Study on Plasma Sterilization of Plant Anthracnose Pathogen in Water Mist

Abstract

In recent years, Miyazaki Prefecture located on the island of Kyushu in Japan promotes agricultural food industry. One of the activities is promotion of agricultural and livestock products. However, Miyazaki Prefecture is very far from large-scale consumption areas such as Tokyo and Osaka cities. To keep freshness of agricultural and livestock products during their transport is a serious problem from a viewing of putrefaction due to outbreak of blight. Apple Mango has been a very famous and representative product in Miyazaki Prefecture and it has successfully continued to make a good profit, however fruit rot disease such as plant anthracnose pathogen after harvest is serious. Therefore, a sterilization technique is strongly required. We here generated the dielectric barrier discharge plasma in water mist which might enable to sterilize the whole of target greengrocery because of its high diffusibility and carried out sterilization. Based on the results, fungicidal activity against Colletotrichum sp. was investigated.
