Herbicide guide available on ISU website
The 2013 Herbicide Guide for Iowa Corn and Soybean Production can be accessed at www.weeds.iastate.
edu. The publication provides an update of new herbicide products, as well as a effectiveness chart for herbicides used in soybean and corn production.
“Herbicide site of action and injury symptoms are described and information about herbicide group numbers is included,” says ISU Extension weed specialist Mike Owen. “A list of prepackage mixtures of herbicides is included. The current herbicide-resistant weed situation in Iowa is described, and a discussion about Palmer amaranth is provided.”
If you have questions about the Iowa State University annual weed publication, WC 94, or any weed management issues, contact Owen at firstname.lastname@example.org or ISU Extension weed specialist Bob Hartzler at email@example.com.
If interested in weed management, you are encouraged to participate in an online survey. Owen says the survey is being conducted among Midwest corn and soybean growers. “This survey is looking at the impacts of glyphosate-resistant weeds and changes that are occurring in weed management as a result of the increase in occurrence of glyphosate resistant weeds,” he says.
“Information on adoption of cultural management techniques to help manage these weeds is of great interest. The survey is only 12 questions, and the information gathered will be most helpful in understanding weed management perspectives.”
Results of the survey, at www.surveymonkey.com/s/59GJBCX, will be given at Weed Science Society of America meetings.
