Grape leave samples with powdery mildew symptoms in vineyard of Spassk Dalny, Primorsky Territory

The south of the Russian Far East is a promising region for grape growing. However, due to the humid climate with moderate temperatures, grapes grown in this region are highly susceptible to diseases such as powdery mildew. Classical approaches to the treatment of this disease are often ineffective. In this work, the pathogens of Far Eastern grape varieties with external symptoms of powdery mildew were identified.
