Conidium germination suppression effect of reactive species in air plasma effluent is experimentally investigated. Reactive species generated in plasma has been controlled by gas flow rate. It is found that conidium germination is significantly suppressed with 30 seconds plasma exposure. Also, it is inferred that germination suppression would result from either long-life-time species or short-life-time species.
