Suppression effects of reactive species generated in atmospheric pressure air plasma on strawberry pathogen is investigated. Suppression effects, dose of hydroxyl radical and O₃ are measured by varying air flow rate in the range of 4-16 L/min. At 4 L/min, despite the lowest dose of hydroxyl radical and O₃, significant suppression effect on strawberry pathogen is observed. It seems that there is other factor of suppression effects apart from those reactive species.
