Sooty canker, a wilt disease of branches and limbs, commonly attacks mulberry trees in the desert Southwest. This disease, caused by the fungus Hendersonula toruloides, infests many smooth-barked trees and occurs on a variety of plants. The fungus enters the plant mainly through wounds in sunburned bark, but also through cracks in the bark, pruning wounds, mechanical damage by equipment, frost damage and injuries from insects and other diseases. Sooty canker spreads from infected to healthy trees by spores carried by wind, rain, insects, birds, animals and pruning tools. Although infection is thought to occur during the winter, germination, growth and reproduction of the fungus occur best at high temperatures, 85oFoF. A mild, moist winter followed by a hot, dry summer stimulates development of this disease as does fluctuating irrigation, water-logged soils and damage to the tree by other diseases.

The fungi associated with this condition are saprophytic, that is, they do not feed on live plant tissue, but rather thrive on insect secretions with a high content of sugars. These secretions, known as honeydew, are particularly common with aphids, scales, white flies, and other insects. The insect honeydew provides nourishment for the fungus, and under proper conditions, the entire plant may be covered with the sooty mold. A black velvety coating made up of the fungal strands is formed on the surface of leaves, twigs and fruit. If the honeydew is light, it may appear only in spots.
