Metsulfuron methyl, ibyatsi byangiza cyane byakozwe na DuPont mu ntangiriro ya za 1980, ni ibya sulfonamide kandi bifite uburozi buke ku bantu no ku nyamaswa. Ikoreshwa cyane cyane mu kurwanya ibyatsi bibi, kandi bigira ingaruka nziza zo kurwanya ibyatsi bibi. Irashobora gukumira no kurwanya nyakatsi mu murima w'ingano, nka Mainiang, Veronica, Fanzhou, Chaocai, agasakoshi k'umwungeri, isakoshi y'abashumba yamenetse, Soniang Artemisia annua, Album ya Chenopodium, hydropiper Polygonum, Oryza rubra, na Arachis hypogaea.
Igikorwa cyacyo cyikubye inshuro 2-3 za methyl ya chlorsulfuron, kandi uburyo nyamukuru bwo gutunganya dosiye ni ihagarikwa ryumye cyangwa ifu yuzuye. Nyamara, kubera ibikorwa byayo byinshi, kwica nyakatsi nyinshi, kugira uruhare rukomeye, no gukoreshwa henshi ku isi, isiga umubare munini w’ibisigara mu butaka, kandi ingaruka zayo z'igihe kirekire zizabangamira ibidukikije by’amazi, kwiyandikisha kwayo rero kwagiye guhagarikwa buhoro buhoro muri 2013 mu Bushinwa. Kugeza ubu, ikoreshwa ryayo mu Bushinwa ryarabujijwe, ariko riracyakoreshwa henshi ku isoko mpuzamahanga, kandi rirashobora kwandikisha ibicuruzwa byoherezwa mu Bushinwa. Amerika na Berezile nibyo bihugu bibiri bya mbere byohereza ibicuruzwa bya methasulfuron methyl mu Bushinwa.
Imiterere yumubiri nubumara
Umuti wa tekiniki ni umweru, udafite impumuro nziza, ufite aho ushonga ya 163 ～ 166 ℃ hamwe n’umuvuduko wumwuka wa 7,73 × 10-3 Pa / 25 ℃. Amazi ashobora guhinduka hamwe na pH: 270 kuri pH 4.59, 1750 kuri pH 5.42, na 9500 mg / L kuri pH 6.11.
Uburozi
Uburozi bwinyamaswa zishyushye ni buke cyane. LD50 yo mu kanwa yimbeba zirenga 5000 mg / kg, kandi uburozi bwinyamaswa zo mu mazi ni buke. Ikoreshwa ryinshi rizasiga umubare munini w’ibisigisigi mu butaka, bizabangamira ibidukikije by’amazi, nko kugabanya ubwinshi bw’utugingo ngengabuzima twa Anabaena flosaquae, bufite aho bihurira cyane na synthase ya acetyllactique (ALS) ya Anabaena flosaquae.
Uburyo bwibikorwa
Metsulfuron methyl ikoreshwa cyane cyane muguhashya ibyatsi-amababi yagutse mu murima w ingano, kandi irashobora no kurwanya nyakatsi zimwe na zimwe. Ikoreshwa cyane mugutunganya imbuto mbere yo gutera cyangwa gutera ingemwe zatewe no gutera amababi. Uburyo nyamukuru bwibikorwa ni uko nyuma yo kwinjizwa nuduce twibimera, irashobora kwihuta hejuru no hepfo mumubiri wibimera, ikabuza ibikorwa bya synthase ya acetolactate (ALS), ikabuza biosynthesis ya acide ya amine yingenzi, ikabuza kugabana selile no gukura, kora ingemwe icyatsi, aho gukura necrosis, guhanagura amababi, hanyuma utere buhoro buhoro, bikaba bifite ingano, ingano, sayiri, oati nibindi bihingwa byingano.
Urwego nyamukuru
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%
Inzira yubukorikori
Yateguwe kuva murwego rwayo rwagati, methyl phthalate benzene sulfonyl isocyanate (uburyo bumwe bwo guhuza nka methyl ya bensulfuron), 2-amino-4-methyl-6-mikorerexy-triazine na dichloroethane, nyuma yo kubyitwaramo mubushyuhe bwicyumba, kuyungurura no gusenya.
Ibihugu bikomeye byohereza ibicuruzwa hanze
Nk’uko imibare ya gasutamo ibigaragaza, mu Bushinwa byohereje methyl sulfur methyl mu mwaka wa 2019 byose hamwe byinjije miliyoni 26.73 z'amadolari, muri yo Amerika ikaba ari yo soko nini yagenewe methyl sulfuron, aho ibicuruzwa byatumijwe mu mahanga miliyoni 4.65 muri 2019, Burezili ni ryo soko rya kabiri rinini, hamwe na ibicuruzwa bitumizwa mu mahanga bigera kuri miliyoni 3.51 z'amadolari muri 2019, Maleziya yari isoko rya gatatu rinini, naho ibicuruzwa byatumijwe mu mahanga miliyoni 3.37 muri 2019. Indoneziya, Kolombiya, Ositaraliya, Nouvelle-Zélande, Ubuhinde, Arijantine n'ibindi bihugu na byo ni byo bitumiza methyl sulfuron.
