Abstract: Gray mould of capsicum (Capsicum annuum var. grossum) caused by Botrytis cinerea Pers. is one of the most destructive diseases of winter season capsicum under polyhouse conditions in Himachal Pradesh. During 2013-14, different polyhouses of Bilaspur, Hamirpur, Kangra and Kullu districts of Himachal Pradesh were surveyed and disease severity was observed between 18.0-52.0 per cent in all the polyhouses. Maximum disease (52.0%) was recorded at Palampur in Kangra district whereas, minimum (18.0%) at Ghumarwin in Bilaspur. Studies on symptomological, morphological and cultural characteristics identified the associated pathogen as Botrytis cinerea. The identity of pathogen was also confirmed through rDNA analysis by targeting ITS1 and region using primer pair ITS1 and 4 which generated an amplicon of ~500bp and phylogentic analysis showed 99 per cent homology of the isolate with Botrytis cinerea.
