Propiconazole systemic hoʻohana ākea triazole fungicide
wehewehe huahana
ʻO Propiconazole kahi ʻano o ka triazole fungicide, hoʻohana nui ʻia i nā ʻano hana like ʻole.Hoʻohana ʻia ia ma nā mauʻu i ulu ʻia no ka hua, nā halo, ka kulina, ka laiki hihiu, ka pīkī, nā ʻalemona, sorghum, oats, pecans, apricots, peaches, nectarines, plums and prunes.Ma ka cereals e hoʻomalu i nā maʻi i hoʻokumu ʻia e Erysiphe graminis, Leptosphaeria nodorum, Pseudocerosporella herpotrichoides, Puccinia spp., Pyrenophora teres, Rhynchosporium secalis, a me Septoria spp.
ʻO ke ʻano o ka hana a Propiconazole ka demethylation o C-14 i ka wā ergosterol biosynthesis (ma ke kāohi ʻana i ka hana o 14a-demethylase e like me ka kikoʻī ma lalo nei), a ke alakaʻi nei i ka hōʻiliʻili ʻana o C-14 methyl sterols.He mea koʻikoʻi ka biosynthesis o kēia mau ergosterols i ka hoʻokumu ʻana i nā paia cell o nā haʻi.ʻO kēia nele o ka hana sterol maʻamau e hoʻolohi a hoʻōki i ka ulu ʻana o ka haʻo, e pale pono i ka maʻi hou a/a i ka hoʻouka ʻana i nā ʻiʻo hoʻokipa.No laila, ua manaʻo ʻia ʻo propiconazole he fungistatic a i ʻole ka ulu ʻana ma mua o ka fungicidal a pepehi paha.
ʻO ka Propiconazole kekahi mea paʻa ikaika o ka biosynthesis Brassinosteroids.ʻO nā Brassinosteroids (BRs) he poly-hydroxylated steroidal hormones me nā hopena koʻikoʻi ma nā pane o nā mea kanu physiological.Hoʻopili lākou i ka hoʻoponopono ʻana i ka elongation cell a me ka hoʻokaʻawale ʻana, ka ʻokoʻa vascular, photomorphogenesis, inclination angle lau, germination seed, stomata development, a me ka hoʻopau ʻana i ka senescence o ka lau a me ka abscission.
ʻO Propiconazole (PCZ) kekahi o nā mea i hoʻohana nui ʻia i ka mahiʻai.ʻOi aku ka pōkole o ka hapalua o ke ola a me ka haʻahaʻa o ka bioaccumulation ma mua o nā pesticides organochlorine, akā hiki ke hopena i nā hopena pōʻino i ke kaiaola wai mai ka hoʻoheheʻe ʻana a i ʻole ka holo ʻana o ka ʻili ma hope o ka ua.Ua hōʻike ʻia lākou e hoʻololi i nā metabolites lua i nā mammals terrestrial.
Hoʻokomo ka Propiconazole i ka honua honua i kāna hana ma ke ʻano he fungicide no nā ʻano mea kanu.Ma ka honua honua, ua hōʻike ʻia ka propiconazole e hoʻomau iki i ka hoʻomau.ʻO ka biotransformation kahi ala nui o ka hoʻololi ʻana no propiconazole, me nā huahana hoʻololi nui ʻo 1,2,4-triazole a me nā pūhui hydroxylated ma ka moiety dioxolane.ʻAʻole koʻikoʻi ka phototransformation ma ka lepo a i ka ea no ka hoʻololi propiconazole.ʻIke ʻia he haʻahaʻa ka neʻe ʻana o ka Propiconazole i ka lepo.Hiki iā ia ke komo i ka wai o ka lepo ma o ka leaching, ʻoi aku ka maikaʻi ma nā lepo me ka haʻahaʻa o nā mea organik.ʻIke pinepine ʻia ka Propiconazole ma nā papa lepo o luna, akā ʻike ʻia nā huahana hoʻololi i ka hohonu o ka ʻike lepo.
