Imarike yemichiza yokutshabalalisa ukhula ibone ukunyuka kwenani kutsha nje, kunye nemfuno yaphesheya yemveliso yezobugcisa ye-glyphosate inyuka ngokukhawuleza. Oku kunyuka kwemfuno kukhokelele ekwehleni kwamaxabiso, okwenza ukuba umchiza wokutshabalalisa ukhula ufikeleleke ngakumbi kwiimarike ezahlukeneyo kuMzantsi-mpuma weAsia, eAfrika, nakuMbindi Mpuma.

Nangona kunjalo, kunye namanqanaba e-inventory eMzantsi Melika asephezulu, ugxininiso luye lwatshintshela ekuzaliseni kwakhona, kunye nokonyuka kwengqwalasela evela kubathengi kulindeleke kungekudala. Ukhuphiswano phakathi kweemarike zasekhaya nezangaphandle kwiimveliso ezifana ne-glufosinate-ammonium TC, glufosinate-ammonium TC, kunye ne-diquat TC nayo iye yaqina. Ukuphumelela kweendleko zesiphelo ngoku yeyona nto ibalulekileyo kwintengiselwano yezi mveliso, nto leyo eyenza ukuba kubaluleke kakhulu kwiinkampani ukugcina iindleko zazo zifanelekile.

Njengoko imichiza yokutshabalalisa ukhula isiya ifunwa kakhulu, unikezelo lwezinye iindidi luye lwaba luqilima, nto leyo ebeka uxinzelelo kwiinkampani ukuba ziqinisekise ukuba zinemfuyo eyaneleyo yokhuseleko ukuhlangabezana nemfuno.

Ikamva lemarike yemichiza yokutshabalalisa ukhula kwihlabathi liphela lijongeka linethemba njengoko ukwanda kwemfuno yemichiza yokutshabalalisa ukhula kuqhubeka nokukhula ngenxa yokwanda kwamasimi kunye nemveliso yokutya. Iinkampani ezikwimarike yemichiza yokutshabalalisa ukhula kufuneka zihlale zikhuphisana ngokunika izisombululo ezintsha kunye nokugcina amaxabiso afanelekileyo ukuze ahlale efanelekile kwimarike.

Ngaphandle kokungaqiniseki kwezoqoqosho ngoku, imarike ye-herbicide ibonakala iphumelele isaqhwithi kwaye ilungele ukukhula kwiminyaka ezayo. Iinkampani ezinokuhlangabezana neemfuno zeemakethi zasekhaya nezangaphandle ngokunikezela ngemichiza yokutshabalalisa ukhula ngendlela engabizi kakhulu, esemgangathweni ikwindawo entle yokuphumelela kwimarike yehlabathi yemichiza yokutshabalalisa ukhula.
