May 10, 4:00pm - Applied Abound 2.08F to all vines in our new vineyard
(in North Alabama)

May 10, 4:15pm - Left to go out of town for weekend

May 10, 5:00pm - Mother nature dumped .75 inches of torrential
rainfall on still wet (from spray application) vines. Dang!

May 11-23 - Drought. Absolutely zero rainfall in North Alabama after
May 10 torrent..

May 13, 9:00am - Got back in town. Applied Mancozeb to all vines.
Prayed.

May 23, 3:30pm - Noticed small brown spots on periphery edges of most
varietals (see attached picture). Dang!!! Pulled out some hair.
Started to drink.

Looking for positive identification of disease of what to do moving
forward. Symptoms are apparent on many leaves making it impractical
and risky to defoliate since these are first-year vines with little
vegetation.

What to do? Are we in trouble?

HELP!!!

Thanks,
Charles Erwin
