The Handy Bt Trait Table
was updated in January 2018. The authors include Chris DiFonzo, Michigan State University, Pat Porter, Texas A&M University, and Kelley Tilmon, The Ohio State University. It list the types of Bt hybrids present in all commercialized corn in the U.S.A. in a concise two-page format. It presents the trade names for hybrids with Bt traits, Bt event, protein(s) expressed, targeted insects and herbicide traits. It has been updated and reformatted for easier viewing.
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 trouble-shoot insect injury, or prepare to apply herbicides.
Now in its 15th year, this table has become the standard as an authoritative reference to Bt toxins in corn.
