Quick Fixes
Immediate physical removal
Use a strong water stream to remove as much sooty mold as possible. Do this in the morning so leaves dry during the day.
Apply insecticidal soap
Spray insecticidal soap directly on pests (aphids, scale). Cover all leaf surfaces including undersides.
Chemical pest control
Use fast-acting insecticide (pyrethroids or organophosphates) if infestation is severe. Strictly follow manufacturer's instructions.
Second application
After 5-7 days, repeat insecticide application to eliminate newly hatched pests.
Final cleaning
Once pests are controlled, wash leaves again with water and soap to remove sooty mold and honeydew residue.
Organic Treatment

Inspect the plant to find aphids, scale insects, or whiteflies. Sooty mold will disappear after eliminating these insects.
Wash off sooty mold
Mix 1 tablespoon of mild soap in 1 gallon of lukewarm water. Use a soft cloth to gently wipe affected leaves.
