Abstract

First report of Bipolaris australiensis causing pod rot of senna in India.

Abstract

Surveys conducted in Rajasthan and Uttar Pradesh, India, in May 2010, revealed the presence of brown, circular to irregular, minute to large necrotic spots on senna (Senna angustifolia) pods which later turned into pod rot. Similar symptoms were also observed on leaves and stems. Seeds in infected pods were malformed and had reduced viability. Morphological and pathogenicity tests identified the fungus as Cochliobolus australiensis. This is thought to be the first report of C. australiensis infecting S. angustifolia in India.
