I have a grape vine and the grapes are showing what I see as Black Rot, the vine is over 10 years old and this is the first time I have seen this. Can anyone suggest what I can do now in order to remove the rot for next year pleae

    We have vines in a greenhouse for some decades. 3 years ago they suffered with powdery mildew. We tried organic control but didn't work. So the following year we had to use a fungicide that was sprayed on the vines before they produced flower clusters. Had a small harvest. This year we did the same and the harvest has been brilliant. I know this isn't the same as black rot but clearing up all the foliage is essential and the using a fungicide before the flowers come out next year should help.
