Metsulfuron methyl, oo ah dhir-daaqsimeed sarreen ah oo aad waxtar u leh oo ay samaysay DuPont horraantii 1980-meeyadii, waxa iska leh sulfonamides waana sun ku yar bini'aadamka iyo xayawaanka. Inta badan waxaa loo isticmaalaa in lagu xakameeyo haramaha ballaaran, waxayna saameyn wanaagsan ku leedahay haramaha qaar. Waxay si wax ku ool ah uga hortagi kartaa oo u xakameyn kartaa haramaha beeraha sarreenka ah, sida Mainiang, Veronica, Fanzhou, Chaocai, boorsada adhijirka, kiishashka adhijirka jaban, Soniang Artemisia annua, album Chenopodium, Polygonum hydropiper, Oryza rubra, iyo Arachis hypogaea.
Shaqadeedu waa 2-3 jeer ta chlorsulfuron methyl, iyo qaabka ugu muhiimsan ee habka qiyaasta qiyaasta waa ganaax qalalan ama budada qoyan. Si kastaba ha ahaatee, iyada oo ay ugu wacan tahay waxqabadkeeda sarreeya, dilitaanka haramaha ballaaran, dareenka xooggan, iyo adeegsiga ballaaran ee adduunka, waxay ka tagtaa tiro badan oo hadhaaga ah ee ciidda, iyo saameynteeda muddada dheer ee haraaga waxay keeni doontaa khatar ku wajahan deegaanka dabiiciga ah ee biyaha. sidaas darteed diwaangelinteedii si tartiib tartiib ah ayaa loo joojiyay 2013 ee Shiinaha. Waqtigan xaadirka ah, isticmaalkeeda Shiinaha waa la mamnuucay, laakiin wali si weyn ayaa looga isticmaalaa suuqyada caalamiga ah, waxayna wali sii wadi kartaa diiwaangelinta dhoofinta Shiinaha. Maraykanka iyo Brazil waa labada suuq ee ugu sarreeya dhoofinta methasulfuron methyl ee Shiinaha.
sifooyinka jirka iyo kiimikaad
Daroogada farsamadu waa cad, adag oo aan ur lahayn, oo leh bar dhalaalaysa 163 ℃ 166 ℃ iyo cadaadiska uumiga 7.73 × 10-3 Pa/25 ℃. Biyuhu waxay ku kala duwan yihiin pH: 270 at pH 4.59, 1750 at pH 5.42, and 9500 mg/L at pH 6.11.
Sunta
Sunta ku jirta xayawaanka dhiigga diirran aad bay u yar tahay. LD50-ka afka ee jiirka ayaa ka badan 5000 mg/kg, iyo sunta xayawaanka biyuhu waa yar tahay. Isticmaalkeeda baahsan waxay ka tagi doontaa tiro badan oo hadhaaga ah ee ciidda, taas oo khatar ku noqon doonta deegaanka deegaanka biyaha, sida hoos u dhigista cufnaanta unugyada Anabaena flosaquae, kaas oo leh xannibaad weyn oo ku saabsan synthase acid acetyllactic (ALS) ee Anabaena. flosaquae.
Farsamaynta waxqabadka
Metsulfuron methyl waxaa inta badan loo isticmaalaa in lagu xakameeyo haramaha caleen-balaadhan ee beeraha qamadiga ah, waxa kale oo ay xakamayn kartaa qaar ka mid ah haramaha cawska ah. Waxaa inta badan loo isticmaalaa daawaynta ciidda ka hor seedling ama stem seedling ka dib iyo buufin caleen. Habka ugu muhiimsan ee ficilku waa in ka dib marka la nuugo unugyada dhirta, waxay si dhakhso ah u dhaqmi kartaa kor iyo hoos ee jidhka dhirta, waxay joojin kartaa dhaqdhaqaaqa acetolactate synthase (ALS), ka hortagga biosynthesis ee acids amino lagama maarmaanka ah, waxay joojisaa qaybta unugyada iyo koritaanka. ka dhig geedo cagaar ah, necrosis dhibic koritaanka, caleen jilbaha, ka dibna si tartiib ah u beero engegan, taas oo ammaan u ah sarreenka, shaciir, miro iyo dalagyada kale ee sarreenka.
Xarunta ugu weyn
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% + qabiilkanuron-methyl 25%
metsulfuron-methyl 6.8% + thifensulfuron-methyl 68.2%
Habka synthetic
Waxaa laga diyaariyey dhexdhexaadkeeda muhiimka ah, methyl phthalate benzene sulfonyl isocyanate (qaab isku mid ah sida bensulfuron methyl), 2-amino-4-methyl-6-methoxy-triazine iyo dichloroethane, ka dib falcelinta heerkulka qolka, shaandhaynta iyo burburka.
Wadamada dhoofinta waaweyn
Marka loo eego xogta kastamka, dhoofinta Shiinuhu ee metsulfuron methyl sanadka 2019 waxay dhan tahay 26.73 milyan oo doolar, kaas oo Maraykanku uu ahaa bartilmaameedka ugu weyn ee suuqa metsulfuron methyl, iyada oo wadarta guud ee la soo dhoofiyo 4.65 milyan oo doolar 2019, Brazil ayaa ahayd suuqa labaad ee ugu weyn, iyadoo soo dejinta ee ku saabsan 3.51 million dollars 2019, Malaysia waxay ahayd suuqa saddexaad ee ugu weyn, iyo soo dejinta 3.37 million dollars 2019. Indonesia, Colombia, Australia, New Zealand, India, Argentina iyo dalal kale ayaa sidoo kale muhiim u ah soo dejinta methyl sulfuron.
