メチルカルバミド酸3,5-ジメチル-4-メチルチオフェニル 化学特性,用途語,生産方法

• 農薬用途

  殺虫剤

• 説明

  Methiocarb was originally developed by Bayer as an insecticide. The bird-repellent properties of the compound were quickly recognized, however, and a number of applications for bird damage management followed (42).
  Methiocarb is a secondary repellent, and repellency occurs through aversive conditioning, by which birds that feed on treated food become sick and associate either the food or characteristics of the food with the discomfort (21). As a result, affected birds learn to avoid that food item. Often the avoidance response is locationdependent. For example, common ravens (Corvus corax) that learn not to eat eggs at one site will still feed on eggs at a different location (43).

• 化学的特性

  Methiocarb is a colorless crystalline powder.

• 使用

  Insecticide; molluscicide; bird repellent.

• 定義

  ChEBI: A carbamate ester obtained by the formal condensation of the phenolic group of 3,5-dimethyl-4-(methylsulfanyl)phenol with the carboxy group of methylcarbamic acid.

• 一般的な説明

  White crystalline powder with a mild odor. Used as an insecticide and immobilizing agent for birds, acaricide and molluscicide.

• 反応プロフィール

  Mercaptodimethur is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

• 健康ハザード

  As a carbamate insecticide, Mercaptodimethur is a reversible cholinesterase inhibitor and acts on the nervous system. It is classified as very toxic, and the probable oral lethal dose for humans is 50-500 mg/kg or between 1 teaspoon and 1 ounce for a 150 lb. adult.

• 火災危険

  When heated to decomposition, Mercaptodimethur emits very toxic fumes of nitrogen and sulfur oxides.

• 农业用途

  Acaricide, Molluscicide, Insecticide: Used to control slugs and snails, soil insects and spider mites in pome fruit, stone fruit, hops, strawberries, potatoes, beets, maize, vegetables and ornamentals. Also used as seed treatment to control fruit flies on maize and bird repellant on berries and cherries. Methiocarb producers deleted all food uses from their product labels between 1989-92. It is A U.S. EPA restricted Use Pesticide (RUP) except for residential application.

• 接触アレルゲン

  Methiocarb is an insecticide or molluscicide with a cholinesterase inhibiting effect. A case of contact dermatitis was reported in a carnation grower.

• 薬理学

  Methiocarb is a carbamate, and its mode of action is via the inhibition of acetylcholinesterase at synapses in the nervous system. Unlike many cholinesterase-inhibiting compounds, however, the effects of methiocarb are rapidly reversible, and the animal experiences only transitory disruption.

• 安全性プロファイル

  Poison by ingestion, skin contact, and intraperitoneal routes. Used as an insecticide, molluscicide, and bird repellent. When heated to decomposition it emits very toxic fumes of NOx and SOx. See also ESTERS and CARBAMATES.

• 職業ばく露

  A potential danger to those involved in the manufacture, formulation, and application of this nonsystemic acaricide and insecticide.

• 環境運命予測

  Soil. Methiocarb was oxidized, probably by singlet oxygen, to the corresponding sulfoxide and trace amounts (<5% yield) of sulfone when sorbed on soil and exposed to sunlight. The photosensitized oxidation was faster in soils containing the lowest organic carbon content (Gohre and Miller, 1986).
  Plant. On and/or in bean plants, the methylthio group is rapidly oxidized to the sulfoxide and sulfone (Abdel-Wahab et al., 1966) followed by hydrolysis yielding the corresponding thiophenol, methylsulfoxide phenol and methylsulphonyl phenol (Har
  Photolytic. When methiocarb in ethanol was irradiated by UV light, only a few unidentified cholinesterase inhibitors were formed (Crosby et al., 1965).
  Chemical/Physical. Emits toxic fumes of nitrogen and sulfur oxides when heated to decomposition (Sax and Lewis, 1987).

• 代謝経路

  Methiocarb is oxidised to a sulfoxide and a sulfone in biological media. The resulting two carbamate esters and the parent compound are hydrolysed in soils and plants to the corresponding phenols. Hydroxylation of the N-methyl group on the carbamate function occurs in mammalian preparations in vitro.

• 廃棄物の処理

  In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. Remove material with contaminated soil and place in impervious containers. May be incinerated in a pesticide incinerator at the specified temperature/dwell-time combination. Any liquids, sludges, or solid residues generated should be disposed of in accordance with all applicable federal, state, and local pollution control requirements. If appropriate incineration facilities are not available, material may be buried in a chemical waste landfill. May be amenable to biological treatment at a municipal sewage treatment plant.
