If the vines are in an area where you can spray, then just spraying
with 3% Roundup will work. Or you can cut and then treat the new
growth with Roundup or one of the similar products made for weeds and
brush. They are cheaper and more effective than triclopyr, which is a
selective herbicide.

I doubt a 3% solution of Roundup will kill such a mature vine.

Either herbicide will work. But I'd still recommend tryclopyr. It's
selective, as the googlegrouper said, but it's selective towards woody,
broadleaf plants (exactly what you're trying to kill).
