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, Curvulariasp/ 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.
