This vine appeared 2 years ago here in NY. I didn't pay too much attention to it until it started to grow over desirable plants

can see the vine starting to grow at lower left, center, and lower right. Since then, i have started to pull the vines whenever I saw them. The vines are shallow rooted so they pull out of the ground easily. They have tiny thorns along the stem, so if you have callous hands, as I do, they can be pulled bare handed, otherwise use gloves. It's name is Persicaria Perfoliata, or Mile-A-Minute Link to description of plant.
