Learn what you can do now

Herbicide-resistant weeds are increasing in Nebraska. Uncontrolled horseweed, kochia, giant ragweed and waterhemp are becoming an all too common sight in commodity crop production.

To help combat the issue, UNL Extension weed scientists will offer four workshops on new tools to battle weed resistance.

These “hands-on” workshops will demonstrate how to use the Herbicide Site of Action Numbering System in the 2013 Guide for Weed Management Guide for Nebraska and cover these topics: 

• herbicide tolerant crops,
• how weed resistance develops,
• overview of weed resistance in the Midwest and Nebraska, and
• examples and practical solutions for major weed resistance cases in Nebraska.

Workshops will be held at:

• Norfolk — March 18, Life Long Learning Center, Northeast Community College.
• Auburn — March 19, Nemaha County Fairgrounds.
• Ogallala — March 20, Valentinos Pizza meeting room.
• Alliance — March 21, Alliance Learning Center.

Speakers will include UNL Extension Specialists Greg Kruger, Bob Wilson, and Stevan Knezevic at Ogallala and Alliance, and Amit Jhala, Lowell Sandell, and Stevan Knezevic at Norfolk and Auburn. Extension Educators collaborating with the workshops include Gary Lesoing, Doug Anderson, and John Thomas.
