A survey was carried out during 2004 harvesting season in five agroecological zones in Nakuru and 4 agroecological zones in Nyandarua district. Fusarium species were isolated from wheat kernels and were identified based on cultural and morphological characteristics. Mycotoxin content in the wheat grains was determined by direct competitive Enzyme-Linked Immunosorbent Assay.The major fungal genera isolated from wheat grain samples were Epicoccum, Alternaria, Fusarium, Aspergillus and Penicillium. Fusarium species isolated were F. poae, F. chlamydosporum, F. oxysporum, F. graminearum, F. equiseti, F. moniliforme, F. avenaceum, F. semitectum, F. crookwellense, F. lateratium, F. sporotrichioides, F. scirpi, F. sambucinum and F. solani.Most of the wheat grain samples were contaminated with mycotoxins deoxynivalenol, T-2 toxin and zearalenone. The incidence and levels of the mycotoxins varied in samples from different agro-ecological zones.The study showed that Fusarium head blight pathogens are highly prevalent in the wheat-growing district of Nakuru and Nyandarua.
