Late-Season Weed Escapes in Wisconsin Corn and Soybean Fields
The potential increase of glyphosate-resistant weeds is a major threat to corn and soybean production across the Nation. Integrated Weed Management tactics, including diversified herbicide use, are important components of management to delay the onset of glyphosate resistance. Identifying geographies that may be most vulnerable to resistance development could help direct attention and pro-active resistance management tactics before wide-scale control failures occur. To help with this, the University of Wisconsin-Madison Field Crops Weed Science Extension program is asking for your participation in a research study investigating the weed species diversity in Wisconsin Corn and Soybean fields due to reduced atrazine use and subsequent increased use of glyphosate. The purpose of this research is to identify areas in the state where there may be a shift to weeds that are more difficult to control with glyphosate, or where weeds that are resistant to glyphosate may first appear.
This survey asks questions about target weed species and limited management history information relating to crop production fields. There are two levels of participation in this survey. The first level simply includes filling out an on-line survey with information from ONLY ONE CROP PRODUCTION FIELD per survey form. If you are willing to provide information about more than one field, please repeat the survey. The second level of participation, if you would please participate further, is to allow weed science research staff from the University of Wisconsin-Madison to survey your crop fields for weed escapes in late-summer months.
We expect the survey to take only 5 to 10 minutes of your time, and we don’t anticipate any risks to you. For fields we scout for weed escapes in the late summer, we will provide a detailed weed scouting report to participants.
You may ask questions about the research at any time by contacting Vince M. Davis at vmdavis@wisc.edu (608) 262-1392 or Ross Recker at rrecker@wisc.edu. Your participation is completely voluntary. By completing and electronically submitting this survey, you consent for participating in the first stage of the survey. If you would like to participate in the second stage, and allow UW weed science researcher to scout your production fields, please complete the last question of the survey by providing your contact information.

We THANK YOU in advance!
