説明
Formothion is a pale yellow liquid or crystalline mass,
decomposes on distillation, mp 25–26 ?C, vp 0.113 mPa
(20 ?C). It is poorly soluble in water (2.6 g/L at
24 ?C) and miscible with most organic solvents, except
aliphatic hydrocarbons. Log Kow = 1.47. Formothion is
hydrolyzed in aqueous media to dimethoate (activation)
and dimethoate carboxylic acid (degradation): DT
50 (23 ?C)
at pH 3–9 is less than 1 d.
化学的特性
Formothion is an odorless, yellowish viscous
oil or crystalline mass.
使用
Formothion is used to control sucking pests and internally feeding
larvae in a variety of crops.
一般的な説明
Viscous yellow oil or a crystalline mass. Used as an insecticide and acaricide on crops and ornamentals. Not presently produced commercially in the U.S.
空気と水の反応
hydrolyzed by water especially under alkaline conditions. [EPA, 1998].
反応プロフィール
Organophosphates, such as FORMOTHION, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
危険性
Cholinesterase inhibitor.
健康ハザード
FORMOTHION is one of the least toxic systemic organophosphates. FORMOTHION is a compound of low to moderate toxicity. It causes the depression of cholinesterase, leading to accumulation of acetylcholine in the nervous system, which is believed to be responsible for the symptoms.
火災危険
When heated to decomposition, FORMOTHION emits very toxic fumes of nitrogen oxides, phosphorus oxides and sulfur oxides. FORMOTHION is an organophosphorus insecticide. Some of these materials may burn but none of them ignite readily. Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Avoid alkaline pesticides; hydrolyzed by water especially under alkaline conditions.
农业用途
Insecticide, Acaricide: Formothion is a systemic and contact insecticide
used to control spider mites, aphids, psyllids, mealy bugs,
whiteflies, jassids, leaf miners, ermine moths, and fruit
flies. It is used on tree fruits, vines, olives, hops, cereals,
sugar cane, rice. Formothion is available as an emulsifiable
concentrate and an ultra-low-volume spray. A U.S. EPA restricted Use Pesticide (RUP). Not approved for use in EU
countries

安全性プロファイル
Poison by ingestion,
inhalation, sh contact, and intravenous
routes. Mutation data reported. When
heated to decomposition it emits very toxic
fumes of NOx, POx, and SOx. See also

職業ばく露
Formothion is an insecticide and acar icide for use on crops and ornamentals. Formothion is not
currently produced commercially in the U.S.
代謝経路
Formothion is broken down in aqueous solution to approximately equal
amounts of dimethoate and dimethoate carboxylic acid, the first of which
is an activation step and the latter a degradative one. All studies which
have investigated the fate of formothion in biological systems have
identified these two metabolites but there is evidence that their formation
is purely base-catalysed and not enzyme-catalysed. In this respect, the
amide group of formothion is much more labile than that of dimethoate
since dimethoate carboxylic acid has only been reported in metabolic
studies and is not formed by base-catalysed hydrolysis of dimethoate.
輸送方法
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
不和合性
Strong oxidizers may cause release of
toxic phosphorus oxides. Organophosphates, in the pres ence of strong reducing agents such as hydrides, may form
highly toxic and flammable phosphine gas. Keep away
from alkaline materials.
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 follow ing package label directions or by contacting your local or federal environmental control agency, or by contacting
your regional EPA office.
