysorbate-20 and represents a bentonite-humate complex in the form of an aqueous suspension containing said components in the following concentration: gibberellins (gibberellic acid salts) 35–45 mg/l; potassium or sodium humate 8–12 g/l; calcium bentonite 35–45 g/l; brewer's yeast autolysate 10–14 g/l; Polysorbate-20 is 100–150 mg/l.
