• 説明

  Linuron is found as white crystals that have no smell. It is very slightly soluble in water. Linuron can enter the body either by ingestion of contaminated food or water or by dermal contact. Linuron can cause nausea, vomiting, and diarrhea. Eye contact can cause irritation. There is little evidence available as to the effects of exposure to linuron on human health. However, exposure to linuron at normal background levels is unlikely to have any adverse effect on human health.

• 化学的特性

  White crystalline solid or powder. Odorless. Commercial product may be available a water soluble or emulsifiable concentrate.

• 使用

  Linuron is used to control annual and perennial broadleaf and grassy weeds on crop and noncrop sites. It is used as a pre- and post-emergent herbicide. It works by inhibiting photosynthesis in target weed plants. It is used in soybean, cotton, potato, corn, bean, pea, winter wheat, asparagus, carrot, and fruit crops. It is also used on crops stored in warehouses and storerooms. Linuron is classified by the US Environmental Protection Agency (EPA) as a Restricted Use Pesticide (RUP).

• 定義

• 农业用途

  Herbicide: Inhibits photosynthesis. Linuron is a selective, pre-emergence herbicide used to control grasses and broadleaf weeds in carrots, beans, peas, asparagus, maize, potatoes, soybeans, sorghum, wheat, bananas, coffee, cotton and ornamentals. It is also used for control of annual weeds in storehouses, roadsides, fence rows and other noncrop lands. Linuron is frequently used in formulations with other herbicides, insecticides and fungicides.

• 環境運命予測

  Soil. Linuron degraded in soil forming the common metabolite 3,4-dichloroaniline (Duke et al., 1991). In an aerobic, biologically active, organic-rich, pond sediment, linuron was converted to the intermediate 3-(3-chlorophenyl)-1-methoxymethylurea. This compound further degraded to unidentified compounds (Stepp et al., 1985).
  Linuron was degraded by Bacillus sphaericus in soil forming N,O-dimethylhydroxylamine and carbon dioxide (Engelhardt et al., 1972). Only 1 ppm 3,4-dichloroaniline was identified in soils after incubation of soils containing 500 ppm linuron (Belasco and Pe
  The half-lives for linuron in soil incubated in the laboratory under aerobic conditions ranged from 56 to 88 days with an average of 75 days (Moyer et al., 1972; Hance, 1974; Usorol and Hance, 1974). In field soils, the average half-life for linuron was 8
  Plant. Undergoes demethylation and demethoxylation in plants (Hartley and Kidd, 1987). Metabolites identified in carrots 117 days after treatment were 3,4-dichlorophenylurea, 3-(3,4-dichlorophenyl)-1-methylurea and 3,4-dichloroaniline. About 87% of the linuron remained unreacted (Loekke, 1974).
  Photolytic. When an aqueous solution of linuron was exposed to summer sunlight for 2 months, 3-(3-chloro-4-hydroxyphenyl)-1-methoxy-1-methylurea, 3,4-dichlorophenylurea and 3-(3,4-dichlorophenyl)-1-methylurea formed at yields of 13, 10 and 2%, re

• 代謝経路

  The main photoproducts initially formed in the phototransformation of linuron and chlorbromuron in aqueous solution result from photolysis, i.e. hydroxylation with release of the halide ion, and from elimination of a methoxy group. The orientation of the reaction depends on the wavelength: short wavelengths (254 nm) favor demethoxylation and photolysis in the meta position,whereas, with black light longer than 330 nm, photolysis in the para position is the main reaction observed. In soils, 4-bromo-3-chloroaniline is identified as a soil degradation product of chlorbromuron.

• 不和合性

  Amides are incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Similar organic amides react with azo and diazo compounds, releasing toxic gases. Contact with reducing agents can release flammable gases. Amides are very weak bases but they can react as acids, forming salts. Mixing amides with dehydrating agents such as such as phosphorus pentoxide or thionyl chloride generates the corresponding nitrile
