IProtoporphyrinogen oxidase (PPO) yenye yezinto ekujoliswe kuzo ekuphuhlisweni kweentlobo ezintsha zemichiza yokutshabalalisa ukhula, ebalelwa kumlinganiselo omkhulu wemarike.Ngenxa yokuba lo mchiza ukhula usebenza kwiklorofili kwaye unetyhefu ephantsi kwizilwanyana ezanyisayo, lo mchiza ukhula uneempawu zokusebenza kakuhle, ubutyhefu obuphantsi kunye nokhuseleko.
Izilwanyana, izityalo, iibhaktheriya kunye nefungi zonke ziqulethe iprotoporphyrinogen oxidase, eyenza iprotoporphyrinogen IX kwiprotoporphyrin IX phantsi kwemeko ye-molecular oxygen, iprotoporphyrinogen oxidase yi-enzyme yokugqibela eqhelekileyo kwi-tetrapyrrole biosynthesis, ngokukodwa i-synthesizing chlorophyll heme kunye ne-chlorophyll heme.Kwizityalo, iprotoporphyrinogen oxidase ine-isoenzymes ezimbini, ezifumaneka kwi-mitochondria kunye ne-chloroplasts ngokulandelanayo.I-Protoporphyrinogen oxidase inhibitors zi-herbicides zoqhagamshelwano ezinamandla, ezinokufikelela injongo yokutshatyalaliswa kokhula ikakhulu ngokuthintela ukuhlanganiswa kwemibala yezityalo, kwaye ibe nexesha elifutshane lokuhlala emhlabeni, elingenabungozi kwizityalo ezizayo.Iindidi ezintsha zolu khula zineempawu zokukhetha, umsebenzi ophezulu, ubuthi obuphantsi kwaye akulula ukuqokelela kwindawo engqongileyo.
I-PPO inhibitors yeentlobo eziphambili ze-herbicide
1. Imichiza yokutshabalalisa ukhula iDiphenyl ether
Ezinye iintlobo zePPO zamva nje
3.1Igama le-ISO elithi saflufenacil elifunyenwe kwi-2007 - BASF, i-patent iphelelwe yisikhathi kwi-2021.
Kwi-2009, i-benzochlor yabhaliswa okokuqala e-United States kwaye yathengiswa ngo-2010. I-Benzochlor okwangoku ibhaliswe e-United States, eCanada, e-China, eNicaragua, eChile, e-Argentina, eBrazil nase-Australia.Okwangoku, amashishini amaninzi eTshayina akwinkqubo yokubhalisa.
3.2 Uphumelele igama le-ISO elithi tiafenacil ngo-2013 kwaye ipatent iphela ngo-2029.
Kwi-2018, i-flursulfuryl ester yaqala ukuqaliswa eMzantsi Korea;Ngo-2019, yasungulwa eSri Lanka, ivula uhambo lokukhuthaza imveliso kwiimarike zaphesheya.Okwangoku, i-flursulfuryl ester iye yabhaliswa e-Australia, e-United States, eCanada, eBrazil nakwamanye amazwe, kwaye ibhaliswe ngokusebenzayo kwezinye iimarike ezinkulu.
3.3 Igama le-ISO elithi trifludimoxazin (trifluoxazin) lifunyenwe ngo-2014 kwaye i-patent iphela ngo-2030.
NgoMeyi 28, 2020, iyeza lokuqala le-trifluoxazine labhaliswa e-Australia okokuqala ngqa emhlabeni, kwaye inkqubo yorhwebo yehlabathi jikelele ye-trifluoxazine yaqhubela phambili ngokukhawuleza, kwaye nge-1 kaJulayi waloo nyaka, imveliso ye-BASF (125.0g / L tricfluoxazine + 250.0g / L ukumiswa kwe-benzosulfuramide) nayo yamkelwa ukuba ibhaliswe e-Australia.
I-3.4 Igama le-ISO le-cyclopyranil elifunyenwe kwi-2017 - i-patent iphela ngo-2034.
Inkampani yaseJapan ifake isicelo selungelo elilodwa lomenzi wechiza laseYurophu (EP3031806) kwikhompawundi jikelele, kubandakanywa ikhompawundi ye-cyclopyranil, kwaye ingenise isicelo se-PCT, ushicilelo lwamazwe ngamazwe No. I-Itali, iJapan, iSouth Korea, iRussia kunye neUnited States.
I-3.5 epyrifenacil inikwe igama le-ISO ngo-2020
I-Epyrifenacil i-spectrum ebanzi, isiphumo esikhawulezayo, esisetyenziswa kakhulu kwingqolowa, ingqolowa, irhasi, irayisi, amazimba, imbotyi yesoya, umqhaphu, i-beet yeswekile, i-peanut, i-sunflower, udlwengulo, iintyatyambo, izityalo zokuhombisa, imifuno, ukukhusela ukhula oluninzi olunamagqabi kunye nokhula lwengca. , ezifana ne-setae, ingca yenkomo, ingca yasebayeni, i-ryegrass, i-tail grass njalo njalo.
3.6 ISO ebizwa ngokuba yiflufenoximacil (Flufenoximacil) ngo-2022
I-Fluridine sisichiza se-PPO inhibitor esinokhula olubanzi, isantya sokusebenza ngokukhawuleza, sisebenza kwangaloo mini yokufakwa kwayo, kunye nokuguquguquka okuhle kwizityalo ezilandelayo.Ukongezelela, i-fluridine nayo inomsebenzi we-ultra-high, ukunciphisa inani lezithako ezisebenzayo ze-insecticidal herbicides ukuya kwinqanaba legram, elihambelana nokusingqongileyo.
Ngo-Epreli ka-2022, i-fluridine yabhaliswa eCambodia, uluhlu lwayo lokuqala kwihlabathi.Imveliso yokuqala equlethe le nxalenye ephambili iya kufakwa e-China phantsi kwegama lezorhwebo "Fast as the wind".
