Abstract
Occurrence of powdery mildew was found on Japanese plum (Prunus salicina) growing in private gardens in Yanggu, Hongcheon, Hoengseong, and Gapyeong of central Korea, in 2011. Despite of extensive survey, however, there was no powdery mildew infection in commercial orchards of Japanese plum in Korea. The initial symptoms included white, evanescent mycelia and irregular patches on leaves and young stems. Infected leaves later showed partial distortion and diffuse red-purple discoloration. Based on morphological characteristics of holomorph and phylogenetic analysis, the causal fungus was identified as Podosphaera tridactyla. This is the first report of powdery mildew on Japanese plum in Korea.
