Iindlela zokusebenzisa Amaphetha Okugcwaliswa
Amaphetha okugcwaliswa azifunyanwa ngokubheka nokuthi bavakasha umsebenzi wendawo yobukheli besiqephu somdlalo. Indawo yobukheli ifuna ukuba kuhluke kakhulu chlorpyrifos kwiqinisekiso, ukudla, kunye nomkhankaso kwesiqephu. Okuningi lokulandelana nendawo yobukheli kunjalo kukho ukuze lento yisithintelo yokugcwaliswa. Ngokwesobizo, amanani angaphezulu cypermethrin azigcwaliswa isiqephu namandla ngokuphi imibuzo ezikhoyo. Kuneenani elingangamphetha olungaphezulu elizigcwaliswa esingayiphi uhambo lwemfino wegrass ukulayisha, ngakho kokufuneka ukusuka kwezintshangiso. Oko kungabangako ukuthi kube ngenqanawe yezintshangiso ngokubanjwa ukuba zingatengelana ngemibuyelo, ukuphatha noma ukugcwalisa izandla. Ukuthi inguqule kuninzi okanye i-INSECTICIDE ifanele lingaphandle kwi- TYPE yezinto ezilayishayo, umthetho wokuvelisela kunye nomncedo weveliselo.
Amaklayasi Akhulu Kwezinselezo Zentshangiso Nge Sinye Sobalulekile
Kuneenkcwadi zakwangaphakathi ezikhoyo zezintshangiso ezifumanekayo, apho okunye inikezwa ukukusetshenziswa ukusuka kumahluko angaphezulu kwabantu abayaziwa:
Ama-Pyrethroids: Izintshangiso eziningi zikwentsha amafu amahhamsantamu (chrysanthemums) futhi zihlabeleka kakhulu emibhalweni eyendlaweni. Zisetshenziswa ngokusebenzisa isistimu sasendlela sokuziphambili kwezinyanya zeziqephu, uzoba zaziphuma ngaphandle kokufika noma ukusetshenziswa ngokuphi ndawonye.
Neonicotinoids: Oko kuhluke izintshangiso ezidingekayo, ukuze zisebenzise ukuthi zizivamiswe emandla kaqhawe lomphoyiso nokuthi zithunyelwe ngaphakathi komphoyiso wesitshalo. Zikhona ngokushaya ukuthi ziyiqhuba kakhulu kubantu abayaziwa ukuthi baziphumela amahluku apha esebenzisa amanzi esitshalweni, njenge-aphids, whiteflies kunye neleafhoppers.
