Abstract
Powdery mildew was observed on Prunus nepalensis during July, 2009. This plant is grown as a fruit crop in the north-eastern hilly region of India. Light and scanning electron microscopy revealed the presence of the anamorph of Podosphaera. Conidial germination patterns indicated it belonged to the P. tridactyla complex of species. This is the first report of powdery mildew on P. nepalensis in India.
