Tam sim no peb tham txog peb tiam nicotinic insecticide dinotefuran, cia peb xub txheeb xyuas qhov kev faib tawm ntawm cov tshuaj tua kab nicotinic.
Thawj tiam ntawm cov khoom nicotine: imidacloprid, nitenpyram, acetamiprid, thiacloprid.Lub ntsiab nruab nrab yog 2-chloro-5-chloromethylpyridine, uas belongs rau chloropyridyl pawg.
Cov khoom lag luam nicotine thib ob: thiamethoxam), clothianidin.Lub ntsiab nruab nrab yog 2-chloro-5-chloromethylthiazole, uas belongs rau chlorothiazolyl pawg.
Lub cim thib peb ntawm cov khoom nicotine: dinotefuran, pawg tetrahydrofuran hloov chloro pawg, thiab tsis muaj cov ntsiab lus halogen.
Lub tshuab ntawm nicotine insecticidal kev txiav txim yog ua rau cov hlab ntsha kis kab mob ntawm cov kab, ua rau lawv txawv txav zoo siab, tuag tes tuag taw thiab tuag, thiab tseem muaj kev cuam tshuam ntawm kev sib cuag tua thiab plab lom.Piv nrog cov tshuaj nicotines ib txwm muaj, dinotefuran tsis muaj cov ntsiab lus halogen, thiab nws cov dej solubility muaj zog dua, uas txhais tau hais tias dinotefuran tau yooj yim absorbed;thiab nws qhov ncauj toxicity rau muv tsuas yog 1/4.6 ntawm thiamethoxam, kev sib cuag toxicity yog ib nrab ntawm thiamethoxam.
Raws li lub Yim Hli 30, 2022, kuv lub tebchaws muaj 25 daim ntawv pov thawj rau cov khoom siv dinotefuran;164 daim ntawv pov thawj rau ib koob tshuaj thiab 111 daim ntawv pov thawj rau kev sib xyaw, suav nrog 51 tshuaj tua kab mob.
Cov ntaub ntawv sau npe muaj xws li soluble granules, suspending agents, water-dispersible granules, suspended seed coating agents, granules, etc., thiab cov ntsiab lus ib zaug yog 0.025% -70%.
Cov khoom sib xyaw muaj xws li pymetrozine, spirotetramat, pyridaben, bifenthrin, thiab lwm yam.
01 Dinotefuran + Pymetrozine
Pymetrozine muaj cov txiaj ntsig zoo ntawm kev ua haujlwm, thiab dinotefuran cov nyhuv nrawm yog qhov pom tseeb ntawm cov khoom no.Ob leeg muaj qhov sib txawv ntawm kev ua haujlwm.Thaum siv ua ke, cov kab tuag sai thiab cov nyhuv yuav kav ntev.02Dinotefuran + Spirotetramat
Cov mis no yog cov mis nemesis ntawm aphids, thrips, thiab whiteflies.Nyob rau hauv xyoo tas los no, los ntawm kev nce qib thiab siv ntau qhov chaw thiab cov neeg siv kev tawm tswv yim, cov nyhuv tseem yog qhov txaus siab heev.
03Dinotefuran + Pyriproxyfen
Pyriproxyfen yog ib qho kev ua haujlwm zoo ovicide, thaum dinotefuran tsuas yog siv tau rau cov neeg laus.Kev sib xyaw ua ke ntawm ob tuaj yeem tua tag nrho cov qe.Cov mis no yog tus khub golden kiag li.
04Dinotefuran + Pyrethroid Insecticides
Cov mis no tuaj yeem txhim kho cov nyhuv tshuaj tua kab.Cov tshuaj tua kab pyrethroid lawv tus kheej yog broad-spectrum insecticides.Kev sib xyaw ua ke ntawm ob tuaj yeem txo tus nqi ntawm cov tshuaj tiv thaiv, thiab tuaj yeem kho cov kab laum.Nws yog ib tug qauv dav txhawb los ntawm manufacturers nyob rau hauv xyoo tas los no.
daws kev daws teeb meem
Lub ntsiab nruab nrab ntawm dinotefuran yog tetrahydrofuran-3-methylamine thiab O-methyl-N-nitroisourea.
