Handy Bt Trait Table Updated for 2023 Corn

The Handy Bt Trait Table was updated in February 2023 by Dr. Chris DiFonzo, Michigan State University. It lists information about all Bt corn hybrids commercially available in the U.S. in a concise two-page format. It presents the trade names for hybrids with Bt traits, Bt protein(s) expressed, targeted insects and herbicide traits.

The table is a useful reference to help understand which hybrids have which traits (both Bt and herbicide tolerance traits). This table can help avoid the development of resistance from using the same traits repeatedly (even if you change hybrids) and will be useful during the field season as you troubleshoot insect injury or prepare to apply herbicides.

Now in its 21th year, this table has become the standard as an authoritative reference to Bt toxins in corn. For more information, see the Bt Trait Table site.
