Pydiflumetofen yog ib qho pyrazole amide fungicide nrog cov qauv tshiab molecular, muaj cov kab mob bactericidal siab thiab dav spectrum. Nyob rau tib lub sijhawm, hom fungicide no muaj cov txheej txheem sib txawv ntawm kev ua haujlwm los ntawm classic benzimidazole, triazole thiab methoxyenoate tshuaj tua kab thiab tsis tshua muaj peev xwm tsim cov kab mob sib kis.
Mechanism ntawm kev ua
Lub mechanism ntawm kev txiav txim ntawm triflufenac yog hais tias nws yog ib tug succinate dehydrogenase inhibitor. Los ntawm kev ua ntawm succinate dehydrogenase (SDH), ib qho ntawm cov hubs txuas oxidative phosphorylation thiab electron thauj hauv cov kab mob, nws ua rau muaj kev cuam tshuam ntawm tricarboxylic acid voj voog (TAC). Nws cuam tshuam lub zog metabolism ntawm cov kab mob, yog li inhibiting germination ntawm cov kab mob fungal spores, kev loj hlob ntawm cov kab mob thiab mycelium, ua rau kev tuag ntawm cov kab mob, yog li ua tiav lub hom phiaj ntawm kev tiv thaiv kab mob thiab kev kho mob. Nws yog ib qho zoo heev fungicide tsim nyob rau hauv xyoo tas los.
Triflufenac muaj kev tiv thaiv thiab kho cov teebmeem, thiab muaj kev ua haujlwm zoo heev, uas tuaj yeem ua rau txhua qhov chaw ntawm lub cev cog. Txawm li cas los xij, nws txav qeeb hauv cov nroj tsuag lub cev. Vim nws qhov qeeb qeeb, nws cov nyhuv tiv thaiv zoo dua thiab nws cov nyhuv kav ntev dua! Thaum cov qoob loo siv ob zaug hauv ib lub caij cog qoob loo, lawv tsis tshua muaj mob, kev tswj xyuas yooj yim dua, cov tshuaj noj thiab cov nqi zog raug txo, thiab kev poob qis.
Cov yam ntxwv ntawm triflufenacil compounds
Nws tau nkag siab tias ntawm txhua hom tshuaj lom neeg ntawm cov khoom, pydiflumetofen muaj kev ua haujlwm siab tshaj plaws tiv thaiv nplooj ntoos thiab powdery mildew, ob hom kab mob feem ntau hauv kev ua liaj ua teb. Nws muaj txiaj ntsig zoo tiv thaiv kab mob los ntawm cov kab mob pathogenic xws li Botrytis, Sclerotinia sclerotiorum thiab Corynesporium uas nyuaj rau tswj. Qhov tshwm sim ntawm cov kab mob no yuav ua rau cov qoob loo txo qis hauv cov qoob loo xws li txiv laum huab xeeb, txiv laum huab xeeb thiab qos yaj ywm. Nws tuaj yeem tiv thaiv thiab tswj cov kab mob uas tshwm sim los ntawm Fusarium ntawm cov nplej, xws li pob txuv, thiab lwm yam. Nws yog tam sim no tsuas yog tus neeg sawv cev ntawm SDHI fungicides uas tuaj yeem tiv thaiv thiab tswj cov kab mob cab, thiab tuaj yeem txo DON co toxins. Nws tseem muaj cov txiaj ntsig kev noj qab haus huv ntawm cov nroj tsuag, muab cov nplooj ntsuab kav ntev, tiv thaiv nplooj thiab pob ntseg, thiab txhim kho cov qoob loo zoo thiab zoo.
Nyob rau tib lub sijhawm, pydiflumetofen muaj qhov ua tau zoo hauv plaub yam: dav spectrum, kev ua haujlwm siab, ua haujlwm ntev thiab ruaj khov.
Ua ntej, dav spectrum. Txij li thaum nws pib, Pydiflumetofen tau sau npe rau ntau tshaj 30 kab mob hauv ntau tshaj 100 cov qoob loo thoob ntiaj teb. Qhov tshwj xeeb N-methoxy pawg qauv hauv nws cov molecule ua rau nws muaj kev ua haujlwm zoo tiv thaiv Botrytis cinerea, Fusarium, Sclerotinia, thiab lwm yam. Nws rhuav tshem cov ciam teb ntawm SDHI fungicides thiab tuaj yeem tiv thaiv thiab tswj 60% ntawm cov kab mob qoob loo tshwj tsis yog oomycetes thiab kab mob.
