The post-harvest problem in ripe banana Musa Spp. is a great problem in banana mostly during transport and storage. Among different problem the rotting of ripe banana after harvest due to Colletotrichum spp. is very important. To get some solution about the rotting problem an experiment was conducted in the Dept. of plant pathology, Institute of Agricultural Science, SOADU, BBSR. To avoid the post-harvest loss due to Colletotrichum spp different plant extract, Bio control agent and some chemical control was tried in the lab condition. Among plant extract, Onion (Allium cepa), Garlic (Allium sativum), Sadabahar (Vinca rosea), Begunia (Vitex negundo) plant extracts inhibited 100% radial growth of C. musae. All plant extracts inhibited 100% radial growth in 20% concentration except Bael (Aegle marmelos) and Morning glory (Ipomea sp). The Bio control agent Trichoderma hamatum inhibited 65.26% radial growth of causal fungus followed by Trichoderma harzianum (63.68%) and Trichoderma viride (61.41%). Pseudomonas fluorescens was found to be best inhibiting 100% mycelial growth. The 100% growth inhibition of Colletotrichum spp was observed by Propiconazole 25% EC, Tebuconazole 25.9% EC, Carbendazim 50% WP, Hexaconazole 5% SC, Carbendazim12% WP + Mancozeb 63% WP. But use of Plant extract and bio control agents is safe to use over ripe banana.
