Grapes have a blight
Our grape clusters have grapes that are turning brown and molding. Possibly black rot but grapes aren't shriveling. We've been cutting them off and disposing of the diseased ones. How do we prevent or get control of what's happening? We are using a copper sulfate fungicide but didn't start at blossom time. Help please. We don't want to lose the whole crop. Thanks.
