• 개요

  Acetamide acid (methomyl) is a carbamate broad-spectrum insecticide. Methomyl is classified as a restricted use pesticide (RUP). It is a crystalline solid with a slight sulphurous odour and very soluble in methanol, acetone, ethanol, and isopropanol. It decomposes with heat and releases hazardous gases/vapours, such as sulphur oxides, methyl isocyanate, and HCN. Acetamide acid (methomyl) is used both as a contact insecticide and as a systemic insecticide. It is used as an acaricide to control ticks and spiders; as fly bait; for foliar treatment of vegetable, fruit, field crops, cotton, and commercial ornamentals; and in and around poultry houses and dairies.

• 화학적 성질

  Methomyl is a white crystalline solid with a slight sulfurous odor. A noncombustible solid, that may be dissolved in flammable liquids that may alter physical properties listed here.

• 용도

  Methomyl is a pesticide. This mixture of two stereoisomers is used as a foliar spary to control field crops, stables and poultry houses, and in glasshouses on ornamentals and vegetables, or in flypapers. Cases have been reported in chrysanthemum growers and in two women working in a plant nursery.

• 정의

  ChEBI: A carbamate ester obtained by the formal condensation of methylcarbamic acid with the hydroxy group of 1-(methylsulfanyl)acetaldoxime.

• 일반 설명

  White crystalline solid with slight sulfurous smell. Used as a nematocide, and an insecticide on vegetables, tobacco, cotton, alfalfa, soy beans, and corn.

• 공기와 물의 반응

  Water soluble.

• 반응 프로필

  Methomyl 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.

• 위험도

  Toxic by ingestion. Acetyl cholinesterase inhibitor, male reproductive damage, and hematologic effects. Questionable carcinogen.

• 건강위험

  Methomyl has high oral toxicity, moderate inhalation toxicity and low skin toxicity. The probable oral lethal dose for humans is between 7 drops and 1 teaspoon for a 150 pound adult. Death is due to respiratory arrest.

• 화재위험

  When heated to decomposition, Methomyl emits very toxic fumes of nitrogen oxides and sulfur oxides. Do not subject liquid formulations to temperatures below 32F.

• 농업용

  Insecticide, Acaricide: Methomyl is a broad-spectrum insecticide that is particularly effective against organophosphorus-resistant pests. It is used as an acaricide to control ticks and spiders. It is used for foliar treatment of vegetable, fruit and field crops, tobacco, cotton, commercial ornamentals, and in and around poultry houses and dairies. It is also used as a fly bait. Methomyl is effective as a “contact insecticide,” because it kills target insects upon direct contact, and also as a “systemic insecticide” because of its capability to cause overall “systemic” poisoning in target insects, after it is absorbed and transported throughout the pests that feed on treated plants. It is capable of being absorbed by plants without being “phytotoxic” or harmful, to the plant. A U.S. EPA restricted Use Pesticide (RUP).

Cases were reported in chrysanthemum growers and in two women working in a plant nursery

• Safety Profile

  Poison by ingestion, inhalation, and subcutaneous routes. Mildly toxic by skin contact. Wen heated to decomposition it emits very toxic fumes of NOx and SOx.

• 잠재적 노출

  Methomyl is a broad-spectrum insecticide used as insecticide in many vegetables, field crops; certain fruit crops; and ornamentals.
  Incompatibilities: Keep away from strong bases, strong oxidizers. Heat causes decomposition forming toxic and irritating fumes including nitrogen oxides; sulfur oxides; hydrogen cyanide; methylisocyanate

• 환경귀착

  Biological. From the first-order biotic and abiotic rate constants of methomyl in estuarine water and sediment/water systems, the estimated biodegradation half-lives were 75–165 and 39–134 days, respectively (Walker et al., 1988).
  Soil. Harvey and Pease (1973) reported that methomyl dissipated rapidly in fine sand and loamy sand soils. One month following application to a Delaware soil, 1.8% of the applied dosage was recovered and after 1 year, methomyl was not detected. T
  Groundwater. According to the U.S. EPA (1986) methomyl has a high potential to leach to groundwater.
  Plant. The reported half-lives of methomyl on cotton plants, mint plants and Bermuda grass were 0.4–8.5, 0.8–1.2 and 2.5 days, respectively (Willis and McDowell, 1987).
  Chemical/Physical. Emits toxic fumes of nitrogen and sulfur oxides when heated to decomposition (Sax and Lewis, 1987; Lewis, 1990).

• 저장

  Acetamidic acid (methomyl) should be kept stored in a sealed container in a cool (below 0 ° C), dry, area with adequate ventilation. The chemical should be kept away from incompatible chemical substances, strong oxidizing agents, strong bases, other pesticides, and food or feed.

• 폐기물 처리

  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. Alkaline hydrolysis leads to complete degradation to nontoxic products. May be dissolved in water and sprayed into a furnace with effluent gas scrubbing also. In accordance with 40CFR165, follow 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.

• 주의 사항

  Occupational workers should avoid contact of acetamidic acid (methomyl) with the skin, eyes, or clothing, and avoid exposures to vapor or mist. Workers should be careful when storing and/or disposing of acetamidic acid, avoid the dust contaminating water, food, or feed by storage or disposal. Workers should use respiratory protection: Government approved respirator. Hand Protection: Compatible chemical-resistant gloves. Eye Protection: Chemical safety goggles.chemical safety goggles.
