ABSTRACTGrain samples of sorghum were collected from Nigeria, Lesotho, and Zimbabwe from grain sold in markets, left unharvested in the field, and stored in home storage units. The most prevalentFusariumspecies isolated wasF. moniliformewhich accounted for 65.2% of the totalFusariumspecies recovered. Other species isolated wereF. equiseti(8.9%),F. semitectum(8.4%),F. nygamai(7.5%),F. chlamydosporum(4.5%), andF. graminearum(3.7%). Other species isolated infrequently wereF. compactum, F. solani, F. proliferatum, F. dimerum, F. avenaceum, F. sporotrichioides, F. lateritium, F. sambucinum, F. napiforme, F. oxysporum, andF. subglutinans, these species accounting for 1.8% of those recovered.Fusarium moniliforme, F. equiseti, F. nygamai, andF. semitectumwere recovered from samples from all three countries.Fusarium graminearumwas recovered from samples from Nigeria and Zimbabwe but not from samples from Lesotho.Fusarium moniliformeandF. nygamaiare known to produce fumonisins, some of which are carcinogenic. The recovery of isolates ofF. sporotrichioidesfrom a sample from Nigeria was unexpected since this species is usually found only in temperate to cold regions.
