Weed Management Field Day--Harrison County Pilot

Monday, June 18, 2018 - 9:30am to 11:00am
Event Type: 

The Harrison County Herbicide Resistance Project features side-by-side comparison of 10 herbicide programs in both corn and soybeans. Join us from 9:30am to 11:00am for a field walk at the corn plot (address coming soon) to gauge success and implications for future resistance management. This event is free and open to the public, and coffee and donuts will be provided.

Based on a survey conducted in Harrison County, resistance management is an important concern for waterhemp, marestail, giant ragweed, and Palmer amaranth. Samples of these weeds were collected, grown, and analyzed for tolerance to glyphosate, and results will be shared. These weeds are also being analyzed in the field-trial herbicide programs to determine the effectiveness of 10 different pre and post emergence combinations, which will be observed during the field walk.

The Field Walk will be held rain or shine. In case of rain, call the Harrison County Extension Office at 712-644-2105 to confirm location details; the rain location will be Agriland FS, 404 S. 3rd Ave, Logan, Iowa. While this field walk is free and open to the whole family, your RSVP helps ensure adequate space and food. Please RSVP to Carter Oliver at cpoliver@iastate.edu or 712-644-2105.
