Protoporphyrinogen oxidase (PPO) waa mid ka mid ah bartilmaameedyada ugu muhiimsan ee horumarinta noocyada cusub ee geedaha lagu buufiyo, taasoo ka dhigan qayb weyn oo suuqa ka mid ah. Maadaama geedkan lagu buufiyo uu inta badan ku shaqeeyo chlorophyll isla markaana uu leeyahay sun yar oo ku dhacda naasleyda, geedkan lagu buufiyo wuxuu leeyahay astaamo waxtar sare leh, sun yar iyo badbaado.
Xayawaanka, dhirta, bakteeriyada iyo fangaska dhammaantood waxay ka kooban yihiin protoporphyrinogen oxidase, kaas oo kiciya protoporphyrinogen IX una beddela protoporphyrin IX iyadoo la raacayo xaalad oksijiin molecular ah, protoporphyrinogen oxidase waa ensaymkii ugu dambeeyay ee caadiga ahaa ee ku jira biosynthesis-ka tetrapyrrole, kaasoo inta badan isku dara heme ferrous iyo chlorophyll. Dhirta, protoporphyrinogen oxidase wuxuu leeyahay laba isoenzymes, kuwaas oo ku yaal mitochondria iyo chloroplasts siday u kala horreeyaan. Protoporphyrinogen oxidase inhibitors waa herbicides xooggan oo xiriir ah, kuwaas oo gaari kara ujeeddada xakamaynta haramaha inta badan iyagoo joojinaya isku-darka midabada dhirta, waxayna leeyihiin muddo gaaban oo harsan oo ciidda ah, taas oo aan waxyeello u lahayn dalagyada dambe. Noocyada cusub ee geedkan sunta ah wuxuu leeyahay astaamo kala-doorasho, firfircooni sare, sun yar iyo aan si fudud loogu ururin karin deegaanka.
Daawooyinka PPO ee noocyada ugu muhiimsan ee geedaha lagu buufiyo
1. Diphenyl ether herbicides
Qaar ka mid ah noocyada PPO ee ugu dambeeyay
3.1 Magaca ISO ee saflufenacil ee la helay 2007 - BASF, shatigu wuxuu dhacay 2021.
Sannadkii 2009, benzochlor waxaa markii ugu horreysay laga diiwaan geliyay Mareykanka waxaana la suuq geeyay sannadkii 2010. Benzochlor hadda waxaa laga diiwaan geliyay Mareykanka, Kanada, Shiinaha, Nicaragua, Chile, Argentina, Brazil iyo Australia. Waqtigan xaadirka ah, shirkado badan oo Shiinaha ku yaal ayaa ku jira diiwaangelinta.
3.2 Wuxuu ku guuleystay magaca ISO ee tiafenacil sanadkii 2013, shatiguna wuxuu dhacayaa sanadka 2029.
Sannadkii 2018, flursulfuryl ester ayaa markii ugu horreysay laga bilaabay Kuuriyada Koonfureed; Sannadkii 2019, waxaa laga bilaabay Sri Lanka, taasoo furtay safarka lagu xayeysiinayo badeecada suuqyada dibadda. Waqtigan xaadirka ah, flursulfuryl ester waxaa sidoo kale laga diiwaan geliyay Australia, Mareykanka, Kanada, Brazil iyo dalal kale, waxaana si firfircoon looga diiwaan geliyay suuqyo kale oo waaweyn.
3.3 Magaca ISO trifludimoxazin (trifluoxazin) waxaa la helay 2014, shatiguna wuxuu dhacayaa 2030.
Maajo 28, 2020, dawadii asalka ahayd ee trifluoxazine ayaa laga diiwaan geliyay Australia markii ugu horreysay adduunka, habka ganacsiga caalamiga ah ee trifluoxazine-na si degdeg ah ayuu u horumaray, Luulyo 1-deedii isla sanadkaasna, badeecada isku-dhafka ah ee BASF (125.0g /L tricfluoxazine + 250.0g /L benzosulfuramide suspension) ayaa sidoo kale loo ansixiyay diiwaangelinta Australia.
3.4 Magaca ISO ee cyclopyranil oo la helay 2017 - shatigu wuxuu dhacayaa 2034.
Shirkad Jabbaan ah ayaa codsatay shati Yurub ah (EP3031806) oo loogu talagalay isku-darka guud, oo ay ku jirto isku-darka cyclopyranil, waxayna soo gudbisay codsi PCT ah, daabacaad caalami ah oo lambarkeedu yahay WO2015020156A1, oo taariikhdeedu ahayd Agoosto 7, 2014. Shatiga waxaa laga oggolaaday Shiinaha, Australia, Brazil, Talyaaniga, Japan, Kuuriyada Koonfureed, Ruushka, iyo Mareykanka.
3.5 epyrifenacil oo la guddoonsiiyay magaca ISO sanadkii 2020
Epyrifenacil oo leh saameyn degdeg ah, oo inta badan loo isticmaalo galleyda, qamadiga, shaciirka, bariiska, hadhuudhka, soybean, cudbi, xididdo sonkor ah, lawska, gabbaldayaha, kufsiga, ubaxyada, dhirta qurxinta, khudaarta, si looga hortago haramaha badan ee caleenta ballaaran iyo haramaha cawska, sida setae, cawska lo'da, cawska beerta, cawska rye, cawska dabada iyo wixii la mid ah.
3.6 ISO waxaa loogu magac daray flufenoximacil (Flufenoximacil) sanadkii 2022
Fluridine waa daawo ka hortagta cayayaanka ee PPO oo leh noocyo badan oo haramaha ah, heer degdeg ah oo ficil ah, wax ku ool ah isla maalinta la isticmaalo, iyo dabacsanaan wanaagsan oo loogu talagalay dalagyada soo socda. Intaa waxaa dheer, fluridine sidoo kale waxay leedahay firfircooni aad u sareysa, taasoo yaraynaysa xaddiga maaddooyinka firfircoon ee haramaha cayayaanka dila ilaa heerka garaam, kaas oo deegaanka u fiican.
Bishii Abriil 2022, fluridine waxaa laga diiwaan geliyay Cambodia, waana liiskeedii ugu horreeyay ee adduunka oo dhan. Badeecada ugu horreysa ee ka kooban maaddadan asaasiga ah waxaa lagu taxayaa Shiinaha iyadoo la adeegsanayo magaca ganacsiga "Fast as the wind".
