| Abstract
| - Natural perylenequinonoid pigments (PQPs) have long been known as excellent photosensitizers.Here it is reported that PQPs, when dispersed into a micellar system, are unexpectedly very effectivein inhibiting the growth of various fungi in the dark and that light can enhance the activity further. Inboth cases, reactive oxygen species (ROS) play a crucial role. The unique ROS-based antifungalmechanism and the excellent physicochemical properties of PQPs promise the advent of a newgeneration of wide-spectrum agrofungicides. Keywords: Antifungal agents; reactive oxygen species; photosensitizer; perylenequinonoid pigments
