Abstract
Powdery mildews are a widespread group of plant pathogens, capable of causing serious yield losses. This study aims to outline species composition of powdery mildew fungi infecting fruit crops in Sverdlovsk region of Russia. Original collections and IPAE UB RAS herbarium specimens were studied and literature analysis was conducted. The results reveal 21 species of powdery mildews infecting 29 species of host plants from 11 families in Sverdlovsk Region. Most of the fungi are alien to the region. The majority of fungal species belong to Podosphaera genus. Shares of abundant, rare and single-time collected powdery mildews are equal. Abundant species belong to Podosphaera and Erysiphe genera. Raspberry-infecting fungus Podosphaera ruborum (Rabenh.) M. Bradshaw, U. Braun et M. Liu is recorded in the region for the first time. The majority of host plant species belong to Rosaceae. More species of powdery mildews might be soon found on fruit crops in Sverdlovsk region due to climate change, introduction of new cultures and arrival of new pathogenic fungi.
