title: Action Spectrum of the Activity of Acifluorfen-methyl, a Diphenyl Ether Herbicide, in Chlamydomonas eugametos.
abstract: Light is required for the herbicide activity of diphenyl ether herbicides. An action spectrum of acifluorfen-methyl activity with Chlamydomonas eugametos (Moewus) determined that cell death occurred at two peaks of light; 450 and 670 nanometers. These data indicate both chlorophyll and carotenoids, but not riboflavin, are involved in herbicide toxicity.
