Difenoconazole, nrog rau cov tshuaj formula C19H17Cl2N3O3, yog cov tshuaj tua kab mob qis heterocyclic fungicide uas yooj yim soluble hauv cov kuab tshuaj organic, muaj kev txav mus los tsawg hauv av, thiab degrades maj mam. Nws yog tsuas yog siv raws li ib tug fungicide.
1. Hais txog Difenoconazole
Lub mechanism ntawm kev txiav txim ntawm Difenoconazole yog tsuas yog inhibit lub biosynthesis ntawm ergosterol nyob rau hauv pathogenic hlwb, yog li rhuav tshem cov qauv thiab kev ua haujlwm ntawm cov kab mob cell membrane thiab ua rau cov fungus tuag. Nws yog ib qho kev nyab xeeb, ua haujlwm siab, dav-spectrum, tsis tshua muaj tshuaj lom, tsis tshua muaj tshuaj fungicide nrog kev tiv thaiv, kho thiab tiv thaiv cov teebmeem thiab kev ua haujlwm. Nws yog dav siv nyob rau hauv cov txiv hmab txiv ntoo, zaub, cereals, horticultural qoob loo, thiab lwm yam. los tiv thaiv thiab tswj qhov chaw dub, nplooj ntoos, powdery mildew, thiab lwm yam.; nws kuj tseem siv tau los ua cov tshuaj kho cov noob rau cov nplej thiab pob kws los tiv thaiv thiab tswj smut, thiab lwm yam.
2. Khoom nta
(1) Broad fungicide spectrum. Difenoconazole muaj kev tswj xyuas zoo rau ntau yam kab mob tshwm sim los ntawm cov kab mob xws li ascomycetes, basidiomycetes thiab fungi tsis zoo. Nws kuj tseem muaj cov txiaj ntsig zoo ntawm cov nplej xoob smut, bunt, noj-tag nrho, powdery mildew, hauv paus rot, sheath blight, glumes, nplooj blight, xeb, beet xim av chaw, kua txob dub, powdery mildew, grape powdery mildew, txiv laum huab xeeb nplooj. qhov chaw, net chaw, qos yaj ywm thaum ntxov blight, dib powdery mildew, anthracnose, lws suav thaum ntxov blight, grape black pox, citrus scab, thiab lwm yam.
(2) Systemic conductivity. Difenoconazole muaj zog nkag mus rau hauv lub cev thiab ua haujlwm zoo heev. Nws tuaj yeem nqus tau los ntawm cov hauv paus hniav, stems thiab nplooj. Tom qab nkag mus rau hauv cov nroj tsuag lub cev, nws inhibits biosynthesis ntawm cov hlwb thiab cuam tshuam nrog kev loj hlob ntawm cov kab mob. Nyob rau tib lub sijhawm, nws tuaj yeem ua sai sai rau hauv cov nroj tsuag lub cev, tiv thaiv cov nplooj tshiab, paj thiab txiv hmab txiv ntoo los ntawm kev puas tsuaj ntawm cov kab mob. Peb tau qhia txog qhov systemicity thiab conductivity hauv kev nthuav dav thaum peb tham txog pyraclostrobin, yog li peb yuav tsis rov hais dua ntawm no.
(3) Zoo sib xws. Cov ntaub ntawv tseem ceeb ntawm Difenoconazole suav nrog 92%, 95%, 97% technical, 10%, 15%, 20%, 30%, 60% dej dispersible granules, 10%, 20%, 25%, 30% microemulsion, 5% 10%, 20%, 25% dej emulsion, 30 g / L tshem tawm cov noob txheej, 25%, 30% emulsifiable concentrate, 10%, 25%, 30%, 40% suspension, 10%, 30% wettable hmoov, thiab lwm yam .
Difenoconazole tuaj yeem sib xyaw nrog cov tshuaj fungicides thiab tshuaj tua kab xws li propiconazole, azoxystrobin, carbendazim, methyl thiophanate, fludioxonil, kresoxim-methyl, prochloraz, epixiconazole, metalaxyl-M, hexaconazole, mancozeb, imazalil, cyideproinstrobin, hydrochloride, imazalil azole, jinggangmycin, thiophanate-methyl, thiophanate-methyl, tebuconazole, pyrimidine nucleoside tshuaj tua kab mob, thiram, imidacloprid, bromothionil, thiamethoxam, thiab lwm yam. Nws tuaj yeem siv los tsim cov tshuaj fungicides thiab cov tshuaj kho cov noob. Tam sim no, muaj ntau dua 450 cov khoom lag luam sau npe.
