Ikhemikhali eyaziwa ngokuthi isilawuli sokukhula kwezitshalo ekhona manje esisetshenziswa kakhulu abalimi ensimini ukulwa nalolu hlobo lokhula. Ukhula yizivakashi ezingamenyiwe ezimila phakathi kwezitshalo zintshontsha imisoco edingekayo, amanzi nokukhanya kwelanga ngaleyo ndlela zingabi nempilo enhle. I-Clodinafop propargyl iwumuthi wokubulala ukhula ngemuva kokuvela. Umuthi wokubulala ukhula uyikhemikhali esebenza ukucekela phansi lezi zitshalo, njengokhula ukuze abalimi bakwazi ukukhiqiza ukudla okwengeziwe.
I-Clodinafop propargyl inhle kakhulu ukusetshenziswa emaqenjini athile okhula. Ivimbela umsebenzi oyingqayizivele wesitshalo ngaphakathi kokhula, yingakho abalimi besebenzisa lesi sibulala-khula. Ibhithi elisebenzayo liyi-enzyme futhi lapho i-clodinafop propargyl ivimbela lesi sigaba, ukhula alukwazi ukuthuthuka futhi lufe. Lo muthi wokubulala ukhula uyathandwa abalimi ngoba ubulala ukhula ngemva kokuba selumile ensimini efanayo nezitshalo zabo. Ukuqaphela, lokhu kusho ukuthi abalimi akudingeki bakhathazeke kakhulu mayelana nesikhathi esiqondile sokuthi uzowusebenzisa nini umuthi wokubulala ukhula ngokwawo. Bangakwazi ukulawula ukhula lapho bethinta, ngakho kuba lula ukugcina izindawo zabo zihlanzekile.
Ingxube yamakhemikhali ahlukahlukene asebenza njenge-Clodinafop propargyl. Ingxenye ye-propargyl iyingxenye ebalulekile yayo. Kubalulekile ukuvimbela i-enzyme ekhuthaza ukukhula kokhula ekusebenzeni. UMichaud uthi ukwazi ukwakheka komuthi wokubulala ukhula kuwulwazi oluwusizo kubalimi ukuze baqonde ukuthi usebenza kanjani kanye nokusetshenziswa kwawo ngendlela efanele ensimini. Ngokwazi izingxenye, abalimi bangenza izinqumo ezinolwazi mayelana nezindlela zokuzisebenzisa ekulawuleni ukhula.
Nokho, lokhu ngezinye izikhathi kwenzeka bengahlosile lapho abalimi besebenzisa imithi yokubulala ukhula efana i-glyphosate herbicide ekulawuleni ukhula ngoba kulimaza nezitshalo abangahlosile ukuzibulala. Izitshalo ezisengcupheni yokulimala zaziwa ngokuthi izitshalo ezingahlosiwe. Abalimi kufanele baqaphele futhi bacabangele ukuthi yiziphi izitshalo ezingase zihlangane nazo ngesikhathi sokusebenzisa le khemikhali. I-Clodinafop propargyl ingase isebenze kakhulu kobunye utshani kunobunye. Lokhu kusho ukuthi kungase kuqede ngephutha utshani abalimi abafuna ukubusindisa njengalezo izilwane ezidla utshani ezithembele kubo noma obunezimpande ezijulile okusiza ukuvimbela ukuguguleka nokugcina ukungcola kunempilo.
Ngesikhathi esifanayo, ukusetshenziswa kwezibulala-khula ezifana ne-clodinafop propargyl kungaba nomthelela emaqenjini emvelo. Zonke izakhi ezingaphakathi kwala makhemikhali, ngesikhathi eqala ukuwasebenzisa, zikhukhuleka zibe yinhlabathi, emanzini nasemoyeni. Kuthinta izilwane nezitshalo ezingafuneki, okungafanele ukuthi zitholwe wumuthi wokubulala ukhula. Abalimi kufanele bayicabangele le miphumela uma betshala ukudla kwabo ukuze baqinisekise ukuthi ukudla kuzotshalwa ngendlela ehambisana nemvelo.
Abalimi banezinketho ezimbili uma kuziwa emithini yokubulala ukhula, bangasebenzisa imithi yokubulala ukhula ngaphambi kokuhluma noma emva kokuhluma. Ama-pre-emergence herbicides asetshenziswa ngaphambi kwesigaba sokuhluma kwezitshalo. Kuyasiza futhi ukuvimbela ukhula ekukhuleni nezitshalo. Ngokuphambene, ama-herbicides angemuva kokuvela njenge-clodinafop propargyl asetshenziswa ngemuva kokuvela kwezitshalo. Lokhu kubalulekile ngoba i-clodinafop propargyl iphumelela ngokuphawulekayo ekucekeleni phansi ukhula lwasensimini olukhona.
I-CIE Chemical iyakwazi futhi ukuqwashisa abalimi ngomuthi wokubulala ukhula, ngendlela yawo yokusebenza kanye nendlela engcono yokuwusebenzisa ngayo. Ngemfundo, abalimi bangathola isiqondiso sokuthi bangawusebenzisa kanjani ngokuphephile lo kubulala ukhula ukuze usebenze ngaphandle kokulimaza izitshalo noma amachibi. I-CIE Chemical inikeza lolu lwazi ukuze kuqinisekiswe ukuthi i-clodinafop propargyl isetshenziswa ngempumelelo nangokuzibophezela.