Thib ob, efficiency. Cov pab pawg pyrazole amide tshwj xeeb hauv cov qauv tshuaj coj los ua kom muaj kev tiv thaiv kab mob ntau dua. Piv nrog cov fungicides zoo sib xws, kev tswj kev ua haujlwm ntawm Botrytis cinerea, Fusarium graminearum thiab Septoria yog siab dua 8 mus rau 30 npaug, thiab kev tiv thaiv kab mob yog ntau dua.
Thib peb, durability. Cov pab pawg lipophilic nyob rau hauv cov qauv tshuaj tuaj yeem ceev ceev thiab nruj nreem khi rau cov waxy txheej ntawm nplooj. 80% ntawm cov tshuaj tua kab nkag mus rau waxy txheej ntawm nplooj 6 teev tom qab thov, thiab ib qho me me nkag mus rau hauv cov nroj tsuag lub cev tib lub sijhawm. Nws muaj kev tiv thaiv zoo dua thiab tuaj yeem ua siab ntev tiv nrog ntau qhov chaw sab nraud kom ntseeg tau tias muaj kev tswj xyuas ntev dua.
Plaub, stability. Kev tiv thaiv zoo heev rau kev ntxuav dej nag. Nws tuaj yeem raug ntxuav los ntawm dej nag 1 teev tom qab thov. Lub peev xwm khaws cia ntawm cov khoom xyaw nquag yog 3 mus rau 5 npaug siab dua li cov tshuaj siv tshuaj. Qhov kev ua tau zoo yog ruaj khov nyob rau hauv ib puag ncig sib txawv.
Pydiflumetofen tsis muaj qhov cuam tshuam nrog lwm cov neeg ua haujlwm siv los tswj cov pob kws pob kws thiab yog cov tshiab nplej pob kws tsis kam tswj cov cuab yeej.
kev cia siab
Pydiflumetofen muaj toxicity tsawg, muaj kev nyab xeeb rau ib puag ncig, muaj kev ua haujlwm ntev thiab ruaj khov, thiab tuaj yeem siv los hloov lossis lwm txoj hauv kev tam sim no siv triazole thiab lwm yam fungicides, thiab muaj peev xwm siv tau zoo. Ntawm txhua hom tshuaj lom neeg ntawm cov khoom, pydiflumetofen muaj qhov ua haujlwm siab tshaj plaws tiv thaiv nplooj nplooj thiab cov kab mob mildew. Nws muaj txiaj ntsig zoo rau cov kab mob uas nyuaj rau kev tswj hwm, xws li tshwm sim los ntawm cov kab mob pathogenic xws li Botrytis, Sclerotinia sclerotiorum thiab Corynesporium. Nws kuj tseem muab kev ua tiav ntawm kev tiv thaiv thiab tswj cov kab mob tshwm sim los ntawm Fusarium ntawm cov nplej, xws li kab mob, thiab pydiflumetofen tuaj yeem ua rau cov qoob loo nce ntxiv thiab cov txiaj ntsig. Nyob rau tib lub sijhawm, pydiflumetofen molecule tsis tsuas yog tau txais txiaj ntsig ntawm pyrazole amide pawg los ntawm kev ua haujlwm siab SDHI fungicides tam sim no, tab sis kuj ua tiav cov qauv N-methoxy, yog li muab cov khoom lag luam dav dav bactericidal spectrum. Nws tuaj yeem siv rau ntau tshaj 100 cov qoob loo thiab tswj ntau dua 30 kab mob loj; tshwj xeeb, nws yog ib qho kev ua txhaum ntawm kev tiv thaiv thiab kho cov kab mob tshwm sim los ntawm Fusarium, xws li cov nplej pob kws, thiab muaj cov txiaj ntsig tseem ceeb hauv kev txo cov co toxins. Pydiflumetofen yog tam sim no tsuas yog SDHI fungicide sau npe los tswj cov pob kws pob kws.
