U-anyanisi, ujinja, nesweli kuyizithako ezidingekayo ekuphekeni nasekuphekeni ezinkulungwaneni zemizi.Uma kunezinkinga zokuphepha kokudla ngezithako ezisetshenziswa nsuku zonke, izwe lonke lizotatazela ngempela.Muva nje, iumnyango wokuqondisa izimakethebathole uhlobo “lwe-chives olushintshe umbala” ngesikhathi sokuhlolwa okungahleliwe kwemakethe yemifino e-Guizhou.Lawa ma-chive ayathengiswa, futhi uma uwahlikihla kahle ngezandla zakho, izandla zakho zizoba nombala oluhlaza okwesibhakabhaka okhanyayo.
Kungani ama-chives ekuqaleni aluhlaza aphenduka abe luhlaza okwesibhakabhaka uma ekhuhliwe?Ngokwemiphumela yophenyo emenyezelwe iziphathimandla zendawo ezilawulayo, isizathu sokushintshwa kombala kwe-chives kungenzeka kungenxa yesibulala-zinambuzane "ingxube yeBordeaux" efuthwe abalimi ngesikhathi sokutshala.
Kuyini "Bordeaux liquid"?
Ukuxuba i-copper sulfate, i-quicklime namanzi ngesilinganiso esingu-1:1:100 kuzokwakha “i-sky blue colloidal suspension”, “okuyingxube ye-Bordeaux”
Isetshenziselwani "i-Bordeaux liquid"?
Ku-chives, uketshezi lwe-Bordeaux empeleni luyisibulala-sikhunta esisebenzayo futhi “lungabulala” amagciwane ahlukahlukene.Ngemuva kokuthi ingxube ye-Bordeaux ifafazwe phezu kwezitshalo, izokwakha ifilimu evikelayo engancibiliki kalula lapho evezwe emanzini.Ama-ion ethusi efilimu evikelayo angadlala indima ekubulaleni inzalo, izifoukuvimbela nokulondolozwa.
Ingabe i-"Bordeaux liquid" inobuthi obungakanani?
Izithako eziyinhloko ze-"Bordeaux liquid" zihlanganisa i-lime e-hydrated, i-copper sulfate namanzi.Umthombo oyinhloko wezingozi zokuphepha ama-ion ethusi.I-Copper iyinsimbi esindayo, kodwa ayinabo ubuthi noma ukunqwabelana kobuthi.Ingenye yezinto ezibalulekile zensimbi emzimbeni womuntu.Abantu abajwayelekile badinga ukudla okungu-2-3 mg ngosuku.IKomidi Lochwepheshe Lezithako Zokudla (JECFA)ngaphansi kwe-WHO ikholelwa ukuthi, ukuthatha umuntu omdala we-60-kg njengesibonelo, ukudla isikhathi eside kwansuku zonke kwe-30 mg yethusi ngeke kube usongo empilweni yomuntu.Ngakho-ke, "i-Bordeaux liquid" nayo ibhekwa njengesibulala-zinambuzane esiphephile.
Yimiphi imikhawulo yokulawula ye-"Bordeaux Liquid"?
Ngenxa yokuthi ithusi liphephile uma kuqhathaniswa, amazwe emhlabeni wonke awakayichazi ngokucacile imingcele yalo ekudleni.izindinganiso zikazwelonke zezwe lami zake zabeka ukuthi inani lethusi elisele ekudleni akufanele lidlule ku-10 mg/kg, kodwa lo mkhawulo waphinde wakhanselwa ngo-2010.
Uma izimo zivuma, kutuswa ukuthi uthenge eziteshini ezivamile ezifana nezitolo ezinkulu nezimakethe ezinkulu zabalimi, uzicwilise kahle ngaphambi kokudla ukuze ukhiphe izinsalela zezibulala-zinambuzane ezincibilika emanzini, bese ugeza ngokucophelela amaqabunga ka-anyanisi neziqu nezikhala ukuze uzisuse ” Izinsalela zezibulala-zinambuzane ezingancibiliki emanzini njenge-“Bordeaux Liquid” zingathuthukisa ngempumelelo ukuphepha kwama-chives noma ezinye izithelo nemifino.
