— An action spectrum for conidial (spore) production in the fungus Stemphylium solani Weber is presented. The response is in the far‐ultraviolet region (far u.v.). The spectrum shows a single peak at 280 nm, a shoulder at 260 nm, a trough at 250 nm, followed by a rise which is still rising at 230 nm, the shortest wavelength studied. The u.v. induced spore stimulation can be interrupted temporarily by irradiation in the visible region within 4 hr after induction.
