Beschreibung
Etrimfos is a colorless liquid, mp ?3.35 ?C, vp 6.5 mPa (20 ?C). Solubility in water is 40 mg/L (23–24 ?C). It is miscible with most organic solvents. Log Kow > 3.3. Neat etrimfos is unstable and degrades ca. 40% in 28 d at 50 ?C, but the dilute solutions in nonpolar solvents and its formulations are stable (about 5% loss in 1 y at ca. 20 ?C). It is hydrolyzed in aqueous media; DT₅₀ (25 ?C) at pH 3, 6, and 9 are 0.4, 16, and 14 d, respectively.
Verwenden
Etrimfos is used to control chewing insects in top fruit, vines, olives and a number of other crops. It is also used to control stem borers in rice and insect and acarid pests of stored products.
Verwenden
Satisfar is a pesticide sprayed on plants and vegetables as insecticide to fend off pests.
Verwenden
Agricultural insecticide.
Definition
ChEBI: Etrimfos is an organic thiophosphate.
Hazard
Toxic.
Stoffwechselwegen
Etrimfos is principally degraded in soil and plants via dearylation of etrimfos itself or by hydrolysis of etrimfos oxon to the pyrimidinol (6-ethoxy-4-hydroxy-2-ethylpyrimidine), further metabolism of which involves de-ethylation to a dihydroxypyrimidine (2-ethyl-4,6-dihydroxypyrimidine). In mammals both hydrolysis and demethylation to desmethyl etrimfos are involved in detoxification. Additionally, the ethyl and ethoxy groups of the pyrimidinol hydrolysis product may be hydroxylated and conjugated. Etrimfos oxon is metabolically highly unstable and is often not detected.
Degradation
Etrimfos is unstable when pure but dilute solutions in non-polar solvents and formulations are stable. Half-lives in water at pH 3,6 and 9 were 0.4, 16 and 14 days, respectively. Etrimfos is stable to light (PM).
Toxicity evaluation
The acute oral LD₅₀ for rats is 1,600–1,800 mg/kg. Inhalation LC50 (1 h) for rats is >200 mg/L air. NOEL (2 yr) for rats is 6 mg/kg diet (0.3 mg/kg/d). ADI is 3 μg/kg b.w. The principal degradation pathway in mammals, plants, and soils is pyrimidinyl ester bond cleavage: the major metabolites are 6-ethoxy-4-hydroxy- 2-ethylpyrimidine and its further transformed products. Degradation in mammals involves demethylation to desmethyl etrimfos. The DT₅₀ in soils at pH 6.8 was 3–10 d.
