Sooty mold
Sooty mold (also spelled sooty mould) is a collective term for different Ascomycete fungi, which includes many genera, commonly Cladosporium and Alternaria. It grows on plants and their fruit, but also environmental objects, like fences, garden furniture, stones, and even cars. The mold benefits from either a sugary exudate produced by the plant or fruit, or honeydew-secreting insects or sap suckers the plant may be infested by.
Sooty mold itself does little if any harm to the plant. Treatment is indicated when the mold is combined with an insect infestation.
Sooty mold is a collective, self-descriptive term for a number of different fungi; it is a black, powdery coating adhering to plants and their fruit or environmental objects.
The ecology of the different species, their interactions, relationship to the host are little understood. A chance observation of a Microcyclospora tardicrescens inhibiting the growth of the fruit pathogen Colletotrichum fioriniae in dual culture tests, yielded trichothecolone acetate and its (S)-7-hydroxy derivative as active principles for the interaction between M. tardicrescens and C. fioriniae.
Common genera of sooty mold fungi found are Aethaloderma, Capnodium, Cladosporium, Euantennaria, Scorias, and Trichomerium.
Other genera causing sooty molds are Alternaria, Cladosporium, Aureobasidium, Antennariella, Limacinula, Scorias, Meliola, and Capnodium.[citation needed]
Sooty mold grows particularly well on plants that produce a sugary exudate, if they are infested by honeydew secreting insects such as aphids, scales and the whitefly, or when infested by insects that suck sap from the host plant.
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. Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit these trees. The honeydew can rain down on neighboring and understory plants. Occasionally citrus may exude sweet sticky secretions and sooty molds can grow on these.
