Kugereranya hagati ya Dimethalin nabanywanyi
Dimethylpentyl ni herbicide ya dinitroaniline. Yinjizwa cyane cyane nuduti twatsi tumera kandi igahuzwa na poroteyine ya microtubule mu bimera kugirango ibuze mitito yingirabuzimafatizo, bikaviramo gupfa. Ikoreshwa cyane muburyo bwinshi bwimirima yumye, harimo ipamba nibigori, no mumirima yumuceri yumye. Ugereranije nibicuruzwa birushanwe acetochlor na trifluralin, dimethalin ifite umutekano mwinshi, ibyo bikaba bijyanye nicyerekezo rusange cyiterambere ryumutekano wica udukoko, kurengera ibidukikije nuburozi buke. Biteganijwe ko izakomeza gusimbuza acetochlor na trifluralin mugihe kizaza.
Dimethalin ifite ibiranga ibikorwa byinshi, uburyo bwinshi bwo kwica ibyatsi, uburozi buke n’ibisigara, umutekano muke ku bantu no ku nyamaswa, hamwe n’ubutaka bukomeye bw’ubutaka, ntibyoroshye kumeneka, kandi bitangiza ibidukikije; Irashobora gukoreshwa mbere na nyuma yo kumera na mbere yo guhingwa, kandi igihe cyayo kigera ku minsi 45 ~ 60. Porogaramu imwe irashobora gukemura ibyatsi bibi mugihe cyikura ryibihingwa.
Isesengura kumiterere yiterambere ryinganda dimethalin kwisi
1. Umugabane wibyatsi ku isi
Kugeza ubu, ibyatsi bikoreshwa cyane ni glyphosate, bingana na 18% by’isoko ry’ibyatsi ku isi. Ibimera bya kabiri ni glyphosate, bingana na 3% gusa ku isoko ryisi. Indi miti yica udukoko ifite umubare muto ugereranije. Kuberako glyphosate nindi miti yica udukoko ikora cyane kubihingwa byanduye. Ibyinshi mu byatsi bisabwa kugirango habeho ibindi bihingwa bitari GM bingana na 1%, bityo isoko ry’ibyatsi ni bike. Kugeza ubu, isoko ry’isi yose kuri dimethalin rirenga toni zirenga 40.000, igiciro cyo hagati kikaba kingana na 55.000 yuan / toni, naho kugurisha isoko ni hafi miliyoni 400 z'amadolari, bingana na 1% ~ 2% by’isoko ry’ibyatsi ku isi; igipimo. Kubera ko ishobora gukoreshwa mu gusimbuza ibindi byatsi byangiza mu gihe kiri imbere, biteganijwe ko igipimo cy’isoko kizikuba kabiri kubera umwanya munini w’iterambere.
2. Kugurisha dimethalin
Muri 2019, dimethalin yagurishijwe ku isi yose yari miliyoni 397 z'amadolari y'Amerika, bituma iba iya 12 mu bimera byica ibyatsi ku isi. Ku bijyanye n'uturere, Uburayi ni rimwe mu masoko akomeye y'abaguzi ya dimethalin, angana na 28.47% by'umugabane w'isi; Aziya ifite 27.32%, naho ibihugu nyamukuru bigurisha ni Ubuhinde, Ubushinwa n'Ubuyapani; Amerika yibanda cyane muri Amerika, Burezili, Kolombiya, Ecuador n'ahandi; Uburasirazuba bwo hagati na Afurika bifite ibicuruzwa bito.
Incamake
Nubwo dimethalin igira ingaruka nziza kandi ikangiza ibidukikije, ikoreshwa cyane cyane mubihingwa ngengabukungu nka pamba n'imboga bitewe nigiciro cyinshi muburyo bumwe bwimiti yica ibyatsi no gutangira isoko ryatinze. Hamwe no guhindura buhoro buhoro igitekerezo cyisoko ryimbere mu gihugu, icyifuzo cyo gukoresha dimethalin cyiyongereye vuba. Umubare w’ibiyobyabwenge bibisi bikoreshwa ku isoko ryimbere mu gihugu byiyongereye byihuse kuva kuri toni 2000 muri 2012 kugeza kuri toni zirenga 5000 muri iki gihe, kandi byatejwe imbere kandi bikoreshwa mu muceri wabibwe wumye, ibigori n’ibindi bihingwa. Imvange zitandukanye zivanze neza nazo ziratera imbere byihuse.
Dimethalin ijyanye n’isoko mpuzamahanga ryo gusimbuza buhoro buhoro imiti yica udukoko twangiza kandi twangiza udukoko twangiza ibidukikije. Bizaba bifite urwego rwo hejuru rwo guhuza niterambere ryubuhinzi bugezweho mugihe kizaza, kandi hazaba umwanya munini witerambere.
