Here in the USA we name this "Silver Lace Vine," but whatever moniker it should never be sold at nurseries. Whatever product you use, it will be more effective if you use it in Autumn. The logic for this is that right now it is drawing food reserves UP from the root system and the best you can do is top kill it. In autumn, a couple of "gentle" (meaning slightly less than label rate) applications will allow more product to be absorbed and translocated DOWN to the roots thereby getting better results. Having said this, this vine may take two or three years of repeated application to get it thoroughly eradicated. Think tenacity! Good luck!
