The Harrison County Herbicide Resistance Project features side-by-side comparison of 10 herbicide programs. Join us from 10:00am to 1:30pm at the soybean plot to gauge success and implications for future resistance management. This event is free and open to the public. Thank you to Farm Credit Services of America for providing lunch; Cattlemen's Association will be grilling.
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 in the field.
Join us at Larry Buss Farm, Approximately 300 feet west of the intersection of US highway 30 and Niagara Trail South about 2 miles southwest of Logan. This field day 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 the Logan Community Center, 108 W 4th St, Logan, Iowa. While this event 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.
