Revised Michigan State Handy Bt trait table available

by Bruce Potter, IPM specialist

Most corn hybrids contain at least one transgenic trait for insect or weed control. When it comes to Bt traits, remembering which Bt event does what can be challenging. Dr. Chris DiFonzo, field crop entomologist at Michigan State University, has revised her reference for Bt traits in corn to help keep things straight.

The recently updated 2018 Handy Bt Trait table is better than ever. It lists which insects a particular Bt trait or pyramid of traits is expected to control (for example, corn rootworm or black cutworm). It also lists herbicide tolerances and refuge requirements.
