Ngoku makhe sifumane iinkcukacha malunga neentlobo ezimbini zemichiza yokutshabalalisa ukhula, ezikhethiweyo nezingakhethiyo. I-Herbicide luhlobo lwekhemikhali ebulala izityalo ezingafunekiyo, ezibizwa ngokuba lukhula. Izinto ezifana nokhula zinokukhula ngokukhawuleza kwaye zisasazeke kwiindawo esifuna izityalo zethu ezilungileyo (iintyatyambo, imifuno) zibe nembewu. Ngoko ke kulapho imichiza yokutshabalalisa ukhula iba zizixhobo eziluncedo ezinokusetyenziswa ngamafama nabasebenzi bezitiya.
Imichiza yokutshabalalisa ukhula eyilelwe ukuba isebenze ngokuchasene nezityalo ezithile kuphela. Ziyakwazi ukubulala ukhula ngaphandle kokwenza umonakalo kuzo zonke izityalo. Umzekelo, umchiza othile wokutshabalalisa ukhula uya kubulala ukhula olunamagqabi abanzi (olunamagqabi abanzi) kodwa aluyi kubulala ingca (unamagqabi amade nacuthene), olu hlobo lubizwa ngokuba lukhetho. Oku kuluncedo kakhulu kumafama okanye abalimi njengoko kubanceda baphelise ukhula oluyinkathazo kwaye bagcine izityalo zabo ezilungileyo zingachaphazeleki.
Kukho ke imichiza yokutshabalalisa ukhula engakhethiyo xa kufika ixesha lokuthetha ngokujolisa. Imichiza yokutshabalalisa ukhula inamandla kakhulu kwaye iyakutshabalalisa nasiphi na isityalo esithe yadibana nayo. Umzekelo womnye yi-glyphosate, isichiza sokhula esingakhethiyo esisistim (systemic, non-elective herbicide) esiza kubulala zombini ukhula ofuna ukulususa kunye naziphi na izityalo ofuna ukuzigcina ziphila. Oko kunokuba yingozi ukuba awulumkanga xa uyisebenzisa kuba iya kwenzakalisa izityalo zakho ezintle.
Uninzi lweenzuzo, okanye amanqaku amahle, emichiza ekhethiweyo yokutshabalalisa ukhula. Enye inzuzo enkulu kukuba zinobuhlobo ngakumbi nokusingqongileyo. Kuba zijolise kuphela kwiintlobo ezithile zezityalo, aziyongozi kwizityalo nakwizilwanyana esifuna ukuzikhusela. Oku kuthetha umngcipheko omncinci kwiigadi kunye neefama. Ngaphezu koko, ezinye iindidi zokhula zinokuchanabeka kwimichiza yokutshabalalisa ukhula ekhethiweyo. Imichiza yokutshabalalisa ukhula engakhethiyo (ebulala yonke into egadini yakho) ngamanye amaxesha inokuba sisisombululo esingcono, kodwa ke kwakhona, olunye ukhula luhlala lungonzakali!
Imichiza yokhula engakhethiyo efana ne-glyphosate iyaguquguquka ngakumbi, kuba, iya kubulala nasiphi na isityalo esidibana nayo. Ziyakhawuleza, nangona kunjalo, kwaye ziyakwazi ukutshayela ngokukhawuleza uhlaza olupheleleyo. Oku kuluncedo kakhulu kwimisebenzi emikhulu, njengokugawula amahlathi, okanye amasimi amakhulu. Nangona kunjalo, kufuneka sithathele ingqalelo into yokuba ziyingozi kakhulu kwindalo nakwizilwanyana zasendle ezingqongileyo ngokunjalo ke ezo ndawo kufuneka zisetyenziswe ngononophelo olukhulu.
Ukukhetha imichiza yokutshabalalisa ukhula ekhethiweyo okanye engakhethiyo iphelela ekubeni yintoni kanye oyifunayo. I-Herbicides ekhethiweyo - Ukuba umcimbi umncinci kunye neentlobo ezimbalwa zokhula, umchiza okhethiweyo unokuba sisisombululo sakho. Kuya kukuvumela ukuba ujolise kuphela olo khula ngaphandle kokonakalisa izityalo zakho eziphilileyo. Nangona kunjalo, ukuba igadi yakho ilihlathi elikhulu lokhula ngoko unokufuna ukusebenzisa into engakhethiyo.
Apha sikuxelele imichiza yokutshabalalisa ukhula ekhethiweyo eluncedo kakhulu kodwa enokungalunganga / okubi. Ingxaki ephambili kubo ngokuqhelekileyo basebenza kuphela kwiintlobo ezithile zokhula. Kwezinye iimeko, ukhula lukhula luxhathisa kwiindidi ezithile zemichiza yokutshabalalisa ukhula. Ngoku ukuba ulandela umchiza wokutshabalalisa ukhula omnye kwiminyaka ephanyazayo, ezi ntlobo zokhula ziya kushiywa kwimo yazo yeengcambu, kwaye kwixesha elizayo malunga neemveliso ezininzi zokutya ziya kunyuka kanye njengoko zisetyenzisiwe ngaphandle kwempembelelo encitshisiweyo evela kwimifuno yakho yendalo eyonakalisayo.
