I had a bunch of poison ivy around my back fence and this killed them on first application. I also had a bunch of vines and regular ivy growing through the fence and it killed them too. The only thing is that where the ivy or over growth is dense you may need to hit it again. I had some areas on standard ivy that it yellowed it up a bit but didn't totally kill it, but I don't know if it is ment for that use anyways. For poison ivy killing it is awesome
I can't really rate this product by itself. The reason being is that I used this product in combination with Drive XLR8 and Tenacity to nuke my yard this fall as a post emergent treatment. One thing I can say is the previous times I used Quinclorac by itself, some of the weeds survived (mainly the clovers). Not this time. With Tenacity taking care of the broad leaf, and Drive doing its job, Bonide took care of the rest. The combination of the 3 destroyed all the weeds in my yard, but left the remaining grass untouched, and ready to reclaim the yard.
