Abstract

Exposures of trifluralin, α. α, α-trifluoro-2,6-dinitro-N, N-dipropyl-p-toluidine, coated on glass and soil surfaces were made to sunlight and to artificial light from a mercury-vapor source having a wavelength range of 300–700 millimicrons. Ultraviolet absorption spectra of irradiated samples exhibited progressive change with time and intensity of exposure. Exposures on a glass surface to sunlight for four to six hours resulted in a decrease in the plant growth inhibitory activity of trifluralin. Exposures on soil surtaces also indicated that photodegradation occurs, but at a much reduced rate.
