Virulence frequency of Blumeria graminis f. sp. Hordei and the occurrence of powdery mildew on four winter barley cultivars

Powdery mildew caused by Blumeria graminis f. sp. hordei is one of the most important diseases of barley in Poland. B. graminis is a genetically diverse pathogen with different special forms and races. The aim of the two-years’ experiment was to assess of B. gramins f. sp. hordei virulence frequency and powdery mildew occurrence on four winter barley cultivars. Virulence frequency of the pathogen depended on place and term of exposition. The occurrence of powdery mildew on four winter barley cultivars depended on virulence frequency of the pathogen and weather conditions.
