Beschreibung
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.
Chemische Eigenschaften
Formothion is an odorless, yellowish viscous
oil or crystalline mass.
Verwenden
Formothion is used to control sucking pests and internally feeding
larvae in a variety of crops.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
hydrolyzed by water especially under alkaline conditions. [EPA, 1998].
Reaktivität anzeigen
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.
Hazard
Cholinesterase inhibitor.
Health Hazard
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.
Brandgefahr
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.
Landwirtschaftliche Anwendung
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

Sicherheitsprofil
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
ESTERS.
mögliche Exposition
Formothion is an insecticide and acar icide for use on crops and ornamentals. Formothion is not
currently produced commercially in the U.S.
Stoffwechselwegen
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.
Versand/Shipping
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Inkompatibilitäten
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.
Waste disposal
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.
