Objective: To investigate the occurrence and distribution of fungi associated with biodeterioration of cashew nuts (Anacardium occidentale (L.) in Kogi state, Nigeria. Methodology and results: Ware houses from four designated areas at Anyigba, cocoa research institute, Ochaja, Idah and Ankpa were surveyed for the disease incidence between 2008 and 2010. Trichoderma viridae, Cephalosporium sp and Aspergillus nigar were isolated from the diseased nuts and were identified based on morphological characters and pathogenicity tests. Disease incidence was highest in Ankpa followed by Anyigba. Conclusion: The study provides information serving as a base line in establishing these fungi being associated with cashew nut biodeterioration.
