I-Acaricide ye-Bifenazate yokulawula izinambuzane zokuvikela izitshalo

Incazelo yomkhiqizo

I-Bifenazate iyi-acaricide ethintana naye esebenza ngokumelene nazo zonke izigaba zokuphila zesicabucabu, izibungu ezibomvu nezotshani, kuhlanganise namaqanda.Inomphumela wokuwisa ngokushesha (imvamisa engaphansi kwezinsuku ezi-3) kanye nomsebenzi oyinsalela eqabungeni othatha amaviki ama-4.Umsebenzi womkhiqizo awuncikile ekushiseni - ukulawula akuncishisiwe emazingeni okushisa aphansi.Ayilawuli ukugqwala, izibungu eziyisicaba noma ezibanzi.

Ucwaningo kuze kube manje luphakamisa ukuthi i-bifenazate yenza njenge-GABA (i-gamma-aminobutyric acid) emelene ne-peripheral nervous system ku-neuromuscular synapse ezinambuzaneni.I-GABA iyi-amino acid ekhona ohlelweni lwezinzwa lwezinambuzane.I-Bifenazate ivimba iziteshi ze-chloride ezicushwe yi-GABA, okuholela ekusaseni ngokweqile kwezinhlelo zezinzwa eziseceleni zezinambuzane ezisengozini.Le ndlela yokwenza kubikwa ukuthi ihlukile kuma-acaricides, okuphakamisa ukuthi umkhiqizo ungadlala indima ebalulekile esikhathini esizayo kumasu okulawula ukumelana nezibungu.

Kuyi-acaricide ekhetha kakhulu elawula isicabucabu, i-Tetranychus urticae.I-Bifenazate iyisibonelo sokuqala se-carbazate acaricide.Inoncibilika emanzini aphansi, iyaguquguquka futhi ngeke kulindeleke ukuthi ingene emanzini angaphansi komhlaba.I-Bifenate nayo akulindelekile ukuthi iqhubeke nezinhlelo zenhlabathi noma zamanzi.Iyingozi kakhulu ezilwaneni ezincelisayo futhi iyacisha isikhumba, iso kanye nesistimu yokuphefumula.Inobuthi obusesilinganisweni ezilwaneni eziningi zasemanzini, izinyosi nezikelemu.

Ucwaningo olwenziwa eNyuvesi yaseFlorida ngasekupheleni kwawo-1990 luthombe ukuvela okungenzeka kokumelana ne-abamectin ezibungwini ezinamachashaza amabili kumasitrobheni;I-bifenazate ingase inikeze enye indlela yokwelapha.

Ezivivinyweni zasensimini, akukho phytotoxicity okubikiwe, ngisho namazinga amakhulu kakhulu kunalawo anconyiwe.I-Bifenazate iyacasula iso ngokumaphakathi futhi ingase ibangele ukungezwani nesikhumba.I-Bifenazate ihlukaniswa njengengenabo ubuthi ezilwaneni ezincelisayo ezincane ngesisekelo somlomo obukhali.Inobuthi emvelweni yasemanzini futhi inobuthi kakhulu ezintweni zasemanzini ezinemiphumela ehlala isikhathi eside.
