Blister mite in grapevine

Question

I have blister mite on my grapevine and almost all the leaves are affected. I have a few small bags of flowers of sulphur. Shall I feed the vine with that? I believe the standard treatment is to spray with sulphur in late winter. I don’t really want to do that, as have no sprayer. Would flowers of sulphur do anything at all…either good or bad?

Thanks

It is not really necessary to treat Blister Mites in home gardens.
Here is a link with more information.

Flowers of sulphur is used in some cases to prevent the fungi and bacteria that cause root rot.
I cannot find any research that relates it's use to the Blister Mite.
