Lambda-cyhalothrin, izwi kandi nka cyhalothrin na kungfu cyhalothrin, yatunganijwe neza nitsinda rya AR Jutsum mu 1984. Uburyo bwayo bwo gukora ni uguhindura uburyo bwo kwanduza udukoko twangiza udukoko, kubuza gutwara imitsi y’udukoko twangiza, gusenya imikorere ya neuron mu gukorana hamwe n'umuyoboro wa sodium ion, kora udukoko twanduye uburozi bukabije, kumugara no gupfa, kandi birashobora guhita bikubita udukoko.Lambda-cyhalothrin ifite ibiranga udukoko twinshi twica udukoko, ibikorwa byinshi nigihe kirekire cyingaruka, kandi birakwiriye kurwanya udukoko twangiza imyaka nkingano, ibigori, ibiti byimbuto, ipamba, imboga zibisi, nibindi.
1 Ibintu by'ibanze

Imiterere y'ibicuruzwa irerekanwa mu gishushanyo 1.
Igishushanyo 1 Imiterere yuburyo bwa beta-cyhalothrin
2 Uburozi no kugenzura intego
Beta-cyhalothrin ifite guhura kwica ningaruka zuburozi bwigifu, kandi ifite ningaruka zimwe zo kwirinda kandi nta ngaruka zifatika.Ifite ingaruka nziza zo kurwanya udukoko twangiza umunwa nka Lepidoptera larvae hamwe ninyenzi zimwe na zimwe za Coleoptera, kandi birashobora no gukoreshwa muguhashya udukoko twangiza umunwa nka pearl psyllium.Ibintu nyamukuru bigenzura beta-cyhalothrin ni midges, inzoka zingabo, zangiza ibigori, inzoka zo mu bwoko bwa beterave, inzoka zo mu mutima, amababi y’ibibabi, inzoka zo mu bwoko, ibinyugunyugu byera, inzoka zo mu mbuto, inzoka zo mu bwoko bwa pamba, inzoka zitukura, imyumbati n’izindi zumye. ibihingwa, birashobora gukumira no kugenzura ibyatsi, nibindi. Koresha ibihe mu turere dutandukanye kwisi: Ubushinwa, cyane cyane kuva muri Werurwe kugeza Kanama;Amerika y'Amajyepfo / Amajyaruguru, kuva muri Werurwe kugeza Gicurasi na Nzeri kugeza Ukuboza;Aziya y'Amajyepfo y'Uburasirazuba, kuva Ukuboza kugeza Gicurasi;Uburayi, kuva muri Werurwe kugeza Gicurasi na Nzeri kugeza Ukuboza ukwezi.
3 Synthesis inzira hamwe nabahuza nyamukuru
(1) Synthesis ya trifluorochlorochrysanthemum aside chloride
Acide ya Trifluorochlorochrysanthemum (Kung fu aside) ikora na thionyl chloride, desolubilize kandi ikosora kugirango ibone chloride trifluorochlorochrysanthemic.
(2) Synthesis ya chlorofluorocyanide yamavuta ya peteroli
Chlorofluroyl chloride, m-phenoxybenzaldehyde (ether aldehyde) na sodium cyanide ikomatanyirizwa hamwe kugirango ibone amavuta ya chlorofluorocyanide yakozwe na catalizator.
(3) Synthesis ya beta-cyhalothrin
Ibikorwa bya amine kama, chlorofluorocyanide ya chorofluorocyanide ikorerwa epimerisation kugirango itange beta-cyhalothrin.
4 Isoko ryimbere mu gihugu
Nk’uko ikibazo cy’urusobe rw’amakuru yica udukoko mu Bushinwa kibitangaza, kugeza ku ya 20 Gicurasi 2022, umubare wa alpha-cyhalothrin wiyandikishije mu bya tekiniki wari 45, naho abiyandikishije ni 81%, 95%, 97%, 96%, na 98%.Muri byo, kwiyandikisha hamwe 95%, 96%, na 98% birimo byari byinshi.
Dukurikije ikibazo cy’urusobe rw’amakuru y’udukoko twangiza udukoko, guhera ku ya 20 Gicurasi 2022. Amakuru yo kwiyandikisha mu gihugu y’imyiteguro ya beta-cyhalothrin yerekana ko hari imvange imwe, muri yo 621 ikaba ari imwe kandi 216 ikomatanya.Igipimo kimwe: 621 yiyandikishije, imyiteguro nyamukuru ni 2.5%, 2.7%, 5%, 25g / L microemuliyoni, 5%, 10%, 25g / L, 2,5% emulioni yamazi, 5%, 2.5%, 25% g / L , 50 g / L EC, 25%, 10%, 2,5% WP, 2,5%, 10%, 25 g / L ihagarikwa rya microcapsule, nibindi. Phoxim, Triazophos, Dextromethrin, Pymetrozine nibindi bicuruzwa bivanze.Ifishi nyamukuru ya dosiye ni: 2%, 3%, 5%, 10%, 22%, 44% emulsique yamazi, 16%, 20%, 25%, 26% EC, 15%, 22%, 30% bahagarika agent, 2%, 5%, 10%, 12%, 30% microemuliyoni, 2%, 4% granules, 4.5%, 22%, 24%, 30% ifu yanduye, nibindi.
