Abstract Twenty-five samples of maize kernels collected at harvest time from geographically different corn fields in Peru, were examined for the occurrence of toxigenicFusarium species. The most frequently recovered species wereF. subglutinans (48%),F. moniliforme (46%), andF. equiseti (5%). OtherFusarium species isolated (up to 1%) includedF. graminearum, F. acuminatum, F. solani, F. oxysporum, andF. culmorum. Assays ofFusarium culture extracts usingArtemia salina larvae, showedF. subglutinans as one of the most toxigenic species, and its toxicity was mostly correlated to the capability to produce beauvericin (BEA). All eight tested isolates ofF. subglutinans grown on autoclaved corn kernels produced BEA (from 50 to 250 mg/Kg) as well as moniliformin (M) (from 70 to 270 mg/Kg). This is the first report on BEA and M production by maize isolates ofF. subglutinans from South America.
