The antifungal effect of postharvest treatment of Artemisia capillaris Thunb. extract on diseases that cause fruit rot in peaches after harvesting was examined. It is known the A. capillaris extract has a potent antifungal effect, and the principal ingredient of this extract is capillin. First, the antifungal effects of purified capillin on Monilinia fructicola, Phomopsis sp., Rhizopus sp., Gloeosporium sp. were investigated. As a result, extremely high antifungal effect on M. fructicola was observed, and the MIC (minimal inhibitory concentration) value was 0.25-0.5 ppm. However, relatively low antifungal effects on other fungi were observed, with MIC values ranging from 2-4 ppm. When peach fruit treated or untreated with A. capillaris extract were inoculated with M. fructicola, which causes brown rot disease, the diseased areas in treated fruits were smaller than those in untreated fruits. The effects of treatment on the quality of peach fruit were also investigated. The fruit quality was almost equal between fruit treated with A. capillaris extract and those that had not been treated.
