COMPLEX PREPARATION FOR PRE-SOWING TREATMENT OF SPRING WHEAT SEEDS BASED ON POLYETHYLENE GLYCOL AND PHYTOHORMONES Russian patent published in 2021 - IPC A01N25/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, and in particular to the development of preparations-stimulants of plant growth for pre-sowing treatment of seeds of spring wheat. The technical result is achieved by the fact that a complex preparation for pre-sowing treatment of spring wheat seeds by a semi-dry method includes potassium or sodium humate, autolysate of brewer's yeast, calcium bentonite, gibberellic acid salts, polyethylene glycol, 6-benzylaminopurine and 3-indoleacetic acid (heteroauxin) and is a bentonite-humate complex with phytohormones in the form of an aqueous suspension containing the indicated components in the following concentration: 3-indoleacetic acid (heteroauxin) - 20-25 mg / l, gibberellins (gibberellic acid salts) - 250-350 mg / l, 6-benzylaminopurine - 6-12 mg / l, humate - 8-12 g / l, calcium bentonite - 35-45 g / l, autolysate of brewer's yeast - 10-14 g / l, polyethylene glycol - 250-350 mg / l.

EFFECT: technical result achieved with the use of the present invention consists in increasing the stimulating ability of preparations for pre-sowing seed treatment in a semi-dry way, which is reflected in the acceleration of the germination of spring wheat seeds and the development of their seedlings.
