ʻO ka Metsulfuron methyl, kahi herbicide palaoa maikaʻi loa i hoʻomohala ʻia e DuPont i nā makahiki 1980 mua, no ka sulfonamides a he mea ʻawaʻawa haʻahaʻa i nā kānaka a me nā holoholona. Hoʻohana nui ʻia ia e hoʻomalu i ka lau lau nahele, a he hopena maikaʻi ka hoʻomalu ʻana i kekahi mau mauʻu gramineous. Hiki iā ia ke pale a hoʻomalu pono i nā nāhelehele ma nā māla palaoa, e like me Mainiang, Veronica, Fanzhou, Chaocai, ʻeke kahu hipa, ʻeke ʻeke kahu hipa haki, Soniang Artemisia annua, album Chenopodium, Polygonum hydropiper, Oryza rubra, a me Arachis hypogaea.
ʻO kāna hana he 2-3 mau manawa ma mua o ka chlorsulfuron methyl, a ʻo kāna ʻano hana hoʻoponopono koʻikoʻi he maloʻo maloʻo a i ʻole ka pauka wai. Eia nō naʻe, ma muli o kāna hana kiʻekiʻe, ka luku nui ʻana i ka mauʻu, ka pili ikaika, a me ka hoʻohana ākea i ka honua, waiho ia i ka nui o nā koena i loko o ka lepo, a ʻo kona hopena koʻikoʻi lōʻihi e lilo i mea hoʻoweliweli i ke kaiaola kaiaola. no laila ua hoʻopau mālie ʻia kona inoa inoa ma 2013 ma Kina. I kēia manawa, ua pāpā ʻia ka hoʻohana ʻana ma Kina, akā ua hoʻohana nui ʻia ia ma ka mākeke honua, a hiki nō ke hoʻopaʻa i ka hoʻopaʻa inoa ʻana ma Kina. ʻO ʻAmelika Hui Pū ʻIa a me Pasila ʻo ia nā mākeke kūʻai nui ʻelua o ka methasulfuron methyl ma Kina.
ʻAno kino a me kemika
ʻO ka lāʻau lapaʻau ʻenehana he paʻa keʻokeʻo ʻole, me kahi helu heheʻe o 163 ～ 166 ℃ a me kahi kaomi mahu o 7.73 × 10-3 Pa/25 ℃. He ʻokoʻa ka hiki ʻana o ka wai me ka pH: 270 ma ka pH 4.59, 1750 ma ka pH 5.42, a me 9500 mg/L ma ka pH 6.11.
Kaʻawaʻawa
He haʻahaʻa loa ka ʻona i nā holoholona koko pumehana. ʻOi aku ka LD50 waha o nā ʻiole ma mua o 5000 mg/kg, a he haʻahaʻa ka ʻona i nā holoholona wai. ʻO kāna hoʻohana ākea e waiho i ka nui o nā koena i loko o ka lepo, kahi e hoʻoweliweli ai i ke kaiaola kaiaola wai, e like me ka hoʻohaʻahaʻa ʻana i ka nui o ka cell density o Anabaena flosaquae, he mea nui ka pale ʻana i ka acetyllactic acid synthase (ALS) o Anabaena. flosaquae.
ʻAno hana
Hoʻohana nui ʻia ka Metsulfuron methyl no ka hoʻomalu ʻana i nā nāhelehele ākea ākea ma nā māla palaoa, a hiki nō ke hoʻomalu i kekahi mau mauʻu gramineous. Hoʻohana nui ʻia ia no ka mālama ʻana i ka lepo ma mua o ka kanu ʻana a i ʻole ma hope o ke kumu kanu a me ka ʻōpala lau. ʻO ka hana nui o ka hana, ʻo ia ma hope o ka hoʻopili ʻia ʻana e nā ʻiʻo mea kanu, hiki iā ia ke alakaʻi koke i luna a i lalo i ke kino o ka mea kanu, kaohi i ka hana o ka acetolactate synthase (ALS), pale i ka biosynthesis o nā waikawa amino pono, kaohi ʻana i ka ʻāpana cell a me ka ulu ʻana, e kanu i nā mea kanu i ʻōmaʻomaʻo, ka ulu ʻana o ka necrosis, ka lau wilting, a laila kanu mālie i ka maloʻo, kahi palekana no ka palaoa, ka bale, ka oats a me nā mea kanu palaoa ʻē aʻe.
Hui nui
metsulfuron-methyl 0.27% + bensulfuron-methyl 0.68% + acetochlor 8.05% GG (Macrogranule)
metsulfuron-methyl 1.75% + bensulfuron-methyl 8.25% SP
metsulfuron-methyl 0.3% + fluroxypyr 13.7% EC
metsulfuron-methyl 25% + tribenuron-methyl 25%
metsulfuron-methyl 6.8% + thifensulfuron-methyl 68.2%
Kaʻina hana synthetic
Hoʻomākaukau ʻia ia mai kāna koʻikoʻi koʻikoʻi, methyl phthalate benzene sulfonyl isocyanate (ʻo ke ʻano synthesis like me bensulfuron methyl), 2-amino-4-methyl-6-methoxy-triazine a me dichloroethane, ma hope o ka pane ʻana i ka lumi wela, kānana a me ka desolvation.
ʻO nā ʻāina kūʻai nui
Wahi a ka ʻikepili kuʻuna, ʻo ka lawe ʻana aku o Kina i ka metsulfuron methyl i ka makahiki 2019 ma kahi o 26.73 miliona mau kālā, ʻo ia ka United States ka mākeke nui loa o ka metsulfuron methyl, me ka huina o 4.65 miliona mau kālā i ka makahiki 2019, ʻo Brazil ka lua o ka mākeke nui loa. lawe mai ma kahi o 3.51 miliona kālā ma 2019, ʻo Malaysia ke kolu o ka mākeke nui loa, a me ka lawe ʻana mai o 3.37 miliona mau kālā ma 2019. ʻO Indonesia, Colombia, Australia, New Zealand, India, Argentina a me nā ʻāina ʻē aʻe he mau mea lawe waiwai nui o methyl sulfuron.
