Handy Bt Traits Table Updated (05/30/19)

The Handy Bt Traits Table for U.S. Corn Production was updated by Dr. C. DiFonzo at Michigan State University to include the ‘breaking news’ about Bt resistance in European corn borers and northern corn rootworms.

The Handy Bt Traits Table for U.S. Corn Production was updated by Dr. C. DiFonzo at Michigan State University to include the ‘breaking news’ about Bt resistance in European corn borers and northern corn rootworms. A new column called “Resistance confirmed to the combination of Bts” was added to the table to indicate field failures, confirmed resistance or cross resistance for each insect pest. This table serves as a general guide to which Bt traits may have potential resistant problems to certain insect pests. Growers, seed dealers and ag consultants can then select the best Bt trait for pest management in their local area. To download The Handy Bt Traits Table, see the website below:
