Kudzu is a very nasty imported plant that is considered environmental damaging. It was imported to use as a ground cover after highway construction after WWII. It is however, extremely invasive and is taking over vast amounts of southern land by choking out the native plants to include trees. Very few herbicides are/have been effective in controling this nightmare.

He would probably get a medal for killing any of it from the Serria Club, the EPA and USDA. IT's very tough and nearly human resistant.
