The fungus is usually dark colored and powdery-like, hence the name sooty mold. The fungi associated with this condition are saprophytic, that is, they do not feed on live.

When sooty molds are present on any surface in the landscape, it indicates there is, or has been, a sucking insect population present in the vicinity.

At high levels, mealybugs can cause plants to defoliate and even cause plant death. How to Identify Mealybugs. Sooty molds can be indirectly controlled by reducing populations of sucking insects that excrete honeydew.

Use the appropriate recommended chemicals that control aphids and other sucking insects. The appropriate chemicals your trees need for these sucking insects might be applying horticultural oil during the dormant season followed by an insect growth regulator in the mid-summer.

Aside from being unsightly the sooty mould can block sunlight to leaves and reduce plant vigour in severe cases. To get rid of the sooty mould you need to address the pest problem. Once you have that under control and they are no longer producing the honeydew, the sooty mould will dry up and flake off.
