ABSTRACT:A study based on isolation and pathogenicity test was conducted to determine the fungi associated with spoilage of stored and marketed white yam tubers (Dioscorea rotundata) in Umunede for effective control. Fungi isolated were Aspergillus niger,Penicillium sp., Fusanum sp. and Rhizopus nigricans. A niger and R. nigricans were the common fungi associated with the dry and wet rots respectively of the yam tubers. All the fungi were pathogenic on the white yam tubers cultivars in this study. Penicilium sp was more pathogenic than the rest isolates.
