I have a very old concord grapevine that for the past two years has had a disease that causes a black spot on the grapes before it ripens and before it can ripen all the way, they shrival up and die. I have sprayed it with organic spray, but, it seems not to be strong enough. Any suggestios? I really use the grapes for canning. Thanks

It would help if you posted some pictures showing any symptoms, like spots of leaves.
Thankyou so much HydroPinke! That is exactly what has happend the last two yrs. It has helped me so much. Hopefully I can get it under control. Thanks again.
