Umahluko phakathi kwePermethrin kunye neDinotefuran

I. I-Permethrin

1. Iimpawu ezisisiseko

I-Permethrin sisibulali-zinambuzane esenziwe ngokwenziwa, kwaye ulwakhiwo lwayo lweekhemikhali lunesakhiwo esikhethekileyo seekhompawundi ze-pyrethroid. Ihlala ilulwelo olunamafutha olungenambala ukuya kolukhanyayo olunevumba elikhethekileyo. Ayinyibiliki emanzini, inyibilika lula kwizinyibilikisi ze-organic, izinzile ekukhanyeni, kodwa idla ngokubola phantsi kweemeko ze-alkaline.

2. Iindlela eziphambili zokusetyenziswa

Kwezolimo: Ingasetyenziselwa ukulawula izinambuzane ezahlukeneyo zezolimo, ezifana nezo zikwikotoni, imifuno, imithi yeziqhamo kunye nezinye izityalo.

Ngokuphathelele ulawulo lwezinambuzane olucocekileyo: Lunempembelelo entle yokulawula izinambuzane ezicocekileyo ezifana neengcongconi, iimpukane, iintakumba kunye neentwala, kwaye lungasetyenziselwa ulawulo lwezinambuzane emakhaya, kwiindawo zikawonke-wonke, njl. Ngeendlela ezifana nokutshiza okuseleyo, umngcipheko wokuzala kwezinambuzane kunye nokudluliselwa kwezifo unokuncipha.

II.I-Dinotefuran

1. Iimpawu ezisisiseko

I-DinotefuranIkwisizukulwana sesithathu se-neonicotinoid insecticides. Ibonakala njengomgubo omhlophe wekristale.

2. Iindlela eziphambili zokusetyenziswa

Kwezolimo, isetyenziswa kakhulu ukulawula ii-aphids, ii-leafhoppers, ii-planthoppers, ii-thrips, ii-whiteflies kunye neentlobo zazo ezixhathisayo kwizityalo ezahlukeneyo ezifana nengqolowa, irayisi, umqhaphu, imifuno, imithi yeziqhamo kunye namagqabi ecuba. Kwangaxeshanye, isebenza kakhulu kwizinambuzane zeColeoptera, iDiptera, iLepidoptera kunye ne-homoptera. Ingasetyenziselwa nokulawula izinambuzane zasekhaya ezifana nee-cockroaches. Yibeke kwiikona okanye kwiindawo apho ii-cockroaches zivela khona rhoqo, njengasemva kweekhabhathi kunye nezixhobo zombane, kwaye usebenzise ithuba lokungena kwayo ngamandla ukuze ufezekise isiphumo sokuphelisa ii-cockroaches.

III. Umahluko phakathi kwePermethrin kunye neDinofuran

1. Ngokuphathelele ubuthi

Ngokuphathelele uthelekiso lwamanqanaba obuthivu kula mabini, izifundo ezahlukeneyo kunye neemeko zokusetyenziswa zinokuvelisa iziphumo ezahlukeneyo. Izifundo zibonise ukuba i-furosemide inetyhefu ephantsi kwaye ingasetyenziswa ixesha elide. Nangona kunjalo, i-cyfluthrin (efana ne-cyfluthrin) inetyhefu ngakumbi kwaye akufuneki isetyenziswe ixesha elide. Kodwa uthelekiso oluthile lobuthivu phakathi kwe-cyfluthrin kunye ne-furfuramide kusafuna uphando olukhethekileyo ukuze kuchongwe.

2. Ngokuphathelele indlela yokusebenza

I-Permethrin iphazamisa kakhulu inkqubo yokuhambisa imithambo-luvo yezinambuzane, izithintela ukuba zingashukumi ngendlela eqhelekileyo kwaye ekugqibeleni ibangele ukufa kwazo. I-Furfuran isebenza ngokuphazamisa inkqubo ye-metabolic yezinambuzane (xa sijonga ii-cockroaches njengomzekelo, indlela esebenza ngayo ngokuchasene nezinye izinambuzane iyafana), izithintela ekukhuleni nasekuzaleni ngendlela eqhelekileyo. Ikwaneziphumo ezilungileyo zokulawula izinambuzane ezifunxa umlomo kwaye ibonisa umsebenzi ophezulu wokubulala izinambuzane kwiidosi eziphantsi kakhulu.

3. Ngokuphathelele iinjongo zokuthintela nokulawula

I-Permethrin isetyenziswa kakhulu ukulawula izinambuzane ezifana neengcongconi, iimpukane, iintakumba kunye neentwala. Kwezolimo, inokulawula izinambuzane ezahlukeneyo zezityalo. I-Fumefon isetyenziswa kakhulu ukulawula ii-aphids, ii-leafhoppers, ii-planthoppers kunye nezinye izinambuzane ezifunxayo kwizityalo ezahlukeneyo. Ikwanayo nempembelelo entle yokulawula izinambuzane zasekhaya ezifana nee-cockroaches. Ngaphezu koko, inempembelelo engcono yokulawula izinambuzane eziye zakwazi ukumelana nee-nicotinoid agents.
