Disease resistance avoids having to spray.

Luckily there is a very good spray for mildew on vines that, applied thoroughly to all leaves, will give complete and lasting control in a single application. 

‘Black Hamburgh’ is one of the easiest varieties to grow.

If you spray with a rose spray that contains myclobutanil, you will get control. This is used on fruit well in advance of harvest, on grapes, ideally in spring when the mildew is just starting to spread to the new foliage.
