Where can I find someone qualified to use herbicides properly?

Asked September 23, 2019, 4:33 PM EDT

The question above pertains to my yard. The DNR advised me to use particular herbicides on Canadian Thistle, Leafy Spurge, and another crown vetch. I don't want to handle all of those chemicals myself. The two lawn care companies I called claimed to know more than the DNR. So, I need to look elsewhere for help. I left the same question by voicemail. But, the recording says that VM takes up to 4 days for a reply, whereas online takes only one (the website says 2.) Thank you! Ellen

I don't know what herbicides the DNR suggested, nor do I know what your lawn care companies recommended. But I will say this: lawn care companies are licensed to use a different set of (and stronger) chemicals than homeowners. That might explain the difference. The DNR was advising a homeowner on what he or she could use, which would be different than the palette available to a lawn care company.

If you decide to DIY, please read and follow the label of all pesticides you use. Here is a reference on controlling various weeds:

Crown vetch is not in this list, so look here:
