Controlling plant-sipping insects and their ant bodyguards, hosing with mild soap and warm water, and pruning are ways to rid citrus tree leaves of black powder. Sooty mold, the black powder in question, establishes where garden pests such as aphids, leafhoppers, mealybugs, psyllids, soft scales and whiteflies excrete the excess nutrients, as honeydew, from internal plant fluids onto leaf surfaces, where the sooty mold fungus thereby is encouraged to grow.
Applying horticultural or neem oils against eggs and insecticidal soap against other stages, keeping the structure of the citrus tree in question open to air and sun, preventing tree limbs from coming into contact with structures that ants can use as walkways, and putting anti-ant sticky compounds at the bases of trees will solve the problem of ants that protect honeydew-makers, the fungi that grows on honeydew, and the plant-sippers that make honeydew.
