In the South, people have made some creative attempts to deal with kudzu. A forestry service person told me that they burn some infested forest plots to keep it under control. My favorite attempt at kudzu control is Tallahassee, Florida. They have rented a herd of sheep. They put the sheep out where the kudzu is, and the sheep eat it! Then they move the sheep to another area that needs to be de-kudzu'd. I have not heard how successful this is yet, but it's pretty fun to drive around the city and spot the sheep. While the sheep do leave some waste, Tallahassee is the capital of Florida, so people are used to wading in it.
