I-Fipronil ebanzi-spectrum insecticide yokulawula izinambuzane nezinambuzane

Incazelo yomkhiqizo

I-Fipronil iyi-insecticide ebanzi ene-spectrum esebenzayo ngokuthintana nokungenwa, esebenza ngempumelelo ngokumelene nezigaba zabantu abadala nezibungu.Iphazamisa isimiso sezinzwa esimaphakathi sesinambuzane ngokuphazamisa i-gamma-aminobutyric acid (GABA) - isiteshi se-chlorine esilawulwayo.I-systemic ezitshalweni futhi ingasetshenziswa ngezindlela ezihlukahlukene.I-Fipronil ingasetshenziswa ngesikhathi sokutshala ukulawula izinambuzane zomhlabathi.Ingasetshenziswa emseleni noma njengebhande elincane.Kudinga ukufakwa ngokuphelele emhlabathini.Ukwakheka okuyimbudumbudu komkhiqizo kungasetshenziswa ekusakazeni izinhlelo zokusebenza ku-paddy rice.Njengokwelashwa kwe-foliar, i-fipronil inokubili umsebenzi wokuvimbela nowokwelapha.Umkhiqizo ubuye ulungele ukusetshenziswa njengokwelashwa kwembewu.I-Fipronil iqukethe i-trifluoromethylsulfinyl moiety ehlukile phakathi kwamakhemikhali e-agrochemicals ngakho-ke okucatshangwa ukuthi ibalulekile ekusebenzeni kwayo okuvelele.

Ezivivinyweni zasensimini, i-fipronil ayizange ibonise i-phytotoxicity ngamanani anconyiwe.Ilawula izinhlobo ze-organophosphate-, carbamate- kanye ne-pyrethroid futhi ifanele ukusetshenziswa ezinhlelweni ze-IPM.I-Fipronil ayihlangani kabi nama-ALS-inhibiting herbicides.

I-Fipronil incipha kancane ezitshalweni futhi ihamba kancane emhlabathini nasemanzini, kanti uhhafu wempilo usukela phakathi kwamahora angama-36 nezinyanga eziyi-7.3 kuye nge-substrate nezimo.Ayinyakazi emhlabathini futhi inamandla aphansi okucwila emanzini angaphansi komhlaba.

I-Fipronil inobuthi obukhulu ezinhlanzini nasezilwanyaneni ezingenamgogodla zasemanzini.Ngalesi sizathu ukulahlwa kwezinsalela ze-fipronil (isb ezitsheni ezingenalutho) emiseleni yamanzi kufanele kugwenywe ngokuphelele.Kunengozi ethile yemvelo yokungcoliswa kwamanzi kusukela ekugelezeni kwamanzi ngemva kokuthelwa emihlambini yezinkomo emikhulu.Kodwa-ke le ngozi iphansi kakhulu kunaleyo ehlotshaniswa nokusetshenziswa kwe-fipronil njengesibulala-zinambuzane sezitshalo.
