Occurrence and distribution of Fusarium graminearum and deoxynivalenol in sweet corn ears.

Unusual wet and cool weather conditions during the 1994 growing season in Maryland and Delaware resulted in a severe outbreak of Fusarium graminearum on sweet corn ears (‘Moore’ variety) prior to harvesting and canning.  The number of ears visibly infected with Fusarium species ranged from less than 5% to 25% in some fields. Infection typically occurred at the tassel end of the ears. Infected ears were cut into four sections and the kernels only were analyed for deoxynivalenol (DON) using LC and GC/MS. Kernels from the visibly mouldy area of the ears contained DON at levels of approximately 446 µg/kg DON on average, whereas in the nonvisibly infected portion of the ears adjacent to the mouldy tips, DON levels averaged approximately to µg/kg. Sections of ears closest to the base contained no detectable DON or less than I µg/kg. This is the first reported natural occurrence of the mycotoxin DON in sweet corn prior to harvest and canning.
