Sooty Mold is a form of fungus that grows on the sugary honeydew secreted by aphids, scales, the whitefly, and other insects that suck the sap from plants. Sooty Mold is an unsightly black powder that can quickly coat the leaves of a plant in just a few weeks. The fungus itself doesn’t really harm the plant; it just ruins the plant’s appearance. Sooty Mold can be prevented by getting rid of the insects that secret the honeydew that attracts the Sooty Mold.
