Sooty mold

Symptoms and damage

Sooty mold is a thin, black layer of film found on the underside of fruit tree leaves, on the skin of fresh fruit,andonScheffleraarboricola leaves and also on many surfaces in and around the home. This mold grows rapidly following an insect`s attack on a plant, especially after the insect has fed on the leaves. When insects attack a plant, they often feed on the juice inside the leaves or fruit, extracting as many nutrients as they can in one sitting. What they can`t fully digest or utilize they excrete, often on the leaves or fruit of the plant.

When combined with the sugars of fruit-growing plants,avd  the leaves this excrement causes a chain reaction that fosters a breeding site for germs of all sorts. This is when mold quickly forms, causing damage to the affected plant and surrounding plant life. Sooty mold can slowly but surely crawl its way to neighboring plants, potentially destroying harvests. One should always inspect growing fruit trees, plants, or flower beds to see whether this black film has developed. Aphids and whiteflies are common insects that can cause this mold to develop.
