Diuron (330-54-1) is used as an herbicide for weed control on noncrop lands and agricultural crops such as asparagus, pineapple, cotton, and sugarcane. It is also used as a sterilant in soil, a mildewcide in paints and stains, and an algicide in fish production.??? ??
White, odorless crystalline solid??
Diuron is a urea compound used as a preemergence herbicide in soils to control germinating broad-leaved grasses and weeds in crops such as apples, cotton, grapes, pears, pineapple and alfalfa; sugar cane ?owering depressant.??
ChEBI: Diuron is a member of the class of 3-(3,4-substituted-phenyl)-1,1-dimethylureas that is urea in which both of the hydrogens attached to one nitrogen are substituted by methyl groups, and one of the hydrogens attached to the other nitrogen is substituted by a 3,4-dichlorophenyl group. It has a role as a herbicide, a photosystem-II inhibitor, a xenobiotic, an environmental contaminant and a mitochondrial respiratory-chain inhibitor. It is a dichlorobenzene and a 3-(3,4-substituted-phenyl)-1,1-dimethylurea.?? ??
Diuron is a white crystalline solid/wettable powder and used as a herbicide. Diuron is registered for pre- and post-emergent herbicide treatment of both crop and non-crop areas, as a mildewcide and preservative in paints and stains, and as an algaecide. Diuron is a substituted urea herbicide for the control of a wide variety of annual and perennial broad-leaved and grassy weeds on both crop and non-crop sites.Thus, the application of diuron is wide for vegetation control and weed control in citrus orchards and alfalfa fields. The mechanism of herbicidal action is the inhibition of photosynthesis. Diuron was first registered in 1967. Products containing diuron are intended for both occupational and residential uses. Occupational uses include agricultural food and non-food crops; ornamental trees, flowers, and shrubs; paints and coatings; ornamental fish ponds and catfish production; and rights-of-way and industrial sites. Residential uses include ponds, aquariums, and paints.

Diuron is incompatible with the following: Strong acids .????
INHALATION: May cause irritation of nose and throat. EYES: Irritation. SKIN: Moderately irritating to skin.???
Herbicide: Diuron is a substituted urea herbicide used to control a wide variety of annual and perennial broadleaf and grassy weeds, as well as mosses. It is used on non-crop areas and many agricultural crops such as fruit, cotton, sugar cane, alfalfa, and wheat. Diuron works by inhibiting photosynthesis. It may be found in formulations as wettable powders and suspension concentrates.???
