  殺虫剤

• 説明

  Malathion, a clear amber liquid, is sparingly soluble in water but soluble in a majority of organic solvents. The U.S. Environmental Protection Agency (U.S. EPA) grouped malathion under GUP, meaning general use pesticide. It is used as an insecticide as well as an acaricide for the control of pests. Malathion is used for the control of sucking insects and chewing insects on fruits and vegetables. Malathion is an effective insecticide for the control of several household pests such as houseflies, cockroaches, mosquitoes, aphids, animal ectoparasites, and human head and body lice. Malathion is also found in formulations with many other pesticides.

• 化学的特性

  Malathion is a deep-brown to yellow liquid with a garlic-like odor. Clear and colorless when pure; freezing/melting point5 3C;

• 物理的性質

  Clear, yellow to yellow-orange to brown liquid with an unpleasant garlic, skunk, or mercaptanslike odor

• 使用

  Malathion is used to control a wide spectrum of insect pests in many types of crops and disease vectors in public health programmes. It is also used to control ectoparasites of both humans and animals.

• 定義

  ChEBI: A diester that is butanedioate substituted by a (dimethoxyphosphorothioyl)sulfanediyl group at position 2.

• 適応症

  Malathion (Ovide) is highly effective in the prevention and treatment of pediculosis. It displays 95% ovicidal activity and has no scabicidal activity. It works through cholinesterase inhibition.

• 一般的な説明

  Malathion, 2-[(dimethoxyphosphinothioyl)thio]butanedioic acid diethyl ester, is a water-insolublephosphodithioate ester that has been used as an agriculturalinsecticide. Malathion is a poor inhibitor of cholinesterases.Its effectiveness as a safe insecticide is a result of the differentrates at which humans and insects metabolize the chemical.Microsomal oxidation, which causes desulfuration,occurs slowly to form the phosphothioate (malaoxon),which is 10,000 times more active than the phosphodithioate(malathion) as a cholinesterase inhibitor. Insects detoxifythe phosphothioate by a phosphatase, forming dimethylphosphorothioate, which is inactive as an inhibitor.Humans, however, can rapidly hydrolyze malathion by acarboxyesterase enzyme, yielding malathion acid, a stillpoorer inhibitor of AChE. Phosphatases and carboxyesterasesfurther metabolize malathion acid to dimethylphosphothioate.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  Malathion is a yellow to brown liquid that solidifies at 2.9° C, moderately toxic. Organic phosphate insecticide, acts as an inhibitor of cholinesterase. When heated to decomposition Malathion emits toxic fumes of oxides of sulfur and phosphorus [Lewis, 3rd ed., 1993, p. 789].

• 危険性

  Absorbed by skin, cholinesterase inhibitor. Questionable carcinogen.

• 健康ハザード

  Cholinesterase inhibitor; toxic propertiessimilar to those of parathion; however,less toxic than parathion; moderately toxicby ingestion and possibly other routes ofexposure; toxic symptoms include excessivesalivation, lacrimation, blurred vision, con-striction of the pupils, nausea, vomiting,abdominal pain, and difficulty in breathing;also coma and death can result form largeintake; ingestion of 10–25 g could be fatalto adult humans; skin contact can produceallergic sensitization reaction; also absorbedthrough skin, causing systemic poisoning;experimental teratogen; LD50 data reportedin the literature show wide variation.
  LD50 oral (rate): 300–2800 mg/kg
  LD50 skin (mouse): 2000–3000 mg/kg
  Benslama et al. (2004) have reported twounusual cases of malathion poisoning with arare-type of complication from “intermediatesyndrome” arising 2 to 4 days after the onsetof cholinergic effects. The symptoms wererespiratory paresis with difficulties of wean-ing from assisted respiratory, deficit of proximal limbs, neck flexors and cranial nerves.The authors attributed this syndrome to pro-longed inhibition of acetyl-cholinesterasesand not to any muscular fiber’s necrosis.

• 使用上の注意点

  • 散布時は手袋やマスクを着用し、目や鼻、肌に直接かからないように注意が必要です。
  • 農作物の受粉を助けるためのミツバチに影響が出るため、ミツバチを放飼中の施設では使用をさける必要があります。また、近隣で養蜂をおこなっている場合、関係機関に情報を提供する必要があります。
  • 1回の栽培において、使用回数が定められているため注意が必要です。また、マラソンの成分を含む農薬の総使用回数も定められているため、全体の農薬使用回数も制限があります。
  • 河川や湖、沼などの水産動植物に影響を及ぼすため、河川や養殖池などに飛散、流入しないように注意が必要です。また、薬剤の使用残りや容器の洗浄水は河川等に流してはいけません。

• 使用用途

  マラソンの使用用途は、害虫の防除です。即効性があり早く防除の効果がでることと、多くの農作物と害虫に登録があることが大きな特徴です。

  効果的に防除できる害虫として、野菜類や花き類に発生するアブラムシやハダニ類、イネに発生するツマグロヨコバイやウンカ類、果樹に発生するアブラムシやケムシ類、カイガラムシ類、豆類に発生するハダニ類やコガネムシ類が挙げられます。

  有機リン系の殺虫剤の場合、アブラナ科の農作物に散布すると、薬害がでるため使用ができないことがあります。しかし、マラソンはキャベツやブロッコリー、ハクサイなどのアブラナ科の農作物にも登録があるため使用可能です。

  マラソンには葉や茎から吸収されて、植物体に広がっていく浸透移行性があります。そのため、直接農薬が当たらなかった害虫で、葉や果実をなめたり、口にする害虫にも効果的です。

• 农业用途

  nsecticide: Not approved for use in EU countries. Malathion is a non-systemic, wide-spectrum organophosphate insecticide. It was one of the earliest organophosphate insecticides developed (introduced in 1950). Malathion is suited for the control of sucking and chewing insects on fruits, vegetables, citrus, cotton, corn, sorghum, ornamentals and stored products, and is also used to control mosquitoes, flies, household insects, farm and livestock parasites (ectoparasites), and head and body lice. Malathion may also be found in formulations with many other pesticides; the U.S. EPA lists 2,283 current and canceled labels of products containing malathion. Malathion is marketed as 99.6% technical grade liquid. Available formulations include wettable powders (25% and 50%), emulsifiable concentrates, dusts and aerosols.

• 輸送方法

  UN2783 Organophosphorus pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

• 不和合性

  Reacts violently with strong oxidizers, magnesium, alkaline pesticides. Attacks metals including iron, steel, tin plate; lead, copper; and some plastics, coatings, and rubbers

• 廃棄物の処理

  Malathion is reported to be “hydrolyzed almost instantly” at pH 12; 50%; hydrolysis at pH 0 requires 12 hours. Alkaline hydrolysis under controlled conditions (0.5 n NaOH in ethanol) gives quantitative yields of (CH3O)2P(S)SNa, whereas hydrolysis in acidic media yields (CH3O)2P(S)OH. On prolonged contact with iron or iron-containing material, it is reported to break down and completely lose insecticidal activity. Incineration together with a flammable solvent in a furnace equipped with afterburner and scrubber is recommended. 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
