Description:
A significant increase in genetically modified corn planting driven by biofuel demand is expected for future growing seasons. As demand increases, incidence of farmer non-compliance with mandated non-genetically modified refuge is likely to increase. As part of the FIFRA registration’s terms and conditions, seed producers of genetically modified corn expressing the plant incorporated protectant Bacillus thuringiensis (Bt) are required to implement and provide information to the U.S. Environmental Protection Agency (EPA) on integrated resistance management (IRM) programs for genetically modified crops. Long-term sustainability of genetically modified corn expressing Bt relies on the validity of assumptions underlying IRM models used by the EPA and the ability of EPA to monitor, detect and react to insect resistance when it develops. The EPA is developing a multi-tiered approach that utilizes satellite and airborne remote sensing to locate and monitor genetically modified corn in the agricultural landscape and pest infestation. The current status of the EPA IRM monitoring program and remotely sensed imagery acquired from multi-spectral satellite and airborne hyperspectral sensors for use as a decision support tool will be discussed.
