Grape Black Rot disease #869374

Asked May 20, 2024, 10:06 PM EDT

I live in Bemidji and have had a grape vine produce well for many years. A few years ago it started getting brown spots on the leaves that gradually turned totally brown and shriveled up. THe fruit also turns black and shrivels. Looking on line, it seems to be black rot fungus disease. I tried an anti fungal spray, but it didn't stop it. What can I do to stop this from reappearing each year?
