I-Difenoconazole triazole i-broad-spectrum fungicide yokuvikela izitshalo

Incazelo yomkhiqizo

I-Difenoconazole uhlobo lwesikhunta sohlobo lwe-triazole.Kuwumuthi wokubulala isikhunta onemisebenzi ehlukahlukene, evikela isivuno kanye nekhwalithi ngokufaka amahlamvu noma ngokwelashwa kwembewu.Kuthatha ukusebenza ngokusebenza njenge-inhibitor ye-sterol 14α-demethylase, ivimbela i-biosynthesis ye-sterol.Ngokuvimbela inqubo ye-sterol biosynthesis, ivimbela ukukhula kwe-mycelia nokuhluma kwamagciwane ngezinhlamvu, ekugcineni icindezele ukwanda kwesikhunta.I-Difenoconazole isetshenziswe kakhulu ezinhlobonhlobo zezitshalo emazweni amaningi ngenxa yekhono layo lokulawula izifo ezihlukahlukene zesikhunta.Futhi ingenye yezibulala-zinambuzane ezibaluleke kakhulu nezisetshenziswa kakhulu ekulawuleni izifo erayisini.Ihlinzeka ngemisebenzi ehlala isikhathi eside futhi yokwelapha ngokumelene ne-Ascomycetes, i-Basidiomycetes kanye ne-Deuteromycetes.Isetshenziswa ngokumelene nezinkinga zezifo kumagilebhisi, izithelo zepome, izithelo zamatshe, amazambane, isithombo sebhitrudi, ukudlwengula kwembewu, ubhanana, imihlobiso kanye nezitshalo zemifino ehlukahlukene.Ibuye isetshenziselwe ukwelashwa kwembewu ngokumelene nohlu lwamagciwane akolweni nebhali.Kukolweni, ukufakwa kwamaqabunga okuqala ezigabeni zokukhula ezingama-29-42 kungase kubangele, ezimweni ezithile, ukubonakala kwamahlamvu ane-chlorotic, kodwa lokhu akunawo umthelela esivunoni.

Kunolwazi olulinganiselwe olushicilelwe mayelana nemetabolism ye-difenoconazole.Ihlakazwa kancane kancane enhlabathini, futhi i-metabolism ezitshalweni ihilela ukugqashuka kokuxhumanisa kwe-triazole noma i-oxidation yeringi ye-phenyl elandelwa ukuhlangana.

Isiphetho Sezemvelo:
Izilwane: ngemva kokuphathwa ngomlomo, i-difenoconazole yakhishwa ngokushesha iphelele, ngomchamo kanye nendle.Izinsalela ezicutshini zazingabalulekile futhi abukho ubufakazi bokunqwabelana.Nakuba kungenzeka ukuthi i-molecule ehambayo mancane amathuba okuthi ingene ngenxa yokuncibilika kwayo okumanzi okuphansi.Nokho inamandla okuthutha eboshwe yizinhlayiyana.Iyaguquguquka kancane, iyaphikelela enhlabathini nasendaweni ehlala emanzini.Kunokukhathazeka okuthile mayelana namandla ayo e-bioaccumulation.Inobuthi obuphakathi kwabantu, izilwane ezincelisayo, izinyoni kanye nezinto eziningi eziphilayo zasemanzini.
