Handy Bt Trait Table for U.S. Corn Production
The original Bt trait table has a column titled 'Resistance to a Bt protein in the trait package has developed in:' to highlight insect x Bt combinations with documented field-failures, confirmed resistance, or cross-resistance. These statements are based on published lab assays &/or field research. This view of the Bt Table is intended to alert growers and consultants to potential management problems, influence seed selection, and encourage field scouting. Citations for resistance statements can be found here.
