Joe Lauer, Corn Agronomist

This year there is a lot of concern among corn growers as to whether the grain of genetically modified organisms (GMOs) can be exported or even accepted by local elevators next fall. Below is a table that outlines U.S., Japan, European Union and Canada approval status of various GMO events. Corn hybrids that DO NOT include GMO events are high-oil corn, IMI corn, white corn, and waxy corn.
