AMES, Iowa — Iowa State University Extension and Outreach will host a herbicide resistance management field day on June 29, from 1-3 p.m. at Iowa State University’s Northern Research Farm (south farm) located one mile south of Kanawha on R35 or 1040 James Ave.
This field day will promote effective management of herbicide resistance through known principles of using effective herbicide modes of action, effective rates and appropriate timing strategies.
“Farmers will get a good look at the use of multiple strategies to combat weeds, not just chemicals, but cultural practices as well,” said Angie Rieck-Hinz, field agronomist with ISU Extension and Outreach.
Effectively managing waterhemp is becoming a bigger challenge due to the development of multiple herbicide resistant populations. In addition, the use of a cereal rye cover crop with different termination timings and narrow-row soybeans will be used to demonstrate weed suppression strategies.
Rieck-Hinz and Meaghan Anderson, both extension field agronomists with ISU Extension and Outreach, will lead participants through soybean herbicide plots to evaluate principles of managing herbicide resistant weeds with both chemical and cultural control.
This field day is free and open to everyone. Certified Crop Advisors can receive 2.0 pest management CEUs for attending.
For more information, contact the ISU Extension and Outreach office in Hancock County at 641-923-2856.
