Blumeria graminis and Pyrenophora tritici-repentis of wheat are deleterious infections that often require operation monitoring. The probability of mass lesion of crops by phytopathogens is determined primarily by the presence of pathogens' infectious origin, favorable conditions for their development and spread and host plants susceptibility. Protection strategy and tactics should be based on each particular field and conditions of the growing season. Effective protection of wheat from powdery mildew (75 -87%) was provided by fungicides based on 2-3 active substances, especially the drug Falcon (spiroxamine + tebuconazole + triadimenol). The biological fungicide Phytosporin-M (Bacillus subtilis) provided an average biological efficiency of 58% in years with moderate wheat lesion. Operational control of wheat leaves yellow speckle is more advisable to carry out with preparations on the basis of such active substances as “azoxystrobin + epoxyconazole”, “tebuconazole + propiconazole”.
