FIELD: agriculture. SUBSTANCE: potato plants at the budding phase or before storage tubers are treated with solution of epibrassinolide-694 (22R, 23R, 24R)-22α, 33α, 22,23-tetroxy-b-homo-7-hydroxy-55α-ergostine-6-one) at con- centration 0.0001-0.01 mg/l. Tubers or plants of potato treated with epibrassinolide-694 show decreased sensitivity to the damage effect of fungi as compared with control or treated with hydrel ones. Tuber seedling long at the storage after treatment with brassinolode-694 is shorter than in control or treated with hydrel ones. EFFECT: enhanced resistance of potato at the storage to the diseases and germination. 2 tbl
