The symptoms were Anthracnose, Alternnaria leaf spot, Boll rot, Cercospora leaf spot, Rust, Sclerotium rot and Wilting. Present study revealed that association of 30 species of fungi which belonged to 21 genera such as one one in Zygomycetes, one in Ascomycetes, one in Basidiomycetes, 18 in Deutermycetes and one in sterile fungus. The isolated fungi were Alternaria alternata (Fr.) Keissler, Arthrinium sp., Ascochyta sp., Aspergillus flavus, Link., Aspergillus niger Van Tiegh, Aspergillus sp., Botryodiplodia sp., Cercospora sp., Chaetomium sp., Chaetophoma sp., Cladosporium sp., Colletotrichun coffeanum Noack, z. f. Pflan zenko., Colletotrichum spp., Curvularia clavate Jain, Curvularia lunata (Wakker) Boedijn, Fusarium moniliforme, Wr. and Reink, Fusarium spp., Nigrospora sp., Pestalotia sp., Penicillium sp., Phoma sp., Pteroconium sp., Puccinia sp., Rhizopus stolonifer (Ehrenb.
