Water that expresses pathogen-resistance genes (pr gene clusters) to encode plant immunoproteins, a method of preventing plant diseases using the water, and a device for producing the water

An active oxygen containing water producing apparatus, for use in a method of preventing diseases in plants, the apparatus comprising:

• an ultraviolet-ray light source which is arranged in a vessel provided with a water supply port and an active oxygen containing water takeout port;
• and
• a photocatalytic body which is formed of a fibrous body and surrounds a periphery of the ultraviolet-ray light source with a predetermined gap held between the photocatalytic body and the ultraviolet-ray light source, wherein
• a water flow supplied to the inside of the vessels is formed of a first water flow which ascends and descends by passing the gap defined between the ultraviolet-ray light source and the photocatalytic body, a second water flow which ascends and descends by spirally passing on an outer periphery of the photocatalytic body, and a third water flow which flows into or flows out from the texture of the photocatalytic body.

An active oxygen containing water producing apparatus, for use in a method of preventing diseases in plants, the apparatus comprising:

• a vessel which is made of a material which allows the transmission of ultraviolet rays therethrough, is provided with a water supply port and a water discharge port and houses a catalytic body in the inside thereof;
• an ultrasonic irradiation part which irradiates ultrasonic waves in the flow direction of water which flows into the inside of the vessel from the water supply port;
• and
• an ultraviolet-ray irradiation part which is arranged on the periphery of the vessel and irradiates ultraviolet rays to the catalytic body from the outside of the vessel, wherein
• at least a portion of the catalytic body is arranged in an area where an irradiation area to which ultrasonic waves are irradiated from the ultrasonic irradiation part and an irradiation area to which ultraviolet rays are irradiated from the ultraviolet-ray irradiation part overlap with each other.
