Fungi Associated with the Deterioration of Zea Mays L. (Maize) From Market Stores in Abeokuta, Ogun State, Nigeria

This study addressed the characterization of fungi associated with fungal contamination of maize. The diversity of fungal species responsible for maize spoilage necessitates effective control measures; however, their efficacy remains uncertain. Molecular identification of fungal populations provides essential data for predicting disease incidence and assessing potential risks. Accurate characterization of fungal species is crucial for identifying pathogenic strains in maize samples. Stored maize samples were obtained from four markets in Abeokuta- Kuto, Lafenwa, Olomore, and Osiele. Samples were labeled according to their locations. Fungal isolations were performed using the serial dilution method on Potato Dextrose Agar (PDA). Microscopic identification was based on colony morphology. molecular and macroscopic analyses confirmed 100% fungal contamination in all maize samples. The predominant fungal genera identified included Aspergillus, Fusarium, Rhizopus, Penicillium, Mucor, and Cladosporium species. The prevalence of these fungi was consistent across all the sampled locations, highlighting their widespread occurrence in stored maize from Abeokuta markets. The significance of these results were discussed.
