weeds in soybeansAMES, Iowa – Iowa State University Extension and Outreach will host a herbicide resistance management field day June 25, 5:30-7:30 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 become a major problem.

Attendees will learn about effective herbicide sites of action, weed control for both individual herbicides and a full program approach and the impact of timing and herbicide program approaches to weeds in soybean.

ISU Extension and Outreach field agronomists Meaghan Anderson 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, with signs directing to off road parking. Certified Crop Advisors can receive 2.0 pest management CEUs for attending.

Please contact the ISU Extension and Outreach Story County office at 515-382-6551 with questions.

Quote 1 Transcript. Narrator: The herbicide resistance management field day that we’re hosting south of McCallsburg on the evening of June 25 is really a very unique opportunity for farmers to actually come out and look at herbicide programs in soybean for the purpose of managing waterhemp where we can actually show them what individual herbicide components of their program might be doing to manage water hemp, as well as like a full program approach. And it’ll be a neat opportunity for them to kind of evaluate how their program might stack up against some that we have put together, and what they might want to do to manage resistance in the future.

Quote 2 Transcript. Narrator: I think the most important thing that farmers need to know about herbicide resistance management is that herbicides alone cannot solve the resistance problem, but their a hugely important part. And so, I think farmers can do really good job of keeping their weed pressure down by better managing the herbicides they have in their portfolio right now. So at this field day we’re going to talk about managing individual herbicide components of a program, what an entire program looks like, what’s the importance of rate and timing with regard to managing waterhemp. And I’m hoping that we can bring all that together and make it really obvious to farmers that herbicide programs need to be finely tuned to manage their problem weeds that they have.
