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.
