Can you help me identify this grape leaf disease and how I can prevent it?

Similar problems for my two grapes at San Diego, California. See the two photos. We used some insecticides, so far not much help.

Would appreciate any suggestions. BTW, could not find a grape forum, see posted here.

Look up Botryis...

Grape leaves are notorious for this and I think there are plenty of good systemics or topicals for this,,I would call a grape vine grower how they deal with it or what safe product they use or ask in this in the disease forum...

sulfur dusting is the simplest control; most commercial vineyards do it often during the growing season.
