Metolachlor is an amide-based selective phytoplankton herbicide . The medicament is absorbed by the weeds of the weeds, wherein the monocotyledonous weeds are mainly absorbed by the coleoptile, and the dicotyledonous weeds are absorbed by the hypocotyls and the young roots, and are absorbed and absorbed upwards, and the protein of the germinating seeds is synthesized, thereby inhibiting the shoots and roots. The growth is that sensitive weeds die before they are germinated or just unearthed.
