化学的特性
Fonofos is a highly toxic compound. It is sparingly soluble in water, but soluble in acetone, ethanol, xylene, and kerosene. It has been grouped by the US EPA under RUP and hence requires special handling by qualifi ed, certifi ed, and trained workers. Fonofos was used as a soil insecticide, which resulted in its direct release to the environment. It was primarily used on corn crops, sugar cane, peanuts, tobacco, turf, and some vegetable crops. It controls aphids, corn borer, corn root-worm, corn wire-worm, cutworms, white grubs, and some maggots. Formulations of fonofos include granular, microgranular, emulsifi able concentrate, suspension concentrate, microcapsule suspension, and for seed treatment
使用
Fonofos is used to control soil insects in a number of crops and in
turf.
一般的な説明
Light-yellow liquid with a pungent mercaptan-like odor. Used primarily as an insecticide for corn.
空気と水の反応
Very slightly soluble in water.
反応プロフィール
Organothiophosphates, such as FONOFOS, 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. It is sparingly soluble in water but soluble in acetone, ethanol, xylene, and kerosene.
危険性
Cholinesterase inhibitor.
健康ハザード
FONOFOS is a cholinesterase inhibitor. It can cause severe symptoms and death from respiratory arrest.
火災危険
When FONOFOS is heated to decomposition, FONOFOS can emit highly toxic fumes of phosphorus oxides.
农业用途
Insecticide: It is a soil organophosphate insecticide primarily
used on corn. It was also used on maize, cereals, sorghum,
fruit, olives, potatoes, sugar cane, peanuts, tobacco, turf,
and some vegetable crops. It controls aphids, corn borer,
corn rootworm, corn wireworm, cutworms, white grubs,
symphylins, and other soil pests including some maggots. It was available in granular, microgranular, emusifiable concentrate, suspension concentrate, microcapsule
suspension, and seed treatment. Not registered for use
in the U.S. or in EU countries. There are 16 global
suppliers.

安全性プロファイル
Poison by ingestion and
skin contact. An insecticide. When heated to
decomposition it emits very toxic fumes of POx and SOx.
職業ばく露
A potential danger to those involved
in the manufacture, formulation and application of this soil
insecticide which is used for control of corn rootworms,
wireworms, cutworms, symphylins, and other soil pests.
Incompatibilities: Strong acids, alkalies.
環境運命予測
Soil. The half-life for fonofos in soil incubated in the laboratory under aerobic conditions ranged was 25 days (Lichtenstein et al., 1977). In field soils, the half-lives for fonofos ranged from 24 to 102 days (Kiigemgi and Terriere, 1971; Schulz and Lichtenstein, 1971; Mathur et al., 1976; Talekar et al., 1977).
Plant. In plants, fonofos is oxidized to the phosphonothioate (Hartley and Kidd, 1987). Oat plants were grown in two soils treated with [14C]fonofos. Most of the residues remained bound to the soil. Less than 2% of the applied [14C]fonofos was re
Chemical/Physical. The hydrolysis half-lives of fonofos in a sterile 1% ethanol/water solution at 25°C and pH values of 4.5, 5.0, 6.0, 7.0 and 8.0, were 87, 50, 41, 22 and 6.9 weeks, respectively (Chapman and Cole, 1982). Emits toxic nitrogen and
代謝経路
The metabolism of fonofos in plants and animals follows similar pathways,
with both activation and degradative steps occurring as primary
metabolic events. The former involves oxidative desulfuration to the
active acetylcholinesterase inhibitor fonofos oxon. The oxon is hydrolysed
rapidly in most biological systems and the resulting thiophenol is very
rapidly metabolised via S-methylation, thiooxidation, ring hydroxylation
and conjugation.
