Abstract

During the winter season of 2011, Cochliobolus lunatus was isolated from necrotized leaves of potato in potato plantations of Burdwan District, West Bengal State, India. The isolate was identified using standard monographs and taxonomic keys and confirmed molecularly using the Ribosomal Deoxyribonucleic acid (rDNA) sequence data. The Koch’s postulate was confirmed through pathogenicity test on potato cultivar ‘Kufri Jyoti’. This is the first report of C. lunatus causing brown-to-black spots disease of potato in India.
