Njengoba isidingo sama-fungicides akhethekile sikhula, isidingo se-mancozeb kulindeleke ukuthi sikhule eminyakeni embalwa ezayo.Ama-insecticide (njenge-manganese, i-manganese, i-zinc) aqala ukusebenza kuphela lapho ehlangana nezingxenye ezihlosiwe zezitshalo zemifino nezithelo, izitshalo zokuhlobisa kanye ne-turf.Njengoba ezolimo ziwumgogodla weminotho ethile esafufusa nathuthukile, ukusongelwa izitshalo nezitshalo kungase kwenze buthaka umthombo oyinhloko wemali engenayo yabantu abaningi.Ngakho-ke, izinkinga ezihlobene nesikhunta nezinambuzane kufanele zixazululwe.
Ngenxa yezinto ezifana nokungakhethi nokusebenza ngempumelelo, isidingo se-mancozeb siphezulu uma siqhathaniswa nanoma yimuphi omunye umkhiqizo, futhi intengo iphansi.Ngaphezu kwalokho, uma kuqhathaniswa namanye ama-fungicides angakhethi emakethe, i-Mancob nayo ayizweli kancane.Isifunda sase-Asia-Pacific kulindeleke ukuthi sibe umthengi omkhulu we-mancozeb ngoba iyikhaya lamazwe amaningana asafufusa umnotho wawo uthembele kakhulu kwezolimo.Ukwenyuka kwengozi yokwehluleka kwezitshalo kuphinde kwabangela ukusetshenziswa komhlaba wonke kwe-mancozeb.
Abadlali be-Cream abasebenza emakethe ye-mancozeb yomhlaba wonke bagxile kumasu okuthengisa asebenzayo okwandisa isisekelo samakhasimende abo.Ezinye zalezi zinqubo zihlanganisa ucwaningo nokuthuthukiswa kwemikhiqizo engcono nethuthuke kakhulu kanye nokutholwa, ukuhlanganiswa nezinye izivumelwano ukuze zihlale zinokuncintisana emakethe yomhlaba.Kodwa-ke, ngenxa yokuvikelwa kwesikhunta, izinqubo zebhayoloji nezemvelo zingathiya ukuthuthukiswa kwemakethe kamango yomhlaba wonke.
Njengoba igama libonisa, iMancozeb iyisibulala-sikhunta esihlanganisiwe esenziwe nge-maneb (maneb) ne-zinc (zineb).Ingxube yala maqembu amabili asebenzayo enza lesi sibulali sikhunta sisetshenziswe kabanzi ezitshalweni ezahlukene.Indlela yokwenza ye-mancozeb fungicides ayiyona into ehlelekile, ivikela amasayithi amaningi, futhi isebenza kuphela lapho ihlangana nesitshalo esiqondiwe.Uma isibulala-sikhunta sihlasela amasayithi amaningi kumaseli esikhunta, sizokwenza ama-amino acid nama-enzyme amaningana okukhula, kuphazamise imisebenzi efana nokuphefumula, i-lipid metabolism, kanye nokukhiqiza kabusha.
I-Broad-spectrum fungicides ingasetshenziswa njengendlela yokwelapha ezimele yokulawula izifo zesikhunta emifino ehlukahlukene, izithelo, izitshalo namantongomane, njengamabala amaqabunga, i-anthracnose, i-downy mildew, ukubola nokugqwala.Isibulali sikhunta singasetshenziswa futhi sihlanganiswe namanye ama-fungicide ambalwa ukuze kuzuzwe imiphumela ekhethekile futhi engcono yokulawula izifo.
