Tsopano popeza tikukamba za m'badwo wachitatu wa nicotinic insecticide dinotefuran, tiyeni tiyambe tikambirane za gulu la nicotinic insecticide.
M'badwo woyamba wa mankhwala chikonga: imidacloprid, nitenpyram, acetamiprid, thiacloprid.Wapakati wamkulu ndi 2-chloro-5-chloromethylpyridine, womwe ndi wa gulu la chloropyridyl.
Zam'badwo wachiwiri wa chikonga: thiamethoxam), clothianidin.Wapakati wamkulu ndi 2-chloro-5-chloromethylthiazole, yemwe ndi wa gulu la chlorothiazolyl.
M'badwo wachitatu wa mankhwala chikonga: dinotefuran, tetrahydrofuran gulu m'malo chloro gulu, ndipo alibe zinthu halogen.
Limagwirira wa chikonga insecticidal kanthu ndi kuchita pa mitsempha kufala dongosolo tizilombo, kuwapangitsa iwo abnormally okondwa, ziwalo ndi kufa, komanso ali ndi zotsatira za kukhudzana kupha ndi m'mimba poizoni.Poyerekeza ndi chikonga chachikhalidwe, dinotefuran ilibe zinthu za halogen, ndipo kusungunuka kwake m'madzi kumakhala kolimba, zomwe zikutanthauza kuti dinotefuran imatengedwa mosavuta;ndipo kawopsedwe ka mkamwa kwa njuchi ndi 1/4.6 yokha ya thiamethoxam, kukhudzana ndi kawopsedwe ndi theka la thiamethoxam.
Pofika pa Ogasiti 30, 2022, dziko langa lili ndi ziphaso 25 zolembetsa zinthu zaukadaulo za dinotefuran;Ziphaso zolembetsa 164 za Mlingo umodzi ndi ziphaso 111 zolembetsa zosakaniza, kuphatikiza 51 mankhwala ophera tizilombo.
Mafomu a mlingo wolembetsedwa akuphatikiza ma granules osungunuka, zoyimitsa, zotayira m'madzi, zomata zambewu zoyimitsidwa, ma granules, ndi zina zotero, ndipo mlingo umodzi ndi 0.025% -70%.
Zosakaniza zimaphatikizapo pymetrozine, spirotetramat, pyridaben, bifenthrin, etc.
01 Dinotefuran + Pymetrozine
Pymetrozine ili ndi machitidwe abwino kwambiri a machitidwe, ndipo zotsatira zofulumira za dinotefuran ndizopindulitsa zoonekeratu za mankhwalawa.Awiriwa ali ndi machitidwe osiyanasiyana.Tikagwiritsidwa ntchito pamodzi, tizilombo timafa mwamsanga ndipo zotsatira zake zimakhala kwa nthawi yaitali.02Dinotefuran + Spirotetramat
Njira iyi ndi njira ya nemesis ya nsabwe za m'masamba, thrips, ndi whiteflies.M'zaka zaposachedwa, kuchokera pakulimbikitsa ndi kugwiritsa ntchito malo osiyanasiyana ndi ndemanga za ogwiritsa ntchito, zotsatira zake zimakhala zokhutiritsa kwambiri.
03Dinotefuran + Pyriproxyfen
Pyriproxyfen ndi ovicide yapamwamba kwambiri, pamene dinotefuran ndi yothandiza kwa akuluakulu okha.Kuphatikiza awiriwa kungathe kupha mazira onse.Fomula iyi ndi mnzake wagolide.
04Dinotefuran + Pyrethroid Insecticides
Izi chilinganizo akhoza kwambiri kusintha insecticidal zotsatira.Mankhwala ophera tizilombo a pyrethroid nawonso ndi opha tizilombo tosiyanasiyana.Kuphatikizika kwa ziwirizi kungachepetse kuchuluka kwa kukana mankhwala, komanso kuchiza kachilomboka.Ndi njira yomwe imalimbikitsidwa kwambiri ndi opanga zaka zaposachedwa.
Konzani chisankho
Zapakati pa dinotefuran ndi tetrahydrofuran-3-methylamine ndi O-methyl-N-nitroisourea.
Kupanga kwa tetrahydrofuran-3-methylamine makamaka ku Zhejiang, Hubei ndi Jiangsu, ndipo mphamvu yopanga ndi yokwanira kukwaniritsa ntchito ya dinotefuran.
Kupanga kwa O-methyl-N-nitroisourea makamaka ku Hebei, Hubei ndi Jiangsu.Ndiwofunikira kwambiri pakati pa dinotefuran chifukwa cha njira yowopsa yomwe imakhudzidwa ndi nitrification.
01Dinotefuran ili ndi mitundu yambiri ya tizilombo toyambitsa matenda ndi ntchito zosiyanasiyana, kuchokera ku mankhwala ophera tizilombo kupita ku mankhwala aukhondo, kuchokera ku tizilombo tating'ono kupita ku tizilombo toyambitsa matenda, ndipo imakhala ndi mphamvu yolamulira bwino.
02Kusakanikirana kwabwino, dinotefuran imatha kusakanikirana ndi mitundu yosiyanasiyana ya mankhwala ophera tizilombo ndi fungicides, omwe ndi osavuta kugwiritsa ntchito;Mapangidwe ake ndi olemera, ndipo amatha kupangidwa kukhala feteleza wa granule, chophikira mbewu pothirira mbewu, ndi kuyimitsidwa kupopera mbewu mankhwalawa.
03Mpunga umagwiritsidwa ntchito polimbana ndi borers ndi planthoppers ndi mankhwala amodzi ndi kupha kuwiri.Ndiwotsika mtengo ndipo ukhala mwayi waukulu wamsika wa kukula kwamtsogolo kwa dinotefuran.
04Kutchuka kwa kupewa kuwuluka, dinotefuran imasungunuka mosavuta m'madzi, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito kwambiri kupewa kuwuluka.Kutchuka kwa kupewa kuuluka kudzapereka mwayi wosowa wamsika wa chitukuko chamtsogolo cha dinotefuran.
05D-enantiomer wa dinotefuran makamaka amapereka ntchito zowononga tizilombo, pamene L-enantiomer ndi poizoni kwambiri ku njuchi za ku Italy.Akukhulupirira kuti ndi kupambana kwa ukadaulo woyeretsa, dinotefuran, yomwe ndi yochezeka kwambiri ndi chilengedwe, idzadutsa m'miyendo yake yachitukuko.
06Poyang'ana kwambiri mbewu zamtundu, monga mphutsi za leek ndi mphutsi za adyo zimagonjetsedwa kwambiri ndi mankhwala wamba, dinotefuran yachita bwino polimbana ndi tizirombo ta mphutsi, ndipo kugwiritsa ntchito dinotefuran mu mbewu za niche kudzaperekanso misika yatsopano ndi njira zopangira dinotefuran .
07Kuwongolera kotsika mtengo.Chopinga chachikulu chomwe chimakhudza kukula kwa dinotefuran nthawi zonse chakhala kukwera mtengo kwamankhwala oyambilira komanso kukwera mtengo kogwiritsa ntchito pokonzekera ma terminal.Komabe, mtengo wa dinotefuran pakali pano uli wochepa kwambiri m’mbiri.Ndi kutsika kwa mtengo, chiŵerengero cha mtengo-ntchito ya dinotefuran chakhala chowonekera kwambiri.Tikukhulupirira kuti kusintha kwa kuchuluka kwa magwiridwe antchito kumapereka mwayi wowonjezereka wa kukula kwamtsogolo kwa dinotefuran.
