I-Metsulfuron methyl, isibulala-zinambuzane sikakolo esisebenza kahle kakhulu esakhiwa i-DuPont ekuqaleni kwawo-1980, ingeye-sulfonamides futhi inobuthi obuphansi kubantu nasezilwaneni. Isetshenziselwa kakhulu ukulawula ukhula lwamaqabunga abanzi, futhi inomphumela omuhle wokulawula ukhula oluthile lwe-gramineous. Ingakwazi ukuvimbela ngempumelelo futhi ilawule ukhula emasimini kakolweni, njenge-Mainiang, Veronica, Fanzhou, Chaocai, isikhwama somalusi, isikhwama somalusi esiphukile, i-Soniang Artemisia annua, i-albhamu ye-Chenopodium, i-Polygonum hydropiper, i-Oryza rubra, ne-Arachis hypogaea.
Umsebenzi wayo uphindwe izikhathi ezingu-2-3 kune-chlorsulfuron methyl, futhi ifomu layo eliyinhloko lokulinganisa umthamo ukumiswa okomile noma impushana emanzi. Kodwa-ke, ngenxa yokusebenza kwayo okuphezulu, ukubulawa kokhula okubanzi, ukuqina okuqinile, kanye nokusetshenziswa okubanzi emhlabeni, ishiya inani elikhulu lezinsalela emhlabathini, futhi umphumela wayo osalayo wesikhathi eside uzobeka usongo endaweni ezungezile yasemanzini, ngakho-ke ukubhaliswa kwayo kuye kwakhanselwa kancane kancane ngo-2013 e-China. Njengamanje, ukusetshenziswa kwayo e-China kuvinjelwe, kodwa isasetshenziswa kabanzi emakethe yamazwe ngamazwe, futhi isengakwazi ukubamba ukubhaliswa kokuthekelisa eChina. I-United States neBrazil izimakethe ezimbili ezihamba phambili zokuthekelisa ze-methasulfuron methyl e-China.
Izakhiwo zomzimba namakhemikhali
Umuthi wobuchwepheshe uqinile omhlophe, ongenaphunga, onephuzu lokuncibilika elingu-163 ～ 166 ℃ kanye nomfutho womhwamuko ongu-7.73 × 10-3 Pa/25 ℃. Ukunyibilika kwamanzi kuyahlukahluka nge-pH: 270 ku-pH 4.59, 1750 ku-pH 5.42, kanye no-9500 mg/L ku-pH 6.11.
Ubuthi
Ubuthi ezilwaneni ezinegazi elifudumele buphansi kakhulu. I-LD50 yomlomo yamagundane ingaphezu kuka-5000 mg/kg, kanti ubuthi ezilwaneni zasemanzini buphansi. Ukusetshenziswa kwayo kabanzi kuzoshiya inqwaba yezinsalela enhlabathini, okuzoba usongo endaweni ezungezile yasemanzini, njengokunciphisa ukuminyana kwamaseli e-Anabaena flosaquae, enokuvimbela okuphawulekayo ku-acetyllactic acid synthase (ALS) yase-Anabaena. i-flosaquae.
Indlela yokwenza
I-Metsulfuron methyl isetshenziswa kakhulu ukulawula ukhula olunamaqabunga abanzi emasimini kakolweni, futhi ingalawula nokhula oluthile lwe-gramineous. Isetshenziselwa ikakhulukazi ukwelashwa kwenhlabathi yangaphambi kwezithombo noma isiqu sesithombo kanye nesifutho samaqabunga. Indlela eyinhloko yokwenza ukuthi ngemva kokumuncwa izicubu zezitshalo, ingaqhuba ngokushesha phezulu naphansi emzimbeni wesitshalo, ivimbele umsebenzi we-acetolactate synthase (ALS), ivimbele i-biosynthesis yama-amino acid abalulekile, ivimbele ukuhlukana kwamaseli nokukhula, yenza izithombo zibe luhlaza, i-growth point necrosis, amaqabunga abune, bese utshala kancane kancane ebuna, okuphephile ukolweni, ibhali, oats nezinye izitshalo zikakolweni.
Inhlanganisela eyinhloko
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
i-mesulfuron-methyl 25% + trinuron-methyl 25%
metsulfuron-methyl 6.8% + thifensulfuron-methyl 68.2%
Inqubo yokwenziwa
Ilungiswa kusuka ku-intermediate yayo ebalulekile, i-methyl phthalate benzene sulfonyl isocyanate (indlela efanayo yokuhlanganisa njenge-bensulfuron methyl), i-2-amino-4-methyl-6-methoxy-triazine kanye ne-dichloroethane, ngemva kokusabela ekamelweni lokushisa, ukuhluzwa kanye nokuchithwa.
Amazwe amakhulu athumela ngaphandle
Ngokusho kwedatha yamasiko, ukuthengiswa kwe-metsulfuron methyl eChina ngo-2019 kwafinyelela cishe ezigidini ezingama-26.73 zamaRandi, lapho i-United States yayiyimakethe enkulu kunazo zonke ehlosiwe ye-metsulfuron methyl, kanye nokungeniswa kwamanye amazwe kwezigidi ezingama-4.65 zamadola ngo-2019, iBrazil bekuyimakethe yesibili ngobukhulu, ukungeniswa kwamanye amazwe cishe kwezigidi ezingu-3.51 zamaRandi ngo-2019, iMalaysia yayiyimakethe yesithathu ngobukhulu, futhi ukuthengiswa kwamanye amazwe kwezigidi ezingu-3.37 zamadola ngo-2019. I-Indonesia, i-Colombia, i-Australia, i-New Zealand, i-India, i-Argentina namanye amazwe nawo abalulekile abangenisa i-methyl sulfuron.
