The influence of mineral, organic and mineral fertilizers and biological products on increasing the resistance of potato plants to widespread diseases - late blight, alternariosis and rhizoctoniosis is considered. The positive effect of organic fertilizer Reasil and biological product Flavobacterin on the phytosanitary state of plants in crops and potato productivity is shown. The protective activity of these fertilizers against late blight and potato alternariosis was revealed, which made it possible to reduce the development and prevalence of diseases during the potato growing season compared to untreated options. The growth-promoting effect of Reasil and Flavobacterin on a crop was established; a significant effect in increasing the productivity of potato agrocenoses was noted.
