Flupyrazofos Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Water solubility of flupyrazofos is 0.8 mg/L. Log
Kow = 5.24. Flupyrazofos is slowly hydrolyzed in aqueous
media; DT
50 at pH 4, 7, and 9 are 266, 180, and
121 h, respectively. Vp 3.7 mPa (25 ?C). Flupyrazofos is
a nonsystemic insecticide used for the control of caterpillars,
especially diamondblack moth, Plutella xylostella,
larvae.
Verwenden
Flupyrazofos is a new pyrazole organophosporus insecticide, which has a high activity against the diamond-back moth (Plutella xylostella).
Stoffwechselwegen
The principal route of metabolism of flupyrazofos is by oxidative
desulfuration to the oxon which is hydrolysed, principally via base rather
than esterase catalysis, to 1-phenyl-3-trifluoromethyl-5-hydroxypyrazole.
The physico-chemical parameters of flupyrazofos, including water solubility,
hydrolysis rates, vapour pressure and octanol/water partition
coefficients, have been reported by Kim et al. (1997).
Stoffwechsel
The principal
route of metabolism of flupyrazofos is by oxidative
desulfuration to the oxon, followed by hydrolysis to 1-
phenyl-3-trifluoromethyl-5-hydroxypyrazole and diethyl
hydrogen phosphate. Flupyrazofos is degraded in soil with
DT
50 of about 14 d.
