Mankhwala abwino kwambiri a herbicide m'minda ya paddy--Tripyrasulfone

Tripyrasulfone, kapangidwe kake kakuwonetsedwa mu Chithunzi 1, China Patent Authorization Announcement No. m'minda kuletsa udzu gramineous.

 

Njira yochitira:

Triazole sulfotrione ndi mtundu watsopano wa herbicide womwe umalepheretsa p-hydroxyphenylpyruvate dioxygenase (HPPD), yomwe imasintha p-hydroxyphenylpyruvate kukhala mkodzo poletsa ntchito ya HPPD muzomera. Njira ya asidi wakuda imatsekedwa, zomwe zimapangitsa kuti plastoquinone ipangidwe, ndipo plastoquinone ndi cofactor yaikulu ya phytoene desaturase (PDS), ndipo kuchepetsa plastoquinone kumalepheretsa mphamvu ya PDS, yomwe imakhudzanso biosynthesis ya carotenoids. m'thupi lomwe mukufuna, zomwe zimapangitsa kuti masamba akhale alubino komanso kufa.

 

Makhalidwe amachitidwe:

1. Tripyrasulfone ndi choletsa chatsopano cha HPPD, komwe ndi koyamba kuti HPPD inhibitor igwiritsidwe ntchito mosamala pochiritsa tsinde ndi masamba m'munda wa mpunga.

2. Tripyrasulfone imatha kuthetsa vuto la njere zosamva bwino komanso udzu wosamva zambiri wa barnyardgrass ndi barnyardgrass.

3. Palibe kusagwirizana pakati pa Tripyrasulfone ndi mankhwala omwe alipo, omwe angathe kuthetsa mavuto amakono ndi amtsogolo ovuta kwambiri olimbana ndi mapira ndi udzu wa barnyard.

4. Tripyrasulfone atha kusakanizidwa ndi 2 methyl · methazopine kuti azitha kulamulira bwino udzu ndi udzu wanthambi komanso kuti pakhale bwino.

 

Mfundo zofunika kuziganizira:

1. Pamaso ntchito, m`pofunika kuchita chatsekedwa mankhwala kuchepetsa udzu m`munsi ndi masamba m`badwo.

2. Tripyrasulfone sangasakanizidwe ndi organophosphorus, carbamate, paclobutrazol insecticides ndi fungicides kapena kugwiritsidwa ntchito mkati mwa masiku 7. Ikhoza kugwiritsidwa ntchito kamodzi pa nthawi yonse ya kukula kwa mpunga.

3. Ndi zoletsedwa kufalitsa fetereza masiku 7 isanayambe kapena itatha.

Ndi zoletsedwa kusakaniza ntchito bensulfuron-methyl, pentaflusulfurochlor ndi zina ALS zoletsa ndi quinclorac.

4. Nyengo ndi yotentha, ndipo kutentha kwabwino kwambiri kupopera mbewu mankhwalawa ndi 25 ~ 35 ℃. Ngati kutentha kupitirira 38 ℃, kupopera mbewu mankhwalawa sikuvomerezeka. Ngati mvula yagwa pasanathe maola 8 mutapopera mbewu mankhwalawa, kupopera mbewu mankhwalawa mowonjezera kumafunika.

5. Kukhetsa madzi musanapopera mbewu mankhwalawa kuonetsetsa kuti masamba opitilira 2/3 a udzu ali pamadzi ndikuthira mankhwala ophera tizilombo; Pambuyo pakugwiritsa ntchito mankhwala ophera tizilombo, madziwo amabwerera ku 5-7 cm mkati mwa maola 24-48 ndikusungidwa kwa masiku opitilira 7. Kutalikirapo kwa nthawi yosungira madzi, mphamvu yolamulira imakhala yokhazikika.

6. Mitundu ina ya mpunga ya indica imakhudzidwa kwambiri ndi Tripyrasulfone, zomwe zingayambitse khungu la alubino, koma likhoza kubwezeretsedwa, popanda kusokoneza zokolola za mpunga.

 

Chidule:

Tripyrasulfone ili ndi mitundu yambiri ya mankhwala ophera udzu komanso ntchito yopalira pambuyo pa mmera, makamaka Echinochloa crus-galli, Leptochloa chinensis, Monochoria vaginalis ndi Eclipta prostrata, ndipo ilibe kutsutsana ndi mankhwala ophera udzu omwe amapezeka m'minda ya mpunga, monga cyhalochlor, pentafluorosulphonachlor ndi dichloroquinoline acid. Panthawi imodzimodziyo, ndi yabwino kwa mbande za mpunga ndipo ndi yoyenera kuyikapo mpunga ndi minda yobzala mbewu mwachindunji, ndi wothandizira kuthetsa vuto la udzu wa mankhwala m'munda wa paddy pakali pano - kulamulira udzu wosagwirizana ndi barnyard ndi mapira. chiyembekezo chachikulu chogwiritsa ntchito. Kupyolera mu mayesero ambiri, anapeza kuti mankhwala ambiri ofotokozedwa mu Tripyrasulfone ali ndi kusankha bwino kwa udzu wa udzu monga Zoysia japonica, bermudagrass, tall fescue, bluegrass, ryegrass, seashore paspalum, ndipo amatha kulamulira udzu wambiri wa udzu ndi udzu wambiri. . Mayeso a soya, thonje, mpendadzuwa, mbatata, mtengo wa zipatso ndi ndiwo zamasamba pansi pa njira zosiyanasiyana zogwiritsira ntchito adawonetsanso kusankhidwa bwino komanso phindu la malonda.
