The science of weed control will be the main topic at the July 1 Weed Science Field Day at Iowa State University’s Curtiss Farm. Crop producers, consultants and others involved with the crop industry are encouraged to attend and learn research-backed methods to improve weed management on the farm.  

The Weed Science Field Day is organized by the ISU Extension and Outreach Weed Science program. The event will feature research updates from the program, in-field educational sessions and demonstrations on herbicide resistance management, herbicide programs and herbicide application technology.

“Crop producers and consultants will have the opportunity to see first-hand a wide range of herbicide programs for both corn and soybean, and discuss the current status of resistance and management strategies for 2026,â€� said Wesley Everman, assistant professor and extension weed specialist at Iowa State. “This year’s field day will also include special sessions dedicated to spray technology and applications with our ISU Digital Ag group.â€�  

The Weed Science program, led by Everman, has approximately 60–70 herbicide evaluations and weed control trials planned this year, evaluating new and existing herbicides for weed control in corn and soybeans.

Check-in starts at 8:30 a.m., and the program begins at 9 a.m. with a welcome from Everman and Jason Henderson, vice president for extension and outreach with Iowa State. In-field sessions will commence at 9:30 a.m., followed by a complimentary lunch at noon.

Additionally, Certified Crop Adviser continuing education units will be available for participants.  

The Curtiss Farm is located at 2219 State Avenue, Ames. Signage will be posted to help direct attendees to the plots.  

The event is offered at no cost, but participants must RSVP by June 24. Registrations are accepted online or by contacting Meaghan Anderson at mjanders@iastate.edu or 319-331-0058.
