The influence of potato inoculation with microbial preparations Hetomik and Biogran was studied. It was shown that Hetomic possess stable fungicide action that is more evident in organic-mineral fertilization systems: affection with bare patch, blackleg, ring rot and late blight was decreased on 38–67 %. Application of Biogran promotes optimization of potato mineral nutrition because of biological transformation of microelements compounds, thus enhancing yield increase and improving product quality. Biogran efficiency was more considerable in variants without mineral fertilization and under the use of alternative fertilization systems.
