I on my grapes have some what I think is some sort of rot. Starts out in a small brown circle then goes thru the leave then curls up and the leave seems to die off. I want to keep everythink as organic friendly as I can.
Thanks

Sounds like you have black rot. I have used a couple of things for that on my grapes.Serenade is one of them and yucca extract is another.Both are organic options.Since yours sounds like a bigger problem I'd try the yucca, it seems to have a quicker response on an active outbreak.I bought mine from peaceful valley.Its trade name is thermx70.
