Help! Our vine has a good crop of grapes developing, suddenly there is a thick white mould growing on the fruit, and brown patches on some leaves. Anyone know what it is and what to do about it!

This is mildew,powdery and downy probably .You might be able to get it under control with BRAVO .Use a fine spray ,under and over the leaves to get good coverage . Read the label and follow the instructions on dilution and frequency .(7-10 days) Wear a Carbon filled fabric mask ,and goggles .

Do you thin your grape as it grows.This may help in future years as it allows air movement and sun through the plant keeping it dry so there is less likelyhood of mildew. Once you have mildew it is hard to get rid of. Prune foliage back to two leaves above last bunch of fruit. I do this and never get mildew but my variety maybe more resistant, don't know.

Is it in a Northern position! It should be, trim it so it's opened up more and not a thick tangle, that helps too.
