Sooty mold is a collective term for different Ascomycete fungi, It grows on leaves, shoots of tea. The mold benefits from either a sugary exudate produced by the plant or fruit, or if the plant is infested by honeydew-secreting insects or sap suckers. Sooty mold itself does little if any harm to the plant but may influence efficiency of photosynthesis.
