Determining what Bt traits are in each corn trait package can be a challenging task. Fortunately, Chris DiFonzo at Michigan State University has streamlined the process by creating the Handy Bt Trait table. The Handy Bt trait table has the trade names for the currently available trait packages, what Bt toxins are present in products, what insect pests they manage, refuge requirements, and the corn’s herbicide tolerances. The most-recent version and information on how to use the table can be found on the The Official Handy Bt Trait Table for U.S. Corn Production website, or by clicking or tapping the blue button at the end of this article.

As a reminder, it is recommended to rotate Bt toxins for managing corn rootworms. Furthermore, at SDSU Extension, we do not recommend using a single Bt gene for corn rootworm management and pyramided genes (two or more genes) should be rotated for both continuous and rotated corn.
