roundup mixed 50 / 50 with poision ivy killer, it will be dying by the next morning, its amazingly effective

I haven't tried that mix, but, do you really want it dying by next morning? If it's really toxic it kills the leaves before it gets into the system. I want it absorbed by the leaves, and spread to kill the whole plant, and usually that takes a bit more time.
