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

To help combat the issue, University of Nebraska-Lincoln 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 in Nebraska.

The workshops also will cover these topics:

•Herbicide-tolerant crops,
•How weed resistance develops,
•Ooverview of weed resistance in the Midwest and Nebraska,

Marestail is one of several weeds in Nebraska that have developed herbicides resistance.

•Auburn, March 19, Nemaha County Fairgrounds
