Abstract

The anti-biotic effect of slightly acidic electrolyzed water on plant pathogen was determined. The spores of 4 kinds of fungal pathogen and 17 kinds of plant pathogenic bacteria were applied at different concentration.Slightly acidic electrolyzed water showed strong growth inhibition in germination of fungi spores tested. In addition, by the treatment with slightly acidic electrolyzed water for 30 sec., all kinds of bacteria tested were inhibited to grow on the medium.The anti-biotic effect observed in this study was considered to be caused by hypochlorous acid (HClO) in the slightly acidic electrolyzed water, which has been pointed out in the inhibition mechanism in case of human pathogen applied with slightly acidic electrolyzed water.Because the anti-biotic effect of slightly acidic electrolyzed water was not persistent and residual, slightly acidic electrolyzed water may not be effective to control the disease after severely occurred. Slightly acidic electrolyzed water may be useful in the field to control the population of plant pathogen surrounding the plants or to prevent the pathogen invading before the disease occurred.
