AMES, Iowa – Iowa State University Extension and Outreach will host a herbicide resistance management field day on June 12, from 5-7 p.m. at the A. Knaphus farm located 1.5 miles south of McCallsburg on County Road S27.
Herbicide resistance in weeds is a major challenge faced by all producers. When weeds cannot be killed, farmers are often required to apply additional herbicide or adopt different management strategies that may cost them more money. This field day aims to educate farmers on effectively managing weeds before they are a major problem.
Attendees will learn about effective herbicide sites of action, effective application rates, the impact of pre- and post-emergence applied herbicides and timing of applications. ISU Extension and Outreach field agronomists Meaghan Anderson, Terry Basol and Angie Rieck-Hinz will lead attendees through the plots to discuss herbicide principles used to manage herbicide resistant weeds.
There is no fee to attend the field day and all are welcome to attend. The plots are located on the east side of County Road S27. Due to limited visibility, attendees are asked to not park on the road, but follow the signs providing parking instructions. For more information contact Angie Rieck-Hinz at 515-231-2830.
