Hoʻokahi wale nō ʻokoʻa ma waena o ka glyphosate a me ka glufosinate-ammonium.Eia nō naʻe, ʻaʻole maopopo loa ka nui o nā mea kūʻai aku a me nā hoa mahiʻai e pili ana i kēia mau "kaikunāne" ʻelua a ʻaʻole hiki ke hoʻokaʻawale maikaʻi iā lākou.No laila he aha ka ʻokoʻa?He ʻokoʻa loa ka Glyphosate a me ka glufosinate!ʻO wai ka mea pepehi maikaʻi i ka nahele?

1. Mechanism o ka hana:Hoʻopaʻa ʻo Glyphosate i ka synthesis protein a lawe ʻia i lalo ma o nā kumu a me nā lau.Loaʻa iā ia ka mana luku ikaika ma nā ʻiʻo o lalo o ka mauʻu i aʻa hohonu a hiki ke hōʻea i ka hohonu i hiki ʻole i nā mīkini mahiʻai maʻamau ke hiki.ʻO Glufosinate kahi mea pepehi ammonium e pale ai i ka glutamine synthesis, e hoʻoulu ai i nā maʻi metabolism nitrogen i nā mea kanu.ʻO ka nui o ka ammonium e hōʻiliʻili i nā mea kanu a hemo nā chloroplasts, no laila ke keʻakeʻa nei i ka photosynthesis o nā mea kanu a hiki i ka make ʻana o ka mauʻu.

2. Systemicity: ʻO Glyphosate ka pūnaewele a me ka conductive, aʻo ka glufosinate he semi-systemic a nāwaliwali loa a ʻaʻole hoʻokō.

3. Ka manawa e pepehi ai i ka nahelehele:No ka mea, ʻo ke kumu o ka hana o ka glyphosate ʻo ka pepehi ʻana i nā aʻa ma o ka hoʻohana ʻana i ka ʻōnaehana, hoʻohana maʻamau ia ma kahi o 7-10 mau lā, aʻo ka glyphosate ka hopena 3-5 mau lā ma hope o ka hoʻohana ʻana.

4. Ka nui o ka weeding:Loaʻa i ka Glyphosate ka hopena hoʻomalu ma luna o 160 mau ʻano nāhelehele, me ka monocotyledonous a me dicotyledonous, makahiki a me ka makahiki, nā mea kanu a me nā kumu lāʻau.Eia naʻe, ʻaʻole maikaʻi kona hopena hoʻomalu i kekahi mau mea ʻinoʻino perennial.ʻAʻole maopopo loa ka hopena o ka glyphosate i nā nāhelehele ʻino kūʻē e like me ka goosegrass, knotweed, a me flyweed;ʻO ka glufosinate he lāʻau lapaʻau ākea, hoʻopili-pepehi, biocidal, non-residual herbicide me ka nui o ka hoʻohana.Hiki ke hoʻohana ʻia ʻo Glufosinate ma nā mea kanu āpau (ʻaʻole hiki ke hoʻopuʻi ʻia ma ka ʻāpana ʻōmaʻomaʻo o ka mea kanu).Hiki ke hoʻohana ʻia no ka hoʻomalu ʻana i ka mauʻu ma waena o nā lālani o nā kumulāʻau huaʻai a me nā mea kanu i kanu ʻia ma nā lālani ākea a ma ka ʻāina hiki ʻole;ʻoi aku ka maikaʻi no nā nāhelehele glyphosate-tolerant.ʻO kekahi mau nāhelehele ʻino, e like me ka cowweed, purslane, a me nā mauʻu dwarf, maikaʻi loa.

5. Palekana:ʻO Glyphosate kahi lāʻau lapaʻau biocidal e pili ana i nā aʻa hua a ʻaʻole hiki ke hoʻohana ʻia i nā māla pāpaʻu.Noho ia i loko o ka lepo a metabolizes no ka manawa lōʻihi.ʻAʻohe o Glufosinate i ka absorption a me ka hopena conduction i ka ʻōnaehana kumu.Hiki ke hoʻololi ʻia i ka lepo i nā lā 3-4.ʻO ka hapalua ola o ka lepo ma lalo o 10 mau lā.He liʻiliʻi ka hopena ma ka lepo, nā aʻa hua a me nā mea kanu hope.
