Difenoconazole triazole broad-spectrum fungicide rau kev tiv thaiv qoob loo
Khoom piav qhia
Difenoconazole yog ib hom tshuaj tua kab mob triazole.Nws yog ib tug fungicide nrog ntau yam kev ua, tiv thaiv tawm los thiab zoo los ntawm foliar daim ntawv thov los yog noob kev kho mob.Nws yuav siv tau los ntawm kev ua raws li inhibitor ntawm sterol 14α-demethylase, thaiv cov biosynthesis ntawm sterol.Los ntawm inhibiting cov txheej txheem sterol biosynthesis, nws inhibits mycelia kev loj hlob thiab germination ntawm pathogens los ntawm spores, thaum kawg suppressing proliferation ntawm fungi.Difenoconazole tau siv dav hauv ntau cov qoob loo hauv ntau lub teb chaws vim nws muaj peev xwm tswj tau ntau yam kab mob fungal.Nws kuj yog ib qho tseem ceeb tshaj plaws thiab dav siv tshuaj tua kab rau kev tswj kab mob hauv cov nplej.Nws muab kev ua haujlwm ntev thiab kho kom zoo tiv thaiv Ascomycetes, Basidiomycetes thiab Deuteromycetes.Nws yog siv los tiv thaiv kab mob complexes hauv txiv hmab txiv ntoo, pome txiv hmab txiv ntoo, pob zeb txiv hmab txiv ntoo, qos yaj ywm, qab zib beet, oilseed rape, txiv tsawb, ornamentals thiab ntau yam zaub qoob loo.Nws kuj tseem siv tau los ua cov noob kho tawm tsam ntau yam kab mob hauv cov nplej thiab barley.Hauv cov nplej, cov ntawv thov foliar thaum ntxov ntawm kev loj hlob theem 29-42 yuav ua rau, qee qhov xwm txheej, chlorotic spotting ntawm nplooj, tab sis qhov no tsis cuam tshuam rau kev tawm los.
Muaj txwv luam tawm cov ntaub ntawv ntawm cov metabolism ntawm difenoconazole.Nws maj mam dissipated nyob rau hauv cov av, thiab cov metabolism hauv cov nroj tsuag muaj rupture ntawm triazole linkage los yog oxidation ntawm phenyl nplhaib ua raws li conjugation.
Environmental Fate:
Tsiaj txhu: tom qab kev tswj hwm qhov ncauj, difenoconazole tau tshem tawm sai sai rau tag nrho, nrog rau cov zis thiab quav.Cov seem hauv cov ntaub so ntswg tsis tseem ceeb thiab tsis muaj pov thawj rau kev sib sau.Txawm hais tias muaj peev xwm ntawm lub xov tooj ntawm tes nws yuav tsis zoo li leach vim nws cov dej tsis tshua muaj dej.Txawm li cas los xij, nws muaj peev xwm ua rau particle bound thauj.Nws yog me ntsis volatile, tsis tu ncua nyob rau hauv cov av thiab nyob rau hauv cov dej ib puag ncig.Muaj qee qhov kev txhawj xeeb txog nws lub peev xwm rau bioaccumulation.Nws yog tshuaj lom rau tib neeg, tsiaj txhu, noog thiab feem ntau cov kab mob hauv dej.
