Dab tsi yogTembotrione?
Tembotrione(Kev loj hlob code AE 0172747) yog cov tshuaj tua kab mob herbicide tsim los ntawm Bayer AG rau siv hauv pob kws. Nws yog phau ntawv tshiab sib xyaw ua ke los ntawm kev ntxiv ib pawg trifluorothoxy rau cov qauv ntawm Sulcotrione. Raws li ib qho inhibitor ntawm 4 {{4 4}} hydrockyfas (hpps} Nws tau khav ntau dua nws cov neeg ua ntej dua li nws cov neeg ua ntej, sulcotrione thiab mesotrione, muab ib qho kev tswj hwm dav dav, tsis muaj kev tiv thaiv cov dej ntws, thiab muaj zog tiv thaiv kom los nag-tawm. Nrog nws cov tseem ceeb patents nyob rau xyoo 2019, qhov kev xav tau tus tshuaj Herbicide no tau ua rau muaj kev cuam tshuam tseem ceeb hauv kev lag luam xws li Tuam Tshoj.
Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig zoo
Tembotrione cov khoom siv txheej txheem yog cov hmoov beige nrog cov hnoos qeev qis rau cov tsiaj ua haujlwm thiab ib puag ncig zoo nkauj toxicology profile. Nws cov qauv tshuaj, muaj ntau yam tshuaj fluorine atoms, txhim kho nws lipophilicity, membrane permeability, thiab kev ruaj khov, ua rau cov kev ua si zoo dua.
Nws cov ntsiab lus tseem ceeb muaj xws li:
Broad -} spectrum maj mam tswj:Nws siv tau zoo ntawm ntau txoj kev nyom txhua xyoo thiab cov lus uas tau tsim los tiv thaiv glyphosate, dicamba, thiab cov als inibitors.
High efficacy thiab siv tus nqi qis:Nws yog nquag muaj nyob ntawm cov nqi thov tsawg (feem ntau 6-8 grams ib evre).
Ntev Thov Qhov rai:Nws muaj ib qho kev thov hloov tau yooj yim, los ntawm post -}}}} theem ntawm pob kws, muaj txiaj ntsig zoo dua mesotrione uas yuav tsum tau thov ntxov.
Kev caij ntuj nag zoo tshaj:Nws cov qauv tsim muaj zog tiv thaiv kom los nag - tawm sai tom qab daim ntawv thov.
Kev Nyab Xeeb Qoob:Thaum siv nrog tus Safeerer Isoxadifen, nws yog qhov kev xaiv rau pob kws. Nws tseem muaj cov ntaub ntawv kev nyab xeeb zoo rau cov qoob loo txuas ntxiv, muab cov nroj tsuag tsim nyog-} rov qab cov sij hawm yog pom.
Mechanism ntawm Kev Ua: Inhibiting HPPD
Tembotrione ua haujlwm los ntawm kev cuam tshuam HPPD enzyme. Cov enzyme no tseem ceeb heev nyob rau hauv biosynthesis ntawm plastoquinone thiab tocopherols hauv cov nroj tsuag. Plastoquinone yog qhov tseem ceeb co - qhov tseem ceeb hauv kev tsim khoom ntawm carotenoid. Los thaiv HPPD, Tembotrione cuam tshuam carotenoid saptenoid synthesis, ua kom dawb ntawm chlorophyll hauv cov noob zaub. Cuam tshuam cov nroj tsuag tig dawb thiab tuag tsis pub dhau 1 mus rau 2 asthiv.
Synthesis thiab cov qauv
Kev lag luam hluav taws xob ntawm Tembotrione feem ntau pib txij li 3 -} metylaniline. Kev Tshawb Fawb los ntawm cov koom haum Suav tau tsim muaj txiaj ntsig, kev siv tau nqi, thiab kev txhawb nqa kev ua haujlwm zoo hauv cov kev sib txuas lus zoo nrog high loo.
Tembotrione yog tsim rau ntau hom khoom, suav nrog suav nrog ncua kev kawm (SC) thiab roj dispersion (od). Nws yog feem ntau muag raws li cov khoom lag luam solo lossis hauv ntej pib kom txhim kho nws cov spectrum thiab tswj kev tswj hwm. TSEEM sib xyaw muaj xws li:
Nrog safeers:Isoxadifen (piv txwv li, hauv Laudis®) los tiv thaiv cov pob kws cog qoob loo.
Nrog lwm cov tshuaj tua kab:Thiencarbazone - methyl (piv txwv li, hauv capreno®), trazine, thiab bromoxynil kom dav txoj kev tswj hwm cov nroj tsuag spectrum.
Pov thawj teb kev ua tau zoo
Kev sim teb tau pom Tembotrione qhov ua tau zoo. Piv txwv li, kev sim siab nrog 5% Tembotrione od nyob rau hauv lub caij nplooj ntoo hlav tau pom zoo heev ntawm kev tswj hwm txhua xyoo ntawm tus nqi ntawm txhua xyoo / hi, uas tsis muaj phytotoxicity rau pob kws cog qoob loo.
Lwm qhov kev sim siv cov qauv txheej txheem tembotrione, Nicosulfuron, thiab kev tswj hwm ntawm cov nroj tsuag uas tsis zoo nyob rau 90%
Xaus: Lub neej yav tom ntej
Tembotrione tau khov kho tsim nws tus kheej ua ib tug thawj coj pos -} Tawm Tsam Rau Pob Kws. Nrog nws cov haujlwm siab, broad- kev siv spectrum, daim ntawv thov hloov tau lub sijhawm, thiab cov kev xaiv muaj zog thiab tus neeg sib tw mus rau mesotrione. Kev tas sij hawm ntawm nws cov ntxhais sib tw qhib lub qhov rooj rau kev tsim dav thiab tsim cov qauv, uas yuav tsum tau ua rau nws cov kev lag luam thiab kev sib tw. Muab nws lub peev xwm loj thiab ua pov thawj, Tembotrione tau teeb tsa los ua kev ua haujlwm tseem ceeb tshaj plaws hauv kev tswj hwm tam sim no rau xyoo tom ntej.
