Propiconazole systemic wide aikace-aikace triazole fungicide
Bayanin samfur
Propiconazole wani nau'in fungicides ne na triazole, ana amfani dashi da yawa a aikace-aikace iri-iri.Ana amfani da shi akan ciyawa da ake shuka iri, namomin kaza, masara, shinkafar daji, gyada, almonds, dawa, hatsi, pecans, apricots, peaches, nectarines, plums da prunes.A kan hatsi yana sarrafa cututtukan da Erysiphe graminis ke haifarwa, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides, Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, da Septoria spp.
Yanayin aikin Propiconazole shine demethylation na C-14 a lokacin ergosterol biosynthesis (ta hanyar hana ayyukan 14a-demethylase kamar yadda aka bayyana a ƙasa), kuma yana haifar da tarawar C-14 methyl sterols.Biosynthesis na waɗannan ergosterols yana da mahimmanci ga samuwar ganuwar tantanin halitta na fungi.Wannan rashin samar da sterol na yau da kullun yana rage jinkiri ko dakatar da ci gaban naman gwari, yadda ya kamata ya hana ƙarin kamuwa da cuta da/ko mamaye kyallen jikin runduna.Sabili da haka, ana ɗaukar propiconazole azaman fungistatic ko haɓaka haɓaka maimakon fungicidal ko kisa.
Propiconazole kuma shine mai hana Brassinosteroids biosynthesis.Brassinosteroids (BRs) su ne poly-hydroxylated steroidal hormones tare da tasiri mai zurfi akan yawancin amsawar tsire-tsire.Suna da hannu wajen daidaitawa da haɓakar ƙwayoyin cuta da rarrabawa, bambance-bambancen jijiyoyin jini, photomorphogenesis, ƙwanƙwasa kusurwar ganye, ƙwayar iri, haɓakar stomata, da kuma kawar da ƙwayar ganye da abscission.
Propiconazole (PCZ) yana cikin mafi yawan amfani da su a aikin gona.Triazole fungicides suna da gajeriyar rabin rayuwa da ƙananan bioaccumulation fiye da magungunan kashe qwari na organochlorine, amma illa ga muhallin ruwa na iya tasowa daga ɗigon feshi ko ƙasa bayan ruwan sama.An ba da rahoton cewa suna fuskantar canji zuwa na biyu metabolites a cikin dabbobi masu shayarwa na ƙasa.
Propiconazole yana shiga cikin yanayin ƙasa a cikin aikinsa a matsayin fungicide don amfanin gona iri-iri.A cikin yanayin ƙasa, ana gabatar da propiconazole don zama ɗan tsayin daka don ci gaba.Biotransformation wata hanya ce mai mahimmanci ta canji don propiconazole, tare da manyan samfurori na canzawa sune 1,2,4-triazole da mahadi hydroxylated a cikin dioxolane moiety.Phototransformation a kan ƙasa ko a cikin iska ba shi da mahimmanci ga canjin propiconazole.Propiconazole ya bayyana yana da matsakaici zuwa ƙananan motsi a cikin ƙasa.Yana da yuwuwar isa ga ruwan ƙasa ta hanyar leaching, musamman a cikin ƙasa mai ƙarancin abun ciki na kwayoyin halitta.Propiconazole yawanci ana gano shi a cikin shimfidar ƙasa na sama, amma an gano samfuran canji cikin zurfi a cikin bayanan ƙasa.
