A confusing array of symptoms, none of which fit a particular problem, so some questions for you. When it turns black, can you check the trunk, stems and backs of leaves and young buds for any signs of infestation by some sort of insect, or scale insect. Second, what colour are the caterpillars 'all over the tree' and when do you normally see these? Third, do these caterpillars damage the fruits in any way, and if so, how?
