METHOD OF PROTECTING VEGETABLE CROPS FROM VIRAL INFECTIONS Russian patent published in 2024 - IPC A01N25/02 A01N59/00 C01B15/01 A01P1/00 

FIELD: agriculture.

SUBSTANCE: method of protecting vegetable crops from viral infections when growing in a greenhouse includes, after harvesting plant residues of the previous harvest, treating the structures of supports for plants with a solution with a hydrogen peroxide concentration of 45-55% and with a stabilizing element (HPaS), which is silver with concentration of 3.5-4.5%, disinfection of inner volume of watering hoses with solution of nitric acid with concentration of 1.5-2.5% for 22-26 hours, covering the floor film or cleaning the agricultural fabric, repeated treatment of the structures of supports for plants with a solution of HPaS with concentration of 3.5-4.5%, disinfection of drip irrigation tips with a solution of nitric acid with concentration of 0.85-1.15% for 22-26 hours. Further, mats for growing plants are laid into the greenhouse, drip irrigation tips are inserted, structures of supports for plants are treated with a solution of HPaS with concentration of 3.5-4.5%. At the stages of growth of vegetable crops, water is prepared by mixing it with a solution of HPaS with concentration of 55-65 ppm, mats are saturated with it and the planted plants are watered. After three days from planting, the concentration of the HPaS solution is 75-85 ppm. After seven days from planting, the concentration of the HPaS solution is 95-105 ppm. When plants reach height of 0.95-1.05 m, external parts of plants are treated with HPaS solution with concentration of 0.3-0.4% and treatment is continued every five days. Tomatoes and cucumbers are used as vegetable crops.

EFFECT: proposed method of protecting vegetable crops from viral infections provides complex protection of plants and medium for growing plants and increases efficiency of fighting viral infections.
