1. Introduction to Diquat

ʻO Diquat ke kolu o ka herbicide biocidal kaulana loa ma ka honua ma hope o ka glyphosate a me ka paraquat.ʻO Diquat kahi lāʻau lapaʻau bipyridyl.No ka mea he bromine atom i loko o ka ʻōnaehana bipyridine, loaʻa iā ia kekahi mau waiwai ʻōnaehana, akā ʻaʻole ia e hōʻino i nā aʻa hua.Hiki ke alakaʻi ʻia i luna ma o ka phloem o ka mea kanu, no laila ʻoi aku ka maikaʻi ma mua o ka glyphosate.a me ka glufosinate e pepehi koke i ka mauu.Ke hoʻohana ʻia ma nā mahina ʻai, pepehi pinepine ʻia nā mauʻu i ʻeli ʻia ma mua a ma hope o ka lūlū ʻana i nā mea kanu a ma mua o ka puka ʻana mai, a i ʻole ke hoʻohana ʻia ʻana o ka pulupulu kuhikuhi i waena o ka lālani i ka wā hope o ka puka ʻana o nā mea kanu.Ma ka manawa like, ʻo ka diquat kekahi mea hoʻopili hoʻopili a hiki ke hoʻohana ʻia ma ke ʻano he mea maloʻo / ʻoʻo ma mua a ma hope o ka ʻohi ʻana a ma ke ʻano he desiccant no nā hua kanu.

2. E pili ana i ka laula hua o ka diquat

ʻOi aku ka maikaʻi o Diquat ma mua o ka paraquat a ʻoi aku ka maikaʻi o ka hopena i nā lau lau ākea.He kūpono ia no ka weed ma mua o ka lūlū ʻana ma nā ʻāina mahi ʻole a mahi ʻole, nā māla māla, a me ka weeding ma waena o nā lālani mea kanu.Hiki ke hoʻohana ʻia no ka ʻohi ʻana i nā mea kanu e like me ka soybeans, ʻuala, a me ka pulupulu.Hoʻoulu ka mea mua i ka maloʻo a me ka defoliation.

3. He aha nā pōmaikaʻi o ka diquat?

①. Nā waiwai hana wikiwiki: ʻO ka Diquat a me ka paraquat nā lāʻau herbicide bipyridyl a loaʻa i nā ʻano like ʻole e pili ana i nā waiwai herbicidal.ʻOi aku ka wikiwiki o ka pepehi ʻana i nā nahele ma mua o ka paraquat.Hoʻomaka ia i ka lā hoʻokahi, a hoʻomaka ka mauʻu e make i loko o 24 mau hola.Hoʻokahi hola ka ua ma hope o ke kāpī ʻana, ʻaʻohe hopena liʻiliʻi i ka pono.

②.ʻO ka palekana maikaʻi, ka wai a me ka mālama lepo: ʻOiai aia kekahi mau waiwai systemic diquat, ʻaʻole ia e hōʻino i ka ʻōnaehana kumu o nā mea kanu, a ʻo ka hoʻopili-pepehi ma hope o nā mea āpau.No laila, hoʻomau ka diquat i nā hiʻohiʻona palekana o ka paraquat me ke koena ʻole a ʻaʻohe pilikia drift.No ka mea, ʻaʻole pepehi ka mauʻu ʻenemi i nā aʻa, ua kūpono ia i ka mālama ʻana i ka wai a me ka lepo, a ʻaʻole maʻalahi ka hiolo ʻana o nā kualono.

③.Ka hopena kūikawā ma ka lau lau nahele: Ua ʻoi aku ka maikaʻi o ka mana ʻo Diquat ma mua o ka glufosinate ma kekahi mau mauʻu kūpaʻa, ʻoi aku ka lau ākea.

④.ʻO ka pale wela haʻahaʻa: Ke emi ka mahana ma mua o 15 ℃, ʻoi aku ka maikaʻi o ka hopena weeding ma mua o ka glufosinate-ammonium.

4. Pehea e hoʻohana pono ai iā Diquat?

①.Weeding i ka ʻāina wao nahele: Hiki ke hoʻohui pono ʻia kekahi glyphosate, a e hōʻemi nui ʻia ka hoʻihoʻi hou ʻana o nā mauʻu i ka pae hope.E like me ka dosage kikoʻī, hiki iā ʻoe ke hoʻokolohua mua ma kahi wahi liʻiliʻi e like me nā kūlana weed kūloko.

②. No kekahi mau nāhelehele i hoʻomalu ʻia e Gramineae, hiki iā ʻoe ke hoʻohui i ka quizalofop, clethodim, flufenofop, a me nā mea ʻē aʻe e hoʻonui i ka spectrum herbicidal, a hiki i ka manawa hoʻomalu weed ma kahi o 30 mau lā.

③.No ka mea, ʻo ka diquat ka mea maʻamau no ka pepehi kanaka, i ka wā e pīpī ʻia ai ka diquat, pono e hoʻopuʻi ʻia me ka pono.Hiki ke hoʻohui pū ʻia nā mea hoʻopaʻa e like me ka silika organik i hiki ke hoʻopili pono ʻia ka ʻili o ka lau nahele a hoʻopaʻa i ka diquat e loaʻa ai nā hopena maikaʻi aʻe.He hopena pepehi mauu maikaʻi.

④.I ka hoʻoheheʻe ʻana i ka diquat, mai hoʻohana i ka wai kahawai turbid e pale ai i ka hōʻemi ʻana o ka pono o ka lāʻau.

⑤.E ho'āʻo e hoʻohana i ka pesticide ma hope o ka pau ʻana o ka hau i ke kakahiaka.Ke ʻike ʻia ka lā i ke awakea, e ʻike ʻia ka hopena pili a ʻoi aku ka wikiwiki o ka hopena.(E kau i ka lāʻau i ka pō ma mua o ka hau, no laila e ʻoi aku ka maikaʻi o ka lāʻau)
