Applications

Mode of action Diclofop-methyl is a selective systemic herbicide, also with contact action, absorbed primarily by the leaves, with some absorption by the roots in moist soil. Undergoes rapid transformation to diclofop, which is translocated within the plant. Diclofop-methyl (R)-(+)- enantiomer shows significantly greater herbicidal activity by foliar application to 3 weed species than does the (S)-(-)- enantiomer, but there was less difference by soil application (H. J. Nestler & H. Bieringer, Z. Naturforsch. B. Anorg. Chem. Org. Chem., 1980, 35B, 366).  Uses For post-emergence control of wild oats, wild millets, and other annual gra
