Grape Disease Identification #880705

Asked August 08, 2024, 1:09 PM EDT

I have a Glenora grape I planted this year which is growing well but leaves are showing some sort of disease. The leaves have small white dots on the bottom of the leaves and raised bumps on the top. I’d like to identify this disease and understand if it’s problematic and how to treat it or if I should remove the grape plant.

Not a disease but a mite called the grape Erineum mite. Here is some more information on this organism: https://pnwhandbooks.org/insect/small-fruit/grape/grape-grape-erineum-mite
