Iowa State University has three upcoming crop clinics and field days, which will occur rain or shine:

• Monarch Conservation Summit and Field Day. The event will be from 9:30 a.m. to 3 p.m. July 13 at the ISU Field Extension Education Laboratory, 1928 240th St., Boone. Preregistration is required.

Learn about ISU field demonstrations and collaborations to promote and increase the monarch butterfly population. The population of monarchs in the eastern U.S. has declined 80% in the past 20 years, and Iowa is in the heart of the Midwestern summer breeding range.

• Harrison County Herbicide Resistance Project. This weed management field day on soybean production is 10 a.m. to 1:30 p.m. July 13 on the Larry Buss Farm in Harrison County at the intersection of U.S. Highway 30 and Niagara Trail, about 2 miles southwest of Logan.

The Harrison County Herbicide Resistance Project features side-by-side comparisons of 10 herbicide programs. Join ISU Extension crop specialists at the soybean plot to gauge success and implications for future weed resistance management. This event is free and open to the public.

Based on a survey conducted in Harrison County, resistance management is an important concern for control of 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 to determine the effectiveness of 10 different pre- and postemergence combinations, which will be observed in the field. To plan for materials, RSVP to Carter Oliver at [email protected] or 712-644-2105.

• 2018 Iowa Youth Crop Scouting Competition. This event be from 8 a.m. to 2 p.m. July 30 at the ISU Extension FEEL lab, just west of Ames on Highway 30, near Boone.

High school students (those completing grades nine through 12) from Iowa are invited to compete and show their crop scouting abilities in corn and soybean fields. The competition is a one-day event, focused on outdoor learning. Youth will scout fields for crop problems and learn about possible solutions and strategies. 

During the competition, youth will have the opportunity to interact with Iowa State University faculty, staff and agronomists, as well as professionals in crop-related careers. Prizes will be awarded to the top four teams, while the top two teams will have the opportunity to advance to the regional competition in Nebraska. Register online.
