Deltamethrin

Ingcaciso yeMveliso

Deltamethrin(i-molecular formula C22H19Br2NO3, i-formula weight 505.24) yikristale emhlophe ye-oblique efana ne-oblique ene-melting point ye-101 ~ 102 ° C kunye nendawo yokubilisa ye-300 ° C. Iphantse inganyibiliki emanzini kwiqondo lobushushu begumbi kwaye inyibilika kwizinyibilikisi ezininzi zezinto eziphilayo. Izinzile ekukhanyeni nasemoyeni. Izinzile ngakumbi kwi-acidic medium, kodwa ayizinzanga kwi-alkaline medium.

I-Deltamethrin yeyona tyhefu yezinambuzane zepyrethroid. Iyityhefu ngamaxesha ali-100 kwizinambuzane njenge-DDT, ngokuphindwe ngama-80 kune-carbaryl, ngokuphindwe ngama-550 kune-malathion, kunye nama-40 njenge-parathion. Amaxesha. Inokubulala ukudibana kunye nesiphumo setyhefu yesisu, isiphumo esikhawulezayo sokubulala, amandla okubetha anamandla, akukho qhumiso kunye nesiphumo senkqubo, kunye nesiphumo sokugxotha kwezinye izitshabalalisi kwindawo ephezulu. Ixesha elide (i-7 ~ 12 iintsuku). Yenziwe ibe yi-emulsifiable concentrate okanye umgubo omanzi, sisibulali zinambuzane esiphakathi. Inoluhlu olubanzi lwezinambuzane kwaye iyasebenza ngokuchasene neentlobo zezinambuzane ezifana neLepidoptera, i-Orthoptera, i-Thysanoptera, i-Hemiptera, i-Diptera, i-Coleoptera, njl., kodwa inefuthe eliphantsi kakhulu lokulawula ukulwa namangolwane, izinambuzane zesikali, kunye nezinambuzane. Okanye ayisebenzi, kwaye iya kuvuselela ukuzala kwamangolwane. Xa izinambuzane kunye namangolwane zidibene, kufuneka zixutywe ne-acaricides ekhethekileyo.

I-Deltamethrin yeyodidi lwetyhefu. Uqhagamshelwano lwesikhumba lunokubangela ukucaphuka kunye neepapules ezibomvu. Kwityhefu ebukhali, iimeko ezithambileyo zinokuba nentloko, isiyezi, isicaphucaphu, ukuhlanza, ukulahlekelwa ngumdla wokutya, kunye nokudinwa, kunye neemeko ezinzima zinokuba ne-muscle fasciculations kunye nokuxhuzula. Inefuthe elikhuthazayo eluswini lomntu kunye ne-eye mucous membranes, kwaye inetyhefu kakhulu kwiintlanzi nakwiinyosi. Izinambuzane ezikwaziyo ukumelana ne-DDT ziyakwazi ukumelana ne-deltamethrin.
