I-Cypermetrinyisibulala-zinambuzane esidume kabanzi esihlonishwa kakhulu ngobuchule baso bokuphatha izinhlobonhlobo zezinambuzane eziwuhlupho zasendlini.Isuka ku-1974 futhi yagunyazwa yi-US EPA ngo-1984, i-cypermethrin iyingxenye ye-pyrethroid yezinambuzane ezibulala izinambuzane, elingisa ama-pyrethrins emvelo akhona ezimbalini ze-chrysanthemum.Itholakala ngezindlela ezihlukahlukene ezifana nezimpushana ezimanzi, ukugxilisa uketshezi, uthuli, ama-aerosols, nama-granules, ibonisa ukuguquguquka kuzo zonke izinhlelo zokusebenza ezahlukene.

I-cypermethrin ibulala ini?

Lesi sibulala-zinambuzane esinamandla sihlose izinambuzane eziningi eziwuhlupho ezindaweni ezihlukene, ezihlanganisa izindawo zezolimo nezindawo zasekhaya.Ilwa ngokuphumelelayo nezilokazane zezitshalo ezihlanganisa ama-bollworms, ama-semi-loopers, amacimbi enundu le-diamond back, amathrips, amakhilikithi, umuhlwa, izimbungulu ezinukayo, izikelemu, nezinye.Ngaphezu kwalokho, ibonakala iphumelela ezinambuzaneni ezihlasela izihlahla zokuhlobisa nezihlahlana, kanye nalezo ezihlala ezinqolobaneni zokudla, ezindlini zokugcina izithombo nasezindaweni ezivalekile zezilwane ezifuywayo.Indlela yesenzo ye-Cypermethrin ihlanganisa ukuphazamisa isimiso sezinzwa esimaphakathi sezinambuzane, ukudonselana kwemisipha nokukhubazeka, ngaleyo ndlela kugcine ngokufa kwazo.

I-Cypermethrin ithola umusa phakathi kochwepheshe bokulawula izinambuzane ngenxa yemiphumela yayo ehlala njalo, ngokwakhiwa okuthile okuhlinzeka ngesivikelo kuze kufike ezinsukwini ezingama-90.Nokho, ezinye izithiyo zidinga ukucatshangelwa.Uma isixutshiwe, i-cypermethrin kufanele isetshenziswe ngokushesha ukuze kugwenywe ukuwohloka kwesithako sayo esisebenzayo.Ngaphezu kwalokho, ayinazo izinto ezingaxoshi, okwandisa amathuba okuba izinambuzane zikwazi ukuzulazula ezindaweni ezilashwe kuzo, okwenza kudingeke ukuthi kusetshenziswe amasu ukuqinisekisa ukusabalala okuphelele.

Ingabe i-cypermethrin iphephile kubantu, izinja, namakati?

Mayelana nokuphepha,I-cypermethrin ayilungile kubantu nezilwane ezifuywayo uma isetshenziswa njengoba kuyaliwe, nakuba ubuhlakani bufanelekile.Nakuba ibeka ubuthi obuncane kubantu nasezilwaneni, amakati abonisa ukuzwela okuphakeme kuma-pyrethroids njenge-cypermethrin, okwenza kudingeke ukuthi akhishwe ezindaweni ezilashwayo ngesikhathi nangemva kokufakwa kwesicelo.Ukuthobela imiyalelo yelebula, ukusetshenziswa kwezimpahla zokuzivikela ezifanele ngesikhathi sokufaka isicelo, kanye nesitoreji esiphephile lapho izingane nezilwane ezifuywayo zingakwazi ukufinyelela khona.

Ekuphetheni

I-Cypermethrin ivela njengesibulala-zinambuzane esisebenza ngempumelelo esiziqhayisa ngokusebenza okubanzi ngokumelene nezinambuzane ezidlangile zasendlini kanye nezitha zezitshalo zezolimo.Ukusetshenziswa kwayo ngobuhlakani kuyenza ibe inketho ethandwayo phakathi kwabasebenza ngokulawula izinambuzane nabanikazi bezindlu ngokufanayo, inikeze ukulawula okuhlala njalo kanye nokuvimbela ekungeneni kwezinambuzane ezingamukelekile.

Sisebenza ngokukhethekile ekuhlinzekeni izibulala-zinambuzane kubasabalalisi bezolimo noma abathengisi bezitolo emhlabeni wonke, futhi siyakwazi ukuhlinzeka ngamasampula ekwenziweni okuhlukahlukene.Uma usanemibuzo mayelana ne-cypermethrin, zizwe ukhululekile ukuxhumana nathi.
