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.


Have you ever tried it? I've routinely used it on mature poison ivy
and it works very well. On ground based poison ivy, I just spray it on.
If it's a large vine going up a tree, with no accessible leaves, I cut
it, wait till new growth emerges, then spray it a month later. Never
had to brush it on.

In my experience the broad spectrum total vegetation type killers have
always been more effective than a selective herbicide, where there is a
tradeoff on what it will and won't kill. For example, triclopyr is
used for clover control in lawns. It usually takes at least two
applications to control it. The first tends to just stunt it. If you
sprayed that with Roundup or another total vegetation killer, it would
be dead the first time, but so would the grass.

As to the OP's question of future planting following Roundup, it's safe
to replant a week after application.






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).
