Tripyrasulfone, chimiro chechimiro chinoratidzwa muMufananidzo 1, China Patent Authorization Chiziviso Nhamba : CN105399674B, CAS: 1911613-97-2) ndiyo yekutanga HPPD inhibitor herbicide pasi rose iyo inoshandiswa zvakachengetedzeka mukurapwa kweshizha nemashizha. minda yekudzora sora regramineous.
Mechanism yekuita:
Triazole sulfotrione rudzi rutsva rwemishonga inodzivirira p-hydroxyphenylpyruvate dioxygenase (HPPD), iyo inoshandura p-hydroxyphenylpyruvate kuita weti nekudzivisa basa reHPPD mumiti. Iyo nzira yeblack acid yakavharwa, iyo inotungamira kune isina kujairika synthesis yeplastoquinone, uye plastoquinone ndiyo yakakosha cofactor ye phytoene desaturase (PDS), uye kuderedzwa kweplastoquinone kunotadzisa catalytic chiito chePDS, iyo inokanganisa iyo biosynthesis yecarotenoids. mumuviri wakanangwa, zvichitungamira kune mashizha albinism uye kufa.
Maitiro ekuita:
1. Tripyrasulfone inhibitor itsva yeHPPD, inova kekutanga kuti HPPD inhibitor ichishandiswa zvisina njodzi padzinde rembeu nepfapfaidzo yemashizha mumunda wemupunga.
2. Tripyrasulfone inokwanisa kugadzirisa zvinobudirira dambudziko rembeu dzinoramba uye dzakawanda-resistant barnyardgrass uye barnyardgrass.
3. Hapana kupindirana kwekupikisa pakati peTripyrasulfone nemushonga wemazuva ano wemazuva ano, unogona kugadzirisa zvinobudirira matambudziko azvino uye eramangwana ekupikisa mapira nehuswa hwebarnyard.
4. Tripyrasulfone inogona kusanganiswa nehuwandu hwakakodzera hwe2 methyl · methazopine kuti ivandudze kutonga kwehuswa hwakafara nehuswa hwesadza nekuvandudza kusakura.
Nyaya dzinoda kutariswa:
1. Usati washandisa, zvakakosha kuitisa kurapwa kwakavharwa kuderedza uswa hwemasora uye zera remashizha.
2. Tripyrasulfone haigoni kusanganiswa nechero organophosphorus, carbamate, paclobutrazol insecticides uye fungicides kana kushandiswa mukati memazuva manomwe. Inogona kushandiswa kamwechete panguva yese yekukura kwemupunga.
3. Inorambidzwa kuparadzira fetereza mazuva manomwe isati yasvika uye mushure mekushandisa.
Zvinorambidzwa kusanganisa kushandiswa kwebensulfuron-methyl, pentaflusulfurochlor uye mamwe ALS inhibitors uye quinclorac.
4. Mamiriro ekunze ane zuva, uye tembiricha yekupfapfaidza yakanaka i25~35 ℃. Kana tembiricha yakadarika 38 ℃, kupfapfaidza hakukurudzirwe. Kana mvura ikanaya mukati memaawa masere mushure mekupfapfaidza, kupfapfaidza kwekuwedzera kunodiwa.
5. Dhonza mvura usati wamwaya kuti uone kuti zvinopfuura 2/3 zvemashizha esora zvinoiswa mumvura uye kunyatsoshandisa mushonga wezvipembenene; Mushure mekushandiswa kwepesticide, mvura inodzoserwa ku5 ~ 7 cm mukati meawa 24 ~ 48 uye inochengetwa kwemazuva anopfuura manomwe. Iyo yakareba nguva yekuchengetedza mvura, iyo yakanyanya kugadzikana kudzora maitiro.
6. Dzimwe mhando dzemupunga we indica dzinonzwa neTripyrasulfone, izvo zvinogona kutungamira kuAlbinism yemashizha, asi inogona kuwanikwa zvakare, pasina kukanganisa goho remupunga.
Pfupiso:
Tripyrasulfone ine huwandu hwakawanda hwemishonga yesora uye yakakwira mushure mekudyara kusakura, kunyanya yeEchinochloa crus-galli, Leptochloa chinensis, Monochoria vaginalis neEclipta prostrata, uye haina kupesana nemishonga yesora iripo muminda yemupunga, senge cyhalochlor, pentafluorosulphonachlor uye dichloroquinoline acid. Panguva imwecheteyo, haina njodzi kumbesa yemupunga uye inokodzera kuisirwa mupunga uye kuminda yakananga mbeu, Mushonga unoshanda wekugadzirisa dambudziko rekusakura kwemakemikari mumunda wepaddy pari zvino - kudzora huswa hwebhari nemapfunde, uye ane tarisiro huru yekushandisa. Kuburikidza nemiedzo yakawanda, zvakaonekwa kuti mazhinji emakomisheni anotsanangurwa muTripyrasulfone ane sarudzo yakanaka yehuswa huswa hwakadai seZoysia japonica, bermudagrass, tall fescue, bluegrass, ryegrass, seashore paspalum, uye inogona kudzora akawanda akakosha uswa sora uye yakakura-mashizha masora. . Iwo bvunzo dzesoya bean, donje, sunflower, mbatatisi, muti wemichero uye muriwo pasi penzira dzakasiyana dzekushandisa dzakaratidzawo kusarudzwa kwakanaka uye kukosha kwekutengesa.
