We had the same question, and the advice from Garden Exchange was to use Crossbow. It's about $40 a quart, put it on the freshly cut stumps. Can also get that from Farmers Co-Op or CPS. It will help to get a little Turf Trax blue dye so that you can remember where you've been. Mix them in a little squeeze bottle, only a tablespoon of the blue stuff is enough for color, and put it on the freshly cut stumps (needs to be freshly cut in the past few hours or else the cambium will seal up, stop feeding the roots, surface poison would be ineffective). So far so good for us. We did miss a few, and they grow back thicker than the original tree, they like to sprout in all directions from a cut stump, so you'll get 10 thin trees looking like a bush where you once had a tree. Also, the stuff you have in your cut piles will start to send down roots and sprout towards the sky if you don't kill it somehow. Good luck.
