Lambda-cyhalothrin, oo sidoo kale loo yaqaan cyhalothrin iyo kungfu cyhalothrin, waxaa si guul leh u soo saaray kooxda AR Jutsum ee 1984. Habka ficilku waa in la beddelo qulqulka xuubka neerfaha cayayaanka, wuxuu joojiyaa habdhiska dareemayaasha cayayaanka, wuxuu burburiyaa shaqada neerfaha iyadoo la falgalayo. kanaalka sodium ion, ka dhig cayayaanka sumaysan mid aad u kacsan, curyaana oo dhinta, oo si dhakhso ah u garaaci kara cayayaanka.Lambda-cyhalothrin waxay leedahay sifooyin cayayaan ballaaran oo cayayaan ah, firfircooni sare iyo muddada dheer ee saamaynta, waxayna ku habboon tahay xakamaynta cayayaanka dalagyada sida sarreenka, galleyda, geedaha miraha, suufka, khudaarta cruciferous, iwm.

5.2 Dhoofinta Shiinaha
Laga soo bilaabo 2015 ilaa 2019, wadar ahaan 582 shirkadood ayaa dhoofiyay alaabada farsamada iyo diyaarinta waxtarka sare leh ee cyhalothrin, iyo mugga dhoofinta ee tobanka shirkadood ee ugu sarreeya waxay ka dhigan tahay 45% wadarta guud ee mugga dhoofinta (ururka 5-sano).Tobanka shirkadood ee ugu sarreeya waxay ku taxan yihiin shaxda 2.
Celceliska mugga dhoofinta agabka farsamada waa 2,400 tan/sanadkii, mugga dhoofinta ugu sarreysana waa 3,000 tan/sanadkii.Mugga dhoofinta ayaa kordhay sannadba sanadka ka 2015 ilaa 2019. Celceliska mugga dhoofinta ee diyaarinta jireed waa 14,800 tan / sannadkii, iyo mugga dhoofinta ugu sarreeya waa 17,000 tan (2017), ka dibna mugga dhoofinta waa mid deggan;celceliska mugga dhoofinta diyaargarowga waa 460 tan / sannadkii, kan ugu sarreeyana waa 515 tan / sannadkii.
Laga soo bilaabo 2015 ilaa 2019, alaabta farsamada iyo diyaarinta ee cyhalothrin ayaa loo dhoofiyay suuqyada 77.Shanta suuq ee ugu sarreeya waxay ahaayeen Maraykanka, Belgium, India, Argentina, iyo Pakistan.Shanta suuq ee ugu sarreeya waxay ahaayeen 57% wadarta guud ee wax-soo-saarka Shiinaha.(Isugeyn 5 sano ah).
6 isbeddellada suuqa ugu dambeeyay
Sida laga soo xigtay ilo-warbaahineed, May 7, 2022, waqtiga maxaliga ah, warshad ay leedahay shirkadda agrochemical Indian Bharat Rasayan, oo inta badan soo saarta alaabada pyrethroid-ka iyo dhexdhexaadiyeyaasha la xidhiidha, ayaa dab qabsaday ka dib qarax kuleyl ah.
Hindiya waa mid ka mid ah kuwa ugu waaweyn ee soo saarayaasha sunta cayayaanka ee aan patent-ka ahayn ee adduunka, oo ay ka mid yihiin awoodda wax-soo-saarka ee dhexdhexaadiyeyaasha muhiimka ah ee alaabta pyrethroid, methyl betinate iyo ether aldehyde, ayaa aad u sarreeya.Sannadka 2021, Bharat Rasayan waxa ay dhoofin doontaa in ka badan 6,000 oo tan oo dawooyinka farsamada sunta cayayaanka lagu dilo, diyaarinta iyo dhex dhexaadinta, kuwaas oo 61% ay yihiin dawooyin farsamo, 13% diyaargarow iyo 26% dhexdhexaadin ah (badanaa pyrethroid intermediates).Dhex dhexaad muhiim ah oo loogu talagalay soo saarista sunta cayayaanka ee pyrethroid, ether aldehyde waxay leedahay baahi sanadle ah oo gudaha ah oo ku saabsan 6,000 tan, taas oo ku dhawaad kalabar u baahan tahay in laga soo iibsado Hindiya.
Maaddaama suuqa gudaha ee cyhalothrin uu ku dhow yahay gebogebo, shirkadda Hindida ma aha shirkadda ugu weyn ee soo saarta dhexdhexaadiyeyaasha alfa-cyhalothrin la xidhiidha sida ether aldehydes, saameynta suuqa gudaha waa mid yar, waxaana inta badan loo baahan yahay in la bixiyo. fiiro gaar ah u dhoofinta dhawaan.Xigasho.
