Thanks to many insect pests, such as aphids and scale insects, black sooty mold is likely the most common blight of bamboo plants. Insects generously create the perfect conditions for mold to grow when they feed on the bamboo plant and leave behind a sticky honeydew substance.

    Black sooty mold is actually an airborne fungi spore that latches on to the sweet sticky honeydew secreted by leaf and bark feeding insects. On Crepe Myrtles and most other plants the culprit here is either sap sucking Aphids or Bark sucking Scale.   “Black mold” refers to several species of mold (which is a type of fungus) that have a dark green or black appearance. One such type is Stachybotrys chartarum.. The color of a mold isn’t.

The pathogens are dark fungi growing either on the "honeydew" excreted by sucking insects or on exuded sap material coming from leaves of certain trees. These sucking insects can include aphids and scale insects and sooty mold may occur on any tree but is most commonly seen on boxelder, elm, linden, and especially maple trees.
