Sooty moulds grow in thin black layers on leaves on which aphids, witefly or other sap-sucking insects have deposited their honeydew. It does not grow parasitically but it harms plants indirectly and is also unsightly. The mould coats the leaves and this blocks out light and makes photosynthesis less effective. Plant growth can be reduced ...
Sooty mold is commonly seen on the leaves of ornamental plants such as azaleas, gardenias, camellias, crepe myrtles, Mangifera and laurels. Karuka is affected by sooty mold caused by Meliola juttingii. [6] Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit ...

Deposits of sooty mold caused by the fungus Scorias spongiosa build up below the colonies, growing on the copious amounts of honeydew the insects exude. [3] Multiple ant species are attracted, gleaning honeydew beneath aphid feeding areas at beech trees and tending aphids at the cypress tree sites. [1]
