Ndechipi zvipembenene zvinogona kudzorwa ne cypermethrin uye kuti zvingashandiswa sei?

Maitiro uye hunhu hwechiito

CypermethrinChinangwa chikuru ndechekuvhara nzira ye sodium ion mumasero etsinga dzezvipembenene, kuitira kuti masero etsinga atadze kushanda, zvichikonzera kuoma kwenhengo dzezvipembenene, kusashanda zvakanaka, uye pakupedzisira kufa. Mushonga uyu unopinda mumuviri wezvipembenene nekubata uye kunwa. Une simba rekubuda nekukurumidza uye unodzivirira chikafu.

Applkuiswa kwechando

1. Zvirimwa nenzvimbo dzinoshanda: Huni, machira, dzimba, maindasitiri, nzvimbo dzisiri dzekugadzira chikafu.

2. Kudzora zvipembenene zvehutsanana zvematanda nemachira, nhunzi, umhutu, mapete nezvimwe zvipembenene zvemhuri, hutano hweveruzhinji nemaindasitiri.

3. Chengeta zvasara uye zvakachengeteka zvinoshandiswa muimba inodziya zvishoma, yakaoma uye ine mhepo inofefetera zvakanaka, usazvisanganisa nechikafu nezvinhu zvinoshandiswa, uye usabvumira vana kuti vaswedere pedyo. Mushonga uyu hauna mushonga chaiwo, kana kuti zviratidzo zvekurapa chepfu.

Chigadzirwa ichi chine simba guru rekubata, chepfu mudumbu uye chinoshanda mukurwisa zvipembenene, chinokwanisa kudzora zvipembenene zvemumba, munzvimbo dzeveruzhinji, munzvimbo dzemaindasitiri nezvimwe zvipembenene zvine hutano. Chinoshanda zvakanyanya pakurwisa mapete (kunyanya mapete makuru, akadai sepete rine ruvara rweutsi, mapete ekuAmerica, nezvimwewo) uye chine simba guru rekudzinga.

Chigadzirwa ichi chinopfapfaidzwa mumba ne0.005% ~ 0.05% zvichiteerana, izvo zvine simba guru rekumhanyisa nhunzi dzemumba, uye kana huwandu hwacho hwadzikiswa kusvika pa0.0005% ~ 0.001%, chine simba rinokwezva. Kurapa kwemvere dzemakwai kunogona kudzora zvinobudirira bag moth, screen moth uye monochrome fur, uye kushanda kwacho kuri nani pane permethrin, fenvalerate, proparthrin uye d-permethrin. Ndiyo yega mushonga wezvipembenene wakatenderwa kushandiswa nendege muUnited States uye ndeimwe yemishonga yekuuraya zvipembenene inokurudzirwa neWorld Health Organisation. Ine hutachiona hwakakura hwezvipembenene, uye simba rayo rekuuraya zvipembenene rakapetwa ka8.5 kusvika makumi maviri kupfuura pyrethroids. Yakasimba kana yakareruka kupfuura propylene benzyl, asi haina simba rakaipa pazvipembenene. Nokudaro, inoda kusanganiswa nemishonga yekuuraya zvipembenene ine simba guru rekubvisa nhunzi senge amethrin neES-propylene, uye inogona kushandiswa zvakanyanya mukudzivirira zvipembenene mudzimba, mukuchengetedza, muhutano hweveruzhinji nenzvimbo dzemaindasitiri.
