There are numerous Bt traits available in corn seed that can vary year to year, leaving growers overwhelmed when choosing a seed to purchase for their farm. Thanks to Michigan State University colleague, Dr. Chris DiFonzo, a "Handy Bt Trait Table" is available to assist with this complicated decision. Thanks to Dr. DiFonzo's efforts, the Bt Trait table is now in it's 18th year of publication. If you have any questions or comments should be directed to her(firstname.lastname@example.org or 517-353-5328).
