Lambda-cyhalothrin TC

Lambda-cyhalothrin, e lauiloa foi o le cyhalothrin ma le kungfu cyhalothrin, na faʻaleleia lelei e le AR Jutsum team i le 1984. O lona faiga o le gaioiga o le suia lea o le faʻaogaina o le membrane nerve iniseti, faʻalavelaveina le faʻaogaina o le axon nerve iniseti, faʻaumatia le galuega neuron e ala i le fegalegaleai. fa'atasi ai ma le alavai o le sodium ion, fa'aoso le iniseti o'ona e so'ona fiafia, pipili ma pe, ma e mafai ona vave tu'i i lalo le fa'ama'i.Lambda-cyhalothrin o loʻo i ai uiga o le lautele insecticidal spectrum, maualuga le gaioiga ma le umi o le aʻafiaga, ma e talafeagai mo faʻamaʻi faʻamaʻi o fualaʻau e pei o saito, sana, fualaau aina, cotton, cruciferous vegetables, etc.

Mai le 2015 i le 2019, o le aofaʻi o kamupani e 582 na faʻatau atu oloa faʻatekonolosi ma sauniuniga sili ona lelei, ma o le aofaʻi o oloa auina atu i fafo o kamupani e sefulu pito i luga na maua ai le 45% o le aofaʻi o le faʻaulufaleina (5-tausaga faʻaputuga).O kamupani pito i luga e sefulu o loʻo lisiina ile Laulau 2.

O le averesi o le auina atu i fafo o mea faʻapitoa e 2,400 tone / tausaga, ma o le maualuga o le faʻatau atu o oloa e 3,000 tone / tausaga.Ua si'itia le aofa'i o oloa auina atu i fafo mai lea tausaga i lea tausaga mai le 2015 i le 2019. O le averesi o le auina atu i fafo o tapenaga faaletino e 14,800 tone/tausaga, ma le maualuga o le oloa e auina atu i fafo e 17,000 tone (2017), ona mautu ai lea o le tele o oloa auina atu i fafo;o le averesi o le tele o tapenaga e auina atu i fafo e 460 tone/tausaga, ma le maualuga e 515 tone/tausaga.

Mai le 2015 i le 2019, o oloa faʻapitoa ma sauniuniga o le cyhalothrin na faʻatau atu i maketi e 77.O maketi pito i luga e lima o le Iunaite Setete, Peleseuma, Initia, Atenitina, ma Pakisitana.O maketi pito i luga e lima na maua ai le 57% o le aofaʻi o oloa auina atu i fafo a Saina.(5 tausaga fa'aopoopo).

6 Tulaga fou o maketi

E tusa ai ma faʻamatalaga faʻasalalau, i le aso 7 o Me, 2022, taimi faʻapitonuʻu, o se fale gaosi oloa a Initia agrochemical kamupani Bharat Rasayan, lea e tele lava ina gaosia oloa pyrethroid ma isi fesoʻotaʻiga, na mu ina ua maeʻa le paʻu.

O Initia o se tasi o kamupani tele e leai ni pateni e gaosia ai vailaau faʻasaina i le lalolagi, o loʻo i ai le gafatia o le gaosiga o mea autu o mea tau pyrethroid, methyl betinate ma ether aldehyde, e maualuga tele.I le 2021, Bharat Rasayan o le a auina atu i fafo le aofaʻi o le sili atu i le 6,000 tone o vailaʻau faʻapitoa faʻamaʻi, sauniuniga ma mea faʻapitoa, lea e 61% o vailaʻau faʻapitoa, 13% sauniuniga ma 26% intermediates (tele pyrethroid intermediates).I le avea ai o se vaega taua mo le faʻapipiʻiina o vailaau faʻamaʻi pyrethroid, eter aldehyde o loʻo i ai le manaʻoga faʻaletausaga faaletausaga e tusa ma le 6,000 tone, lea e toeitiiti atoa le afa e manaʻomia ona faʻatau mai Initia.

Talu ai o le maketi i totonu o le atunuʻu mo cyhalothrin ua latalata i lona iuga, ma o le kamupani Initia e le o le atinaʻe autu lea e gaosia ai le alpha-cyhalothrin-related intermediates e pei ole ether aldehydes, o le aʻafiaga i luga o maketi i totonu o le atunuʻu e laʻititi lava, ma e manaʻomia tele le totogiina. gauai atu i le auina atu i fafo talu ai nei.Upusii.
