Uses
Flufenoxuron is used for the control of many phytophagous mites
(Aculus, Brevipalpus, Pananychus, Phyllocoptuuta, Tetuanychus, spp) and
insect pests on pome fruit, vines, citrus, tea, cotton, maize, vegetables and
ornamentals. It is also used as a public hygiene insecticide.
Uses
Flufenoxuron is an known insecticide and acts as an insect growth regulator by inhibiting chitin synthesis.
Definition
ChEBI: Flufenoxuron is a benzoylurea insecticide, a member of monochlorobenzenes, a member of (trifluoromethyl)benzenes, a member of monofluorobenzenes and a difluorobenzene. It has a role as a mite growth regulator. It derives from a diphenyl ether.
Metabolic pathway
Information on the metabolism of flufenoxuron is avilable in a Pesticides
Safety Directorate review of its use as a public hygiene insecticide (PSD).
Degradation
The DT
50 of flufenoxuron (25 °C) was 267 days at pH 7,206 days at pH 5
and 36.7 days at pH 9 (PM).
Flufenoxuron underwent photodegradation to form 2,6-difluorobenzamide
(2), the urea derivative 3 and the 4-aminodiphenyl ether 4 in
aqueous solution under natural sunlight in the UK (PSD, 1995).
Mode of action
Flufenoxuron acts in a similar manner to diflubenzuron, reducing chitin incorporation in the cuticJe (Clarke and Jewess 1990). It has cuticular and stomach action. It has ovo-Iarvicidal activity. Treated adults lay non-viable eggs (Tomlin 1995).
