Biotic and abiotic factors limiting efficacy of Bt corn in indirectly reducing mycotoxin levels in commercial fields.

Incidence of insert damage and association of insert damage with mycotoxigenic fungi and mycotoxins was examined in commercial fields of Bt and non-Bt hybirds of different backgrounds. Levels of total fumonisins were generally less (15- to 1.8- fold) in Bt versus non-Bt hybrides at the same site, with some several instances where there were no significant differences in funmonism levels between low or no Bt kernel hybrids and Bt hybrides that produced high levels of proteine in the kernel and silk tissue. However, significants correlations were often noted between numbers of insert damaged kernels and total fumonisin levels. Suggesting in these cases that reducing insert damage was still reducing fumonisin levels. Although reductions in fumonisins in Bt  hybrids were more limited than reported in the past, planting the Bt hybrids still appears to be a useful method for indirectly reducing mycotoxins in corn ears.
