Lambda-cyhalothrin TC

Lambda-cyhalothrin, e lauiloa foi o le cyhalothrin ma le kungfu cyhalothrin, na atiina ae ma le manuia e le AR Jutsum team i le 1984. O lona faiga o le gaioiga o le suia lea o le permeability o le membrane nerve iniseti, faʻalavelaveina le faʻaogaina o le axon nerve iniseti, faʻaumatia le galuega neuron e ala i le fegalegaleai ma le sodium ion channel, faia le iniseti oona ma tuʻituʻi vave i lalo ma mafai ona tuʻituʻi i lalo. 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 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 a le aufaasālalau, i le aso 7 o Me, 2022, i le taimi i le lotoifale, o se fale gaosi oloa a Initia agrochemical company Bharat Rasayan, lea e masani ona gaosia oloa pyrethroid ma isi mea faʻapitoa, na mu ina ua maeʻa le pa.

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 o le ether aldehydes, o le aʻafiaga i luga o le maketi i totonu o le atunuʻu e laʻititi, ma e manaʻomia tele le gauai atu i le faʻatau atu talu ai nei.
