Protoporphyrinogen oxidase (PPO) yog ib lub hom phiaj tseem ceeb rau kev txhim kho cov tshuaj tua kab mob tshiab, suav nrog feem ntau ntawm kev ua lag luam. Vim tias cov tshuaj tua kab mob no feem ntau ua rau chlorophyll thiab tsis muaj tshuaj lom rau cov tsiaj, cov tshuaj tua kab no muaj cov yam ntxwv ntawm kev ua haujlwm siab, tsis muaj tshuaj lom thiab kev nyab xeeb.
Tsiaj txhu, nroj tsuag, kab mob thiab cov fungi tag nrho muaj protoporphyrinogen oxidase, uas catalyzes protoporphyrinogen IX rau protoporphyrin IX nyob rau hauv cov mob ntawm molecular oxygen, protoporphyrinogen oxidase yog lub xeem enzyme nyob rau hauv tetrapyrrole biosynthesis, mas synthesizing ferrous heme thiab chlorophyll. Hauv cov nroj tsuag, protoporphyrinogen oxidase muaj ob isoenzymes, uas nyob hauv mitochondria thiab chloroplasts feem. Protoporphyrinogen oxidase inhibitors yog cov tshuaj tua kab mob muaj zog, uas tuaj yeem ua tiav lub hom phiaj ntawm kev tswj cov nroj tsuag feem ntau los ntawm inhibiting cov synthesis ntawm cov nroj tsuag pigments, thiab muaj lub sij hawm luv luv nyob rau hauv av, uas tsis muaj teeb meem rau cov qoob loo tom qab. Cov hom tshiab ntawm cov tshuaj tua kab no muaj cov yam ntxwv ntawm kev xaiv, kev ua haujlwm siab, tsis muaj tshuaj lom thiab tsis yooj yim rau hauv ib puag ncig.
PPO inhibitors ntawm lub ntsiab herbicide ntau yam
1. Diphenyl ether tshuaj tua kab mob
Qee hom PPO tsis ntev los no
3.1 Lub npe ISO saflufenacil tau txais xyoo 2007 - BASF, patent tau tas sijhawm hauv 2021.
Nyob rau hauv 2009, benzochlor yog thawj zaug sau npe nyob rau hauv lub tebchaws United States thiab tau ua lag luam nyob rau hauv 2010. Benzochlor yog tam sim no sau npe nyob rau hauv lub tebchaws United States, Canada, Tuam Tshoj, Nicaragua, Chile, Argentina, Brazil thiab Australia. Tam sim no, ntau lub lag luam hauv Suav teb tab tom sau npe.
3.2 Yeej lub npe ISO tiafenacil hauv 2013 thiab patent tas rau xyoo 2029.
Hauv 2018, flursulfuryl ester tau pib ua ntej hauv Kaus Lim Qab Teb; Nyob rau hauv 2019, nws tau launched nyob rau hauv Sri Lanka, qhib txoj kev mus rau kev txhawb cov khoom nyob rau hauv txawv teb chaws kev lag luam. Tam sim no, flursulfuryl ester kuj tau sau npe hauv Australia, Tebchaws Meskas, Canada, Brazil thiab lwm lub tebchaws, thiab tau koom nrog rau lwm lub lag luam loj.
3.3 Lub npe ISO trifludimoxazin (trifluoxazin) tau txais nyob rau hauv 2014 thiab patent tas rau xyoo 2030.
Thaum lub Tsib Hlis 28, 2020, thawj cov tshuaj ntawm trifluoxazine tau sau npe hauv Australia thawj zaug hauv ntiaj teb, thiab cov txheej txheem kev lag luam thoob ntiaj teb ntawm trifluoxazine tau nce sai, thiab thaum Lub Xya Hli 1 ntawm tib lub xyoo, BASF cov khoom sib xyaw (125.0g / L tricfluoxazine + 250.0g / L benzosulfuramide ncua kev kawm ntawv) kuj tau pom zoo rau npe hauv Australia.
3.4 ISO lub npe cyclopyranil tau txais hauv 2017 - patent tas sij hawm hauv 2034.
Ib lub tuam txhab Nyij Pooj tau thov rau European patent (EP3031806) rau cov khoom siv dav dav, suav nrog cyclopyranil compound, thiab xa daim ntawv thov PCT, kev tshaj tawm thoob ntiaj teb No. WO2015020156A1, hnub tim 7 Lub Yim Hli 2014. Cov patent tau tso cai hauv Suav teb, Australia, Brazil, Ltalis, Nyiv, Kaus Lim Qab Teb, Russia, thiab Tebchaws Meskas.
3.5 Epyrifenacil tau txais ISO lub npe hauv xyoo 2020
Epyrifenacil broad spectrum, ceev nyhuv, feem ntau yog siv rau hauv pob kws, nplej, barley, mov, sorghum, soybean, paj rwb, qab zib beet, txiv laum huab xeeb, sunflower, rape, paj, ornamental nroj tsuag, zaub, los tiv thaiv ntau broad-leaved weeds thiab nyom nyom. , xws li setae, nyuj nyom, barnyard nyom, ryegrass, tail nyom thiab lwm yam.
3.6 ISO lub npe hu ua flufenoximacil (Flufenoximacil) hauv xyoo 2022
Fluridine yog PPO inhibitor herbicide nrog cov nroj tsuag dav dav, kev ua haujlwm sai, ua haujlwm tau zoo nyob rau tib hnub ntawm daim ntawv thov, thiab hloov tau zoo rau cov qoob loo tom ntej. Tsis tas li ntawd, fluridine kuj muaj kev ua haujlwm siab heev, txo cov khoom xyaw nquag ntawm cov tshuaj tua kab tua kab rau qib gram, uas yog ib puag ncig zoo.
Thaum lub Plaub Hlis 2022, fluridine tau sau npe hauv Cambodia, nws thawj cov npe thoob ntiaj teb. Thawj cov khoom uas muaj cov khoom tseem ceeb no yuav raug teev nyob rau hauv Suav teb raws li lub npe lag luam "Fast as the wind".
