Abstract
THE inability of the herbicide 4-chloro-2-methyl phenoxyacetic acid (MCPA) to control certain dicotyledonous weeds can be overcome by introducing into the molecule a single α-alkyl substituent1. DL-α-(4-chloro-2-methylphenoxy) propionic acid (CMPP) is now widely used to control Galium aparine (cleavers), an important cornland weed.
