Abstract

Radioactive sodium salt of 2,2–dichloropropionic acid (dalapon) was applied to the leaves or to the roots of sugar beets, a species tolerant of the herbicide, and yellow foxtail (Setaria glauca), a susceptible species. Autoradiographs indicated that dalapon entered through the leaves and roots, and moved throughout all portions of both species within 48 hours. Accumulation of dalapon was greatest in the younger tissues of both species. Paper chromatographic separations of aqueous extracts of the plants indicated no metabolic derivatives of dalapon in either species.
