摘要:
A lighting apparatus for controlling a plant disease is provided to reliably inhibit a spore formation and a hyphal growth of a filamentous fungi, reliably induce a disease resistance, prevent a leaf scorch, and promote a growth of a plant. A UV light source repeats a light irradiation which has an irradiation pattern of combining a light irradiation, in which UV-C and UV-B and a visible light are superimposed, with a visible light irradiation alone at least twice a day. The emission of UV-B and UV-C enables the reliable inhibition of the spore formation of the filamentous fungi, for example. Its intermittent emission prevents a plant from getting too used to ultraviolet rays, promotes a generation of an antibacterial substance, for example, and prevents a leaf scorch. The continuous emission of the visible light enables a promotion of a growth of the plant.
