Propiconazole ts'ebeliso e pharaletseng ea triazole fungicide
Tlhaloso ea Sehlahisoa
Propiconazole ke mofuta oa triazole fungicide, e sebelisoa haholo lits'ebetsong tse fapaneng.E sebelisoa ka joang bo lengoang bakeng sa peo, li-mushroom, poone, raese ea naha, matokomane, lialmonde, mabele, oats, pecans, apricots, liperekisi, nectarines, plums le prunes.Ho lijo-thollo e laola mafu a bakoang ke Erysiphe graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides, Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, le Septoria spp.
Mokhoa oa ts'ebetso oa Propiconazole ke demethylation ea C-14 nakong ea ergosterol biosynthesis (ka ho thibela ts'ebetso ea 14a-demethylase joalo ka ha ho hlalositsoe ka tlase), mme e lebisa ho bokelleng ha C-14 methyl sterols.The biosynthesis ea li-ergosterol tsena e bohlokoa ho thehoeng ha marako a lisele tsa li-fungus.Khaello ena ea tlhahiso e tloaelehileng ea sterol e liehisa kapa e emisa kholo ea fungus, e thibela ka katleho tšoaetso e eketsehileng le/kapa tlhaselo ea lisele tse amohelang.Ka hona, propiconazole e nkoa e le fungistatic kapa kholo e thibelang ho e-na le fungicidal kapa ho bolaea.
Propiconazole hape ke inhibitor e matla ea Brassinosteroids biosynthesis.Brassinosteroids (BRs) ke lihomone tsa poly-hydroxylated steroidal tse nang le litlamorao tse tebileng likarabelong tse 'maloa tsa semela sa 'mele.Ba kenya letsoho ho laola karohano ea lisele le karohano, phapang ea methapo ea mali, photomorphogenesis, tšekamelo ea mahlakoreng a makhasi, ho mela ha peo, nts'etsopele ea stomata, hammoho le ho thibela ho ruruha ha makhasi le ho senyeha ha makhasi.
Propiconazole (PCZ) ke e 'ngoe ea tse sebelisoang haholo temong.Likokoana-hloko tsa Triazole li na le halofo ea bophelo e khuts'oane le bioaccumulation e tlase ho feta chefo e bolaeang likokonyana ea organochlorine, empa litlamorao tse kotsi tikolohong ea metsing li ka hlaha ka lebaka la ho hoholeha ha sefaha kapa ho thella holim'a metsi ka mor'a pula.Li tlalehoa hore li fetoha li-metabolite tsa bobeli ho liphoofolo tse anyesang tsa lefatše.
Propiconazole e phunyeletsa tikolohong ea lefatše mosebetsing oa eona e le sebolaea-khuru bakeng sa mefuta e fapaneng ea lijalo.Sebakeng sa lefats'e, propiconazole e hlahisoa e le e phehellang hanyane ho phehella.Biotransformation ke tsela ea bohlokoa ea phetoho bakeng sa propiconazole, ka lihlahisoa tse kholo tsa phetoho e le 1,2,4-triazole le metsoako ea hydroxylated karolong ea dioxolane.Phototransformation mobung kapa moeeng ha e bohlokoa bakeng sa phetoho ea propiconazole.Propiconazole e bonahala e na le motsamao o mahareng ho isa tlase mobung.E na le monyetla oa ho fihlela metsi a fatše ka ho leaching, haholo-holo mobung o nang le lintho tse fokolang tsa tlhaho.Propiconazole hangata e fumanwa dikarolong tse ka hodimo tsa mobu, empa dihlahiswa tsa phetoho di ile tsa fumanwa botebong ba boemo ba mobu.
