Abstract Ridge gourd (Luffa acutangula) is an herbaceous perennial twining vine cultivated globally as vegetable and medicinal plant. During October to January in 2014 and 2015, 40% powdery mildew disease incidence was observed in different areas of Odisha state, India. The pathogenicity experiments confirmed the powdery mildew disease symptoms on artificially inoculated L. acutangula seedlings. Causal organism was identified as Podosphaera xanthii on the basis of morphological and molecular studies. This is the first report of powdery mildew disease on L. acutangula caused by P. xanthii.
