Title: HOW to Recognize and Control Sooty Molds

Author: Kessler, Kenneth J. Jr.;

Date: 1992

Publication Series: How-To Leaflets (HT)

Description: Sooty molds are dark fungi that grow on honeydew excreted by sucking insects or on exudates from leaves of certain plants. Typically, sooty mold growths are composed of fungal complexes made up of ascomycetes and fungi imperfecti. Some of the common genera of fungi found in sooty mold complexes are Cladosporium, Aureobasidium, Antennariella, Limacinula, Scorias, and Capnodium. The dark color of sooty mold growth is due to the presence of melanoid pigments in the cell walls of the hyphae that make up the sooty mold colonies (fig. 1). Many sooty mold fungi have mucilaginous cell walls that help them adhere to the surfaces on which they grow and also serve to prolong periods of wetness by absorbing moisture for their growth.
