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.
Siyathanda ukuqhuba kwenye indawo yethu.
