I loko o kahi hālāwai ninaninau me Syngenta's Herbicide US Technical Product Director, Dane Bowers, i kahi ninaninau e pili ana i ka pane ʻana o nā mea kūʻai aku a me nā mea ulu i ka manawa 2021, ua ʻōlelo ʻo ia i kāna leka lawe home i nā makahiki i hala iho nei: pilikia ʻenehana.Pilikia pili.
"Mai kahi ʻike loea, manaʻo wau he manaʻo maikaʻi loa kā mākou.Aia nā pilikia - mai kuhi hewa iaʻu," i ʻae ʻo ia, "akā he mau mea maʻamau mākou a pau.Inā hana ia no mākou, hana mākou i ka hana like. "
Makemake mākou e noʻonoʻo e lawe mai ʻo 2021 i ka hoʻōla ma nā ʻano āpau, akā a hiki i kēlā manawa, he manawa maikaʻi loa kēia e hoʻomaopopo i ke ʻano o ka hoʻokele weed.ʻIke wale i kekahi mau nahele i pakele, akā ʻaʻole nui loa?Manaʻo ʻo Bowles: "He canary kēlā i loko o kahi lua lanahu.""I ka manawa e ʻike ai ʻoe i nā hanana heʻe i ka nahelehele, pono ʻoe e noʻonoʻo inā ua lōʻihi ka lōʻihi o koʻu hoʻohana ʻana i ka papahana, a inā ʻaʻole wau i hoʻokomo i nā wahi hana ʻē aʻe i kaʻu papahana herbicide.He aha nā hana ʻē aʻe aʻu e hana ai e pale aku i kēia kūlana?ʻO ka maʻamau, i ka makahiki mua o ke kūʻē ʻana, ʻaʻole ʻoe i manaʻo he pilikia kāu, a laila i ka makahiki mua Ua ʻoi aku ka ʻino i loko o ʻelua mau makahiki.I ke kolu o ka makahiki, he poino.He ʻanuʻu maoli nō ia i mua.
Ma ka papa inoa o nā ʻōlelo aʻoaʻo a Bowers no ke kau e hiki mai ana, a i kākoʻo ʻia e ka lehulehu agronomists, ʻo ia: 1) hoʻomaopopo i nā pilikia kūikawā o kēlā me kēia mahiʻai i hāʻawi ʻia, a me nā lāʻau herbicides, a 2) hoʻomaopopo i ka pono e hoʻomaka i ka hoʻomaʻemaʻe a mālama i ka maʻemaʻe.ʻO ia ke ʻano o ka hoʻohana ʻana i nā lāʻau lapaʻau koena ikaika ma mua o ka puka ʻana mai, a laila hoʻopili i ke koena o nā lāʻau lapaʻau overlapping 14 a 21 mau lā ma hope.Pono nā herbicides e hoʻohui i nā wahi kūpono e hōʻemi i ka pilikia o ke kanu ʻana i nā nāhelehele kūpaʻa.
"ʻO ka hapa nui loa ka hapa paʻakikī.ʻO kaʻoiaʻiʻo, ua pili mākou i ka hoʻolālā no ka mea e pale aku ke kumukūʻai a me nā kūlana kūlohelohe iā mākou mai ka hana ʻana i ka hoʻoholo kūpono, "wahi a Drake Copeland, FMC Technical Services Manager ma Ohio, Michigan.
Ua ʻōlelo ʻo Wolfe: "Ke manaʻo nei au i ka wā e noʻonoʻo ai i ka herbicides, ʻo kahi papahana koena maikaʻi me nā ʻano hana he nui ʻo ia kekahi o kāu koho mua.""Ke holo ʻoe ma ke komohana i ʻAukake a me ka hoʻomaka ʻana o Kepakemapa, He maʻalahi loa ka hiʻohiʻona āu e ʻike ai.Ua emi ke koena o kēia poʻe, a ua hoʻohui hou ʻia nā koena i ke kau.Maikaʻi loa ko lākou mau mahina ʻai a ʻaneʻane ʻaʻohe hōʻiliʻili wai.ʻO ka poʻe i hoʻokuʻu i ke koena, Minnesota, Iowa a me Dakota ua ʻike paha i ka nui o ka cannabis i ka hopena o ke kauwela a me ka hāʻule mua.
Ua hoʻokūpaʻa ʻo Bowers i ke koʻikoʻi o ka hoʻohana ʻana i nā lāʻau herbicide ma mua o ka ulu ʻana i nā huahana dicamba, ʻoi aku ka nui o ka noʻonoʻo ʻana ua ʻike mua ʻo Kauka Larry Steckel o ke Kulanui o Tennessee (L) iā Palmer e kūʻē i ka dicamba.
