White powder on Vines of Grapes #937817

Asked July 03, 2026, 9:14 AM EDT

I just noticed the vines of my frontinac grapes have a white powder on them. I don't like using chemicals if possible so if there is a non chemical to use to remove this that would be great. In 13 years at ths houses, this has never happened.
