I-Mancozeb, isibulala-sikhunta esiyisivikelo esisetshenziswa kakhulu ekukhiqizweni kwezolimo, izuze isihloko esiphawulekayo esithi “Inkosi Yokubulala Nzalo” ngenxa yokusebenza kwayo okuphezulu uma kuqhathaniswa nezinye izibulala-sikhunta zohlobo olufanayo. Ngekhono layo lokuvikela nokuvikela ezifweni zesikhunta ezitshalweni, le mpushana emhlophe emhlophe noma ekhanyayo isiphenduke ithuluzi eliyigugu kubalimi emhlabeni wonke.
Esinye sezici eziyinhloko ze-mancozeb ukuzinza kwayo. Ayincibiliki emanzini futhi ibola kancane ngaphansi kwezimo ezinzima njengokukhanya okukhulu, umswakama, nokushisa. Ngakho-ke, igcinwa kangcono endaweni epholile neyomile, iqinisekisa ukusebenza kwayo okuhle kakhulu. Nakuba i-mancozeb iyisibulala-zinambuzane esine-asidi, kufanele kuqashelwe lapho ihlanganiswa namalungiselelo anethusi ne-mercury noma ama-alkaline. Ukusebenzisana phakathi kwalezi zinto kungaholela ekwakhekeni kwegesi ye-carbon disulfide, okuholela ekwehleni kokusebenza kwesibulala-zinambuzane. Ngaphezu kwalokho, nakuba i-mancozeb inobuthi obuncane uma kuqhathaniswa, yenza izinga elithile lokulimala ezilwaneni zasemanzini. Ukusetshenziswa ngendlela efanele kubandakanya ukugwema ukungcoliswa komthombo wamanzi nokulahlwa ngendlela efanele kwamaphakheji namabhodlela angenalutho.
I-Mancozeb itholakala ngezinhlobo ezahlukene, okuhlanganisa impushana emanzi, i-suspension concentrate, ne-water dispersible granule. Ukuhambisana kwayo okuhle kakhulu kwenza ikwazi ukuxutshwa namanye ama-systemic fungicides, okuholela efomini lomthamo elinezingxenye ezimbili. Lokhu akugcini nje ngokuthuthukisa ukusebenza kwayo kodwa futhi kubambezela ukukhula kokungazweli emishanguzweni ngokumelene nama-systemic fungicides.MI-ancozeb ngokuyinhloko isebenza phezu kwezitshalo, ivimbele ukuphefumula kwezinhlamvu zesikhunta futhi ivimbele ukuhlasela okwengeziwe. Ingafaniswa nesici “sokuvimbela” sokulawulwa kwezifo ezikhunta.
Ukusetshenziswa kwe-mancozeb kuye kwashintsha ukukhiqizwa kwezolimo ngokunikeza abalimi ithuluzi elisebenza kahle kakhulu lokulwa nezifo zokukhunta ezitshalweni zabo. Ukuguquguquka kwayo nokuhambisana kwayo kuyenza ibe yimpahla ebalulekile ezinqolobaneni zabalimi. Ukwengeza, imvelo yayo yokuvikela iqinisekisa inhlalakahle yezitshalo, izivikele emiphumeleni eyingozi yama-pathogens fungal.
Sengiphetha, i-mancozeb, “Inkosi Yokuvala Inzalo,” isewumuthi ovikelayo othembekile nonokwethenjelwa kwezolimo. Ukusebenza kwayo okuvelele, isimo esizinzile, kanye nokuhambisana nezinye izibulala-fungi zesistimu kwenza kube ithuba lokuzikhethela kubalimi abafuna izixazululo ezibanzi zokulawula izifo. Ngokusetshenziswa ngendlela efanele nokugcinwa ngendlela efanele, i-mancozeb iyaqhubeka nokubamba iqhaza elibalulekile ekuvikeleni impilo yezitshalo nasekukhuliseni umkhiqizo wezolimo.
