Fludioxonilyog ib qho uas tsis yog -cov kab mob phenylpyrrole fungicide uas muaj txiaj ntsig zoo tiv thaiv cov noob- thiab av- kab mob kis los ntawm ntau tus kab mob, suav nrog Ascomycetes, Basidiomycetes, thiab Deuteromycetes. Nws cov txheej txheem tshwj xeeb ntawm kev ua kom tshem tawm cov ntoo khaub lig- tawm tsam nrog lwm cov tshuaj fungicides paub.
Thaum lub sij hawm germination, fludioxonil yog absorbed nyob rau hauv me me, tswj cov kab mob zoo nyob rau hauv cov noob thiab caryopsis. Fludioxonil tseem nyob twj ywm hauv av, muab kev tiv thaiv ntev ntev rau cov cag qoob loo. Tsis tas li ntawd, nws cov txheej txheem zoo tshaj plaws tso cai rau cov noob txheej sai yam tsis muaj qhov tawg.
Ua tsaug rau cov txiaj ntsig zoo no, cov ntaub ntawv sau npe qhia tau hais tias fludioxonil tau mus txog 153 kev sau npe rau kev kho cov noob, ua rau nws yog ib qho tseem ceeb hauv kev ua lag luam rau av -kev tswj kab mob.
Mechanism ntawm Action
Fludioxonil feem ntau inhibits qabzib phosphorylation- cuam tshuam txog kev hloov pauv hauv cov fungus thiab inhibits fungal mycelial loj hlob, ua rau cov kab mob tuag.
Khoom nta
1. Fludioxonil yog ib qho pyrrole tshiab -raws li, tsis yog -systemic, dav -spectrum fungicide. Raws li cov noob kev kho mob fungicide, cov txheej txheem tshem tawm cov noob tuaj yeem tswj tau ntau yam kab mob. Cov ntawv thov tau pom tias fludioxonil, txawm tias siv los ua cov hauv paus irrigation lossis kev kho av, muaj txiaj ntsig zoo tiv thaiv kab mob hauv paus xws li damping -tawm, hauv paus rot, wilt, thiab vine blight rau ntau yam qoob loo.

2. Cov khoom xyaw nquag muaj kev tswj xyuas zoo tiv thaiv ntau yam kab mob ntawm Ascomycetes, Basidiomycetes, thiab Deuteromycetes. Thaum siv los ua kev kho cov noob, tsuas yog ib qho me me ntawm cov khoom muaj txiaj ntsig yog absorbed thaum lub sij hawm kho thiab germination, tab sis nws zoo tua cov kab mob ntawm cov noob saum npoo thiab hauv lub tsho tiv no. Tsis muaj tus ntoo khaub lig- tawm tsam nrog cov tshuaj fungicide tam sim no.
3. Fludioxonil tsim cov yeeb yaj kiab sai, tsis yog- los thaum siv los kho cov noob. Cov khoom xyaw nquag tseem nyob hauv av, ua kom ruaj khov thiab ntev ntev - kev tiv thaiv kev tiv thaiv ib puag ncig ntawm cov noob. Nrog rau ntev - cov nyhuv kav ntev tshaj li plaub lub hlis, nws tuaj yeem siv los ntawm cov neeg ua liaj ua teb rau kev hnav khaub ncaws yooj yim los yog los ntawm kev lag luam noob rau loj - nplai mechanized noob hnav khaub ncaws.
4. Nws muaj kev nyab xeeb heev rau cov noob qoob loo, tsis cuam tshuam rau cov noob tshwm sim, thiab tuaj yeem txhawb nqa cov noob thaum ntxov, zoo ib yam, thiab muaj zog ntawm cov noob. Nws tseem muaj kev nyab xeeb heev rau tib neeg thiab tsiaj txhu, nrog rau cov tshuaj toxicity qis dua li cov ntsev ntsev.
