Extract

The distribution of 3 (p–chlorophenyl)–1,1–dimethyl urea (CMU) in the soil horizon is an important factor to consider in using the material since it is a soil active herbicide. It has been reported that the persistence and toxicity of CMU vary considerably with soil type, temperature, and moisture conditions.
