Nyob rau hauv xyoo tas los no, ntawm cov tshuaj tua kab uas siv los tswj aphids, thrips thiab lwm yam kab tsuag ntawm qhov ncauj, spirotetramat feem ntau hais. Yog li hnub no peb yuav tham txog spirotetramat thiab yuav siv nws li cas kom ua tiav cov txiaj ntsig zoo tshaj plaws?
1. Khoom nta
Spirattramat belongs rau chav kawm tshiab ntawm quaternary acid derivative insecticides. Nws tsuas yog siv cov tshuaj lom hauv plab, ntxiv los ntawm kev sib cuag tshuaj lom, thiab tuaj yeem siv los tswj cov aphids, thrips, whiteflies, nplai kab, kab stink thiab lwm yam tho qhov ncauj thiab lwm yam kab tsuag.
Nws tuaj yeem siv los tswj cov txiv lws suav, dib, kua txob, txiv lws suav, qos yaj ywm, taum pauv, paj rwb, txiv hmab txiv ntoo, citrus thiab lwm yam qoob loo. Nws muaj txiaj ntsig zoo rau cov neeg laus, larvae, nymphs thiab qe. Nws muaj cov yam ntxwv ntawm kev siv tshuaj tua kab dav dav, tua ob lub qe thiab kab, lub sijhawm ntev ntawm cov nyhuv, ob txoj hauv kev nqus dej thiab muaj zog xaiv.
2. Mechanism ntawm kev ua
Lub mechanism ntawm kev txiav txim ntawm spirotetramat yog inhibit lub synthesis ntawm cov rog los ntawm inhibiting lub biosynthesis txheej txheem ntawm cov rog nyob rau hauv lub cev ntawm cov kab tsuag, thaiv lub cev lub zog metabolism ntawm kab tsuag, thiab thaum kawg ua rau cov kab tsuag tuag. Cov txheej txheem tshwj xeeb yog tias thaum cov kua tshuaj txau rau ntawm qhov chaw ntawm cov qoob loo stems thiab nplooj, tom qab absorbed los ntawm stems thiab nplooj, cov tshuaj yuav muab bidirectionally kis mus rau tag nrho cov cheeb tsam ntawm cov nroj tsuag los ntawm phloem thiab xylem. qoob loo.
Yog li ntawd, txawm hais tias cov kab tsuag tau muab zais rau hauv cov nplooj curled, paj, los yog txiv hmab txiv ntoo bark, tsuav yog cov kab tsuag noj thiab nqus cov kua txiv ntawm cov qoob loo, lawv yuav ua rau lom. Nws tuaj yeem tua cov qoob loo thiab cov kab tsuag zais, thiab tseem tiv thaiv cov nplooj tshiab, paj thiab txiv hmab txiv ntoo tom qab txau.
Raws li cov txheej txheem saum toj no ntawm kev nqis tes ua, spirotetramat yog qhov khoom siv tshuaj tua kab zoo nkauj, thiab nws yuav tsis muaj qhov tsis txaus ntseeg los tswj. Txawm li cas los xij, hauv kev siv tiag tiag, muaj ntau qhov xwm txheej uas kab tua maj mam thiab cov tshuaj tua kab tsis raug tua tag. Yuav ua li cas?
3. Ua rau kev tsom xam
(1) Cov kab tuag qeeb. Spirattramat feem ntau yog mob plab thiab ntxiv los ntawm kev sib cuag lom. Qhov ntawd yog hais tias, tsuas yog thaum cov kab tsuag nqus cov kua txiv hmab txiv ntoo uas muaj tus neeg sawv cev tuaj yeem spirotetramat zoo. Los ntawm kev txau cov tshuaj tua kab, kom xa cov kua hauv cov nroj tsuag, thiab tom qab ntawd mus rau cov kab tsuag uas nqus nws, cov txheej txheem no yuav siv sij hawm ntau tshaj li "txhaj cov kua ncaj qha mus rau saum npoo ntawm cov kab tsuag kom muaj txiaj ntsig (hu rau tua)".
Yog tias cov tshuaj tua kab tsis txau sib npaug txaus thiab nyob deb ntawm qhov chaw pub mis ntawm cov kab tsuag, nws yuav siv sij hawm ntev dua rau cov tshuaj tua kab kom kis tau mus rau qhov chaw no.