Cov tshuaj uas muaj txiaj ntsig zoo thiab siv dav suav nrog benzoyl·azoxystrobin, benzoyl·propiconazole, benzoyl·pyraclostrobin, thiab lwm yam, nrog rau cov tshuaj kho cov noob xws li benzoyl·imidacloprid, pyrimidine·pyraclostrobin·benzoyl, phenoxy·pyraclostrobin· thiamethoxam, thiab lwm yam. .
(4) Resistant los nag yaig thiab kev nyab xeeb zoo. Nws muaj kev nyab xeeb zoo. Tus neeg sawv cev adhered rau nplooj nplooj yog resistant rau nag yaig, thiab nws evaporates tsawg heev los ntawm nplooj. Nws muaj cov kab mob fungicide ntev ntev txawm tias nyob rau hauv qhov kub thiab txias, uas yog 3 mus rau 4 hnub ntev dua li cov kab mob fungicides.
Ntau qhov sib txawv ntawm Difenoconazole thiab pyraclostrobin:
Pyraclostrobin yog methoxyacrylate fungicide, thiab difenoconazole belongs rau triazole fungicide;
Hom kev ua ntawm pyraclostrobin yog inhibit mitochondrial respiration, ua rau cell tuag, yog li ua tiav lub hom phiaj ntawm sterilization. Difenoconazole inhibits biosynthesis ntawm ergosterol hauv cov kab mob pathogenic, rhuav tshem cov qauv thiab kev ua haujlwm ntawm cov kab mob kab mob ntawm tes, thiab ua rau cov kab mob fungal tuag, yog li ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam;
Txawm hais tias ob qho tib si yog dav-spectrum fungicides, lawv tseem muaj kev sib txawv ntawm kev tiv thaiv thiab tswj cov kab mob.
3. Scope ntawm daim ntawv thov

(4) Kev siv. Los ntawm cov ntsiab lus saum toj no, peb tau pom meej tias difenoconazole tuaj yeem siv los tswj ntau yam kab tsuag. Tsis tas li ntawd, muaj ntau yam khoom uas muaj ntau hom tshuaj thiab cov ntsiab lus sib txawv. Nws yog ib qho nyuaj rau piav qhia txog cov kev qhia tshwj xeeb thiab ntau npaum li cas rau cov qoob loo sib txawv, ntau theem, thiab cov kab mob sib txawv. Koj tuaj yeem kho qhov ntau npaum li cas raws li cov lus pom zoo ntawm lub pob. Nov yog qee cov qauv siv yooj yim:
Nyob rau theem pib ntawm tus kab mob, siv cov tshuaj tsawg tsawg, thiab lub caij nyoog ntawm ntau daim ntawv thov tuaj yeem txuas ntxiv kom tsim nyog;
Thaum tus kab mob hnyav, siv ntau npaum li cas nrog lub sijhawm luv luv;
Thaum lub sij hawm muaj kab mob sib kis thaum cov nroj tsuag loj hlob zuj zus, qhov kub thiab txias yog qhov tsim nyog, cov av noo siab, thiab muaj nag ntau, kev siv ntau npaum li cas tuaj yeem siv rau lub sijhawm luv luv, thiab cov ntawv thov tuaj yeem nce ntxiv kom ntseeg tau. cov nyhuv ntawm kev tiv thaiv kab mob thiab tawm los nce.
4. Ceev faj
(1) Difenoconazole yuav tsum tau siv thaum ntxov li sai tau, thiab tshuaj tsuag yuav tsum tau nqa tawm thaum ntxov ntawm tus kab mob kom tau txais txiaj ntsig zoo tshaj plaws.
(2) Difenoconazole yuav tsum tsis txhob tov nrog tooj liab npaj. Yog hais tias nws yog tsim nyog los sib tov nws nrog tooj liab npaj, qhov ntau npaum ntawm difenoconazole yuav tsum tau nce los ntawm ntau tshaj 10%, thiab tus nqi ntawm cov dej siv thaum txau yuav tsum txaus.
(3) Nws raug nquahu kom sib xyaw nrog lwm cov tshuaj fungicides, xws li propiconazole, azoxystrobin, pyraclostrobin, tebuconazole, methyl thiophanate, jinggangmycin, thiab zhongshengmycin. Kev sib xyaw tuaj yeem nthuav dav cov kab mob fungicide thiab txhim kho kev sib koom ua ke.
(4) Tsis txhob siv ntau tshaj 3 zaug hauv ib lub caij qoob loo. Tsis txhob siv ntau dhau los yog tsim txom nws. Nws yog khoom muaj nqis tsuas yog thaum siv kom raug.
