Kukhona umehluko wegama elilodwa kuphela phakathi kwe-glyphosate ne-glufosinate-ammonium.Kodwa-ke, abathengisi abaningi bezinto zokulima kanye nabangane babalimi abakacaci kahle ngalaba "bafowethu" ababili futhi abakwazi ukubehlukanisa kahle.Uyini-ke umehluko?I-Glyphosate ne-glufosinate zihluke kakhulu!Ubani obulala ukhula kangcono?

1. Indlela yokwenza:I-Glyphosate ivimba ukwakheka kwamaprotheni futhi idluliselwa ngaphansi komhlaba ngeziqu namaqabunga.Inamandla anamandla okubhubhisa ezicutshini ezingaphansi komhlaba zokhula olunezimpande ezijulile futhi ingafinyelela ekujuleni imishini evamile yezolimo engeke ifinyelele kuyo.I-Glufosinate iwuhlobo lokubulala oluthinta i-ammonium oluvimbela ukwakheka kwe-glutamine, okubangela ukuphazamiseka kwe-nitrogen metabolism ezitshalweni.Inani elikhulu le-ammonium linqwabelana ezitshalweni futhi ama-chloroplasts ahlakazeke, ngaleyo ndlela avimbele i-photosynthesis yezitshalo futhi ekugcineni aholele ekufeni kokhula.

2. Ukuhleleka: I-Glyphosate i-systemic futhi i-conductive, kuyilapho i-glufosinate i-semi-systemic noma ibuthakathaka kakhulu futhi ayiqhubeki.

3. Isikhathi sokubulala ukhula:Njengoba isimiso sesenzo se-glyphosate ukubulala izimpande ngokumuncwa kwesistimu, ngokuvamile siqala ukusebenza ezinsukwini ezingaba ngu-7-10, kuyilapho i-glyphosate iqala ukusebenza ezinsukwini ezingu-3-5 ngemva kokusetshenziswa.

4. Ububanzi bokhula:I-Glyphosate inomphumela wokulawula ezinhlotsheni zokhula ezingaphezu kuka-160, okuhlanganisa i-monocotyledonous kanye ne-dicotyledonous, yonyaka kanye ne-perennial, amakhambi nezihlahla.Nokho, umphumela wawo wokulawula ukhula oluyingozi olungapheli awulungile.Umthelela we-glyphosate awubonakali kahle okhulani oluyingozi olungazweli olufana ne-goosegrass, i-knotweed, ne-flyweed;I-glufosinate iwumuthi obanzi, obulala ukuthintana, obulala ukhula, ongasaleli onezinhlobonhlobo zokusetshenziswa.IGlufosinate ingasetshenziswa cishe kuzo zonke izitshalo (ayikwazi ukufuthwa engxenyeni eluhlaza yesitshalo).Ingasetshenziselwa ukulawula ukhula phakathi kwemigqa yezihlahla zezithelo nemifino etshalwe emigqeni ebanzi nasendaweni engalimeki;ikakhulukazi ukhula olubekezelela i-glyphosate.Olunye ukhula oluyingozi, njenge-cowweed, i-purslane, nokhula oluncane, lusebenza kakhulu.

5. Ukuphepha:I-Glyphosate isibulala-zinambuzane esibulala ukhula esithinta izimpande zezitshalo futhi ayikwazi ukusetshenziswa ezinsimini ezinezimpande ezingajulile.Ihlala emhlabathini futhi i-metabolizes isikhathi eside.I-Glufosinate cishe ayinawo umphumela wokumunca nowokwenziwa ohlelweni lwempande.Ingenziwa i-metabolized emhlabathini ezinsukwini ezingu-3-4.Ingxenye yempilo yomhlabathi ingaphansi kwezinsuku eziyi-10.Inomthelela omncane emhlabathini, ezimpandeni zezitshalo nasezitshalweni ezilandelayo.
