I have an old grape vine that I grow for privacy. In the last few years, I get bumps on the leaves and mildew on the underside of the leaves. It is not attractive. Any spray for this? Thx
Have we got an epidemic here?

Each "bump" has a corresponding "hairy" patch under it as opposed to general mildew. Ralph
