Monsanto\'s Round up continues to be the standard of the industry for systemic weed and woody brush eradication in my neck of the woods. If the vegetation to to be eliminated grows with Rhizomes thru the soil, the last thing you want to do is pick at the roots. Even the tiniest root section that has been detached from the host plant will propogate to another. Fortunately for us Ivy haters, the best way is the easiest. Spray the leaves (and stem for woody veg) and let it alone to die.
