51338-27-3 Usage
Description
Diclofop-methyl, a colorless crystalline solid that is odorless and can also be commercially available as a clear to dark brown liquid with a typical solvent odor, is a selective post-emergence herbicide. It is decomposed by either strong acid or base and is used to control wild oats and annual grassy weeds in various grain and vegetable crops.
Uses
Used in Agriculture:
Diclofop-methyl is used as a selective herbicide for controlling wild oats and annual grassy weeds in a variety of crops. This application is particularly important for maintaining crop health and yield.
Used in Grain Crops:
Diclofop-methyl is used as a herbicide for controlling weeds in grain crops such as barley, wheat, and rapeseed (canola). Its selective nature ensures that the target weeds are eliminated without causing significant harm to the desired crop.
Used in Vegetable Crops:
Diclofop-methyl is also used as a herbicide in vegetable crops, including carrots, celery, box, field and french beans, brassicas, parsnips, peas, potatoes, onions, sugar beets, and lettuce. This helps to improve the quality and yield of these crops by reducing competition from weeds.
Used in U.S. Restricted Use Pesticide (RUP):
Some uses of Diclofop-methyl are classified as U.S. Restricted Use Pesticide (RUP), indicating that its application requires specific knowledge and adherence to safety guidelines to minimize potential risks to human health and the environment.
Air & Water Reactions
Slightly soluble in water (3 mg/l).
Reactivity Profile
A bridged diphenyl.

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.

pesticides and pesticide containers. Containers must be disposed of properly by following package label directions or
by contacting your local or federal environmental control
agency, or by contacting your regional EPA office
Check Digit Verification of cas no
The CAS Registry Mumber 51338-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,3,3 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51338-27:
(7*5)+(6*1)+(5*3)+(4*3)+(3*8)+(2*2)+(1*7)=103
103 % 10 = 3
So 51338-27-3 is a valid CAS Registry Number.
