Sooty Mold of Pears in the Home Fruit Planting

The fungi live on honeydew excreted by insects such as aphids, psylla, and whiteflies. When only a few insects are present on host plants excreting only a small amount of honeydew, sooty mold appears in spots. When insect secretions are abundant, the surfaces of leaves and fruit might have a near-continuous coating of the black, tissue-paper-thin, sooty mold.

Disease Management

Control is directed against the insects producing the honeydew. These insects need to be identified before appropriate controls can be undertaken.
