Cov kab mob qoob loo thiab kab kab kab yog qhov tseem ceeb txwv tsis pub muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo. Kev tswj tshuaj tua kab yog qhov ceev tshaj plaws thiab zoo tshaj plaws los tswj cov kab mob. Xaiv cov fungicides zoo heev yog qhov yuav tsum tau ua ua ntej rau kev tswj cov kab mob. Niaj hnub no kuv pom zoo kom muaj cov tshuaj fungicide zoo heev uas tuaj yeem tiv thaiv thiab kho ntau yam kab mob, ntxiv cov kab mob, txhim kho qoob loo photosynthesis, thiab txhim kho cov kab mob tiv thaiv.
1. Cov qauv qhia
Cov tshuaj tua kab mob no yog azomethine·mantiazole, uas yog cov tshuaj tua kab mob ua los ntawm 55% mantiazole thiab 5% pyraclostrobin. Mantiazole yog ib qho kev tiv thaiv dav-spectrum fungicide tsim los ntawm mancozeb nrog kev nyab xeeb zoo, zinc cov ntsiab lus siab (18% zinc), thiab cov nyhuv ntev. Nws kov yeej qhov tsis zoo ntawm mancozeb tias nws yooj yim ua rau phytotoxicity, nce cov ntsiab lus ntawm zinc ions, thiab muaj kev tiv thaiv zoo ntawm ntau yam kab mob xws li pear dub chaw, txiv apple nplooj, zaub blight, downy mildew, thiab teb qoob loo. xeb.
Nyob rau tib lub sijhawm, nws tuaj yeem ntxiv cov zinc ntau ntxiv, nce cov nplooj photosynthesis ntawm nplooj, ua kom cov nplooj ntau ntom thiab ntsuab, thiab muaj zog tiv thaiv kab mob; pyraclostrobin yog qhov zoo tshaj plaws broad-spectrum methoxyacrylate fungicide tsim thaum pib ntawm lub xyoo pua no. Nws yog ib qho mitochondrial respiration inhibitor nrog muaj zog permeability thiab kev ua haujlwm zoo. Nws muaj cov teebmeem ntawm kev tiv thaiv, tiv thaiv, kho thiab tshem tawm ntau yam kab mob los ntawm ntau yam kab mob xws li flagellates, fungi tsis zoo, basidiomycetes, thiab ascomycetes. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txhawb kev loj hlob, nce tawm los thiab txhim kho kom zoo.
2. Cov yam ntxwv tseem ceeb
(1) Broad fungicide spectrum: Cov mis no tuaj yeem tiv thaiv thiab tswj ntau yam kab mob los ntawm ntau yam kab mob xws li cov kab mob tsis zoo, flagellates, basidiomycetes, thiab ascomycetes, xws li mildew, anthracnose, vine blight, blight, ntxov blight, lig blight. , powdery mildew, fusarium taub hau blight, xeb, nplooj chaw, xim av, lub hom phiaj, thiab lwm yam. (2) Kev kho mob zoo: Cov mis no muaj zog permeability thiab zoo systemic absorption. Tom qab txau, nws tuaj yeem nqus tau sai los ntawm stems thiab nplooj thiab xa mus rau txhua qhov chaw ntawm cov qoob loo. Nws muaj kev tiv thaiv, tiv thaiv, kho thiab tshem tawm cov teebmeem ntawm ntau yam kab mob.
(3) Cov nyhuv ntev ntev: Cov mis no tuaj yeem nqus tau los ntawm cov hauv paus hniav, stems thiab nplooj ntawm cov qoob loo thiab nyob twj ywm hauv lub cev qoob loo rau lub sijhawm ntev. Nws yog resistant rau nag yaig thiab muaj ib tug kav ntev ntawm ntau tshaj 15 hnub. Yog tias siv cov noob hnav khaub ncaws, cov nyhuv kav ntev tuaj yeem ntev li ntau tshaj 50 hnub.
(4) Kev nyab xeeb zoo: Cov mis no kov yeej qhov tsis zoo uas pyraclostrobin nquag ua rau phytotoxicity rau qee cov qoob loo. Nws muaj kev nyab xeeb rau cov qoob loo thiab txhim khu kev qha ntau dua rau kev siv.
(5) Kev siv ntau yam: Cov mis no tuaj yeem siv dav hauv cov khoom noj xws li nplej, nplej, thiab pob kws, roj qoob loo xws li taum pauv, txiv laum huab xeeb, thiab rapeseed, zaub qoob loo xws li dib, txiv lws suav, thiab kua txob, txiv hmab txiv ntoo. xws li txiv apples, pears, txiv duaj, thiab txiv nkhaus taw, nrog rau cov khoom siv tshuaj hauv Suav teb thiab paj.
(6) Tswj kev loj hlob: Methotrexate yog nplua nuj nyob rau hauv cov nroj tsuag tseem ceeb cov as-ham (zinc), uas yuav txhawb chlorophyll synthesis, txhim kho nplooj vitality, thiab txhim kho qoob loo photosynthesis. Pyraclostrobin tuaj yeem txhawb cov qoob loo nitrogen nqus, txhim kho qoob loo, thiab pab txhim kho qoob loo zoo thiab tawm los. Ua kom tus nqi ntawm nplooj photosynthesis thiab txhim kho cov nroj tsuag kev nyuaj siab.
3. Lub hom phiaj ntawm kev tswj hwm
Nws tuaj yeem tswj tau ntau yam kab mob fungal xws li powdery mildew, black spot, nplooj nplooj, xim av, downy mildew, blight, anthracnose, vine blight, sooty pwm, nplooj ntoos, nplhaib rot, kab mob snowflake, kab mob dub ntawm daim tawv nqaij, fusarium taub hau blight. , xim av chaw, thaum ntxov blight, lig blight, blight, downy mildew, thiab lwm yam.
