Grape leaf disease

Asked May 20, 2018, 1:34 PM EDT

Attached are pictures of a grape leaf disease that I cannot identify. It is for a 3 yr old vine (first year fruiting). It is the start of spring and the affected grape is a white seedless "Remaidy" grape. The disease seems to have spread from a neighbor's white seedless grape. Could someone please identify and possibly provide a treatment.