Ua kākau ʻo Steckel ma kāna blog UT e nānā ana i ka 2021, pono i kēia manawa ke kau mua i nā koena i kūpono no Palmer.Eia kekahi, pono e hoʻohana koke ʻia ke kūʻokoʻa ma hope o ka hoʻohana ʻana o dicamba e hoʻopau i ka pakele.
Ua kuhikuhi ʻo Steckel ʻo kēia ka lima o ka hana herbicide i hana ʻia e Palmer ma Tennessee mai ka makahiki 1994. "Inā mākou e puʻunaue i nā makahiki 26 me nā ʻano hana 5, e hōʻike ana ka makemakika e hoʻomohala ka mauʻu i ke kūʻē ʻana i nā herbicides maikaʻi i loko o 5.2 mau makahiki ākea. hoʻohana."
I loko o ka waihona huahana a Syngenta, ʻo kāna ʻenehana Tavium Plus VaporGrip dicamba premix i loaʻa iā S-alachlor, e hāʻawi ana i ʻekolu pule o ka hana koena ma mua o ka dicamba wale nō.Wahi a ka hui, ke hoʻohana ʻia nā herbicides ma hope o ka puka ʻana i nā herbicides ma mua o ka puka ʻana (e like me Boundary 6.5 EC, BroadAxe XC a i ʻole Prefix herbicides), "ʻo ia ka manawa maikaʻi loa e hāʻawi i ka herbicide post-emergence i loko o ka soybeans i hoʻokahi ala".
"He huahana ikaika loa kēia, ʻaʻohe mea i loaʻa iā ʻoe, hiki iā ʻoe ke hoʻomalu i ka mauʻu ma mua o ka soybeans, a hāʻawi ia i kahi pae o ka maʻalahi no ka mea ʻaʻole mākou e hoʻokomo i nā hua a pau i loko o ke koena puʻupuʻu.Hiki iā ʻoe ke hoʻi koke mai e hoʻohana i ka hui 15 o nā herbicides, a loaʻa pū kekahi i ka nui o ka xylazine.Ua haʻi aku ʻo Kauka Daniel Beran, Nufarm US Technical Services Director, iā CropLife®.
"Hiki iā mākou ke hoʻopau i kekahi mau kānalua a hoʻokumu i kahi kaʻina hana burnout a me ke koena me ka maʻalahi.Inā hoʻololi nā hiʻohiʻona a i ʻole nā ​​​​mea hana noi i ka mea kanu i kaupalena ʻia a hoʻololi paha kekahi mau manawa noi, a laila pono e loaʻa kahi maikaʻi.Ua kuhikuhi ʻo ia i kēia manawa no Nufarm, he mea hoihoi ia i ke kolu o ka ʻaoʻao ma ke kahua o ka dicamba a me ka ʻenehana 2,4-D.ʻO ka manawa-hiki i nā ʻelele hui ke kōkua i nā mea kūʻai aku e aʻo hou i nā kumu.
ʻO Reviton kahi huahana hou i hoʻopau ʻia ma mua o ka mea kanu i hoʻokumu ʻia e Helm Agro ma ʻAmelika Hui Pū ʻIa.ʻO ia ka mea hoʻopale PPO herbicide me kahi mea hana hou ʻo Tergeo no ka māla palaoa, pulupulu, soybeans a me ka palaoa.Ma mua o 700 mau ho'āʻo hoʻomohala huahana ʻAmelika ʻAmelika a me nā noiʻi hoʻoponopono, ua hōʻoia ʻo Reviton "ʻoi aku ma mua o 50 lau ākea a me nā mauʻu (me ka ALS, triazine a me nā ʻano glyphosate resistant) he mea hoʻohiki maikaʻi loa no ka mālama ʻana i ke ahi.
Me ka hāʻule ʻana o nā kumukūʻai kūʻai, ua ʻike ʻo Copeland i nā mea kanu maikaʻi (hoʻonui i nā mea kanu) a me nā kūlana maikaʻi ʻole (hoʻemi ʻia ka hoʻohana ʻana i ka herbicide).
Ua ʻōlelo ʻo ia: "ʻO nā koena herbicide i ka noi hope loa ke kī i ka mālama ʻana i ke koena o ka weed control e koi ʻia no ka mea e pani ʻia i ka canopy," i ʻōlelo hou ai ʻo ia, "Eia kekahi, e mālama ʻole ʻia nā koena herbicides i kekahi noi.ʻO ka hoʻonui ʻana i ka hoʻihoʻi ʻana o nā ʻanoʻano i ka waihona hua lepo e ʻae ʻia ka nui o ke kālā e hoʻolilo ʻia no nā ala hou ma ke kula e hoʻomaʻemaʻe i ka ʻōpala.
