Banana is (Musa sp) one of the most exoteric and materialistic fruit crop of many tropical and subtropical areas in India. Banana leaf diseases, caused by several fungal pathogens are one of the major diseases. Among the fungi causing banana leaf diseases, Curvularia sp/C. lunata is one of the main causal organisms causing leaf spot disease in banana plant. Two fungal isolates- MUSLF-2, MUSLF-3 and one fungal isolate- MUSLF-1 were isolated from the infected leaf from Ramganj and Gotgaon locations. Based on light microscopic and scanning electron microscopic studies, MUSLF-2 and MUSLF-3 were identified as Curvularia sp. After Koch’s postulate, three fungal isolates- MUSLF-2, MUSLF-3 [Curvularia sp] and MUSLF-1 were applied in banana field along with foliar spray of spore suspensions. The symptoms were similar to those observed in the in vitro detached leaf inoculation technique. The present research work depicts about the severity of leaf spot diseases of Musa paradisiaca and the nature of mode of infections exhibited by the fungal pathogens.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
