That is most likely sooty mold which grows on the sugary exudates from scale, mealybugs, whiteflies or aphids. If you can identify the pest then a proper remedy can be prescribed. Otherwise you might try a neem oil product. Thorough coverage is critical and a few repeat applications a couple of weeks apart will be needed to get better control.

Thanks for the question. Please stop in again soon!