5 Amasoko yo hanze
5.1 Kwiyandikisha imyiteguro yo hanze
Ingano nyamukuru imwe yanditswe ni 25 g / L, 50 g / L, 2.5% EC, 2.5%, 10% WP.
Imvange nyamukuru ni: beta-cyhalothrin 9.4% + thiamethoxam 12,6% ihagarikwa rya microcapsule, beta-cyhalothrine 1.7% + abamectin 0.3% EC, thiamethoxam 14.1% + ikora neza cyane chlorofluorocarbon Cypermethrin 10.6% ihagarika, Acetamiprid 2% + Beta-cyhal % EC.
5.2 Ibyoherezwa mu Bushinwa
Kuva mu 2015 kugeza 2019, ibigo 582 byohereje mu mahanga ibicuruzwa byiza bya tekiniki na cyhalothrin byo mu rwego rwo hejuru, kandi ibicuruzwa byoherezwa mu mahanga icumi bya mbere byari 45% by’ibicuruzwa byoherezwa mu mahanga (gukusanya imyaka 5).Ibigo icumi bya mbere biri ku mbonerahamwe ya 2.
Ikigereranyo cyo kohereza mu mahanga ibikoresho bya tekiniki ni toni 2,400 / umwaka, naho ibicuruzwa byoherezwa mu mahanga ni toni 3.000 / umwaka.Ibicuruzwa byoherezwa mu mahanga byiyongereye uko umwaka utashye kuva 2015 kugeza 2019. Ikigereranyo cyo kohereza mu mahanga imyiteguro y’umubiri ni toni 14.800 / umwaka, naho ibicuruzwa byoherezwa mu mahanga ni toni 17.000 (2017), hanyuma ibicuruzwa byoherezwa mu mahanga bikaba bihamye;impuzandengo yo kohereza ibicuruzwa hanze ni toni 460 / umwaka, naho hejuru ni toni 515 / umwaka.
Kuva mu 2015 kugeza 2019, ibicuruzwa bya tekiniki no gutegura cyhalothrin byoherejwe ku masoko 77.Amasoko atanu ya mbere ni Amerika, Ububiligi, Ubuhinde, Arijantine, na Pakisitani.Amasoko atanu ya mbere yari afite 57% by’Ubushinwa bwohereza ibicuruzwa hanze.(Imyaka 5 yuzuye).
6 Ibigezweho ku isoko
Nk’uko amakuru aturuka mu bitangazamakuru abitangaza, ku ya 7 Gicurasi 2022, ku isaha yaho, uruganda rw’isosiyete ikora ibijyanye n’ubuhinzi bw’ubuhinde Bharat Rasayan, rukora cyane cyane ibicuruzwa bya pyrethroide n’abunzi bayo bifitanye isano, byafashwe n’umuriro nyuma yo guturika.
Ubuhinde ni kimwe mu bintu by’udukoko twangiza udukoko twangiza udukoko twangiza udukoko ku isi, muri byo hakaba harimo ubushobozi bw’umusaruro w’ibanze hagati y’ibicuruzwa bya pyrethroide, methyl betinate na ether aldehyde, biri hejuru cyane.Mu 2021, Bharat Rasayan azohereza hanze toni zirenga 6.000 z'imiti yica udukoko twica udukoko, imyiteguro n’abahuza, muri bo 61% ni imiti ya tekiniki, 13% itegura na 26% (cyane cyane abahuza pyrethroide).Nkurwego rwingenzi rwo guhuza imiti yica udukoko twa pyrethroide, ether aldehyde ikenera buri mwaka imbere mu gihugu ingana na toni zigera ku 6.000, muri zo hafi kimwe cya kabiri kigomba kugurwa mu Buhinde.
Kubera ko isoko ryimbere muri cyhalothrin riri hafi kurangira, kandi isosiyete yo mubuhinde ntabwo aricyo kigo nyamukuru gitanga alpha-cyhalothrin ihuza abahuza nka ether aldehydes, ingaruka ku isoko ryimbere ni nto, kandi ni ngombwa cyane kwishyura kwitondera ibyoherezwa hanze.Amagambo.
