UNL Weed Scientists on Weed Resistance

Although it has been getting more attention the last few years, the issue of herbicide resistant weeds is not new. In this video retired UNL weed scientist Alex Martin discusses some of the history of weed resistance and how we got to where we are today. Chris Proctor, a current UNL weed scientist, highlights some of the present-day issues with herbicide resistance management.

Both note the importance of diverse weed management techniques to slow the spread of herbicide resistance and the significance of thoughtful stewardship of our herbicide technologies to ensure their usefulness into the future.
