Diclofop-methyl Chemical Properties,Uses,Production
Chemical Properties
A white crystalline solid. Odorless. Can also be commercially available as a clear to dark brown liquid with a typical solvent odor
Uses
Herbicide.
General Description
Colorless crystals. Decomposed by either strong acid or base. Used as a selective herbicide.
Air & Water Reactions
Slightly soluble in water (3 mg/l).
Reactivity Profile
A bridged diphenyl.
Hazard
Moderately toxic by ingestion and skin contact. Low toxicity by inhalation.
Agricultural Uses
Herbicide: Some uses are classified as U.S. Restricted Use Pesticide (RUP). Diclofop-methyl is a selective post-emergence herbicide used to control wild oats and annual grassy weeds in grain and vegetable crops: alfalfa, carrots, celery, box, field and french beans, barley, wheat, brassicas, parsnips, peas, potatoes, rapeseed (canola), soy beans, oilseed rape, onions, sugar beets and lettuce.

Potential Exposure
Diclofop-methyl is a chlorophenoxy; aryloxyphenoxypropionate acid selective postemergenceherbicide used to control wild oats and annual grassy weeds in grain and vegetable crops: alfalfa, carrots, celery, box, field and French beans, barley, wheat, brassicas, parsnips, peas, potatoes, rapeseed (canola), soy beans, oilseed rape, onions, sugar beets and lettuce. Some uses are classified RUP
Environmental Fate
Biological. From the first-order biotic and abiotic rate constants of diclofop-methyl in estuarine water and sediment/water systems, the estimated biodegradation half-lives were 0.24–12.4 and 0.11–2.2 days, respectively (Walker et al., 1988).
Metabolic pathway
Two resistant biotypes of black-grass (Peldon A1 and Lincs. E1 of Alopecurus myosuroides) exhibit moderately enhanced metabolism of 14C-diclofop methyl. Diclofop methyl is hydrolyzed to the corresponding propionic acid which undergoes further degradation to give polar metabolites. The amounts of the metabolites depend on the metabolism activity of the individual biotypes. In wheat, three isomeric hydroxylated metabolites are identified in a major metabolic pathway after acid hydrolysis of the glucoside conjugates.
