説明
Introduced in the 1960s, ethoprop is a nonsystemic
insecticide/nematicide. The mobility of ethoprop in soil
and its half-life are strongly dependent on soil organic
matter (21). It is not known to be carcinogenic and is
available as granules or emulsifiable concentrates.
化学的特性
Ethoprophos is a pale yellow liquid.
使用
Ethoprophos is an organophosphate non-systemic nematicide and soil insecticide. Ethoprophos is an acetylcholinesterase (AChE) inhibitor.
一般的な説明
Ethorop is one of a family of organophosphorus pesticides. Mocap is combustible though Mocap may require some effort to ignite. Mocap is very toxic by skin absorption and inhalation. Mocap may or may not be water soluble.
空気と水の反応
Hydrolyzed in alkali.
反応プロフィール
Organothiophosphates, such as Mocap, 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.
健康ハザード
Mocap is extremely toxic; the probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful for a 150 lb. person. It is a cholinesterase inhibitor which affects the nervous system.
火災危険
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Stable in water. Hydrolyzed in alkali.
农业用途
Nematicide, Insecticide: Ethoprop is used as a pre-plant soil application
to control wireworms and nematodes in potatoes, sugar
cane, sweet potatoes, and tobacco, with lesser usage
on corn (field and sweet), beans (lima and snap), cucumbers,
and cabbage. In addition, it is used to treat
pineapples, bananas, and plantains, as well as fieldgrown
ornamentals and non-bearing citrus trees, and
commercial turf. Roughly 60% of ethoprop is applied
to potatoes.

安全性プロファイル
Poison by ingestion and
skin contact. A cholinesterase inhibitor type
of insecticide. When heated to
decomposition it emits very toxic fumes of
POx and SOx. See also PARATHION.

nematocide and soil insecticide
発がん性
In a combined chronic feeding/
carcinogenicity study, when rats were fed diets with 0, 1, 10,
or 100 ppm ethoprop in the diet for 24 months (equivalent to
0, 0.041, 0.40, or 4.19 mg/kg/day (males); 0, 0.052, 0.51, or
5.12 mg/kg/day (females)), adrenal gland malignant pheochromocytomas
were increased in males and thyroid C-cell
carcinomas were increased slightly in males . When
ethoprop was administered in the diet to mice for 104 weeks
at 0, 0.2, 2.0, or 30 ppm (males: 0, 0.026, 0.254, or 3.96 mg/
kg/day; females: 0, 0.032, 0.318, or 4.9 mg/kg/day), survival
was unaffected at any dose level and no statistically significant
dose-related incidence of tumors were seen in males or
females.
環境運命予測
Soil. The reported half-life in humus-containing soil (pH 4.5) and a sandy loam (pH
7.2–7.3) are 87 and 14–28 days, respectively (Hartley and Kidd, 1987). The rate of
degradation increased in soils that had been treated annually four times (Smelt et al., 1987).
Chemical/Physical. Emits toxic fumes of phosphorus and sulfur oxides when heated
to decomposition (Sax and Lewis, 1987).
代謝経路
Ethoprophos is a soil-acting insecticide and nematicide which is generally
incorporated into the soil in the form of a granular formulation. Volatilisation
is a factor involved in the loss and movement of the compound in
the environment. The major route of degradation of ethoprophos in both
plants and mammals is via hydrolysis to give O-ethyl S-propyl phosphorothioate
through loss of propanethiol. Propanethiol has been shown
to react as a nucleophile to yield ethyl propyl sulfide through attack
on the phosphorus atom and dipropyl disulfide through attack on the
sulfur atom of ethoprophos. The sulfide metabolites are further metabolised
via oxidation to sulfoxides and sulfones. In mammals, an additional
important route of detoxification is through de-ethylation via glutathione-
S-alkyl transferase, a route common to many organophosphorus
insecticides.

不和合性
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, and epoxides. Strong oxidizers may
cause release of toxic phosphorus oxides. Organophosphates,
in the presence 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 following package label directions or by contacting your local or
federal environmental control agency, or by contacting
your regional EPA office
