Applications:
Biochemistry Oxidative removal in vivo of the N-ethoxymethyl group generates the active species, which is a mitochondrial uncoupler.Mode of action Insecticide acaricide with mainly stomach some contact action.Exhibits good translaminar but limited systemic activity in plants.Uses Control of many species of insects mites, including those resistant to carbamate,ganophosphate pyrethroid insecticides also chitin-synthesis inhibitors, in cotton, vegetables, citrus, top fruit, vines soya beans.Among pests resistant to conventional products which are controlled by chlorfenapyr are Brevipalpus phoenicis (leprosis mite), Leptinotarsa decemlineata (Colorado potato beetle), Helicoverpa spp., Heliothis spp., Plutella xylostella (diamond-back moth) Tetranychus spp.Its use in resistance management programmes fcontrol of various cotton pests is under evaluation.Phytotoxicity No phytotoxicity observed at field use rates.

Mode of action:
Chlorfenapyr is a new kind of pyrrole insecticide acaricedes with dual function of stomach
Poison contact insecticide.The mechanism of function mechanism is:By hindering the breath function of insect's mitochondrial to stop the cell's life activity.After using it, the insect
Becomes weakly, spot appears, colchanges, activity stops, stupor, leads to death finally.Chlorfenapyr is safe fcrops, it can be used in entire activity period of harmful insect, but still suggested that using it as early as possible, using in egg hatch stage low age larval stage is better.To the more serious tolerantly harmful insect should pray chlorfenapyr to the eaten part of leaf surface evenly to the insect body directly.
