Bt Trait table cheat sheet available from Michigan State University

Michigan State University releases 2017 Bt trait table to help producers alert growers and consultants to potential management problems, influence seed selection, and encourage field scouting.


After the major issues with western bean cutworm in the Great Lakes region in 2016, and increasing problems with leps in the southern United States, a major change was made to the 2017 Handy Bt Trait table created by Michigan State University.  It now includes a new column ('May Be Ineffective On') to highlight insect x Bt combinations with documented field-failures, confirmed resistance, or cross-resistance. Ineffective ratings are based on published lab assays &/or field research. Check out the cheat sheet or go to Michigan State University for the latest column as it is updated throughout the year
