Lufenuron exerts nws insecticidal nyhuv los ntawm inhibiting lub tsim ntawm larval chitin synthase thiab cuam tshuam nrog chitin deposition nyob rau hauv lub epidermis, uas tiv thaiv kab los ntawm ua kom tiav ib txwm molting thiab metamorphosis thiab nws thiaj li ua rau lawv tuag. Raws li cov khoom lag luam ntawm cov tshuaj tua kab benzoylurea, lufenuron tau tuav lub lag luam muaj zog nrog kev muag khoom tsis tu ncua txij li thaum nws tso tawm, ua tsaug rau nws cov txiaj ntsig zoo suav nrog kev ua haujlwm ovicidal muaj zog, ntev - kev tswj xyuas kab tsuag kav ntev thiab tsis muaj tus ntoo khaub lig- ua haujlwm.
Nrog rau ob qho tib si plab thiab kev sib cuag toxicity, lufenuron zoo tiv thaiv lepidopteran larvae, tho - nqus cov kab tsuag, thrips, xeb mites thiab lwm yam kab tsuag. Nws yog dav siv rau ntau yam qoob loo xws li txiv hmab txiv ntoo, zaub, paj rwb, pob kws thiab qos yaj ywm. Tsis tas li ntawd, nws ua rau muaj kev cuam tshuam me me rau cov neeg laus muaj txiaj ntsig kab thiab kab laug sab predatory, ua raws li lub tswv yim ntawm kev tiv thaiv kab tsuag ntsuab.
Txawm li cas los xij, lufenuron nta kuj qeeb sai - ua haujlwm zoo, nrog rau cov tshuaj tua kab mob siab tshaj plaws tshwm sim 3-5 hnub tom qab thov. Nws raug nquahu kom sib tov lossis sib xyaw nrog cov tshuaj tua kab nrawm.
1. Lufenuron + Abamectin
Cov tshuaj tua kab sib xyaw ntawm lufenuron thiab abamectin sib xyaw ua ke molting inhibition mechanism ntawm lufenuron thiab lub plab muaj zog lom tshuaj lom ntawm abamectin, ua tiav kev tswj hwm ntawm cov qe kab, cov menyuam yaus thiab cov laus larvae. Txij li thaum abamectin nquag mus rau photolysis, kev siv tshuaj tua kab yog qhia thaum sawv ntxov lossis yav tsaus ntuj. Cov teebmeem tseem ceeb tuaj yeem ua tiav ntawm qhov sib xyaw ntawm 1: 2 lossis hauv qhov hnyav feem pua ntawm 0.1 ~ 30 : 0.2 ~ 15.
2. Lufenuron + Emamectin Benzoate
Emamectin benzoate xa sai - ua haujlwm tau zoo, thaum lufenuron khav theeb ovicidal kev ua tau zoo thiab ntev - cov nyhuv kav ntev. Lawv qhov sib tov tuaj yeem siv tau thaum lub sij hawm peak qe hatching theem mus rau cov tub ntxhais hluas larval theem, nthuav tawm kev tswj tau zoo ntawm beet armyworm, nplej kab txaij qia borer thiab nplej daj qia borer, thiab kuj ua haujlwm zoo tiv thaiv kab laug sab mites. Daim ntawv thov kev pom zoo yog 800-fold dilution ntawm 5% lufenuron ncua kev kawm mloog zoo nrog 1000-fold dilution ntawm 3% emamectin benzoate.
3. Lufenuron + Chlorfenapyr
Chlorfenapyr yog ib qho tshuaj tua kab phenylpyrazole. Kev sib xyaw ua ke ntawm cov tshuaj tua kab nrog cov txheej txheem sib txawv kiag li ua tiav kev tswj hwm zoo tiv thaiv kab mob pob kws, ob-pom tub rog thiab lub caij nplooj zeeg tub rog. Qhov pom zoo kom noj rau pob kws yub theem yog 300-450 grams ib hectare. Tsis tas li ntawd, kev sib xyaw ntawm abamectin thiab chlorfenapyr kuj tseem muaj txiaj ntsig zoo rau kev tswj hwm ntawm cov nplooj nplooj nplooj.