Ua kāhea ʻo Copeland i ke Kulanui ʻo Purdue e hana i ka noiʻi, kahi i ʻike ai ʻo ke koena overlap ke ala wale nō e hōʻemi ai i ka mālama ʻana i ka waihona hua makahiki mua.ʻO ka hoʻomaʻamaʻa ʻana me ka ʻole o ka hoʻopili ʻana i nā koena herbicides me nā wahi he nui o ka hana i hopena i ka piʻi nui ʻana o ka nui o ka hemp wai ʻai i ka waihona hua.ʻO ka ʻokoʻa, ua hoʻohana ke kaʻina hana koena ma hope o ka puka ʻana i ke koena e hoʻemi i ka wela o ka wai i 34% (e ʻike i ke kiʻi ma lalo).
Ua ʻōlelo ʻo ia: "Hiki i nā ʻikepili e like me kēia ke kōkua i kā mākou mea kūʻai aku a me nā agronomists e kamaʻilio me nā mea ulu.""Hiki iā lākou ke ʻōlelo, 'Ua ʻike wau he paʻakikī nā manawa, akā inā makemake mākou e hoʻokō i ka wā e hiki mai ana i kāu mahiʻai, a laila ʻaʻole pono mākou e ʻoki i kekahi mea, inā ma ka hale hana a ma luna paha, hiki iā mākou ke hōʻemi i ke koena. herbicide.'” ”
E like me kā Dr. Bob Hartzler i wehewehe ai i loko o ka Iowa State University Integrated Pest Management Blog: “Ma muli o ka hoʻonui wikiwiki ʻana o nā mauhele kūʻokoʻa herbicide, ua pilikia nā ʻano hoʻokele weed o Iowa i kēia manawa No ka mālama ʻana i ka maikaʻi o nā herbicides, ʻelua mau mea e pono ai: 1) hoʻohana i ka hoʻokele weed integrated;2) e hoʻololi i ka pahuhopu o ka mālama ʻana i ka mauʻu mai ka pale ʻana i nā mea kanu i ka hoʻemi ʻana i ka nui o nā waihona hua mauʻu.ʻO ka koi mua e hoʻololi i ka Behavior, ʻo ka lua e koi i ka loli o ka ʻano.
Ma waho aʻe o ka hoʻokuʻu ʻana i nā koena mua, ua ʻōlelo pū ʻo Syngenta's Bowers i nā lāʻau lapaʻau "hoʻopunipuni" e mālama i ke kālā.
Ua hoʻolauna ʻo Bowers i ka hōʻike hoʻopaʻa paʻa maʻamau i hana ʻia e Syngenta ma nā huahana maʻamau.Inā ʻaʻole i hoʻonohonoho pono ʻia nā mea hana, hiki i ka AI ke hoʻouka kekahi i kekahi a hoʻohaʻahaʻa i nā herbicides i loaʻa.Ke hoʻohana ka mea ulu i kahi huahana kahi e hana ai ʻo 80% wale nō o AI, ʻaʻole hiki iā ia ke hālāwai wale i nā pilikia hui ʻana, akā hiki nō iā ia ke hoʻohana iā ia ma kahi ratio haʻahaʻa ma mua o ka lepili a ʻoi aku ka haʻahaʻa o ka hopena herbicidal ma mua o ka mea i manaʻo ʻia.
Ua ʻōlelo ʻo Bowers he hiʻohiʻona kikoʻī ka poʻe e hoʻohana i kahi ʻano maʻamau, ʻo ia ka hui pū ʻana o AI S-metolachlor i Dual II Magnum a me AI mesotrione ma Callisto, hiki iā Syngenta ke hāʻawi i kahi ʻano premixes corn, e like me Acuron.I loko o kahi premix o mesotrione a me S-metolachlor, "Inā ʻaʻole i hoʻonohonoho pono ʻia ʻo S-metolachlor, e hoʻohaʻahaʻa ia i ka mesotrione i loaʻa."
Ua ʻōlelo hou ʻo Bowers: “He ʻoi aku ka maikaʻi o ka hoʻoholo ʻana e hoʻolilo i kekahi mau kālā ma mua a hoʻoponopono i ka hoʻolālā herbicide e hāʻawi i nā hopena weeding ʻoi aku ka maikaʻi, i ʻoi aku ka maikaʻi o nā busela i kēlā me kēia ʻeka.Ke emi mai ke kumu kūʻai, e hoʻonui i nā busela he nui kāu kī.ʻAʻole mākou e mālama i ke ala o ka pōmaikaʻi, no laila pono mākou e mālama i ke koena o ka hoʻolilo ʻana, akā pono mākou e hōʻoia e loaʻa iā ʻoe ka waiwai o kāu hoʻopukapuka a me ka hoʻihoʻi ʻana i nā kālā.
