Chlorfenapyr: Nws yog ib hom tshiab ntawm pyrrole compound. Nws ua rau mitochondria ntawm cov hlwb hauv cov kab thiab ua haujlwm los ntawm kev ua haujlwm ntau yam oxidases hauv kab, feem ntau inhibiting kev hloov pauv ntawm cov enzymes.
Indoxacarb:Nws yog ib qho tshuaj tua kab oxadiazine zoo heev. Nws blocks sodium ion channels hauv kab paj hlwb, ua rau cov paj hlwb poob haujlwm. Qhov no ua rau cov kab tsuag ploj mus, ua tsis tau noj, ua rau tuag tes tuag taw thiab tuag thaum kawg.
Lufenuron: Cov tiam tshiab los hloov urea insecticides. Nws yog benzoyl urea insecticide uas tua cov kab tsuag los ntawm kev ua ntawm kab larvae thiab tiv thaiv cov txheej txheem tev.
Emamectin Benzoate: Emamectin Benzoate yog ib hom tshiab ntawm cov tshuaj tua kab mob semi-synthetic muaj txiaj ntsig zoo los ntawm cov khoom fermentation avermectin B1. Nws tau siv nyob rau hauv Suav teb tau ntev thiab tseem yog ib qho khoom siv tshuaj tua kab tam sim no.
1. Kev sib piv ntawm txoj kev siv tshuaj tua kab
Chlorfenapyr:Nws muaj lub plab lom thiab tiv tauj tua cov teebmeem. Nws muaj zog permeability ntawm nplooj nplooj thiab muaj qee yam kev cuam tshuam. Nws tsis tua qe.
Indoxacarb:Nws muaj lub plab lom thiab tiv tauj tua cov teebmeem, tsis muaj teebmeem hauv lub cev, thiab tsis muaj ovicide.
Lufenuron:Nws muaj lub plab lom thiab tiv thaiv kev tua, tsis muaj lub cev nqus, thiab muaj zog qe tua cov nyhuv.
Emamectin Benzoate:Nws yog feem ntau gastric lom thiab kuj muaj kev sib cuag tua nyhuv. Nws cov txheej txheem insecticidal yog los thaiv cov hlab ntsha ntawm cov kab tsuag.
Tag nrho tsib feem ntau yog mob plab thiab tiv tauj-tua. Cov nyhuv tua yuav ua tau zoo dua los ntawm kev ntxiv cov tshuaj tua kab / nthuav dav (cov tshuaj tua kab) thaum siv tshuaj tua kab.
2. Kev sib piv ntawm cov tshuaj tua kab
Chlorfenapyr: muaj kev tswj zoo heev tiv thaiv kev tho txawv, nqus thiab zom cov kab tsuag thiab kab tsuag, tshwj xeeb tshaj yog cov kab tsuag tiv taus Diamondback npauj, Spodoptera exigua, Spodoptera litura, nplooj ntoos, American pom leafminer, thiab pod borer. , thrips, kab laug sab liab mites, thiab lwm yam. Cov nyhuv zoo kawg nkaus;
Indoxacarb: Feem ntau yog siv los tswj cov kab mob lepidopteran xws li beet Armyworm, pob zeb diamondback npauj, kab ntsig kab ntsig, Spodoptera litura, paj rwb bollworm, haus luam yeeb kab ntsig, nplooj cov menyuam thiab lwm yam kab tsuag lepidopteran.
Lufenuron: Feem ntau yog siv los tswj cov kab tsuag xws li nplooj nplooj, npauj npaim pob zeb, kab ntsig kab ntsig, exigua exigua, Spodoptera litura, whiteflies, thrips, xeb zuam thiab lwm yam kab tsuag. Nws yog tshwj xeeb tshaj yog zoo nyob rau hauv kev tswj cov nplej nplooj yob.
Emamectin Benzoate: Nws muaj zog heev tiv thaiv kab mob lepidopteran kab thiab ntau lwm yam kab thiab kab. Nws muaj ob qho tib si plab lom thiab tiv tauj tua cov teebmeem. Rau Lepidoptera armyworm, qos tuber npauj, beet armyworm, codling npauj, peach heartworm, nplej borer, tripartite borer, cabbage caterpillar, European pob kws borer, melon nplooj cov menyuam, melon txhob lo lo ntxhuav borer, melon borer Ob borers thiab haus luam yeeb kab ntsig muaj kev tswj zoo. Tshwj xeeb tshaj yog zoo rau Lepidoptera thiab Diptera.
Broad spectrum insecticide: Emamectin Benzoate > Chlorfenapyr > Lufenuron > Indoxacarb
3. Kev sib piv ntawm cov kab tuag nrawm
Chlorfenapyr: 1 teev tom qab txau, cov kab tsuag tsis muaj zog, cov pob zeb tshwm sim, cov xim hloov, kev ua haujlwm nres, coma, tuag tes tuag taw, thiab thaum kawg tuag, mus txog qhov kawg ntawm cov kab tsuag tuag hauv 24 teev.
Indoxacarb: Indoxacarb: Kab tso tseg tsis pub dhau 0-4 teev thiab tuag tes tuag taw tam sim ntawd. Cov kab muaj peev xwm sib koom ua ke yuav txo qis (uas yuav ua rau cov larvae poob los ntawm cov qoob loo), thiab lawv feem ntau tuag hauv 1-3 hnub tom qab kho.
Lufenuron: Tom qab cov kab tsuag tuaj rau hauv kev sib cuag nrog cov tshuaj tua kab thiab pub rau ntawm nplooj uas muaj cov tshuaj tua kab, lawv lub qhov ncauj yuav tsum tau tshuaj loog tsis pub dhau 2 teev thiab tsis pub noj, yog li txwv tsis pub cov qoob loo. Lub ncov ntawm cov kab tuag yuav ncav cuag hauv 3-5 hnub.
Emamectin Benzoate: Cov kab tsuag ua rau tuag tes tuag taw, nres noj, thiab tuag tom qab 2-4 hnub. Kev tua ceev yog qeeb.
Tus nqi tshuaj tua kab: Indoxacarb ＞ Lufenuron ＞ Emamectin Benzoate
4. Kev sib piv ntawm lub sijhawm siv tau
Chlorfenapyr: Tsis tua qe, tab sis muaj kev tswj xyuas zoo rau cov kab laus. Lub sijhawm tswj hwm yog li 7-10 hnub.
Indoxacarb: Tsis tua qe, tab sis tua cov kab mob lepidopteran loj thiab me. Cov nyhuv tswj yog li 12-15 hnub.
Lufenuron: Nws muaj lub zog tua qe thiab lub sijhawm tswj kab yog ntev, txog li 25 hnub.
Emamectin Benzoate: Cov nyhuv ntev ntawm cov kab tsuag, 10-15 hnub, thiab mites, 15-25 hnub.
Lub sijhawm siv tau: Emamectin Benzoate ＞ Lufenuron ＞ Indoxacarb ＞ Chlorfenapyr
