Lufenuron
Lufenuron yog ib hom kev ua haujlwm siab, dav spectrum thiab tsis tshua muaj tshuaj tua kab mob los tiv thaiv kab molting.Nws tsuas yog muaj kev mob plab, tab sis kuj muaj qee yam kev cuam tshuam.Nws tsis muaj kev txaus siab sab hauv, tab sis muaj txiaj ntsig zoo.Cov nyhuv ntawm Lufenuron rau cov menyuam yaus yog qhov zoo tshwj xeeb.Tom qab noj cov nroj tsuag txau nrog cov tshuaj tua kab, cov kab tsuag tsis pub noj rau 2 teev thiab nkag mus rau qhov kawg ntawm cov kab tuag hauv 2-3 hnub.
Nws muaj kev nyab xeeb rau ntau cov yeeb ncuab ntuj vim nws qhov ua tau zoo qeeb thiab ua haujlwm ntev.
Chlorfenapyr
Chlorfenapyr muaj qee yam cuam tshuam rau kev ua ovicidal.Ua ke nrog kev kwv yees thiab kev kwv yees ntawm cov kab tsuag, nws tau pom tias cov tshuaj tsuag tuaj yeem ua kom muaj kev tswj xyuas zoo ntawm qhov kawg ntawm cov kab tsuag los yog qe hatching.
Chlorfenapyr muaj qhov ua tau zoo hauv zos hauv cov nroj tsuag, thiab cov nyhuv tib yam tuaj yeem tau txais ntawm cov nplooj hauv qab ntawm cov kab tsuag.
Cov nyhuv tswj yog 90-100% hauv L-3 hnub tom qab siv tshuaj, thiab cov nyhuv tseem ruaj khov ntawm 90% hauv 15 hnub tom qab siv tshuaj.Cov koob tshuaj pom zoo yog 30-40 ml ib mu, nrog rau lub sijhawm ntawm 15-20 hnub.
Yuav tsum tau them nyiaj tshwj xeebThaum siv Chlorfenapyr:
1) Nws yog rhiab heev rau cov txiv lws suav, zucchini, iab gourd, melon, cantaloupe, gourd dawb, taub dag, cantaloupe, loofah thiab lwm yam qoob loo.Tsis pom zoo nyob rau hauv cov tub ntxhais hluas nplooj theem.
2) Tsis txhob siv tshuaj nyob rau hauv qhov kub thiab txias, flowering theem thiab seedling theem;
Qhov txawv ntawmChlorfenapyr thiabLufenuron
1. Kev siv tshuaj tua kab
Lufenuron muaj cov nyhuv ntawm lub plab lom thiab kov, tsis muaj lub siab sab hauv, muaj zog qe tua;
Chlorfenapyr muaj lub plab toxicity thiab tactility, thiab muaj qee yam kev nqus sab hauv.
Kev siv cov tshuaj osmotic/extender (xws li, silicone) yuav ua rau kom muaj txiaj ntsig zoo ntawm kev tua.
2. Insecticidal spectrum
Nws yog tsuas yog siv rau hauv kev tswj cov nplooj ntoos, Plutella xylostella, Rapeseed, beet armyworm, Spodoptera litura, whitefly, thrips, xeb zuam thiab lwm yam kab tsuag, tshwj xeeb tshaj yog nyob rau hauv kev tswj ntawm cov nplej nplooj ntoos roller.
Lufenuron muaj kev tswj xyuas zoo rau cov kab tsuag thiab kab tsuag, tshwj xeeb tshaj yog rau cov kab tsuag uas tiv taus xws li Plutella xylostella, Exigua beet armyworm, Exigua chinensis, nplooj ntoos, American chaw miner, pod borer, thrips thiab starred kab laug sab.
Yog li ntawd, qhov sib txawv dav raws li cov kab mob tua kab mob yog: Chlorfenapyr > Lufenuron > Indoxacarb
3, Kev tua ceev
Kev sib cuag nrog cov tshuaj tua kab thiab pub rau ntawm nplooj nrog cov tshuaj tua kab, lub qhov ncauj yuav tsum tau tshuaj loog tsis pub dhau 2 teev, tsis pub noj, kom tsis txhob ua phem rau cov qoob loo, 3-5 hnub kom ncav cuag qhov kawg ntawm cov kab tuag;
Ib teev tom qab kev kho tshuaj tua kab fenfenitrile, kev ua haujlwm ntawm cov kab tsuag tsis muaj zog, qhov chaw tshwm sim, xim hloov, kev ua haujlwm nres, coma, limp, thiab thaum kawg ua rau tuag, thiab qhov kawg ntawm cov kab tuag tau mus txog hauv 24 teev.
Yog li ntawd, raws li cov tshuaj tua kab ceev, qhov sib piv yog: Chlorfenapyr > Lufenuron
4. Lub sijhawm khaws cia
Lufenuron muaj cov nyhuv ovicidal muaj zog, thiab lub sijhawm tiv thaiv kab tsuag yog qhov ntev, txog li 25 hnub;
Chlorfenapyr tsis tua cov qe, tab sis nws tsuas yog siv tau rau cov kab laus, thiab lub sijhawm tswj yog li 7-10 hnub.
Chlorfenapyr > Lufenuron
5. Nplooj tuav tus nqi
Lub hom phiaj kawg ntawm kev tua kab yog tiv thaiv kab tsuag los ntawm kev ua phem rau cov qoob loo.Raws li kev ceev thiab qeeb qeeb ntawm cov kab tsuag los yog ntau dua thiab tsawg dua, qib ntawm cov nplooj tiv thaiv tus nqi yog qhov ntsuas kawg los ntsuas tus nqi ntawm cov khoom.
Piv nrog rau kev tswj cov nyhuv ntawm cov hmoov nplej, cov nplooj khaws cia ntawm louciacaride thiab fenfenitrile mus txog ntau dua 90% thiab txog 65%, feem.
Yog li ntawd, raws li nplooj tuav tus nqi, qhov sib piv yog: Chlorfenapyr > Lufenuron
6. Kev nyab xeeb
Txog tam sim no, tsis muaj cov tshuaj tiv thaiv kab mob.Nyob rau tib lub sijhawm, cov tshuaj tua kab yuav tsis ua rau muaj kev cuam tshuam ntawm stabbing thiab nqus cov kab tsuag, thiab muaj cov nyhuv me me rau cov neeg laus ntawm cov kab zoo thiab kab laug sab predation.
Chlorfenapyr yog rhiab heev rau cruciferous zaub thiab melons, thiab tuaj yeem ua rau muaj kev puas tsuaj rau cov tshuaj thaum siv rau qhov kub thiab txias.
Yog li, kev sib piv ntawm kev nyab xeeb yog: Lufenuron > Chlorfenapyr
