Sooty Mold on Citrus Leaves
August 17, 2018
Sooty mold can completely cover leaves of infected plants. It is made up of several types of fungal species and is a grey- to black-colored mold that grows on the honeydew residue produced by aphids, scale, and whiteflies.
To correct sooty mold, wipe plant leaves with soapy water, a plant wash product, or neem oil.
