For larger trees you can drill a hole at a downward angle with a large bit, no higher than 18" above soil level. Then inject the herbicide. An old dishwashing liquid bottle can be used for this. This method keeps the herbicide away from all non-target plants and out of the soil and air. It also uses very little herbicide while being very effective. I tie a piece of red surveyor tape around the treated trees, so I know which ones I already did.
The first sign that the method works is that all the leaves will fall off. The herbicide will work its way through the tree's system, so that any fruits on it will be unable to reproduce. Eventually the tree will dry up and fall over, and you can pull it up roots and all leaving no unsightly stump to trip over.
I use Ortho poison ivy killer, which comes in a pint bottle for $12-13. Dilution is 1/2 cup to 1 gal. water, so it goes a long way.
