Uhlelo olusha lokulethwa kwemithi yokubulala ukhula lungaguqula indlela abaphathi bezolimo nemvelo abalwa ngayo nokhula oluhlaselayo.
Indlela ehlakaniphile isebenzisa amaphilisi agcwaliswe ngokhula abhobolwe eziqwini zokhula oluhlaselayo futhi iphephile, ihlanzekile futhi isebenza kahle njengezifutho zokubulala ukhula, okungaba nomthelela omubi empilweni kubasebenzi nasezindaweni ezizungezile.
U-Amelia Limbongan owenza iziqu ze-PhD ovela eNyuvesi yaseQueensland's School of Agriculture and Food Sciences uthe le ndlela iphumelela kakhulu ezinhlobonhlobo zezinhlobo zokhula, ezibeka engcupheni enkulu izinhlelo zokulima namadlelo.
“Ukhula olunemithi efana neMimosa bush luvimbela ukukhula kwamadlelo, luthiya ukuqoqwa futhi ludale umonakalo enyameni nasemalini ezilwaneni nasezimpahleni,” kusho uNksz Limbongan.
“Le ndlela yokulawula ukhula iyasebenza, iyaphatheka futhi iwusizo kakhulu kunezinye izindlela futhi sesibone ochwepheshe abaningana nemikhandlu besebenzisa le ndlela.”
Ukuphatheka kanye nokuba lula kwesistimu, kuhambisana nokusebenza kwayo okuqinisekisiwe nokuphepha, kwakusho ukuthi umuthi wokubulala ukhula ofakiwe ungasetshenziswa kuzilungiselelo nezindawo ezahlukahlukene emhlabeni jikelele.
“Le ndlela isebenzisa i-herbicide encishisiwe ngamaphesenti angama-30 ukubulala ukhula, futhi iyasebenza njengezindlela ezidinga abasebenzi abaningi, ezizokonga isikhathi esibalulekile nemali kubalimi nakubasebenzi bamahlathi,” kusho uNksz Limbongan.
“Kungase futhi kuholele ekuphathweni kangcono kokhula ezinhlelweni zezolimo nezemvelo emhlabeni wonke, kuyilapho futhi kuvikela abasebenzi ngokuqeda ukuchayeka kwabo emithini yokubulala ukhula eyingozi.
“Kunemakethe enkulu yalobu buchwepheshe emazweni lapho ukhula oluhlaselayo luyinkinga nalapho amahlathi kuyimboni, okungaba cishe wonke amazwe.”
USolwazi uVictor Galea uthe lolu hlelo lwasebenzisa isifakeli esisebenza ngomshini esibizwa nge-InJecta, esisheshe sabhoboza imbobo esiqwini sokhula, safaka i-capsule encibilikayo enomuthi wokubulala ukhula owomile futhi yavala i-capsule esiqwini ngepulaki yokhuni, yadlula isidingo. ukufafaza ezindaweni ezinkulu zomhlaba.
“Umuthi wokubulala ukhula ube usuncibilikiswa yincindi yezitshalo bese ubulala ukhula ngaphakathi futhi, ngenxa yomthamo omncane wokubulala ukhula osetshenziswa ku-capsule ngayinye, awubangeli ukuvuza,” kusho uSolwazi Galea.
“Esinye isizathu esenza lolu hlelo lokudiliva lube wusizo kakhulu ukuthi luvikela izitshalo ezingahlosiwe, ezivame ukulimala ngokuthintana ngephutha uma kusetshenziswa izindlela zesintu ezifana nokufutha.”
Abacwaningi basaqhubeka nokuvivinya indlela ye-capsule ezinhlotsheni zokhula eziningana futhi banenani lemikhiqizo efanayo emgqeni wokusatshalaliswa, okuzosiza abalimi, amahlathi nabaphathi bezemvelo baqede ukhula oluhlaselayo.
“Omunye wemikhiqizo ehlolwe kuleli phepha locwaningo, i-Di-Bak G (glyphosate), isivele idayiswa e-Australia kanye nemishini yokufaka isicelo futhi ingathengwa ngezitolo zezolimo ezweni lonke,” kusho uSolwazi Galea.
"Eminye imikhiqizo emithathu ilungiselelwa ukubhaliswa futhi sihlela ukunweba lolu hlobo ngokuhamba kwesikhathi."
