Alternating chemistries still a plus for weed control

Dr. Larry Steckel, Tennessee Extension weed scientist, discusses reasons to change chemistries.

Weed scientists have long recommended not applying the same herbicides twice in a row.

Research at the University of Tennessee is indicating there’s another good reason to change chemistries even when they’re in dicamba-resistant crops.

The University of Tennessee’s Larry Steckel explained why in a presentation at The Pesticide Stewardship Alliance Conference in Memphis, Tenn., earlier this year.
