Preharvest accumulation of deoxynivalenol in sweet corn ears inoculated with Fusarium graminearum.

Three types of commercial sweet corn hybrids (sugary (su1),shrunken or ‘supersweet’ (sh2) and sugary enhancer (se1)) were silk channel inoculated wthe a macroconidial suspension of Fusarium graminearum and the accumulation  of DON in kernels was monitored. On all hybrids, disease symptoms were apparent 4 days after inoculation. Toxin levels were greater  1 mg/kg in kernels as early as 2 weeks after silk emergence and rapidly increased to extremely high levels. Susceptibility in all hybrids decreased as the silk dried out. DON concentrations were concentration were correlated to disease severity. There were correlated to disease severity. There was some indication that the sh2 genotype was more susceptible than the  su1 or sel1 genotypes.
