Maitiro ekuita kwe fluoxafen
Fluoxafenamide inodzivirira dehydrogenase, inoshanda pa succinate dehydrogenase iri mu mitochondrial respiratory chain complex II kudzivirira kushanda kwayo, nokudaro ichidzivisa kumera kwefungus pathogen spores, kukura kwemachubhu ezvipembenene uye mycelium.
Zvinhu zvekudzora Fluconazole
Fluoxamid inoshanda zvikuru, ine mativi akasiyana-siyana, inogara kwenguva refu, inosarudzira, ine mafambiro akanaka emvura, uye inodzivirira kukurwa kwevhu nemvura. Inogona kudzora zvinobudirira zviyo, soya, chibage, mhodzi dzerape, miti yemichero, miriwo, uye beetroot kuburikidza nekurapa mashizha nembeu. , nzungu, donje, uswa nezvimwe zvirimwa zvakakosha, nezvimwewo, zvakaita sezviyo, soya, miti yemichero nemiriwo zvinokonzerwa neConcha, Botrytis cinerea, Powdery mildew, Cercospora, Puccinia, Rhizoctonia, Sclerotium Zvirwere zvinokonzerwa nefungus, botrytis cinerea, ngura, powdery mildew yembeu, donje blight, sunflower nezvirwere zverapeseed zvinokonzerwa neAlternaria, nezvimwewo. BASF yakanyoreswa kushandiswa pazvirimwa zvinopfuura 70 panosvika gore ra2015, ine chinangwa chekunyoresa kushandiswa pazvirimwa zvinopfuura 100.
Fluoxafen inogona kuchinjika zvakanyanya, uye kune mhando dzakawanda dzezvigadzirwa zvinosanganiswa. Adexar (fluconazole + epoxiconazole) inoshandiswa mugorosi, bhari, triticale, rye neoats kudzora powdery mildew, leaf blight, glume blight, stripe rust uye leaf rust. Priaxor (flufenapyr + pyraclostrobin) yakanyoreswa muUnited States yesoya, domasi, mbatatisi nezvimwe zvirimwa zvemumunda, uye ine simba rakakosha pakudzivirira soya brown spot (Septoria glycines); Orkestra SC (flufenapyr + Pyraclostrobin) yakanyoreswa muBrazil yesoya, citrus, mbatatisi, hanyanisi, makarotsi, maapuro, mango, manwiwa, magaka, bell pepper, madomasi, canola, nzungu, kidney beans, sunflower, sorghum, chibage, gorosi nemaruva (Chrysanthemum nerose), nezvimwewo, inogona kudzora Asian soya ngura, kuwedzera photosynthesis yezvirimwa, uye kushandiswa pakudzivirira zvirwere. Priaxor D (flufenapyr + pyraclostrobin + tetraflufenazole) yakanyoreswa muUnited States kudzivirira nekudzivirira madonhwe e soya asingabatwe nemishonga inouraya fungi ye methoxyacrylate. Mushonga wekurapa mbeu weObvius (flufenapyr + pyraclostrobin + metalaxyl) wakanyoreswa muUnited States uye unogona kudzora zvirwere zvakasiyana-siyana zvembeu dzisingabatwe nembeu dzezvirimwa zvakawanda.
Mishonga yefungi inorwisa dehydrogenase inhibitor yakura nekukurumidza mumakore achangopfuura, uye fluoxamid ndiyo inotungamira mumhando iyi yemishonga yefungi, nekuda kwekushanda kwayo kwepamusoro, broad spectrum, systemic activity, yakakodzera zvirimwa zvakasiyana-siyana nezvimwe zvinhu. Kunyanya, kukura kuri kuramba kuchienderera mberi kwezvigadzirwa zvayo zvakasanganiswa kwakawedzera control spectrum uye chiyero chezvirimwa zvinoshandiswa, uye kwave chinhu chinopenya mumusika wemishonga yefungi.
