3 reasons to attend Weeds Week event in Iowa

ISU's Weeds Week 2016 program will focus on herbicide resistance and weed management planning.

The second annual Weeds Week series on herbicide resistance and weed management will take place July 18 to 22 across Iowa. These one-day programs, tailored to farmers and ag chemical retailers, will be held in five locations: Crawfordsville, Lewis, Nashua, Sutherland and Boone. The program is sponsored by Iowa State University Extension.

SEE YOU THERE: Weeds Week is an ISU Extension program for farmers and ag chemical retailers that will be held in five locations across Iowa next week. These one-day programs will help farmers develop effective weed management strategies.

“Our goal is to help farmers develop effective weed management plans,” says Virgil Schmitt, a field agronomist for ISU Extension. “Sessions have been developed to provide tools that help farmers and agribusinesses work together to develop long-term weed management plans that identify sites of action, promote timely application of herbicides and avoid the expenses of dealing with herbicide resistance.”

1. Hands-on weed management planning and discussion
Each session will include presentations, hands-on weed management planning, small group discussion and plot tours presented by ISU Extension field agronomists. Attendees will learn how to select herbicides from the herbicide effectiveness table, identify which herbicides to apply and develop their four-year weed management plans for their operation or for customers.

Kellie Blair of Dayton, Iowa attended Weeds Week in 2015 for more of a refresher course, while her husband AJ attended the program for the herbicide use and management information. “For me, it helped with weed identification and what modes of action are out there,” says Kellie Blair.

Blair says the Weeds Week program she attended at Boone, Iowa reminded her and her husband not to go with the easiest option of herbicide mixes, to look at and understand herbicide labels, and to make sure that the herbicide and application matches up with the weed pressure.

2. Weed control is now a more complicated decision process
“When my husband and I started farming, weed management was pretty simple,” said Blair. “But now, it’s a more complicated program. Weed pressure has gotten worse the last couple of years, so it was beneficial for us to hear information about using appropriate herbicides and doing timely applications for a successful outcome.”

Each location will have a 9:30 a.m. check-in time. The program will begin at 10 a.m. and conclude at 3 p.m., with lunch served at noon. The $25 registration fee includes lunch, refreshments and course materials and publications. Attendees are asked to pre-register to assist with facility and meal planning.

3. Evaluate your weed control this summer
“Now is the time to evaluate how your weed management worked this year,” advises Meaghan Anderson, an ISU Extension field agronomist. “Rather than falling back on old habits, analyze your program closely to look for improvements for future years.”

Rainfall has been highly variable across the state, likely resulting in differences in both weed emergence and herbicide performance. Southeast Iowa seems to have no shortage of waterhemp that made it through early-season residual herbicide applications. Surviving weeds from this year will affect weed pressure in next year’s crops. “Excellent notes from this summer and fall will make herbicide purchase decisions easier in the wintertime,” she says.
