Spray it liberally on the leaves, or paint it liberally on the cut grapevine stump. Apply Roundup to the stump within two to three hours after cutting.

Will Roundup Kill Grape Vines? Home Guides Garden Gardening. Use a hand saw or pruning shears to sever wild grape vines. Using a chainsaw is dangerous, since the grape vines are too small and unstable. Cut the grape vine again just above the ground. Cut every wild grape vine you can find, no matter how small they are.
Grape vines can regenerate quickly and easily. Remove the trunk of the grape vine and burn or shred it. Grub out as much of the root as you can with a shovel or other digging tool. Grape vines have deep, extensive root systems, and you will not be able to dig out all of it.
Mix a natural weed killer by combining 1 gallon white vinegar, 1 pound of salt and 1 tbsp. Spray this on any grape vine sprouts that re-emerge. Wild grape vine must have sunshine to grow. Or, you can dig the root out of the ground after having cut the stem at the end. Be prepared, however, because this plant has a large root system. The surest way to eradicate wild grape vine, or for that matter, any unwanted vine, is during the autumn, when they are pulling nutrients back into their roots for their winter nap.
Cut the vine at the beginning of the stem and carefully and safely paint just the cut end of the remaining stump with herbicide. Do not let the herbicide get on the trunks of your trees or anything but the vine.
Any of these control methods will work for vines growing up into trees and shrubs. There is no need to remove the vine from the trees and shrubs, since it should decay and fall away on its own.
However, if the vines have grown extensively overtaking the tree, you might try to remove vine stems from as far up as you can reach to reduce the weight on the tree. Do not pull the vines down since that will damage the branches of the tree. These runners will either have to be pulled up or smothered, or cut where the roots have anchored themselves into the ground and the cut end safely and carefully painted with herbicide. This is the situation I in which I find myself in my transition area, and I think I should tackle this task soon.
You should discuss smothering more. I have used newspaper, cardboard and materials where water cannot get through,like car floor mats. I used roofing material, under mulch, which disintegrated too fast. I neglected my garden for over a year and various vines went crazy. I used a tabletop over a difficult area. I removed it a year later. It has three snakes under it; one with a big head. That disturbed me the most. I live in an urban area. The snakes crawled there apparently during the time I did nothing.
Good point, Cindy.
