Extract

Interest in the substituted urea compounds for their herbicidal properties was precipitated by Bucha and Todd's (3) report that 3–(p–chlorophenyl)–1,1–dimethylurea (monuron) was extremely phytotoxic. Freed (6) reported that only asymmetrically substituted ureas are effective as herbicides. Substitution on the para position was reported to result in greatest activity followed by meta. An ortho substitution reduced activity to half or less than that of the comparable para substitution.
