Chocolate vine - diseased?

My neighbour has a chocolate vine growing up the fence which is coming over the top. I think it's pretty so I've been winding it into the trellis on my side as it appears!

Unfortunately, some of the leaves have developed black spots and the vines have a sort of powdery fungus. I've cut off the affected vines.

Was that the right thing to do? Is there anything I can do to treat it or is the problem on my neighbours side?

    It looks look like Powdery Mildew to me. I would say that is more growing conditions and atmosphere and could change from year to year. It's possible that there is poor air circulation and over-crowding. The soil may be very dry but, cutting out growth doesn't always control it. It's a case of finding out what is happening on the other side of the fence. Good mulch and watering can minimalise it, and collect and remove all fallen leaves at the end of the growing season is important on your side as well as your neighbour's  side.
