I-Tripyrasulfone, ifomyula yesakhiwo iboniswe kuMfanekiso 1, i-China yeSibhengezo soGunyaziso lwePatent No. : CN105399674B, CAS: 1911613-97-2) yeyokuqala yehlabathi i-HPPD inhibitor herbicide esetyenziswa ngokukhuselekileyo kwi-post-emergence yesiqu kunye neqabunga lonyango. amasimi ukuze kutshatyalaliswe ukhula lwegrama.
Indlela yokwenza:
I-Triazole sulfotrione luhlobo olutsha lwe-herbicide oluvimbela i-p-hydroxyphenylpyruvate dioxygenase (HPPD), eguqula i-p-hydroxyphenylpyruvate ibe ngumchamo ngokuvimbela umsebenzi we-HPPD kwizityalo. Inkqubo ye-asidi emnyama ivaliwe, nto leyo ekhokelela kwi-synthesis engaqhelekanga ye-plastoquinone, kunye ne-plastoquinone yi-cofactor ephambili ye-phytoene desaturase (PDS), kunye nokunciphisa i-plastoquinone kuthintela isenzo se-catalytic se-PDS, nto leyo echaphazela i-biosynthesis ye-carotenoids. kumzimba ekujoliswe kuwo, okukhokelela kwi-albinism yamagqabi kunye nokufa.
Iimpawu zomsebenzi:
1. I-Tripyrasulfone yi-HPPD inhibitor entsha, okokuqala ngqa ukuba i-HPPD inhibitor isetyenziswe ngokukhuselekileyo kwi-post seedling stem kunye ne-leaf spray treatment kwintsimi yerayisi.
2. I-Tripyrasulfone inokusombulula ngempumelelo ingxaki yembewu exhathisayo kunye ne-multi-resistant barnyardgrass kunye ne-barnyardgrass.
3. Akukho ukuxhathisa ukusebenzisana phakathi kwe-Tripyrasulfone kunye neyeza eliqhelekileyo langoku, elinokusombulula ngokufanelekileyo iingxaki zangoku kunye nezexesha elizayo ezintsonkothileyo zokuxhathisa i-millet kunye ne-barnyard grass.
4. I-Tripyrasulfone inokuxutywa nesixa esifanelekileyo se-2 methyl · methazopine ukuze kuphuculwe ulawulo lwengca ye-broadleaf grass kunye ne-sedge ukhula kunye nokuphucula ukusebenza kakuhle kokukhula.
Imiba efuna ukuqwalaselwa:
1. Ngaphambi kokusetyenziswa, kuyimfuneko ukuqhuba unyango oluvaliweyo ukunciphisa isiseko sokhula kunye nobudala beqabunga.
2. I-Tripyrasulfone ayinakuxutywa nayiphi na i-organophosphorus, i-carbamate, i-paclobutrazol inambuzane kunye ne-fungicides okanye isetyenziswe kwiintsuku ze-7. Ingasetyenziswa kanye ngexesha lonke lokukhula kwerayisi.
3. Akuvunyelwe ukusasaza isichumisi kwiintsuku ezisi-7 ngaphambi nangemva kwesicelo.
Akuvunyelwe ukuxuba ukusetyenziswa kwe-bensulfuron-methyl, pentaflusulfurochlor kunye nezinye i-ALS inhibitors kunye ne-quinclorac.
4. Imozulu inelanga, kwaye elona qondo lobushushu lokutshiza liyi-25~35 ℃. Ukuba ubushushu bungaphezulu kwe-38 ℃, ukutshiza akukhuthazwa. Ukuba kukho imvula kwiiyure ezisi-8 emva kokutshiza, isitshizi esongezelelweyo siyafuneka.
5. Khupha amanzi phambi kokutshiza ukuze uqinisekise ukuba ngaphezu kwe-2/3 yamagqabi okhula atyhileke emanzini kwaye ugalele ngokupheleleyo isibulali-zinambuzane; Emva kokusetyenziswa kwe-pesticide, amanzi abuyiselwa kwi-5 ~ 7 cm kwiiyure ezingama-24-48 kwaye agcinwe ngaphezu kweentsuku ze-7. Xa ixesha lokugcinwa kwamanzi lide, isiphumo solawulo sizinzile.
6. Ezinye iindidi zerayisi ze-indica zinovakalelo kwi-Tripyrasulfone, enokukhokelela kwi-albinism yamagqabi, kodwa inokufunyanwa kwakhona, ngaphandle kokuchaphazela isivuno serayisi.
Isishwankathelo:
I-Tripyrasulfone inoluhlu olubanzi lwemichiza yokutshabalalisa ukhula kunye nomsebenzi ophezulu wokuhlakula emva kokuhlwayelwa kwezithole, ngakumbi i-Echinochloa crus-galli, iLeptochloa chinensis, iMonochoria vaginalis kunye ne-Eclipta prostrata, kwaye ayinakumelana nokumelana nemichiza yokutshabalalisa ukhula ekhoyo ngoku kumasimi erayisi, njengecyhalochlor, pentafluorosulphonachlor kunye ne-dichloroquinoline acid. Kwangaxeshanye, ikhuselekile kwizithole zerayisi kwaye ilungele ukutyalwa kwerayisi kunye namasimi okuhlwayela ngokuthe ngqo, Yiarhente esebenzayo yokusombulula ingxaki yokhula lwekhemikhali kwintsimi ye-paddy ngoku - ukulawula ingca ye-barnyard kunye ne-millet exhathisayo, kwaye amathemba osetyenziso olubanzi. Ngeemvavanyo ezininzi, kwafunyaniswa ukuba ezininzi iikhompawundi ezichazwe kwi-Tripyrasulfone zinokukhetha okulungileyo kwingca yengca efana ne-Zoysia japonica, i-bermudagrass, i-fescue ende, i-bluegrass, i-ryegrass, i-seashore paspalum, kwaye inokulawula ukhula oluninzi lwengca kunye nokhula olunamagqabi abanzi. . Iimvavanyo zeembotyi zesoya, umqhaphu, ujongilanga, iitapile, umthi weziqhamo kunye nemifuno phantsi kweendlela ezahlukeneyo zokufaka izicelo nazo zibonise ukukhetha okugqwesileyo kunye nexabiso lentengiso.
