FIELD: agriculture, plant protection. SUBSTANCE: vegetating plants of sugar beet should be treated with aqueous GibberROS solution at 50-100 mg/l concentration at the dosage of 15-30 g/ha. Plant treatment should be carried out 3 or 4 times beginning since the phase of 8-10 leaves appearance. Application of the present method should enable to decrease plants' affectability with Cercospora leaf spot by 3.4-4.5 times; peronosporosis, by 2.7-3.6 times; erysiphosis, by 2.1-2.5 times; rust, by 2.0-2.4; and regional spot, by 1.6-2.6 times.
