Hi everyone
I have a small 3/4 acre vineyard I inherited from my father-in-law. This is my 3rd summer and I'm having a problem with what I think is downy mildew but I'm not sure. I've attached a couple pics of the leaves. I have four varieties of wine grapes... Marquette, Foch, Chambbourcin and Chancellor. I'm mostly having an issue with one variety. It's either the Chambbourcin or Chancellor... my FIL didn't document which is which.
I've sprayed 3 times this season:
6/3 - Captan 50 and Rally
6/20 - Captan 50 and Sovran
7/2 - Captan 50 and Rally
Is that downy mildew I'm getting hit with? Should I be doing something different?
Thanks for any ideas!
