This contribution only demonstrates the disinfection of F. solani in water by H2O2 and sunlight, however, we think that it could also be a novel photo-promoted treatment against fungal skin infection. Photodynamic treatment (PDT) is an emerging therapeutic procedure based on the use of photosensitizers, compounds that generate ROS on irradiation with visible light (usually photoactive dyes). PDT has been shown to be effective against skin cancer and fungal skin diseases ( Calzavara-Pinton et al., 2005). The synergic effect of H2O2 and sunlight could inactivate fungal skin pathogens without risking degradation products from dyes. Secondly, as F. solani is a common pathogen causing eye diseases from the use of contaminated contact lenses ( Zhang et al., 2007), combined H2O2 and near-UV light for lens disinfection is another possible application. And thirdly, improved seed disinfection in the presence of H2O2 and sunlight is possible, as fungi on the surface of seeds are often passed to the soil