Kev tsim cov tetrahydrofuran-3-methylamine feem ntau yog nyob rau hauv Zhejiang, Hubei thiab Jiangsu, thiab lub peev xwm ntau lawm yog txaus kom tau raws li kev siv dinotefuran.
Kev tsim cov O-methyl-N-nitroisourea feem ntau yog nyob hauv Hebei, Hubei thiab Jiangsu.Nws yog qhov tseem ceeb tshaj plaws nruab nrab ntawm dinotefuran vim cov txheej txheem txaus ntshai cuam tshuam nrog nitrification.
01Dinotefuran muaj qhov dav dav ntawm cov tshuaj tua kab thiab kev siv ntau yam, los ntawm cov tshuaj tua kab rau cov tshuaj tu cev, los ntawm cov kab me mus rau kab loj, thiab muaj kev tswj xyuas zoo.
02Kev sib xyaw ua ke zoo, dinotefuran tuaj yeem sib xyaw nrog ntau yam tshuaj tua kab thiab fungicides, uas yooj yim siv;cov formulations yog nplua nuj, thiab nws yuav ua tau rau hauv granule fertilizer, noob txheej tus neeg saib xyuas rau cov noob hnav khaub ncaws, thiab tshem tawm tus neeg sawv cev rau tshuaj tsuag.
03Rice yog siv los tswj borers thiab planthoppers nrog ib tug tshuaj thiab ob tua.Nws yog tus nqi-zoo thiab yuav yog lub sijhawm ua lag luam loj rau dinotefuran txoj kev loj hlob yav tom ntej.
04Qhov nrov ntawm kev tiv thaiv ya ya, dinotefuran yog yooj yim soluble hauv dej, ua rau nws tsim nyog rau kev siv loj ntawm kev tiv thaiv ya.Qhov nrov ntawm kev tiv thaiv ya yuav muab lub sijhawm ua lag luam tsawg rau kev txhim kho yav tom ntej ntawm dinotefuran.
05Lub D-enantiomer ntawm dinotefuran tsuas yog muab cov tshuaj tua kab mob, thaum L-enantiomer yog tshuaj lom heev rau Italian honeybees.Nws ntseeg tau tias nrog kev ua kom huv ntawm cov thev naus laus zis thev naus laus zis, dinotefuran, uas yog tus phooj ywg zoo ib puag ncig, yuav tawg los ntawm nws tus kheej txoj kev loj hlob tsis muaj zog.
06Tsom ntsoov rau cov qoob loo niche, raws li leek maggots thiab qej maggots ua ntau resistant rau ntau cov tshuaj, dinotefuran tau ua tau zoo nyob rau hauv kev tswj ntawm maggot pests, thiab daim ntawv thov ntawm dinotefuran nyob rau hauv niche qoob loo kuj yuav muab kev lag luam tshiab thiab cov lus qhia rau kev loj hlob ntawm dinotefuran.
07Kev txhim kho tus nqi zoo.Qhov teeb meem loj tshaj plaws uas cuam tshuam rau kev loj hlob ntawm dinotefuran ib txwm yog tus nqi siab ntawm cov tshuaj thawj zaug thiab cov nqi thov siab ntawm qhov kev npaj davhlau ya nyob twg.Txawm li cas los xij, tus nqi ntawm dinotefuran tam sim no nyob rau theem qis hauv keeb kwm.Nrog rau qhov poob ntawm tus nqi, tus nqi-kev ua tau zoo piv ntawm dinotefuran tau dhau los ua qhov tseem ceeb.Peb ntseeg hais tias qhov kev txhim kho ntawm tus nqi-kev ua tau zoo piv muab ntau txoj hauv kev rau kev loj hlob yav tom ntej ntawm dinotefuran.
