First report of Nigrospora oryzae (Berk. and Broome) petch causing stem blight on Brassica juncea in India
Journal of Phytopathology 161 (6), 439-441
Abstract: A stem blight disease was observed on the lower portions of Brassica juncea stems during the cropping season (2010-2011). In advanced stages, the lesions were up to 120 cm in length on the stems and also spread to petioles and midribs of leaves. The purified fungus was identified as Nigrospora oryzae (Berk. and Br.) Petch (teleomorph Khuskia oryzae), which produced similar symptoms when healthy B. juncea plants were inoculated, thus proving Koch's postulates. This is the first report of the occurrence of N. oryzae on B. juncea.
