How do you get rid of burdock plants in a field?

I would be most happy to remove your burdock from your field ... where do you live? Suzanne McDaniel, RN floridawings@aol.com

The Catskill Mountains upstate New York. They take over some of the fields up here. Mow them down and they seem to grow back thicker! Alfred TruesDELL, truesDELLa@aol.com
