Updated Handy Bt Trait Table

Bryan Jensen

Dr. Chris DiFonzo, Field Crop Entomologist from Michigan State University, has updated her Handy Bt Trait Table. I’m sure most of you will find keeping track of Bt traits and their spectrum of control to be confusing at best. Chris has updated two tables that will help considerably. The first table identifies the event name, specific protein(s) expressed and general control spectrum for each trade name. She also breaks down each trait family and identifies specific Bt proteins express, insects controlled or suppressed as well as refuge requirements.
