Ko te Metsulfuron methyl, he patupatu witi tino whai hua i hangaia e DuPont i te timatanga o te 1980s, no nga sulfonamides he iti te paitini ki te tangata me nga kararehe. Ka whakamahia te nuinga ki te whakahaere i nga taru rau whanui, a he pai te mana whakahaere ki etahi taru karama. Ka taea e ia te aukati me te whakahaere i nga taru i roto i nga mara witi, penei i a Mainiang, Veronica, Fanzhou, Chaocai, putea hepara, putea hepara pakaru, Soniang Artemisia annua, Chenopodium album, Polygonum hydropiper, Oryza rubra, me Arachis hypogaea.
Ko tana mahi he 2-3 nga wa o te chlorsulfuron methyl, a ko tana puka inenga tukatuka matua ko te whakatārewatanga maroke, te paura wettable ranei. Heoi, na te nui o te mahi, te nui o te patu taru, te kaha o te whai whakaaro, me te whanuitanga o te whakamahinga ki te ao, ka waiho he maha o nga toenga ki te oneone, a, ko te roanga o te toenga ka waiho hei riri mo te taiao kaiao wai. no reira kua whakakorea tona rehitatanga i te tau 2013 i Haina. I tenei wa, kua whakakorehia te whakamahi i Haina, engari kei te whakamahia tonu i te maakete o te ao, ka taea tonu te pupuri i te rehitatanga kaweake ki Haina. Ko te United States me Brazil nga maakete kaweake e rua o te methasulfuron methyl i Haina.
Ngā āhuatanga ā-tinana me te matū
Ko te rongoa hangarau he ma, he toka kore kakara, he 163 ～ 166 ℃ te ira whakarewa me te pehanga kohu 7.73 × 10-3 Pa/25 ℃. He rereke te wairewa ki te pH: 270 i te pH 4.59, 1750 i te pH 5.42, me te 9500 mg/L i te pH 6.11.
Te paitini
He iti rawa te paitini ki nga kararehe toto whakamahana. Ko te LD50-waha o nga kiore he nui ake i te 5000 mg/kg, he iti te paitini ki nga kararehe wai. Ko tana whakamahinga whanui ka waiho he maha o nga toenga i roto i te oneone, ka waiho hei whakatuma mo te taiao kaiao wai, penei i te whakaheke i te kiato o nga pūtau o Anabaena flosaquae, he nui te aukati i te acetyllactic acid synthase (ALS) o Anabaena. flosaquae.
Te tikanga mahi
Ko te Metsulfuron methyl te nuinga o te whakamahi ki te whakahaere i nga taru whaanui i roto i nga mara witi, ka taea hoki te whakahaere etahi taru karu. Ka whakamahia te nuinga mo te maimoatanga o te oneone i mua i te tipu, i te kakau ranei i muri i te tipu me te rehu rau. Ko te tikanga matua o te mahi ko te mea i muri i te whakaurunga o nga kopa tipu, ka taea e ia te whakahaere tere me te heke i roto i te tinana o te tipu, te aukati i te mahi o te acetolactate synthase (ALS), te aukati i te biosynthesis o nga waikawa amino tino, te aukati i te wehenga pūtau me te tipu, kia kaakaaka nga tipu, ka mate te tipu, ka maroke nga rau, katahi ka maroke haere te whakato, he pai mo te witi, parei, oati me etahi atu hua witi.
Pūhui matua
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%
Te tukanga waihanga
Kua whakaritea mai i tana takawaenga nui, te methyl phthalate benzene sulfonyl isocyanate (he rite te tikanga whakahiato me te bensulfuron methyl), 2-amino-4-methyl-6-methoxy-triazine me te dichloroethane, i muri i te tauhohenga i te pāmahana rūma, te tātari me te whakakorenga.
Nga whenua kaweake nui
E ai ki nga korero mo nga tikanga, ko nga kawemai a Haina o te metsulfuron methyl i te tau 2019 tata ki te 26.73 miriona taara, ko te United States te maakete nui rawa atu o te metsulfuron methyl, me te kawemai i te 4.65 miriona taara i te tau 2019, ko Brazil te tuarua o nga maakete nui rawa atu, me te Ko nga kawemai mo te 3.51 miriona taara i te 2019, ko Malaysia te tuatoru o nga maakete nui rawa atu, me te kawemai i te 3.37 miriona taara i te tau 2019. Ko Indonesia, Colombia, Ahitereiria, Aotearoa, Inia, Argentina me etahi atu whenua he kawemai nui o te methyl sulfuron.
