This article tells which fungicides to use for black rot - captan and myclobutanil. Just look for a fungicide with either of those ingredients. We don't make brand recommendations.


Powdery mildew is best prevented with air circulation via trimming plants and locating the vines in full sun. Use a fungicide labeled for powdery mildew on edibles.
