Kukho umahluko wegama elinye kuphela phakathi kwe-glyphosate kunye ne-glufosinate-ammonium.Nangona kunjalo, abathengisi abaninzi bezolimo kunye nabahlobo babalimi abakacaci kakuhle malunga naba "bazalwana" babini kwaye abakwazi ukwahlula kakuhle.Ngoko ke yintoni umahluko?I-Glyphosate kunye ne-glufosinate zihluke kakhulu!Ngubani obulala ukhula ngcono?

1. Indlela yokwenza:I-Glyphosate ivimba iprotein synthesis kwaye idluliselwa ngaphantsi komhlaba ngeziqu kunye namagqabi.Inamandla awonakalisayo awomeleleyo kwizicubu ezingaphantsi komhlaba zokhula olunengcambu enzulu kwaye inokufikelela kubunzulu obungenakufikelelwa ngoomatshini bezolimo abaqhelekileyo.I-Glufosinate kukubulala ukudibana kwe-ammonium inqanda ukuhlanganiswa kwe-glutamine, okubangela ukuphazamiseka kwe-nitrogen metabolism kwizityalo.Isixa esikhulu se-ammonium siqokelela kwizityalo kunye nekloroplasts zichithakala, ngaloo ndlela zithintela i-photosynthesis yezityalo kwaye ekugqibeleni zikhokelela ekufeni kokhula.

2. Inkqubo: I-Glyphosate i-systemic kunye ne-conductive, ngelixa i-glufosinate i-semi-systemic okanye ibuthathaka kakhulu kwaye i-non-conductive.

3. Ixesha lokubulala ukhula:Ekubeni umgaqo wesenzo se-glyphosate kukubulala iingcambu nge-systemic absorption, ngokuqhelekileyo iqala ukusebenza malunga neentsuku ze-7-10, ngelixa i-glyphosate ithatha i-3-5 iintsuku emva kokusetyenziswa.

4. Umda wolukhula:I-Glyphosate inempembelelo yokulawula ngaphezu kweentlobo ze-160 zokhula, kubandakanywa i-monocotyledonous kunye ne-dicotyledonous, yonyaka kunye ne-perennial, imifuno kunye nezihlahla.Nangona kunjalo, impembelelo yalo yokulawula ukhula oluyingozi oluhlala ixesha elide ayifanelekanga.Impembelelo ye-glyphosate ayibonakali kakhulu kukhula olunobungozi oluxhathisayo olufana ne-goosegrass, i-knotweed, kunye ne-flyweed;I-glufosinate sisichiza esibanzi, esibulala ukhula, sibulala ukhula, sibulala ukhula esingashiyekiyo esinoluhlu olubanzi lokusetyenziswa.IGlufosinate ingasetyenziswa phantse kuzo zonke izityalo (ayinakutshizwa kwindawo eluhlaza yesityalo).Ingasetyenziselwa ukutshatyalaliswa kokhula phakathi kwemiqolo yemithi yeziqhamo nemifuno etyalwe kwimiqolo ebanzi nakumhlaba ongalinywayo;ngakumbi ukhula olunyamezelayo kwi-glyphosate.Olunye ukhula oluyingozi, njenge-cowweed, i-purslane, kunye nokhula oluncinci, lusebenza kakhulu.

5. Ukhuseleko:IGlyphosate sisichiza esibulala ukhula esichaphazela iingcambu zesityalo kwaye asinakusetyenziswa kumabhoma aneengcambu ezinganzulwanga.Ihlala emhlabeni kwaye i-metabolizes ixesha elide.I-Glufosinate phantse ayinayo i-absorption kunye ne-conduction effect kwinkqubo yeengcambu.Inokuthi ifakwe kwi-metabolized emhlabeni ngeentsuku ezi-3-4.Ubomi besiqingatha somhlaba bungaphantsi kweentsuku ezili-10.Inempembelelo encinci emhlabeni, iingcambu zesityalo kunye nezityalo ezilandelayo.
