Nine microorganisms were isolated from four varieties of Dioscorea rotundata (gbongu, ogoja, Amula, Hembamkwase); four bacteria, Erwinia carotovora, Pseudomonas aeruginosa, Serratia marcescens, Klebsiella oxytoca and five fungi, Rhizopus stolonifera, Aspergillus niger, Aspergillus flavus, Fusarium oxysporum, Penicillium marneffei, from five local government areas of Benue State (Vandeikya, Ukum, Katsina Ala, Guma and Logo). Pathogenicity test on the isolates confirmed them to be the cause of rot. The nine plants extract (Ceiba pentandra, Jatropha tanjorensis, Azadirachta indica, Moringa oleifera, Carica papaya, Mangifera indica, Daniella oliveri, Terminalia catapa and Passiflora edulis) synergistically added inhibited all the four bacteria isolates completely. The five fungi were inhibited by 60% (c) - 80% (b); Rhizopus stolonifera, Aspergillus flavus, Fusarium oxysporum; and Aspergillus niger, Penicillium marneffei, respectively.
