Propiconazole systemic wide application triazole fungicide
Chigadzirwa tsananguro
Propiconazole imhando ye triazole fungicide, inoshandiswa zvakanyanya mumhando dzakasiyana dzekushandisa.Inoshandiswa pahuswa hunorimwa mbeu, howa, chibage, mupunga wemusango, nzungu, maamondi, mhunga, mapfunde, mapecans, maapricots, mapichisi, nectarines, plums nemaprunes.Pazviyo inodzora zvirwere zvinokonzerwa neErysiphe graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides, Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, uye Septoria spp.
Propiconazole's mode of action is demethylation yeC-14 panguva yeergosterol biosynthesis (kuburikidza nekudzivisa basa re14a-demethylase sezvinotsanangurwa pasi apa), uye zvichiita kuti kuunganidzwa kweC-14 methyl sterols.Iyo biosynthesis yeiyi ergosterol yakakosha pakuumbwa kwesero madziro efungi.Uku kushaikwa kweyakajairwa kugadzirwa kwe sterol kunononoka kana kumisa kukura kwefungus, kudzivirira nekudzivirira humwe hutachiona uye / kana kupinda kweanotambira tishu.Naizvozvo, propiconazole inoonekwa sefungistatic kana kukura inhibiting pane fungicidal kana kuuraya.
Propiconazole zvakare ine simba inhibitor yeBrassinosteroids biosynthesis.Brassinosteroids (BRs) i-poly-hydroxylated steroidal mahomoni ane mhedzisiro yakadzama pane akati wandei physiological chirimwa mhinduro.Ivo vanobatanidzwa mukugadzirisa sero elongation uye kupatsanura, vascular differentiation, photomorphogenesis, leaf angle inclination, mbeu kumera, kukura kwestomata, pamwe nekudzvinyirirwa kwemashizha senescence uye abscission.
Propiconazole (PCZ) iri pakati pezvinonyanya kushandiswa mukurima.Triazole fungicides ine hafu yeupenyu hupfupi uye yakaderera bioaccumulation pane organochlorine mishonga yezvipembenene, asi zvinokanganisa pane ecosystem yemvura inogona kumuka kubva mukudonha kwepfapfaidzo kana kuyerera kwemvura mushure mekunaya kwemvura.Ivo vanonzi vachashandurwa kune yechipiri metabolites mumhuka dzepasi.
Propiconazole inopinda munharaunda yepasi mukushanda kwayo semushonga wefungi kune zvakasiyana siyana zvezvirimwa.Munharaunda yepasi, propiconazole inoratidzwa kuti irambe ichienderera mberi.Biotransformation inzira yakakosha yekushandurwa kwepropiconazole, ine michina mikuru yekushandura iri 1,2,4-triazole uye macompounds hydroxylated pa dioxolane moiety.Phototransformation pavhu kana mumhepo haina kukosha kune propiconazole shanduko.Propiconazole inoratidzika kuva nepakati kusvika pasi pekufamba muvhu.Iyo ine mukana wekusvika pasi pemvura kuburikidza neleaching, kunyanya muvhu rine yakaderera organic matter.Propiconazole inowanzoonekwa muvhu repamusoro, asi zvigadzirwa zvekushandura zvakaonekwa zvakadzika muvhu.
