Several have posted about my poision ivy delema, and thanks, I appreciate your response. However, several mention Roundup as an ivy killer, but I've never had any luck with Roundup on broad leaf grasses or ivy. I do have great results with Weed-B-Gone, Wipeout, and Brush-B-Gone. I even mix several herbesides with Roundup along with a little detergent. It kills everything it touches. But, Roundup alone for broad leaf plants doesn't work for me. And I do use the concentrate.
