Umahluko phakathi kwePermethrin kunye neDinotefuran

I. Permethrin

1. Iimpawu ezisisiseko

I-Permethrin yi-synthetic insecticide, kwaye isakhiwo sayo sekhemikhali siqulethe isakhiwo seempawu ze-pyrethroids. Idla ngokuba lulwelo olunamafutha atyheli olukhanyayo olungenambala olunevumba elikhethekileyo. Ayinyibiliki emanzini, i-soluble ngokulula kwii-solvents eziphilayo, izinzile ekukhanyeni, kodwa iyakwazi ukubola phantsi kweemeko ze-alkaline.

2. Usetyenziso oluphambili

Kwezolimo: Ingasetyenziselwa ukulawula izitshabalalisi ezahlukeneyo zezolimo, ezinje ngezomqhaphu, imifuno, imithi yeziqhamo kunye nezinye izityalo.

Ngokolawulo lwezinambuzane zococeko: Inempembelelo entle yokulawula izitshabalalisi zococeko ezifana neengcongconi, iimpukane, iintakumba neentwala, kwaye ingasetyenziselwa ukulawula izinambuzane emakhayeni, kwiindawo zikawonke-wonke, njl.

II.I-Dinotefuran

1. Iimpawu ezisisiseko

I-Dinotefuraniyeyesithathu isizukulwana se-neonicotinoid zinambuzane. Kubonakala njengomgubo omhlophe wekristale.

2. Usetyenziso oluphambili

Kwezolimo, isetyenziswa ikakhulu ukulawula iintwala, iihoppers, iplanthoppers, thrips, whiteflies kunye nobunzima bazo obuxhathisayo kwizityalo ezahlukeneyo ezifana nengqolowa, irayisi, umqhaphu, imifuno, imithi yeziqhamo kunye namagqabi ecuba. Kwangaxeshanye, iyasebenza kakhulu ngokuchasene neColeoptera, Diptera, Lepidoptera kunye nezinambuzane zehomoptera. Isenokusetyenziswa ukulawula izitshabalalisi zasemakhaya ezifana namaphela. Yibeke kwiikona okanye kwimingxuma apho amaphela ahlala ebonakala khona, njengasemva kweekhabhinethi kunye nezixhobo zombane, kwaye uthathe ithuba lokungena okunamandla ukuphumeza umphumo wokuphelisa amaphela.

III. Umahluko phakathi kwePermethrin kunye neDinotefuran

1. Ngokuphathelele ubutyhefu

Ngokuphathelele ukuthelekisa amanqanaba etyhefu kwezi zimbini, izifundo ezahlukeneyo kunye neemeko zesicelo zinokuvelisa iziphumo ezahlukeneyo. Uphononongo lubonise ukuba i-furosemide inetyhefu ephantsi kwaye ingasetyenziswa ixesha elide. Nangona kunjalo, i-cyfluthrin (efana ne-cyfluthrin) inetyhefu kakhulu kwaye akufanele isetyenziswe ixesha elide. Kodwa uthelekiso oluthile lwetyhefu phakathi kwe-cyfluthrin kunye ne-furfuramide lusafuna uphando olukhethekileyo ngakumbi ukumisela.

2. Ngokuphathelele kwindlela yokwenza

I-Permethrin iphazamisa kakhulu inkqubo ye-neural conduction yezinambuzane, ezithintela ukuhamba ngokuqhelekileyo kwaye ekugqibeleni zibangele ukufa kwazo. I-Furfuran isebenza ngokuphazamisa inkqubo yemetabolism yamaphela (ukuthatha amaphela njengomzekelo, indlela yokusebenza kwayo ngokuchasene nezinye izitshabalalisi ziyafana), zithintela ukukhula kunye nokuzala ngokuqhelekileyo. Ikwanazo neziphumo ezigqwesileyo zolawulo kwizinambuzane ezigqobhozayo ezifunxa umlomo kwaye ibonise umsebenzi wokubulala izinambuzane kwidosi ephantsi kakhulu.

3. Ngokumalunga nezinto zokuthintela nokulawula

IPermethrin isetyenziswa ikakhulu ukulawula izitshabalalisi ezifana neengcongconi, iimpukane, iintakumba kunye neentwala. Kwezolimo, inokulawula izitshabalalisi zezityalo ezahlukeneyo. IFumefon isetyenziswa kakhulu ekulweni iintwala, izinambuzane ezitya amagqabi, iiplanthoppers kunye nezinye izitshabalalisi ezifunxa izityalo ezahlukeneyo. Ikwanazo nefuthe elihle lokulawula izitshabalalisi zasemakhaya ezifana namaphela. Ngaphezu koko, inempembelelo engcono yokulawula izinambuzane eziye zavelisa ukuchasana ne-nicotinoid agents.
