MANCOZEB: Ib phau ntawv qhia dav dav rau nws cov kev siv, cov txiaj ntsig, thiab kev nyab xeeb hauv kev nyab xeeb niaj hnub

MANCOZEB yog kev sib koom ua ke ntawm manganese thiab zinc ntsev ntawm ethylene bisdithiocarbamate (c₈h₁₂mnnn₄s₈zn). Nws zoo li cov xim daj lossis greyish hmoov insoluble hauv dej thiab feem ntau cov kuab tshuaj organic. Cov compound degrades thaum nthuav tawm cov acids, alkalis, siab, huab cua}}, xav tau chaw ntim khoom txias, ziab, airtight. Raws li qhov dav -} spectrumKev Tiv Thaiv Kev Tiv Thaiv, Mangozeb ua haujlwm los ntawm ntau -}} site site inhibition. Thaum muaj kev sib cuag nrog ya raws thiab huab cua, nws hloov mus rau ethanocyanate) sulfide (ebis), uas yuav tawg ntxiv mus rau ethyleneisiscyanate (EBI) hauv UV teeb. Cov tebchaw no cuam tshuam kev fungal metabolism los ntawmInhibiting PyRuvate oxidation, uas cuam tshuam kev ua pa ntawm tes thiab lub zog muaj zog nyob rau ntawm rau qhov chaw sib txawv. Lub tshuab complex no ua pathogen tsis zoo li tsis zoo li tsis pom zoo, tsim mangozebb ua lub pob zeb hauv- Cov tswv yim fungal.

Mancozeb zoo tiv thaiv ntau cov qoob loo muaj ntau yam txiv hmab txiv ntoo, zaub, cereals, thiab tubers. Nws tswj hwm ntau dua 400 fungal pathogens, xws liPhytophthora, Alternaria, thiabColletotrichumhom. Cov ntawv thov tseem ceeb muaj xws li:

• Zaub thiab txiv hmab txiv ntoo: Tswj cov txiv lws suav thaum ntxov (80% kev ua tau zoo blight (90% kev ua tau zoo blight Cov nqi thov feem ntau ntau los ntawm 300-600 × dilution (70-80% wettable hmoov) ntawm 7-14-hnub sib nrug.
• Kev kho cov noob: Siv nyob rau ntawm 0.1% -0.5% cov noob hnyav kom txwv av- boon - tawm hauv zaub.
• Kab mob -} Cov txheej txheem tshwj xeeb: Rau Strawberry anthracnose, A 350 × dilution ntawm 20% WP raug pom zoo; Rau Apple nplooj nplooj ntoo nplooj ntoo, 400-600 × tshuaj tiv thaiv thaum lub sijhawm muaj mob ua tau zoo.

Tshaj dhau tus kab mob kev tswj hwm, lub manganese thiab zinc micronutrients hauv Mancozowb txhim khoPhotosynthesis, enzyme ua kom lub zog, thiab qoob loo heev, tsis ncaj qha txhim kho cov txiaj ntsig thiab qhov zoo.

MANCOZEB muajTsawg toxicity (LD₅₀ >7,000 mg / kg hauv nas) nrog tsis muaj pov thawj ntawm kev sib cav los yog Teratogenicity ntawm cov koob tshuaj pom zoo. Txawm li cas los xij, nws tuaj yeem distriction nqaij daim tawv thiab cov plaub hau thiab cov hnab looj tes, ntsej muag, kev nyiam huv si tom qab kov. Kev txhawj xeeb ib puag ncig muaj xws li:

• Neeg muaj plaub hau: Lub 48-teev TLM rau carp yog 4.0 mg / l, tsim nyog affer aav nyob ze dej lub cev.
• Residue kev tswj hwm: Cov lus seem feem ntau ua haujlwm qis dua qhov siab tshaj plaws (mRLS) tsis pub dhau 7-15 hnub. Ua ntej - sau cov sib nrug (pis) ntawm 5-15 hnub rau cov qoob loo xws li txiv lws suav thiab txiv hmab ua raws li cov qauv kev nyab xeeb.

Txhawm rau tiv thaiv kom tsis kam mus rau cov fungicides, Mancountb feem ntau ua ke nrog cov khoom xyaw nquag nyiammyClobutanil(piv txwv li, 62.25% "systhane - mz") lossisciniconazole(xws li, 32.5% tus zinc · capanonazole wp). Cov mixtures sib xyaw ua ke thiab cov peev xwm curative, nthuav dav lub spectrum thiab txuas cov txiaj ntsig zoo. Cov qauv tshiab niaj hnub xws li chelated 80% WPS lossis 75%}}}}}}}} - chelated versions.

Mancozowb tseem ceeb nyob hauv ntiaj teb ua liaj ua teb vim nwsTus nqi - ua tau zoo, multi -} chaw ntawm kev ua tau zooCov. Ua raws li kev tswj hwm kev sib xyaw ua ke (IPM) cov ntsiab cai {}}} maximizes qoob loo ib puag ncig thaum muaj kev cuam tshuam ib puag ncig qoob loo. Raws li kev ua liaj ua teb cov nyom evolve nrog Dietistries thiab Precision Daim Ntawv Thov Technologies yuav tswj hwm nws qhov tseem ceeb hauv kev nyab xeeb zaub mov. Cov neeg ua liaj ua teb thiab agronomists yuav tsum ua raws cov lus qhia kab ntawv, thiab anti {{}}}} cov tswv yim kuj siv cov laj thawj funegicing no.
