Manje ake sithole imininingwane mayelana nezinhlobo ezimbili zemithi yokubulala ukhula, okuyimithi yokubulala ukhula ekhethwayo nengakhethi. I-Herbicide uhlobo lwamakhemikhali abulala izitshalo ezingafuneki, ezivame ukubizwa ngokuthi ukhula. Izinto ezinjengokhula zingakhula ngokushesha okukhulu futhi zisakazeke ezindaweni esifuna izitshalo zethu ezinhle (izimbali, imifino) zibe yimbewu. Ngakho-ke kulapho imithi yokubulala ukhula iba amathuluzi awusizo asetshenziswa abalimi nabalimi.
Izibulala-zinambuzane ezikhethiwe zenzelwe ukusebenza ngokumelene nezitshalo ezithile kuphela. Bayakwazi ukubulala ukhula ngaphandle kokwenza umonakalo kuzo zonke izitshalo. Isibonelo, umuthi othile wokubulala ukhula uzobulala ukhula olunamaqabunga abanzi (olunamaqabunga abanzi) kodwa ngeke ubulale utshani (unamaqabunga amade namancane), lolu hlobo lubizwa ngokuthi ukukhetha. Lokhu kubazuzisa kakhulu abalimi noma abalimi njengoba kubasiza ekuqedeni ukhula oluhluphayo futhi bagcine izitshalo zabo ezinhle zingathinteki.
Bese kuba nemithi yokubulala ukhula engakhethi uma kufika isikhathi sokukhuluma ngokukhomba. Imithi enjalo yokubulala ukhula inamandla ngokwedlulele futhi izobhubhisa noma yiziphi izimila ezihlangana nazo. Isibonelo sesinye yi-glyphosate, ewumuthi wokubulala ukhula ohleliwe, ongakhethi ozobulala kokubili ukhula ofuna ukulususa kanye nanoma yiziphi izitshalo ofuna ukuzigcina ziphila. Lokho kungaba yingozi uma ungaqaphile uma uyisebenzisa ngoba izolimaza nezitshalo zakho ezinhle.
Izinzuzo eziningi, noma amaphuzu amahle, ama-herbicides akhethiwe. Inzuzo eyodwa enkulu ukuthi azivumelani nemvelo. Ngenxa yokuthi zikhomba kuphela izinhlobo ezithile zezitshalo, aziyona ingozi ezitshalweni nasezilwaneni esifuna ukuzivikela. Lokhu kusho ubungozi obuncane ezingadini nasemapulazini. Ngaphezu kwalokho, ezinye izinhlobo zokhula zingaba lula kakhulu emithini ekhethiwe yokubulala ukhula. Imithi yokubulala ukhula engakhethi (ebulala yonke into engadini yakho) ngezinye izikhathi ingaba yisixazululo esingcono, kodwa futhi, olunye ukhula luhlala lungalimele!
Ama-herbicide angakhethi afana ne-glyphosate aguquguquka kakhulu, ngokuthi, azobulala noma yisiphi isitshalo esithintana naye. Ayashesha, nokho, futhi angasusa uhlaza ngokushesha. Lokhu kusebenza ikakhulukazi emisebenzini emikhulu, njengokugawula amahlathi, noma amasimu amakhulu. Noma kunjalo, kufanele sicabangele ukuthi ziyingozi kakhulu emvelweni nasezindaweni ezizungezile zemvelo kanjalo nezindawo ezinjalo kufanele zisetshenziswe ngokucophelela okukhulu.
Ukukhethwa kwe-herbicide ekhethiwe noma engakhethi incike kulokho okudingayo ngempela. Ama-Herbicides akhethiwe - Uma inkinga incane ngezinhlobo ezimbalwa zokhula, umuthi okhethiwe ungaba yisixazululo sakho esingcono kakhulu. Izokuvumela ukuthi uqondise kuphela lolo khula ngaphandle kokulimaza izitshalo zakho ezinempilo. Nokho, uma ingadi yakho iyihlathi elikhulu lokhula khona-ke ungase ufune ukusebenzisa okuthile okungakhethi.
Lapha sikutshele ngezibulala-khula ezikhethiwe eziwusizo kakhulu kodwa ezinobubi/nobubi. Inkinga enkulu ngazo ukuthi zisebenza kuphela ezinhlotsheni ezithile zokhula. Kwezinye izimo, ukhula luyamelana nezigaba ezithile zokubulala ukhula. Manje uma ulandela umuthi wokubulala ukhula owodwa iminyaka esheshayo, lezi zinhlobo zokhula zizosala ziyimpande yazo, futhi ngokuzayo imikhiqizo eminingi yokudla izokhuphuka njengoba isetshenziswe ngaphandle kwethonya elincishisiwe elivela ekulimazeni kwakho kwemvelo.
