Isibulali zinambuzane iTetramethrin Mosquito 95%Tc Ukulawula Iingcongconi Iimpukane Amaphela

I-Tetrametrin isetyenziswa kakhulu ngamandlaeyenziweyoIsibulali zinambuzanekusapho lwepyrethroid.Iqinile yikristale emhlophe.Imveliso yorhwebo ngumxube we-stereoisomers.Idla ngokusetyenziswa njengeisibulali zinambuzane, kwaye ichaphazela inkqubo yemithambo-luvo yesi sinambuzane.Inokufumaneka kwiindawo ezininziIsibulali-zinambuzane saseKhayaiimveliso.Ifomula yobungqina nguC19H25NO4;ubunzima bemolekyuli yi-331.4.Ubume bayo yikristale engenambala;ubunzima bayo obuthile yi-1.1 ku-20 ° C;uxinzelelo lwalo lomphunga yi-0.944 mPa kwi-30 ° C;logKow= 4.6.Ayinyibiliki kancinane (1.83 mg/l) emanzini kwi-25°C, kodwa iyanyibilika kwiintlobo ezininzi ze-organic solvents.Ayizinzile kwi-asidi eyomeleleyo kunye ne-alkaline medium.

Isicelo

Isantya salo sokuwisa iingcongconi, iimpukane njl.njl. siyakhawuleza.Ikwanalo nesenzo sokugxotha amaphela.Idla ngokuyilwa ngezibulali-zinambuzane ezinamandla amakhulu okubulala.Inokwenziwa ukuba ibe sisitshizi sokubulala izinambuzane kunye nesibulali sezinambuzane esineaerosol.

Ubutyhefu

I-Tetramethrin sisitshabalalisi esinetyhefu ephantsi.Acute percutaneous LD50 kwimivundla>2g/kg.Akukho ziphumo ezicaphukisayo kulusu, amehlo, impumlo, kunye nephecana lokuphefumla.Ngaphantsi kweemeko zovavanyo, akukho mutagenic, carcinogenic, okanye iziphumo zokuzala zabonwa.Le mveliso inetyhefu kwiintlanzi i-Chemicalbook, ene-carp TLm (iiyure ezingama-48) ze-0.18mg / kg.Igill eluhlaza okwesibhakabhaka LC50 (iiyure ezingama-96) yi-16 μ G/L.Izagwityi acute oral LD50>1g/kg.Ikwayityhefu kwiinyosi nakwimibungu yesilika.
