Management of herbicide-resistant weeds will be the focus of field days August 6 at David City and August 7 at Fremont.

"Herbicide-resistant weeds are a real problem here in Nebraska.  Folks should take the time to make an investment in management practices that reduce the potential for resistance," said Lowell Sandell, a weed science extension educator.

Field day topics include: 

• Glyphosate Dose Response: See how resistant weeds respond to increasing rates of glyphosate.
   
• Management Systems: Study various herbicide programs and their effectiveness in controlling glyphosate-resistant weed populations.
   
• Liberty Link Soybean: See how Liberty Link Systems can be used to sustainably manage weeds.
   
• Dicamba-Resistant Soybean (Fremont only): View demonstrations of how dicamba-resistant soybean can provide another postemergence tool for weed management
   
• Carrier Rate: See how carrier rate impacts herbicides. This stop will also address the importance of effective herbicide applications to manage the development of weed resistance.

In addition to these topics, there will be a presentation on glyphosate-resistant giant ragweed at David City and glyphosate-resistant waterhemp at Fremont.

Each field day will begin at 9 a.m. and end at 1:30 p.m. following lunch. The event is free but preregistration is required by Friday, August 2.