(2) Cov tshuaj tua kab tsis zoo. Spiratretate yog ib qho lipid biosynthesis inhibitor thiab yog li ntawd tshwj xeeb tshaj yog zoo rau larvae uas loj hlob sai. Rau cov neeg laus cov kab uas nws lub cev nyob ze rau "tsim" thiab nws cov lipid biosynthetic kev ua haujlwm yog qhov tsis muaj zog, kev tswj cov nyhuv yog me ntsis tsis txaus. Qhov no kuj yog qhov laj thawj tseem ceeb vim li cas ntau tus neeg ua liaj ua teb qhia tias tshuaj tua kab tsis tiav.
Nyob rau tib lub sijhawm, kev tua qe ntawm spirotetramat kuj qee qhov txwv. Yog vim li cas kuj yog ib qho yooj yim, vim hais tias cov qe twv yuav raug hu tsis nquag txhawb thiab pub, yog li lawv tuaj yeem ua haujlwm tsuas yog thaum lawv txau nrog cov kua. Txau cov qe feem ntau tsis tuaj yeem hle ib txwm, yog li tua cov qe.
Hmoov zoo, lub sijhawm ntawm cov nyhuv ntawm spirotetramat yog qhov ntev. Txawm hais tias qee lub qe uas tsis tau txau, lawv tseem yuav raug tshem tawm sai li sai tau thaum lawv pib pub mis. Tab sis yuav muaj ib txwm muaj "qe" uas plam hauv lub vas, thiab nws tsis tuaj yeem ua kom tiav thiab tua lawv tag nrho.
Tsis tas li ntawd, nrog kev siv tsis tu ncua nyob rau hauv xyoo tas los no, cov teeb meem kev tiv thaiv ntawm qhov sib txawv tau tshwm sim nyob rau hauv ntau qhov chaw, thiab kev tswj cov nyhuv kuj tau txo qis heev.
4. Yuav ua li cas txhim kho kev tiv thaiv thiab tswj cov teebmeem
(1) Lub sijhawm siv tshuaj yog qhov tseem ceeb, siv "sab sawv ntxov" es tsis yog " lig". Thaum pom cov kab tsuag hauv thaj teb, cov tshuaj tua kab yuav tsum tau siv tam sim ua ntej cov kab tsuag nyob rau theem larval thiab ua ntej lawv loj hlob. Tsuas yog nyob rau hauv txoj kev no nws tuaj yeem ua tau "tawm" cov kab tsuag kom huv si. Thaum cov kab tsuag mus txog rau theem neeg laus, kev tswj xyuas yuav tsis zoo li qub.
(2) Txawm hais tias cov tshuaj kho tau sai thiab nqus tau los ntawm cov qoob loo tag nrho yog qhov tseem ceeb ntawm seb spirotetramat puas tuaj yeem tswj cov kab tsuag zoo. Yog li ntawd, thaum siv, cov tshuaj tsuag yuav tsum zoo ib yam li qhov ua tau. Rau qee cov qoob loo nrog cov waxy txheej rau ntawm qhov chaw uas tsis yooj yim rau nqus cov kua, nws yog qhov zoo tshaj rau ntxiv silicone los yog cov kws tshaj lij additives los txhawb kev sib kis thiab nkag mus rau cov kua kom nws tau sai sai absorbed los ntawm cov qoob loo.
(3) Tiv thaiv thiab tswj cov kab tsuag kom zoo dua los ntawm kev sib xyaw lossis sib xyaw ntawm cov tshuaj tua kab. Kev sib xyaw thiab sib xyaw nrog cov tshuaj tua kab tuaj yeem txhim kho cov nyhuv sai ntawm cov tshuaj tua kab. Kev sib xyaw thiab kev sib xyaw nrog cov tshuaj tua kab nrog cov txheej txheem sib txawv ntawm kev ua haujlwm tuaj yeem ua rau qeeb ntawm kev tsim cov tshuaj tua kab hauv cov kab tsuag. Feem ntau suav nrog kev sib xyaw thiab sib xyaw ntawm spirotetramat nrog abamectin, pymetrozine, chlorpyrifos, imidacloprid, dinotefuran, thiacloprid, buprofen, thiab lwm yam.
Nyob rau tib lub sijhawm, spirotetramat tuaj yeem sib xyaw nrog fungicides, regulators, foliar chiv, thiab lwm yam rau tib lub sijhawm tiv thaiv thiab tswj cov kab tsuag thiab kab mob, txhim kho qoob loo, thiab nce yields.
