I use Trimec Classic broadleaf Herbicide I had got from a fertlizer plant it comes in a gal bottle 1 cup to a 6 gallon sprayer. it goes a long way It will kill the plant above ground for now but in the fall is when you need to apply when the plants are takeing every thing back to it roots I have been fighting this for two years I have it just about gone. In early early spring use a hard rake and pull as many vines as possible up and get rid of them I burn them on a big fire stay a way as they burn good luck |
