Umehluko phakathi kwePermethrin neDinotefuran

I. I-Permethrin

1. Izakhiwo eziyisisekelo

I-Permethrin iyi-insecticide yokwenziwa, futhi isakhiwo sayo samakhemikhali siqukethe isakhiwo sesici se-pyrethroid compounds. Ngokuvamile kuba uketshezi olunamafutha aphuzi olukhanyayo olungenambala olunephunga elikhethekile. Ayincibiliki emanzini, ikwazi ukuncibilika kalula kuzincibilikisi zemvelo, izinze ekukhanyeni, kodwa ijwayele ukubola ngaphansi kwezimo ze-alkali.

2. Ukusetshenziswa Okuyinhloko

Kwezolimo: Ingasetshenziswa ukulawula izinambuzane ezinhlobonhlobo zezolimo, njengalezo ezikotini, imifino, izihlahla zezithelo nezinye izitshalo.

Ngokuphathelene nokulawulwa kwezinambuzane ngokuhlanzekile: Kunomphumela omuhle wokulawula izinambuzane ezihlanzekile ezifana nomiyane, izimpukane, amazeze nezintwala, futhi ingasetshenziswa ekulawuleni izinambuzane ezindlini, ezindaweni zomphakathi, njll. Ngezindlela ezinjengokufafaza okuyinsalela, ingozi yokuzalanisa izinambuzane nokudluliselwa kwezifo ingancishiswa.

II.I-Dinotefuran

1. Izakhiwo eziyisisekelo

I-Dinotefuraningeyesizukulwane sesithathu se-neonicotinoid insecticides. Kubonakala njengempushana emhlophe ecwebezelayo.

2. Ukusetshenziswa Okuyinhloko

Kwezolimo, isetshenziswa kakhulu ukulawula ama-aphid, ama-leafhoppers, ama-planthopper, ama-thrips, ama-whiteflies kanye nezinhlobo zawo ezimelana nezitshalo ezahlukahlukene ezifana nokolweni, irayisi, ukotini, imifino, izihlahla zezithelo namaqabunga kagwayi. Ngesikhathi esifanayo, iphumelela kakhulu ngokumelene nezinambuzane ze-Coleoptera, i-Diptera, i-Lepidoptera ne-homoptera. Ingasetshenziswa futhi ukulawula izinambuzane zasekhaya njengamaphela. Ibeke emakhoneni noma emifantwini lapho amaphela evame ukuvela khona, njengangemuva kwamakhabethe nezinto zikagesi, futhi usebenzise ithuba lokungena kwayo okuqinile ukuze uzuze umphumela wokuqeda amaphela.

III. Umehluko phakathi kwePermethrin neDinotefuran

1. Mayelana nobuthi

Ngokuphathelene nokuqhathaniswa kwamazinga obuthi kokubili, izifundo ezihlukene nezimo zokusetshenziswa kungase kuveze imiphumela ehlukene. Ucwaningo luye lwabonisa ukuthi i-furosemide inobuthi obuphansi futhi ingasetshenziswa isikhathi eside. Nokho, i-cyfluthrin (efana ne-cyfluthrin) inobuthi kakhulu futhi akufanele isetshenziswe isikhathi eside. Kodwa ukuqhathanisa okuqondile kobuthi phakathi kwe-cyfluthrin ne-furfuramide kusadinga ucwaningo olukhethekile ukuze kutholwe.

2. Mayelana nendlela yokwenza

I-Permethrin iphazamisa ngokuyinhloko isimiso se-neural conduction yezinambuzane, izivimbela ukuba zingahambi ngendlela evamile futhi ekugcineni zibangele ukufa kwazo. I-Furfuran isebenza ngokuphazamisa uhlelo lwe-metabolic yamaphela (ithatha amaphela njengesibonelo, indlela yayo yokusebenza ngokumelene nezinye izinambuzane iyafana), ivimbele ukuthi zingakhuli futhi zizalane ngokujwayelekile. Iphinde ibe nemiphumela emihle kakhulu yokulawula ezinambuzaneni ezibhobozayo ezincela umlomo futhi ibonise umsebenzi ophezulu wokubulala izinambuzane ngemithamo ephansi kakhulu.

3. Mayelana nezinhloso zokuvimbela nokulawula

I-Permethrin isetshenziswa kakhulu ukulawula izinambuzane ezinjengomiyane, izimpukane, amazeze nezintwala. Kwezolimo, ingalawula izinambuzane zezitshalo ezihlukahlukene. I-Fumefon isetshenziselwa kakhulu ukulawula ama-aphid, ama-leafhoppers, ama-planthopper kanye nezinye izinambuzane ezincelisayo ezitshalweni ezihlukahlukene. Iphinde ibe nomphumela omuhle wokulawula izinambuzane zasekhaya njengamaphela. Ngaphezu kwalokho, inomphumela ongcono kakhulu wokulawula ezinambuzaneni eziye zaqala ukumelana nama-agent e-nicotinoid.
