Fusarium species and their mycotoxins in infected corn in Italy


Surveys of corn (infected plants and commercial kernels) forFusarium species and their mycotoxins were carried out on samples collected all over Italy and from some European and mediterranean countries.

Investigations on samples of corn stalk and ear rot standing in the field, mainly collected in southern Italy, proved to be contaminated with zearalenone (ZON), zearalenols (ZOL), and deoxynivalenol (DON). TheFusarium species most frequently isolated, and their recorded toxigenic capability (in parentheses), were:F. moniliforme;F. culmorum (ZON, ZOL, DON, 3AcDON);F. equiseti (ZON, ZOL); andF. proliferatum (MF). Along with these species,F. graminearum group 2 (ZON, DON and/or 3AcDON or 15AcDON);F. chlamydosporum;F. acuminatum (type-A trichothecene derivatives); andF. semitectum were often found to be associated.F. heterosporum (ZON, ZOL);F. solani;F. crookwellense (ZON, ZOL, FUS, NIV);F. oxysporum (MF);F. avenaceum (MF);F. sporotrichioides (T-2 toxin and derivatives); andF. poae (DAS, MAS) were occasionally isolated.
