Indirect reduction of ear molds and associated mycotoxins in Bacillus thuringienisis corn under controlled and open field conditions: Utility and limitations.

Ears of an experimental inbred corn (Bt) containing a synthetic Bacillus thuringiensis Cry IA(b) gene that were inoculatedwith Aspergillus flavus and Fusarium proliferatum or exposed to natural mould inoculum after infestation with Ostrinia nubilalis (Hubner) larvae were found to be free of visible signs of mould. Approximately 30 – 40 % of the non –Bt ears similarly treated wee visibly infected. Results in the following year using the same inbred with a single allele dose of the Bt gene showed similar trends. Mean total fumonisin levels for non – Bt versus Bt inbred ears were not significantly different (2.8 versus 0.8 mg/kg, respectively).
