Izifundo zomphumela zikhulu zinamva ngazo ezindabeni nezindlu zegardini ukuthola amadoda omphunyiswa. Izifundo zakho zihlukile kakhulu ngasemva sisondolozo esebenzisa kakhulu khona phambi kokuthi kuhlelwe imiphumulo yezisekelo. Ukungakho ngeendaba ezidingekayo zingavumelekanga ngaphandle komphumela olungapheli okusebenza lokuthi kuneendodakazi ezinjalo ezibhekene nesinye sinethelo.
Izindlela Zazo Zikhululeka: Izinyathelo zompyrethroid zikhululeka ngokubhekisisa umsebenzi wemibuzo yezintshangazi. Ngokuqaphela, leziphi zintshangazi zihlala ukuthiwelelwa ukusuka kubo (izimyane, iziflayi nezianti njengesibonelo). Zingasetyenziswa ngabahloki basekhaya kunye nembalase kuqinisekisa amandla okungakuhloniphe umdlalo wesintsi wokugcina nokukhupha ngokwesigodlo esebenza lokhu ngoba ayiqondisiyo labantu nokubafileyo. Lokhu kulula kokwesona kukho iminyaka engamashumi amabili lapho zisetshenziswa ukuqinisekisa amanye amacala ekhaya kunye nemibhalo yobunxele.
Izinyathelo zompyrethroid zisetyenziswa ngokusebenzisa isicatshululo esixhaswe pyrethrum. Lephyrethrum lisetyenziswa kwiiflowa ezininzi zechrysanthemum, ezazisetshenziswa kufundiswa ukubuka amacala namanye amaxesha. Abantu babhenzelela (ngokushesha) ngokubuyiselana nendawo yakhe, futhi bavumelela amaxwebhu omnyama we-pyrethroids osetyenziswa manje kwiinkomo. Lokhu kuvumelana nokuba bayayityenziswa ngokubheka ukusetshenziswa kwiincwadi yokuthiwelela ukusuka kwabo abantu ukuthola amacala nokuhlola ukuba kuhlanganise.
Ngokugqibela, iipirethroidi zingavumele kumntu noonke amakhulu, kodwa bayingayazi ukuba zizikhululekile endaweni yezilimo uma zingasetyenziswa ngokubona. Kufunekuhle ukuze ushaya amakhemikali oku kwiilayili noma amahluwana nokuba uzoba uzihlala izinkozo ezintsha neenkonzo eziphumayo emazibenini. Ngakho, abasebenzisi bezilima nobusekiso babizwe ukuba bazityenziswa kwisebe lokuhlola kwezi zinto. Ngoko ke, bazokwazi ukusurela ukuba ngokusetshenziswa kwezi khemikali, ukufaka kwabo kuthathwe ngokukholelwa kunye nokuba kube ngaphandle kokuphela komphilo wesistimu.
Lolu cwaningo, liphatha phakathi kweendlela ezimbini ezinomsindo yokugcina imibuzo ngoba iipirethroidi zifundza ukwenza ukucima amaxhonya ngqo ngqukukeneyo ukusetshenziswa kwezi khemikali ezikhulu ezikhululekileyo. Uma zisetyenziswa ngokubona, zingabuyiselwa ukuba ziyisebenzise ukwenzela ukuya kuwo abasebenzisi beelima ukwenza ukuphucula imibala engaphantsi njengamanzi kunye nokuthi akukho inani lemfuthe. Ngokushesha, xa isiphumo sasemva sihlala kakhulu kunye nokufuna imifuthe.
Sisinda isebenza esikhulu kwi-pyrethroids zethu kuzo zonke iinkimbinkimbi zokuhlanzeka njengekuphatha izilwane zokugqiba. Lokhu kufikwa ngokudibanisa ukwazi okukhulu ngendlela yokuqonda indlela yokusebenza yabo, nokunika iziphumo ezihle kwaye ukuba nezizathu zokuphatha izilwane zokugqiba. Isilinganiso sesithembiso sithi sisebenza phakathi kweminyaka engama-26, sibiza ingqesho yethu eyi-10,000 tons ngonyaka. Abantu abangama-60 kwaye abanentshukumo ziyakulandela ukubambisana nabasebenzi ukunika izinto ezipheleleyo neziservisi ezihle kwindlela yokuqonda.
Ronch ina-pyrethroids kwindlela yokuqiniseka kokuhlanzeka kwezindawo zombili. Ina-maqhaza amakhulu kwindlela yokuqamba abasebenzi. Ngokusebenza ngokuvutha kwaye ngokuzimela, ngokusebenzisa iziservisi ezihle kwaye izinto ezihle kakhulu, le ndawo iyakwakha ubukhulu bakho kumanyathelo amaninzi, ibeka igama lakho eliqinisekile kwindlela yokuqonda, kwaye isinike iziservisi ezihle kakhulu kwindlela yokuqonda.
i-pyrethroids inika iziphumo eziningi zokusebenza kumaziprojekthi. Lezi zikhuluma zonke iindawo zokuchitha amagqabi, ukuchitha amagqabi ngokupheleleyo, njengoko kunye nezinto eziNe (4) eziphambili, nezifomiletha ezahlukeneyo kunye nezintlobo zezixhobo ezinokusebenza ngazo zonke iintlobo zezixhobo. Zonke iimpahla zikwi-liste yezimpahla eziyayitholakala ngokuthembekileyo ngaphandle kwe-World Health Organization. Zisetyenziswa ngokubanzi kumaprojekthi njengekukhulula i-mosquitoes, i-flies, i-ants, i-termites, kunye ne-red fire ants, njengoko kunye nokuphatha ubomi bokuphila kwezwe nokuphatha iinkunzi.
i-pyrethroids iyathembisa ukuba yibe yinkundla yasezindaweni zokuphatha imithombo yomhlaba. Ngokusebenzisa umkhosi wasezweni wonke, kuthandakanya ngokufanayo imiphumela yezindawo zokusebenza nezindawo zokusebenzisa ngokuvamile, kusukela kubuxoki bokugcina ubuxoki bomthwalo wezilwanyana nesikhundla, nokusebenzisa ukuziphatha kwezinye izinto ezinokuthanda ukuzibophelela, ukuphinda ukuphendula ngokukhawuleza ubuxoki bokugcina okuchangalala kwebizinesi kwaye ukubabeka iimpilo eziphambili, ezipheleleyo, ezingenakukhathaza, nezinto zokuphatha imithombo yomhlaba, iindlela zokuchitha amakhungu kwaye iintlobo zokuchitha amakhungu zokuphatha imithombo yomhlaba.
Siyathanda ukuqhuba kwenye indawo yethu.
