One of the biggest challenges today in modern crop farming around the world is weeds increasing resistance to herbicides. Here in North America this issue has come full circle in not only where glyphosate has been primarily used, but also in other cropping environments using other chemistries.

This webinar will explore the current situation with herbicide resistance in North America, discuss some smoking guns out there that are increasing the problem, and some strategies for farmers to incorporate on their farms to combat this on going challenge.
