Propiconazole inkqubo ebanzi isicelo triazole fungicide

Ingcaciso yeMveliso

Ipropiconazole luhlobo lwe-triazole fungicide, isetyenziswa kakhulu kwiintlobo ezahlukeneyo zokusetyenziswa.Isetyenziswa kwingca ekhuliselwa imbewu, amakhowa, umbona, irayisi yasendle, amandongomane, iialmondi, amazimba, ihabile, iipecans, iiapilkosi, iipesika, iinectarines, iiplums kunye neprunes.Kwiinkozo ilawula izifo ezibangelwa yiErysiphe graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides, Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, kunye neSeptoria spp.

Indlela yokusebenza yePropiconazole yi-demethylation ye-C-14 ngexesha le-ergosterol biosynthesis (ngokuthintela umsebenzi we-14a-demethylase njengoko kuchazwe ngezantsi), kwaye kukhokelela ekuqokeleleni kwe-C-14 methyl sterols.I-biosynthesis yezi ergosterols ibaluleke kakhulu ekwakhiweni kweendonga zeeseli zomngundo.Oku kunqongophala kwemveliso ye-sterol eqhelekileyo kuyacotha okanye kunqande ukukhula kwefungus, kuthintela ngokufanelekileyo ukosuleleka ngakumbi kunye / okanye ukuhlasela kwezicubu ezibambayo.Ngoko ke, ipropiconazole ithathwa njenge-fungistatic okanye inhibiting ukukhula kunokuba i-fungicidal okanye ukubulala.

I-Propiconazole nayo i-inhibitor enamandla ye-Brassinosteroids biosynthesis.I-Brassinosteroids (BRs) ziihomoni ze-poly-hydroxylated steroidal ezineziphumo ezinzulu kwiimpendulo ezininzi zezityalo ze-physiological.Babandakanyeka ekulawuleni ukwanda kweeseli kunye nokwahlula, ukwahlula kwe-vascular, i-photomorphogenesis, i-leaf angle inclination, ukuhluma kwembewu, ukuphuhliswa kwe-stomata, kunye nokunyanzeliswa kwe-leaf senescence kunye ne-abscission.

IPropiconazole (PCZ) iphakathi kwezona zisetyenziswa kakhulu kwezolimo.Imichiza yokungunda ye-Triazole inobomi obufutshane obufutshane kunye ne-bioaccumulation esezantsi kune-organochlorine yezitshabalalisi, kodwa iziphumo eziyingozi kwi-ikhosistim yasemanzini zinokuvela ngenxa yokukhukhuleka kokutshiza okanye ukubaleka komhlaba emva kokuna kwemvula.Ziye zaxelwa ukuba zitshintshe kwi-metabolites yesibini kwizilwanyana ezincancisayo ezisemhlabeni.

IPropiconazole igqobhoza imo engqongileyo esemhlabeni ekusebenzeni kwayo njengesibulala-ntsholongwane sokungunda kwiintlobo ngeentlobo zezityalo.Kwimeko-bume yomhlaba, ipropiconazole iboniswa ukuba izingise kancinci ukuzingisa.I-Biotransformation yindlela ebalulekileyo yokuguqulwa kwepropiconazole, kunye neemveliso ezinkulu zokuguqulwa zibe yi-1,2,4-triazole kunye neekhompawundi ze-hydroxylated kwi-dioxolane moiety.I-Phototransformation emhlabeni okanye emoyeni ayibalulekanga kwinguqu yepropiconazole.Ipropiconazole ibonakala inokuhamba okuphakathi ukuya kokuphantsi emhlabeni.Inamandla okufikelela kumanzi aphantsi komhlaba ngokuvuza, ngakumbi kwimihlaba enezinto eziphilayo eziphantsi.Ipropiconazole idla ngokubhaqwa kumaleko omhlaba aphezulu, kodwa iimveliso zoguqulo zichongiwe nzulu kwinkangeleko yomhlaba.
