There is a product on the market called "Brush b gone" that i use in these situations. The active chemical ingredient is Trycloper(sp?) at about 8%.
I start By cutting through the main stem of the poision ivy a couple feet from the ground then I score the vine(leading back to the ground) in several places(like the round-up label suggests) and paint on the brush b' gone full strength being carful not to drip any in the process. It has worked the first time in most instances. When the top potion of the vine dries up a little i pull it down out of the tree. This stuff is in-expensive and a little goes a long way.

I had great success several years ago waiting till August and or September.........spray with Super Trimec.


August and September......the vine is translocating sugars down to the roots.

What about the product "Vine-X" that I see advertised in garden centers? http://www.vine-x.com/vprod.html

It looks like a triclopyr formulation and is labeled for poisen ivy.
