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.
