Diclofop-methyl undergoes hydrolysis to form diclofop-acid a compound that also exhibits herbicidal properties. Diclofop-methyl was registered in Canada in 1977 and is sold under the tradename Hoe-Grass. Diclofop-methyl is used for postemergence control of wild oats, wild millets, and other annual grass weeds in wheat, barley, rye, red fescue, and broad-leaved crops such as soya beans, sugar beet, flax, legumes, potatoes, and cucumbers. Diclofop-methyl is a selective systemic herbicide that is used primarily in the prairies. It destroys the cell membrane, prevents the translocation of assimilates to the roots, reduces the chlorophyll content, and inhibits photosynthesis and meristem activity."}]
