Metsulfron methyl, mushonga wegorosi unoshanda zvakanyanya wakagadzirwa neDuPont mukutanga kwema1980, ndeye sulfonamides uye ine muchetura wakaderera kuvanhu nemhuka. Inonyanya kushandiswa kurwisa sora rakafara, uye ine simba rekudzora mamwe masora egramineous. Inogona kudzivirira nekudzora masora zvinobudirira muminda yegorosi, yakadai seMainiang, Veronica, Fanzhou, Chaocai, chikwama chemufudzi, chikwama chemufudzi chakaputsika, Soniang Artemisia annua, Chenopodium album, Polygonum hydropiper, Oryza rubra, uye Arachis hypogaea.
Basa rayo ndeye 2-3 nguva iyo yechlorsulfuron methyl, uye iyo huru yekugadzirisa dosage fomu ndeyekumira kwakaoma kana hupfu hwakanyorova. Nekudaro, nekuda kwekuita kwayo kwepamusoro, kuuraya sora kwakawanda, kusimba kwakasimba, uye kushandiswa kwakakura munyika, inosiya huwandu hukuru hwezvisaririra muvhu, uye mhedzisiro yayo yenguva refu yekusarira ichaisa njodzi kunharaunda yemvura. saka kunyoreswa kwayo kwakadzimwa zvishoma nezvishoma muna 2013 kuChina. Parizvino, kushandiswa kwayo muChina kwakarambidzwa, asi ichiri kushandiswa zvakanyanya mumusika wepasi rose, uye ichiri kukwanisa kubata kunyoresa kunze kwenyika kuChina. IUnited States neBrazil ndiyo misika miviri yepamusoro yekutengesa methasulfuron methyl muChina.
Zvenyama uye zvemakemikari zvinhu
Mushonga wehunyanzvi muchena, usinganhuhwi, une nzvimbo yekunyungudika inosvika 163 ～ 166 ℃ uye mhute ye7.73 × 10-3 Pa/25 ℃. Kunyungudika kwemvura kunosiyana nepH: 270 papH 4.59, 1750 papH 5.42, uye 9500 mg/L papH 6.11.
Muchetura
Hupfu hwemhuka dzine ropa rinodziya hwakaderera. Iyo yemuromo LD50 yemakonzo inopfuura 5000 mg/kg, uye chepfu kumhuka dzemumvura yakaderera. Kushandiswa kwayo kwakapararira kuchasiya nhamba huru yezvisaririra muvhu, izvo zvinozoisa njodzi kune nharaunda yemvura yezvisikwa, senge kuderedza density yesero yeAnabaena flosaquae, ine inhibition yakakura pane acetyllactic acid synthase (ALS) yeAnabaena. flosaquae.
Action mechanism
Metsulfuron methyl inonyanya kushandiswa kudzora masora ane mashizha akafara muminda yegorosi, uye inogona zvakare kudzora mamwe masora ane gramineous. Inonyanya kushandiswa pa pre seedling ivhu kurapwa kana post seedling dzinde uye mashizha spray. Iyo huru nzira yekuita ndeyekuti mushure mekunyudzwa nemuti wezvirimwa, inogona kukurumidza kuita kumusoro uye pasi mumuviri wechirimwa, inhibit basa reacetolactate synthase (ALS), kudzivirira biosynthesis yeakakosha amino acids, inhibit kupatsanurwa kwesero uye kukura, ita mbesa dzakasvibira, growth point necrosis, mashizha kusvava, wozodyara zvishoma nezvishoma zvichisvava, izvo zvakachengeteka kugorosi, bhari, oats nezvimwe zvirimwa zvegorosi.
Main compound
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% + trinuron-methyl 25%
metsulfuron-methyl 6.8% + thifensulfuron-methyl 68.2%
Synthetic process
Yakagadzirirwa kubva kune yakakosha yepakati, methyl phthalate benzene sulfonyl isocyanate (iyo yakafanana synthesis nzira se bensulfuron methyl), 2-amino-4-methyl-6-methoxy-triazine uye dichloroethane, mushure mekuita pane tembiricha yekamuri, kusefa uye kupera.
Nyika huru dzekutengesa kunze
Zvinoenderana nedata retsika, kutengeswa kweChina kwemetsulfuron methyl muna 2019 kwakasvika madhora 26.73 miriyoni, iyo United States ndiyo yaive musika mukuru wemetsulfuron methyl, ine hupfumi hwakazara hwemadhora mazana mana nemakumi matanhatu emadhora muna 2019, Brazil yaive musika wechipiri pakukura. kutengeswa kunze kwenyika kunosvika 3.51 miriyoni emadhora muna 2019, Malaysia yaive musika wechitatu pakukura, uye kutengwa kunze kwenyika kwemadhora 3.37 miriyoni muna 2019. Indonesia, Colombia, Australia, New Zealand, India, Argentina nedzimwe nyika dzakakosha vatengesi vemethyl sulfuron.
