Universal kusho ukulawula ukhula "Roundup": yokusetshenziswa

Umuthi 'Roundup' ukufundisa ukusetshenziswa uchaza njengendlela yokuthola jikelele eziklanyelwe ukubhujiswa ukhula. Namuhla-ke ingenye yokubulala ukhula kakhulu owaziwa emhlabeni wonke. Ngakho ukusebenzisa "Roundup" ukulungiselela Kunconywa nje kokuthi isistimu ye chemical ngakho ngokuthi isenzo esiqhubekayo, isb ekwelapheni izitshalo Kwenziwa pre-emergence noma ngqo ngaphambi ukuhlwanyelwa. Kufanele kugcizelelwe ukuthi ukhula akanayo umsebenzi zenhlabathi, ezithinta kuphela amahlumela amasha kanye namahlamvu. Ngaphezu kwalokho, ingenye izidakamizwa nephephile kokubili abantu kanye nemvelo. Njengoba lapho ukuthenga "Roundup", kodwa namuhla kusho ungathenga cishe kuzo zonke esitolo ngemikhiqizo for engadini.

Ikhishwa izidakamizwa esebenzayo ewuketshezi, equkethe ukubunjwa yayo, glyphosate, kusebenta njengesikhali isithako esebenzayo, futhi surfactants ekhethekile lula nokugcinwa phezu glyphosate futhi Ukungena kangcono amaqabunga amahlumela. Ngale ngelosi umphumela elihlangene "Roundup" (incwadi yeziyalezo kuyasiqinisekisa ngalokhu) ngempumelelo uba komhlaba nangaphezulu-emhlabathini izingxenye izitshalo, futhi sifinyelele inani ngokubulala dicots utshani, yonyaka futhi ukhula zisetshenziswa.

Ngemuva kwesicelo ngqo izinto asebenzayo nasizayo ekhona yokwakheka ukhula, amahora amane kuya kwayisithupha kwezicubu egxile ngokuphelele. Khona-ke, ngemva kwezinsuku ezinhlanu kuya eziyisikhombisa, lesi sidakamizwa "Roundup" (yokusetshenziswa lokhu njengobufakazi bokuthi) kwasakazwa the izimpande zezitshalo, ukubhidliza zamagama amino acid kanye ngaleyo ndlela yokubangela ukufa simila.

Ngesikhathi esifanayo izimpawu zokuqala isinyathelo of glyphosate (yellowing kanye wilting amahlamvu) kakade lubonakale ngemva kwezinsuku ezinhlanu kuya kweziyishumi emva ukusetshenziswa ukhula. Bawubhubhisa ngokuphelele ukhula emva kwamasonto amabili kuya kwamathathu emva kokwelashwa.

Uma sicabangela izici eziyinhloko ukusetshenziswa kwalesi izidakamizwa, kufanele kuqala kuqashelwe ukuthi sishaye Kunconywa sezulu uzinzo sokukhula kakhulu izitshalo. Imvula, okwakuthatha emva kokwelashwa emahora langaphasi kulangu-eziyisithupha kungase uxubha ngokuphelele chemical kusukela amaqabunga kakhulu ukunciphisa umphumela. Futhi, ningadakwa ezinsukwini zokuqala eziyisihlanu kuya kweziyisikhombisa emva sishaye ukubamba ziba ngcono inhlabathi, ngoba ngalesi sikhathi izimpande zingene izidakamizwa "Roundup". Yokusetshenziswa ugcizelela nokuthi ukuze ugweme ukubhujiswa izitshalo, zinyanga kufanele amboze ifilimu. Ngaphezu kwalokho, ungayisebenzisi ngesikhathi umsebenzi izifutho ne atomization emihle. Ekugcineni, kumelwe ngaso sonke isikhathi khumbula ukuthi izitshalo bazwelane kakhudlwana izidakamizwa "Roundup" engxenyeni ehlobo yesibili kukhona.
