Difenoconazole triazole wide-spectrum fungicides pofuna kuteteza mbewu
Mafotokozedwe Akatundu
Difenoconazole ndi mtundu wa triazole fungicide.Ndi mankhwala ophera bowa omwe amagwira ntchito zosiyanasiyana, kuteteza zokolola ndi khalidwe lawo pogwiritsa ntchito masamba kapena kuchiritsa mbewu.Zimayamba kugwira ntchito ngati inhibitor ya sterol 14α-demethylase, kutsekereza biosynthesis ya sterol.Kupyolera mu kuletsa njira ya sterol biosynthesis, imalepheretsa kukula kwa mycelia ndi kumera kwa tizilombo toyambitsa matenda ndi spores, pamapeto pake kupondereza kuchuluka kwa bowa.Difenoconazole yakhala ikugwiritsidwa ntchito kwambiri muzomera zosiyanasiyana m'mayiko ambiri chifukwa cha mphamvu zake zowononga matenda osiyanasiyana a fungal.Komanso ndi imodzi mwazinthu zofunika kwambiri komanso zogwiritsidwa ntchito kwambiri polimbana ndi matenda mumpunga.Amapereka ntchito zokhalitsa komanso zochizira motsutsana ndi Ascomycetes, Basidiomycetes ndi Deuteromycetes.Amagwiritsidwa ntchito polimbana ndi matenda a mphesa, zipatso za pome, zipatso zamwala, mbatata, beet shuga, kugwiriridwa kwamafuta, nthochi, zokongoletsera ndi mbewu zosiyanasiyana zamasamba.Amagwiritsidwanso ntchito ngati mankhwala ochizira mbewu motsutsana ndi tizilombo toyambitsa matenda osiyanasiyana mu tirigu ndi balere.Mu tirigu, masamba oyambilira akamakula pamlingo wa 29-42 angayambitse, nthawi zina, mawanga a masamba a chlorotic, koma izi sizikhudza zokolola.
Pali chidziwitso chochepa chomwe chasindikizidwa pa metabolism ya difenoconazole.Imatayidwa pang'onopang'ono m'nthaka, ndipo kagayidwe kazakudya m'zomera kumaphatikizapo kuphulika kwa kulumikizana kwa triazole kapena kutsekemera kwa mphete ya phenyl ndikutsata.
Tsogolo Lachilengedwe:
Zinyama: Pambuyo pakamwa, difenoconazole idachotsedwa mwachangu mpaka kwathunthu, ndi mkodzo ndi ndowe.Zotsalira mu minofu sizinali zofunikira ndipo panalibe umboni wokwanira kudzikundikira.Ngakhale mwina molekyulu yam'manja ndiyokayikitsa kutsika chifukwa cha kusungunuka kwake kwamadzi.Komabe ili ndi kuthekera koyendera ma particle bound transport.Imasinthasintha pang'ono, imalimbikira munthaka komanso m'malo amadzi.Pali zodetsa nkhawa za kuthekera kwake kwa bioaccumulation.Ndiwowopsa kwambiri kwa anthu, nyama zoyamwitsa, mbalame ndi zamoyo zambiri zam'madzi.
