Abstract

The morphological symptoms of 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) and 3-(p-chlorophenyl)-1,1-dimethylurea (monuron) toxicity were expressed in the light but not in the dark. Various wavelengths of narrow band light were produced by the use of colored plastic filters. Oats, var Kanota, and red kidney beans were used. The degree of injury was a function of light intensity, the higher the light intensity the greater the injury. The action spectrum indicated that chlorophyll was the principal absorbing pigment involved in this injury.
