Fluoxapyr ndi carboxamidefungicideyopangidwa ndi BASF. Ili ndi ntchito zabwino zopewera komanso zochizira. Amagwiritsidwa ntchito popewa komanso kuwongolera matenda oyamba ndi fungus, pafupifupi mitundu 26 ya matenda oyamba ndi fungus. Itha kugwiritsidwa ntchito pa mbewu pafupifupi 100, monga mbewu zambewu, nyemba, mbewu zamafuta, mtedza, mitengo yazipatso ya pome ndi miyala, masamba ndi masamba a tuber, masamba a zipatso ndi thonje, masamba kapena mbewu. Fluoxafenamide ndi succinate dehydrogenase inhibitor komanso fungicide yabwino kwambiri yopangidwa m'zaka zaposachedwa.

Khola munjira yamadzi pa pH 4, 5, 7, 9 mumdima komanso wosabala. Kuunikira kuli kokhazikika.
Kuopsa kwa Fluoxafen
Kuopsa kwapakamwa pakamwa pa makoswe (azimayi) a mankhwala oyambirira a fluconazole: LD50≥2,000 mg/kg, kawopsedwe ka pachimake pa makoswe (amuna ndi akazi): LD50> 2,000 mg/kg, chiwopsezo chakupha kwa makoswe (amuna ndi akazi): LC.51 mg/L; kukwiya pang'ono kwa maso a kalulu ndi khungu la akalulu; palibe tcheru ku Guinea nkhumba khungu. Palibe carcinogenicity, palibe teratogenicity, palibe zotsatirapo pa kubereka, palibe genotoxicity, neurotoxicity ndi immunotoxicity.
Kuopsa koopsa kwa mbalame LD50＞2,000 mg/kg, kuopsa kwa Daphnia 6.78 mg/L (48 h), kuopsa kwa nsomba (96 h) LC50 0.546 mg/L, kawopsedwe koopsa kwa zamoyo zam'madzi zopanda msana (48 h), algae80 mg EC50. (72 h) EC50 0.70 mg/L, kukhudzana pachimake kawopsedwe ku njuchi (48 h) LD50>100 μg/njuchi, pachimake mkamwa kawopsedwe kwa njuchi (48 h) LD50>110.9 μg/njuchi, pachimake kawopsedwe kwa earthworms>10 mg/10 LC masiku 10 LC0. Kuchokera pazomwe zili pamwambazi, zikhoza kuwoneka kuti Fluoxafen ndi poizoni kwa zamoyo zam'madzi ndipo imakhala ndi poizoni wochepa kwa zamoyo zina zopindulitsa.
Njira yogwiritsira ntchito fluoxafen
Fluoxafenamide ndi succinate dehydrogenase inhibitor, yomwe imagwira ntchito pa succinate dehydrogenase mu mitochondrial kupuma unyolo II kuletsa ntchito yake, potero kuletsa kumera kwa fungal tizilombo toyambitsa matenda spores, kukula kwa machubu majeremusi ndi mycelium.
Zinthu zowongolera Fluconazole
Fluoxamid ndiyothandiza kwambiri, sipekitiramu yotakata, yokhazikika, yosankha, imakhala ndi machitidwe abwino kwambiri, ndipo imalimbana ndi kukokoloka kwa mvula. Imatha kuwononga mbewu monga chimanga, soya, chimanga, mbewu za rapese, mitengo yazipatso, masamba, ndi ma beets a shuga kudzera m'masamba ndi mbewu. , mtedza, thonje, udzu ndi mbewu zapadera, etc., monga mbewu, soya, mitengo yazipatso ndi ndiwo zamasamba zomwe zimayambitsidwa ndi Concha, Botrytis cinerea, Powdery mildew, Cercospora, Puccinia, Rhizoctonia, Sclerotium Matenda oyambitsidwa ndi bowa, botrytis cinerea, dzimbiri, matenda a mpendadzuwa wa mpendadzuwa zoyambitsidwa ndi Alternaria, ndi zina. Zolembetsedwa kuti zigwiritsidwe ntchito pazomera zopitilira 70 pofika chaka cha 2015, BASF ikufuna kulembetsa kuti igwiritsidwe ntchito pazomera zopitilira 100.
Fluoxafen imasinthasintha kwambiri, ndipo pali mitundu yambiri yazogulitsa. Adexar (fluconazole + epoxiconazole) amagwiritsidwa ntchito mu tirigu, balere, triticale, rye ndi oats kuti athetse powdery mildew, choipitsa masamba, glume blight, dzimbiri lamizere ndi tsamba. Priaxor (flufenapyr + pyraclostrobin) amalembetsedwa ku United States chifukwa cha soya, phwetekere, mbatata ndi mbewu zina zakumunda, ndipo ali ndi zotsatira zapadera pakuwongolera malo a soya bulauni (Septoria glycines); Orkestra SC (flufenapyr + Pyraclostrobin) amalembetsedwa ku Brazil soya, malalanje, mbatata, anyezi, kaloti, maapulo, mango, mavwende, nkhaka, tsabola belu, tomato, canola, mtedza, nyemba za impso, mpendadzuwa, manyuchi, chimanga, tirigu ndi maluwa a rose, somum canola ndi maluwa ku Asia dzimbiri, kulimbikitsa photosynthesis ya mbewu, ndi kugwiritsidwa ntchito posamalira matenda. Priaxor D (flufenapyr + pyraclostrobin + tetraflufenazole) amalembetsedwa ku United States pofuna kupewa komanso kuwongolera mawanga a soya imvi omwe sagonjetsedwa ndi methoxyacrylate fungicides. Obvius wothandizira mbewu (flufenapyr + pyraclostrobin + metalaxyl) amalembetsedwa ku United States ndipo amatha kuwongolera matenda osiyanasiyana a mbewu zambiri.
Ma fungicides a succinate dehydrogenase inhibitor akula kwambiri m'zaka zaposachedwa, ndipo fluoxamid ndiye chinthu chotsogola chamtundu uwu wa fungicides, chifukwa chakuchita bwino kwake, mawonekedwe ake, machitidwe adongosolo, oyenera mbewu zosiyanasiyana ndi mawonekedwe ena, makamaka, kukulitsa kosalekeza kwa zinthu zake zapawiri kwakulitsa mawonekedwe owongolera komanso kukula kwa msika wamafuta opangira bowa.
