Qhov sib txawv ntawm Permethrin thiab Dinotefuran

I. Permethrin

1. Cov khoom siv yooj yim

Permethrin yog cov tshuaj tua kab hluavtaws, thiab nws cov qauv tshuaj muaj cov yam ntxwv ntawm cov tshuaj pyrethroid. Nws feem ntau yog xim tsis muaj xim rau lub teeb daj oily kua nrog cov ntxhiab tsw tshwj xeeb. Nws yog insoluble nyob rau hauv dej, yooj yim soluble nyob rau hauv cov organic solvents, ruaj khov rau lub teeb, tab sis nquag decomposition nyob rau hauv alkaline tej yam kev mob.

2. Kev siv tseem ceeb

Hauv kev ua liaj ua teb: Nws tuaj yeem siv los tswj ntau yam kab tsuag ua liaj ua teb, xws li cov paj rwb, zaub, txiv hmab txiv ntoo thiab lwm yam qoob loo.

Hais txog kev tswj cov kab tsuag kom huv: Nws muaj kev tswj xyuas zoo ntawm cov kab tsuag xws li yoov tshaj cum, yoov tshaj cum thiab nab, thiab tuaj yeem siv rau kev tiv thaiv kab tsuag hauv tsev neeg, cov chaw pej xeem, thiab lwm yam. Los ntawm txoj kev xws li tshuaj tsuag cov khoom seem, kev pheej hmoo ntawm cov kab tsuag thiab kab mob sib kis tau raug txo.

II.Dinotefuran

1. Cov khoom siv yooj yim

Dinotefuranbelongs rau peb-tiam neonicotinoid insecticides. Nws zoo nkaus li dawb crystalline hmoov.

2. Kev siv tseem ceeb

Hauv kev ua liaj ua teb, nws yog siv los tswj cov aphids, leafhoppers, planthoppers, thrips, whiteflies thiab lawv cov kab mob resistant rau ntau yam qoob loo xws li hom qoob mog, nplej, paj rwb, zaub, txiv hmab txiv ntoo ntoo thiab luam yeeb nplooj. Nyob rau tib lub sijhawm, nws muaj txiaj ntsig zoo rau Coleoptera, Diptera, Lepidoptera thiab homoptera kab tsuag. Nws kuj tseem siv tau los tswj cov kab tsuag hauv tsev xws li kab laum. Muab tso rau hauv cov ces kaum los yog crevices qhov twg kab laum nquag tshwm sim, xws li tom qab cov txee thiab cov khoom siv hluav taws xob, thiab ua kom zoo dua ntawm nws qhov muaj zog permeability kom ua tiav cov txiaj ntsig ntawm kev tshem tawm cov kab laum.

III. Qhov sib txawv ntawm Permethrin thiab Dinotefuran

1. Hais txog toxicity

Hais txog kev sib piv ntawm qib toxicity ntawm ob, cov kev tshawb fawb sib txawv thiab daim ntawv thov scenarios yuav ua rau cov txiaj ntsig sib txawv. Cov kev tshawb fawb tau pom tias furosemide muaj cov tshuaj toxicity tsawg thiab tuaj yeem siv tau ntev. Txawm li cas los xij, cyfluthrin (zoo ib yam li cyfluthrin) muaj tshuaj lom ntau dua thiab yuav tsum tsis txhob siv sijhawm ntev. Tab sis kev sib piv tshwj xeeb ntawm cov tshuaj lom ntawm cyfluthrin thiab furfuramide tseem xav tau kev tshawb fawb tshwj xeeb ntxiv los txiav txim.

2. Hais txog lub tshuab ua haujlwm

Permethrin feem ntau cuam tshuam nrog neural conduction system ntawm cov kab tsuag, tiv thaiv lawv los ntawm kev txav mus los thiab ua rau lawv tuag. Furfuran ua haujlwm los ntawm kev cuam tshuam nrog cov kab mob metabolic ntawm kab laum (noj kab laum ua piv txwv, nws cov txheej txheem ntawm kev tawm tsam lwm yam kab tsuag zoo ib yam), tiv thaiv lawv los ntawm kev loj hlob thiab rov ua dua qub. Nws kuj tseem muaj kev tswj xyuas zoo heev ntawm kev tho-nqus qhov ncauj qhov ncauj kab tsuag thiab qhia tau hais tias cov tshuaj tua kab mob siab heev ntawm koob tshuaj tsawg heev.

3. Hais txog cov khoom ntawm kev tiv thaiv thiab tswj

Permethrin feem ntau yog siv los tswj cov kab tsuag xws li yoov tshaj cum, yoov, yoov thiab ntshauv. Hauv kev ua liaj ua teb, nws tuaj yeem tswj tau ntau yam kab tsuag. Fumefon feem ntau yog siv los tswj aphids, leafhoppers, planthoppers thiab lwm yam tshuaj tua kab rau ntau yam qoob loo. Nws kuj muaj kev tswj xyuas zoo rau cov kab tsuag hauv tsev xws li kab laum. Tsis tas li ntawd, nws muaj peev xwm tswj tau zoo dua ntawm cov kab tsuag uas tau tsim los tiv thaiv nicotinoid cov neeg ua haujlwm.
