Khoom piav qhia
Boscalid muaj ib tug dav spectrum ntawm bactericidal kev ua si thiab muaj ib tug tiv thaiv nyhuv, ua active tiv thaiv yuav luag txhua hom kab mob fungal.Nws muaj cov txiaj ntsig zoo ntawm kev tswj cov kab mob mildew, grey pwm, kab mob hauv paus rot, sclerotinia thiab ntau yam kab mob rot thiab tsis yooj yim los tsim cov kab mob sib kis.Nws kuj tseem siv tau rau cov kab mob resistant rau lwm tus neeg.Nws yog tsuas yog siv rau kev tiv thaiv thiab tswj cov kab mob cuam tshuam nrog rape, grapes, txiv hmab txiv ntoo ntoo, zaub thiab teb cov qoob loo.Cov txiaj ntsig tau pom tias Boscalid muaj txiaj ntsig zoo rau kev kho mob ntawm Sclerotinia sclerotiorum nrog rau ob qho tib si kev tswj hwm tus kab mob thiab cov kab mob tswj kev ntsuas tau siab dua 80%, uas zoo dua li lwm tus neeg sawv cev tam sim no nrov.
Boscalid yog ib hom mitochondrion respiration inhibitor, yog tus inhibitor ntawm succinate dehydrogenase (SDHI) uas ua los ntawm inhibiting succinate coenzyme Q reductase (tseem hu ua complex II) ntawm mitochondrial electron thauj saw, nrog nws cov txheej txheem ntawm kev ua haujlwm zoo ib yam li ntawd. ntawm lwm yam amide thiab benzamide fungicides.Nws muaj kev cuam tshuam rau tag nrho lub sij hawm loj hlob ntawm cov kab mob, tshwj xeeb tshaj yog muaj zog inhibitory nyhuv tawm tsam cov kab mob germination.Nws kuj muaj cov txiaj ntsig zoo prophylactic thiab zoo heev intra-nplooj permeability.
Boscalid yog foliar daim ntawv thov germicide, uas tuaj yeem nkag mus vertically thiab kis mus rau saum cov nplooj nplooj.Nws muaj kev tiv thaiv zoo heev thiab muaj qee yam kev kho mob.Nws tuaj yeem cuam tshuam cov kab mob spores, kab mob elongation thiab txuas tsim, thiab ua haujlwm tau zoo nyob rau hauv tag nrho lwm yam kev loj hlob ntawm cov kab mob, nthuav tawm zoo heev tiv thaiv los nag yaig thiab persistence.
Boscalid muaj ib tug tsawg aqueous solubility thiab tsis volatile.Nws tuaj yeem ua tau ntev heev nyob rau hauv ob qho tib si av thiab dej systems nyob ntawm seb lub zos tej yam kev mob.Muaj qee qhov kev pheej hmoo ntawm leaching rau hauv av.Nws muaj mob me me rau feem ntau fauna thiab floras txawm tias muaj kev pheej hmoo tsawg rau zib mu muv.Boscalid muaj qhov ncauj qhov ncauj tsis tshua muaj tshuaj lom.
