I-propiconazole uhlelo olubanzi lwe-triazole fungicide

Incazelo yomkhiqizo

I-Propiconazole iwuhlobo lwe-triazole fungicide, isetshenziswa kakhulu ekusetshenzisweni okuhlukahlukene.Isetshenziselwa utshani obutshalwe imbewu, amakhowe, ummbila, irayisi lasendle, amakinati, ama-alimondi, amabele, ama-oats, ama-pecans, amabhilikosi, amapentshisi, ama-nectarine, ama-plums kanye nama-prunes.Emasimini ilawula izifo ezibangelwa i-Erysiphe graminis, i-Leptosphaeria nodorum, i-Pseudocerosporella herpotrichoides, i-Puccinia spp., i-Pyrenophora teres, i-Rhynchosporium secalis, ne-Septoria spp.

Indlela yokusebenza ye-Propiconazole i-demethylation ye-C-14 ngesikhathi se-ergosterol biosynthesis (ngokuvimbela umsebenzi we-14a-demethylase njengoba kuchazwe ngezansi), futhi okuholela ekuqongeleleni kwe-C-14 methyl sterols.I-biosynthesis yalawa ma-ergosterol ibalulekile ekwakhekeni kwezindonga zamaseli esikhunta.Lokhu kuntuleka kokukhiqizwa kwe-sterol evamile kunciphisa noma kumisa ukukhula kwesikhunta, kuvimbela ngempumelelo ukutheleleka okwengeziwe kanye/noma ukuhlasela kwezicubu eziphethe.Ngakho-ke, i-propiconazole ibhekwa njenge-fungistatic noma inhibiting ukukhula kune-fungicidal noma ukubulala.

I-Propiconazole nayo iyi-inhibitor enamandla ye-Brassinosteroids biosynthesis.I-Brassinosteroids (BRs) amahomoni e-poly-hydroxylated steroidal anemiphumela ejulile ekuphenduleni kwezitshalo ezithile zomzimba.Bahileleke ekulawuleni ukunwetshwa nokuhlukaniswa kwamangqamuzana, ukuhlukaniswa kwemithambo, i-photomorphogenesis, ukuthambekela kwe-leaf angle, ukuhluma kwembewu, ukukhula kwe-stomata, kanye nokucindezelwa kokubonakala kweqabunga kanye ne-abscission.

I-Propiconazole (PCZ) iphakathi kwezisetshenziswa kakhulu kwezolimo.Imithi yokubulala isikhunta i-Triazole inohafu wempilo emfushane futhi i-bioaccumulation ephansi kunezibulala-zinambuzane ze-organochlorine, kodwa imiphumela elimazayo ku-ecosystem yasemanzini ingase ivele ngenxa yokukhukhuleka kwesifutho noma ukugeleza kwamanzi ngemva kokuna kwemvula.Zibikwe ukuthi zishintshe zibe ama-metabolites esibili ezilwaneni ezincelisayo zasemhlabeni.

I-Propiconazole ingena endaweni yasemhlabeni emsebenzini wayo njengesibulala-sikhunta ezitshalweni ezihlukahlukene.Emvelweni wasemhlabeni, i-propiconazole yethulwa njengokuphikelela kancane kokuphikelela.I-Biotransformation iwumzila obalulekile wenguquko ye-propiconazole, enemikhiqizo emikhulu yokuguqula i-1,2,4-triazole kanye nezinhlanganisela ze-hydroxylated ku-dioxolane moiety.I-Phototransformation enhlabathini noma emoyeni ayibalulekile ekuguqulweni kwe-propiconazole.I-Propiconazole ibonakala inokuhamba okuphakathi nokuphansi emhlabathini.Inamandla okufinyelela emanzini angaphansi ngokuvuza, ikakhulukazi enhlabathini enokuqukethwe okuphansi kwezinto eziphilayo.I-Propiconazole ivamise ukutholakala ezingqimbeni zenhlabathi engaphezulu, kodwa imikhiqizo yoguquko yatholwa ekujuleni kwephrofayili yenhlabathi.
