Difenoconazole triazole yakakura-spectrum fungicide yekudzivirira goho
Chigadzirwa tsananguro
Difenoconazole rudzi rwetriazole-mhando fungicide.Mushonga unouraya fungidziri unoshanda wakakura-siyana, uchidzivirira goho uye kunaka nekuisa mashizha kana kurapwa kwembeu.Zvinotora kushanda kuburikidza nekuita se inhibitor ye sterol 14α-demethylase, ichivhara biosynthesis ye sterol.Kuburikidza nekuvharira sterol biosynthesis process, inotadzisa mycelia kukura uye kumera kwehutachiona ne spores, pakupedzisira kudzvanyirira kuwanda kwefungi.Difenoconazole yakashandiswa zvakanyanya muzvirimwa zvakawanda munyika dzakawanda nekuda kwekukwanisa kwayo kudzora zvirwere zvakasiyana-siyana zvefungal.Ndiyo imwe yemishonga yakakosha uye inoshandiswa zvakanyanya-inoshandiswa pakudzivirira zvirwere mumupunga.Inopa basa rinogara kwenguva refu uye rekurapa rinopesana neAscomycetes, Basidiomycetes uye Deuteromycetes.Inoshandiswa kurwisa zvirwere zvemazambiringa, pome michero, muchero wematombo, mbatatisi, shuga beet, kubatwa kwemafuta, mabhanana, zvishongo uye zvirimwa zvakasiyana siyana zvemiriwo.Inoshandiswawo semushonga wembeu kurwisa huwandu hwehutachiona hwegorosi nebhari.Mugorosi, mashizha ekutanga efoliar padanho rekukura 29-42 anogona kukonzera, mune mamwe mamiriro ezvinhu, chlorotic spotting yemashizha, asi izvi hazvina mhedzisiro pagoho.
Kune mashoma akaburitswa ruzivo nezve metabolism ye difenoconazole.Inopera zvishoma nezvishoma muvhu, uye metabolism mumiti inosanganisira kuputika kwekubatana kwe triazole kana kuti oxidation ye phenyl ring inoteverwa nekugadzirisa.
Environmental Fate:
Mhuka: mushure mekutonga nemuromo, difenoconazole yakakurumidza kubviswa zvachose, neweti uye tsvina.Zvisaririra mumatishu hazvina kukosha uye pakanga pasina humbowo hwekuunganidza.Kunyangwe ingangoita mobile molecule haigone kudonha nekuda kwekudzika kwayo kunyungudika kwemvura.Zvisineyi zvine mukana wekutakura zvidimbu zvidiki.Iyo inoputika zvishoma, inopfuurira muvhu uye munzvimbo yemvura.Pane zvimwe zvinonetsa maererano nekugona kwayo kuita bioaccumulation.Iyo ine muchetura zvine mwero kuvanhu, mhuka dzinoyamwisa, shiri uye zvipenyu zvakawanda zvemumvura.
