Abstract

In November 2007, a severe outbreak of powdery mildew disease was observed on a weed species Ageratum houstonianum. Based on the morphological characters the pathogen was identified as a Podosphaera species. This is the first report of this organism causing powdery mildew on A. houstonianum in Meghalaya, India.
