I-Deltamethrin
Incazelo Yomkhiqizo
I-Deltamethrin(ifomula ye-molecular C22H19Br2NO3, isisindo sefomula 505.24) iyikristalu emhlophe emise okwenqubomgomo etshekile enephuzu lokuncibilika elingu-101~102°C kanye nephuzu elibilayo elingu-300°C. Cishe ayincibiliki emanzini ekamelweni lokushisa futhi iyancibilika kuzincibilikisi eziningi eziphilayo. Izinzile ekukhanyeni nasemoyeni. Izinzile ku-acidic medium, kodwa ayizinzile endaweni ye-alkaline.
I-Deltamethrin iyisibulala-zinambuzane esiyingozi kakhulu se-pyrethroid. Inobuthi obuphindwe izikhathi eziyi-100 ezinambuzaneni njenge-DDT, buphindwe izikhathi ezingu-80 kune-carbaryl, izikhathi ezingu-550 kune-malathion, kanye nezingu-40 kune-parathion. Izikhathi. Inokubulala okuthintwayo kanye nomthelela wobuthi besisu, umphumela wokubulala ukuthintana okusheshayo, amandla aqinile wokuwisa, awukho umfucuza kanye nomphumela wesistimu, kanye nomthelela wokuxosha ezinye izinambuzane ezindaweni eziphezulu. Isikhathi eside (izinsuku eziyi-7-12). Yakhelwe ku-concentrate emulsifiable noma impushana emanzi, iyisibulala-zinambuzane esimaphakathi. Ine-spectrum ebanzi ye-insecticidal futhi iyasebenza ezinhlobonhlobo zezinambuzane ezifana ne-Lepidoptera, Orthoptera, Thysanoptera, Hemiptera, Diptera, Coleoptera, njll., kodwa inomphumela ophansi kakhulu wokulawula ngokumelene nezibungu, izinambuzane zesikali, nezimbungulu. Noma empeleni ayisebenzi, futhi izophinde ikhuthaze ukuzala kwezibungu. Uma izinambuzane nezibungu kuhambisana, kufanele kuhlanganiswe nama-acaricides akhethekile.
I-Deltamethrin ingeyesigaba sobuthi. Ukuthintana kwesikhumba kungabangela ukucasuka kanye nama-papules abomvu. Ngoshevu obunzima, izimo ezithambile zingase zibe nekhanda elibuhlungu, isiyezi, isicanucanu, ukuhlanza, ukuphelelwa ukudla, nokukhathala, futhi izimo ezimbi kakhulu zingase zibe nokunyakaziswa kwemisipha nokudlikizela. Inomphumela ovuselelayo esikhumbeni somuntu kanye nolwelwesi lwamafinyila lwamehlo, futhi inobuthi obukhulu ezinhlanzini nasezinyosini. Izinambuzane ezimelana ne-DDT azikwazi ukumelana ne-deltamethrin.
