There were several cases where statistically significant reductions occurred. Other reductions of fumonisin levels also appear to be real based on significant correlations between numbers of insect-damaged kernels and fumonisin levels, which co-varied at the same sample locations in the field. Differences in degrees of fumonisin reductions were attributed to the timing of insect damage, species of insects present, Bt construct present, relative individual hybrid resistance to the ear mold and fumonisin production, and weather influences. Bt corn appears to offer a "quality/health protection" effect in regard to fumonisins, which is mediated by the different factors previously mentioned. |
