First report of Erysiphe bunkiniana from Pakistan

Abstract

During August–September 2018, powdery mildew symptoms were observed on both surfaces of leaves of Isodon rugosus in the Abbottabad and Malakand districts of Pakistan. The causal agent was identified as Erysiphe bunkiniana, based on its asexual morph and chasmothecia, and its identity was confirmed by molecular data. This is the first Pakistani report of Erysiphe bunkiniana and the first sequence obtained for this powdery mildew species.
