Superficial gray to black blotches form on green stems and twigs, giving them a sooty appearance. Disease cycle. The causal organism is com-mon in the environment and grows below the cuticle on plant surfaces. It does not appear to harm. Sooty mold is caused by saprophytic fungi. It is not a disease and does not infect living plant tissue. Heavy growth by the fungus can reduce photosynthesis but does not harm the plant in any other way. Sooty mold may also grow on sap or resin associated with wounds The only effective treatment against sooty mold is to first treat the insects that are the cause of it.

Sooty mold fungus can grow wherever the honeydew drips- on sidewalks, lawn furniture, or anything. In almost all cases, the 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 This is a condition call sooty mold (aka black head mold) (Figure 1).

This mold can be scraped off with a fingernail to reveal a healthy green leaf below As the fruits matured and stems grew, the mildew stain gradually covered the peels and stems to form sooty mold. The causal pathogen was isolated and identified as Cladosporium tenuissimum based on morphological characteristics, molecular data (sequence analysis of fragments of internal transcribed spacer (ITS), partial translation elongation. Black mold is primarily a postharvest condition. It occurs on both onions and garlic, but is more of a concern in onion crops. Black mold occurs most commonly where onions or garlic are grown under warm conditions, such as the desert areas of California.
