Powdery mildew of watermelon (<i>Citrullus lanatus</i>) caused by <i>Podosphaera xanthii</i> in Japan
Powdery mildew was found on watermelon (Citrullus lanatus) in Okinawa Prefecture, Japan in February and May 2024. The associated fungus was identified as Podosphaera xanthii based on morphological characteristics of the anamorph and molecular analysis of rDNA-ITS regions. No chasmothecium was observed. Podosphaera xanthii is proposed as another powdery mildew pathogen on watermelon in Japan.
