METHOD FOR RESTORING AND INCREASING THE LIFE OF OWN-ROOTED VINE PLANTATIONS AGAINST THE BACKGROUND OF PHYLLOXERA INFECTION Russian patent published in 2023 - IPC A01G17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, increase the resistance of grapeplants to damage by the root form of phylloxera. The method is to use foliar treatments of grapes with physiologically active compounds during the growing season. Foliar treatments are carried out in two terms by spraying the leaf surface of plants with a working fluid flow rate of 0.5 l/bush: treatment period I — 3–8 days before flowering and II period — the beginning of crop ripening with a solution containing 1-phenyl-3-(1.2.4-triazol-4-yl) urea, alpha-naphthylacetic acid and dimethyl phosphate (2- hydroxyethyl) ammonium. For varieties tolerant to phylloxera, treatments are carried out during the first 2 years. Further, the entire period of operation of vine plantations, the specified solution is used in the first processing period, with an interval of three years in a two-year cycle. For varieties susceptible to phylloxera, treatments are carried out during the first 4 years of vegetation. Next, treatments are carried out in a three-year cycle, with an interval of five years, with a solution containing 1-phenyl-3-(1.2.4-triazol-4-yl) urea and dimethyl phosphate (2-hydroxyethyl) ammonium.

EFFECT: restoration and increase in the life of own-root plantations of grapes against the background of infection with phylloxera.
