Not AvailableSclerotinia stem rot caused by Sclerotinia sclerotiorum (Lib.) de Bary was observed for the first time on pigeonpea in Pusa, Bihar (India) during the years 2012–2014. Typical symptoms of the disease included blighting of twigs, stem lesions, and development of cottony white mycelium and numerous large sclerotia on diseased plant parts. The fungus was identified on the basis of cultural and morphological characteristics, and its pathogenicity was also established. The internal transcribed spacer (ITS) region of pathogen was amplified with primers ITS1 and ITS4, which revealed 100% query coverage along with 99% identity with S. sclerotiorum recovered from different hosts. The highest disease incidence was recorded on cultivar ‘ICPL151’, whereas cultivars ‘MAL13’ and ‘Kudrat’ were observed to have significantly less
