I frequently have disease problems with other black tomatoes and it is mainly Gray Mold; but they still get all the other diseases of tomatoes also. I start early using the bleach spray on black tomatoes and make sure to keep them pruned to allow very good air flow and no leaves near the ground. They also need spraying with a good copper fungicide. If you do these things and it doesn't rain too much most of the black tomatoes will be very successful. If you are in the never prune camp or the totally organic camp you may be in for a rough time with black tomatoes if you live in an area where gray mold is a problem.
