DICLOFOP-METHYL


TRADE OR OTHER NAMES: The active ingredient diclofop-methyl is found in a variety of commercial herbicides. Trade names for products containing diclofop-methyl include Hoelon, Illoxan, Hoe-Grass,and One Shot (diclofop plus bromoxynil plus MCPA) (1, 300).

REGULATORY STATUS: Some or all uses of diclofop-methyl may be classified as a restricted use pesticide (RUP). Check with specific state regulations for local restrictions which may apply. Restricted products containing diclofop-methyl must carry the Signal Word "Danger" on their label; others may carry the Signal Word "Caution" (58).

CHEMICAL CLASS: diphenylether/chlorophenoxy herbicide

INTRODUCTION: Diclofop-methyl is a selective post-emergence herbicide for control of wild oats and annual grassy weeds found among brassicas, carrots, celery, field beans, french beans, broad beans, barley, wheat, parsnips, peas, potatoes, soy beans, oilseed rape, onions, sugar beet, and lettuce (1).

The herbicide comes in emulsifiable concentrate formulations (1, 242). It is compatible with herbicides derived from urea, i.e. asulam, ioxynil, etc., although mixing with dinoseb and growth-regulating herbicides leads to decreased effectiveness (1).
