Poison Ivy / Thistle Vine

I have 2 situations that I would very much appreciate your advice/thoughts on.

1) A customer has thistle vine growing on oak trees in the lawn that they would like killed in order to make a landscape bed under the trees. I need to kill the vines that are growing on the trees, without hurting the trees. Recommended chemicals and application technique?

2) A customer has an 8' tall chain link fence that poison ivy has used to grow a large 10' tall hedge about 4' wide. About 5ft away from the poison ivy hedge, there is a row of junipers running parallel to the fence. I need to kill the poison ivy and not injure/kill the junipers. Recommended chemicals and application technique?

Thank you in advance for your replies.

Poison Ivy and our other invasive weedy vines are not easy to kill and require non-selective herbicides. Finale is really the best all around weed killer for drought tollerant plants glyphosate can't hurt. I have been using Finale for ten years. I think it's off patent protection and the price has dropped to about $150 at BWI for a 2 1/2 gallon jug that makes about 106 gallons of mix.

Vines have a weak point. If you cut them off at the ground level and separate the roots from the top...they die promptly. Of course, then they sprout from the roots. Then spray the new sprouts; try to kill them before they get more than 6 inches tall.
