What is Sooty Mould?
Sooty mould is a type of fungus which covers plant leaves, stems and twigs in a black sticky
substance. In almost all cases, sooty mould is secondary to an infestation of insects that secrete honeydew. These
insects include aphids, scale, mealybugs and white flies. Treating the insects will remove the source of the honeydew
and dry up the sooty mould, which will eventually fall or wash off the foliage. The mould itself does not feed on the
plant, however as it covers the leaf surface, it blocks sunlight and reduces photosynthesis, which is essential for plant
What are the symptoms?
Black sooty growth covering any part of the leaf, stem or branch of plants.
Control sap sucking insects which are the source of honeydew.
