Pyhtium aphanidermatum has a wide host range, and is of economic concern to beets, peppers, chrysanthemum, cucurbits, cotton and turfgrasses, however, because P. aphanidermatum requires warmer temperatures, it is often seen in greenhouses and has a large impact in Poinsettia production. It is a major cause of root rot in papaya production in subtropical areas. While this is almost exclusively a plant pathogen, there is one documented case of P. aphanidermatum infecting a human being injured in the Afghanistan conflict.
