FIELD: biotechnology.
SUBSTANCE: invention is method for reducing the incidence of rhizoctonia disease and improving the quality of the potato harvest, comprising a single pre-planting treatment of potato seed tubers with a polyfunctional biopreparation in liquid form by spraying, wherein during pre-planting treatment of seed potato tubers, an aqueous suspension of blastospores of entomopathogenic fungus Metarhizium robertsii (strain MB-1, number VKM F5018D) with titre 5×107 CFU/ml in amount of 12 l per 1 ton of seed potato tubers is used as a liquid form of a polyfunctional biopreparation.
EFFECT: invention widens the range of methods of reducing rhizoctonia disease incidence and improving the quality of potato harvest.
