Abstract

The metabolic fate of root-applied, carbonyl-labeled, 14C-3-(3-chloro-4-bromophenyl)-1-methoxy-1-methylurea (hereinafter referred to as chlorbromuron) was investigated in tolerant corn (Zea mays L., var. N.J. 9) and susceptible cucumber (Cucurbita sativus L., var. Marketer) in a time-course study. The major metabolite found in corn shoots and roots was the nonphytotoxic 3-(3-chloro-4-bromophenyl)-1-methoxyurea. Evidence of “binding” was found in both shoots and roots of corn. No evidence was found for the metabolism of chlorbromuron in cucumber; however, some binding occurred in both shoots and roots.
