Propiconazole systemic jakejado ohun elo triazole fungicide
Apejuwe ọja
Propiconazole jẹ iru ti triazole fungicide, o ti lo ni ọpọlọpọ awọn ohun elo.A nlo lori awọn koriko ti a gbin fun irugbin, olu, agbado, iresi igbẹ, ẹpa, almondi, oka, oats, pecans, apricots, peaches, nectarines, plums ati prunes.Lori awọn woro irugbin o nṣakoso awọn arun ti o ṣẹlẹ nipasẹ Erysiphe graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides, Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, ati Septoria spp.
Ipo iṣe Propiconazole jẹ demethylation ti C-14 lakoko biosynthesis ergosterol (nipasẹ idinamọ iṣẹ ti 14a-demethylase gẹgẹbi alaye ni isalẹ), ati eyiti o yori si ikojọpọ ti C-14 methyl sterols.Biosynthesis ti awọn ergosterols wọnyi jẹ pataki si dida awọn odi sẹẹli ti elu.Aini iṣelọpọ sterol deede yii fa fifalẹ tabi da idagba ti fungus duro, ni idinamọ ni imunadoko siwaju ikolu ati/tabi ayabo ti awọn tissu ogun.Nitorinaa, propiconazole ni a gba pe o jẹ fungistatic tabi idilọwọ idagbasoke kuku ju fungicidal tabi pipa.
Propiconazole tun jẹ oludena agbara ti Brassinosteroids biosynthesis.Brassinosteroids (BRs) jẹ awọn homonu sitẹriọdu sitẹriọdu poly-hydroxylated pẹlu awọn ipa ti o jinle lori ọpọlọpọ awọn idahun ọgbin ti ẹkọ iṣe-ara.Wọn ṣe alabapin ninu ṣiṣe iṣakoso elongation sẹẹli ati pipin, iyatọ ti iṣan, photomorphogenesis, itọsi igun ewe, germination irugbin, idagbasoke stomata, bakanna bi titẹkuro ti abọ ewe ati abscission.
Propiconazole (PCZ) wa laarin awọn julọ ti a lo ninu iṣẹ-ogbin.Awọn fungicides Triazole ni igbesi aye idaji kukuru ati kekere bioaccumulation ju awọn ipakokoropaeku organochlorine, ṣugbọn awọn ipa ipakokoro lori ilolupo inu omi le dide lati fiseete sokiri tabi ṣiṣiṣẹ dada lẹhin ojo.Wọn ti royin lati ṣe iyipada si awọn metabolites keji ni awọn osin ori ilẹ.
Propiconazole wọ inu ayika ilẹ ni iṣẹ rẹ bi fungicide fun ọpọlọpọ awọn irugbin.Ni agbegbe ti ilẹ, propiconazole ti wa ni gbekalẹ lati jẹ die-die jubẹẹlo si itẹramọṣẹ.Biotransformation jẹ ipa ọna pataki ti iyipada fun propiconazole, pẹlu awọn ọja iyipada pataki jẹ 1,2,4-triazole ati awọn agbo ogun hydroxylated ni dioxolane moiety.Phototransformation lori ile tabi ni afẹfẹ ko ṣe pataki fun iyipada propiconazole.Propiconazole han lati ni alabọde si kekere arinbo ni ile.O ni agbara lati de omi ilẹ nipasẹ fifẹ, paapaa ni awọn ile pẹlu akoonu ọrọ Organic kekere.Propiconazole jẹ igbagbogbo ti a rii ni awọn ipele ile oke, ṣugbọn awọn ọja iyipada ni a rii jinle ni profaili ile.
