Abstract

A corm rot disease was observed for the first time in banana. The disease was found to occur in the majority of commercial cultivars grown in different banana-growing states of India. The incidence of the disease was up to 50% and found to occur at an altitude up to 3000 m asl. The pathogen was identified as Sclerotium rolfsii based on morphological characters and rDNA internal transcribed spacer sequence data.
