Pali mitundu iwiri ya fungicides yomwe imagwiritsidwa ntchito posamalira udzu ndi kuwongolera matenda,PropiconazolendiAzoxystrobin, iliyonse ili ndi maubwino apadera komanso mawonekedwe ogwiritsira ntchito. Monga awothandizira fungicide, tikuwonetsa kusiyana pakati paPropiconazole ndi Azoxystrobinkudzera mu njira yochitira, ntchito zazikulu ndi zabwino za fungicides ziwirizi.
Kodi Propiconazole ndi chiyani?
Propiconazole ndi triazole fungicide yokhala ndi mankhwala a C15H17Cl2N3O2. Njira yake yochitira ndikuletsa kaphatikizidwe ka ergosterol mu cell nembanemba ya bowa, motero kupewa kukula ndi kubereka kwa maselo a mafangasi.
Njira yochitira
Propiconazole ndi systemic fungicide, yomwe imatha kutengeka ndi masamba ndi mizu ya zomera ndikuyendetsedwa m'thupi kuti muteteze ndi kuchiza matenda. Imalepheretsa kwambiri biosynthesis ya bowa ergosterol, imawononga kukhulupirika ndi ntchito ya fungal cell membrane, ndipo pamapeto pake imatsogolera kufa kwa ma cell a mafangasi.
Ntchito zazikulu
Propiconazole chimagwiritsidwa ntchito ulimi, horticulture ndi kusamalira udzu, makamaka kulamulira zosiyanasiyana matenda a mafangasi, kuphatikizapo:
Matenda a udzu: mawanga a bulauni, dzimbiri, choipitsa, zowola, etc.
Matenda a mitengo yazipatso: matenda a apulosi akuda, dzimbiri la mapeyala, zowola za pichesi, etc.
Matenda a masamba: powdery mildew, downy mildew, imvi nkhungu ndi zina zotero.
Matenda a mbewu yambewu: dzimbiri la tirigu, kuphulika kwa mpunga, matenda a corn gray spot, etc.
Ubwino waukulu
Broad-spectrum: Propiconazole ndi yothandiza polimbana ndi matenda osiyanasiyana a mafangasi, kuphatikiza mawanga a bulauni, dzimbiri, powdery mildew, etc.
Utali wautali wa moyo: Imakhala ndi nthawi yayitali ndipo imatha kupereka kuwongolera matenda mosalekeza.
Kulowa mwamphamvu: Imatha kulowa mwachangu m'magulu a zomera kuti ipewe ndikuchiza matenda omwe angakhalepo.
Kugwiritsa ntchito
Propiconazole nthawi zambiri amagwiritsidwa ntchito ngati kupopera pamwamba pa udzu, kangapo pachaka, koma chisamaliro chiyenera kutengedwa kuti tipewe kugwiritsa ntchito mosalekeza kuti tipewe kukula kwa fungal kukana.
Kodi Azoxystrobin ndi chiyani?
Azoxystrobin ndi methoxyacrylate fungicide ndi mankhwala formula C22H17N3O5. Njira yake yayikulu ndikulepheretsa kupuma kwa mitochondrial chain complex III (cytochrome bc1 complex) ya bowa, kutsekereza kusamutsa mphamvu kwa cell ya mafangasi ndikupangitsa kufa kwa fungal cell.
Njira yochitira
Azoxystrobin ndi systemic fungicide yomwe imatha kuyamwa kudzera m'masamba, mapesi, ndi mizu, ndipo imathandizira muzomera. Conductivity iyi imathandiza kuteteza masamba omwe akutuluka ndi mbali zina za zomera zomwe sizigwirizana mwachindunji ndi wothandizira, ndipo zimakhala zothandiza kwambiri popewa komanso kuchiza matenda a fungal.
Kugwiritsa Ntchito Kwambiri
Azoxystrobin amagwiritsidwa ntchito kwambiri muulimi ndi ulimi wamaluwa, makamaka mu kapinga, mitengo ya zipatso, masamba ndi mbewu za chakudya. Zolinga zake zazikulu zowongolera ndi izi:
Matenda a udzu: mawanga a bulauni, dzimbiri, zowola, zowola, etc.
Matenda a mitengo yazipatso: matenda a black star, moldy mildew, anthracnose, etc.
Matenda a masamba: imvi nkhungu, downy mildew, powdery mildew, etc.
Matenda a mbewu yambewu: dzimbiri la tirigu, kuphulika kwa mpunga, mawanga a bulauni a soya, etc.
Ubwino waukulu
Kuchita bwino kwambiri: Azoxystrobin imakhala ndi mabakiteriya othamanga komanso amphamvu pamitundu yambiri ya bowa.
Broad-spectrum: Amatha kuthana ndi matenda osiyanasiyana a panthambi monga mawanga a bulauni, dzimbiri ndi zowola.
Kutetezedwa kwakukulu: Kuchepa kwa kawopsedwe ku chilengedwe komanso zamoyo zomwe sizingawathandize, zomwe zimapangitsa kuti zikhale zotetezeka kugwiritsa ntchito.
Kugwiritsa ntchito
Azoxystrobin angagwiritsidwe ntchito popopera mbewu mankhwalawa kapena kuthirira mizu. Kuchuluka kwa ntchito nthawi zambiri kumachitika kamodzi pa milungu iwiri iliyonse, koma nthawi yeniyeni yogwiritsira ntchito iyenera kusinthidwa malinga ndi momwe matenda a udzu alili.
Propiconazole VS Azoxystrobin
Kuyerekeza zotsatira
Kulimbikira: Propiconazole imakhala ndi nthawi yayitali yolimbikira, koma Azoxystrobin imagwira ntchito mwachangu.
Broad-spectrum: Zonsezi zimakhala ndi fungicidal effect, koma zotsatira zake zimatha kusiyana pa matenda osiyanasiyana.
Kuwongolera kukana: Kusinthana kwa Propiconazole ndi Azoxystrobin kumatha kuchedwetsa kukula kwa matenda oyamba ndi fungus.
Kuyerekeza Kwachuma
Mtengo: Propiconazole nthawi zambiri imakhala yotsika mtengo, koma Azoxystrobin ikhoza kukhala yokwera mtengo pang'ono chifukwa cha mphamvu zake komanso chitetezo.
Kutsika mtengo: Kutengera matenda enieni komanso zosowa za udzu, kusankha mankhwala oyenera opha bowa kumatha kukhala kotsika mtengo kwambiri.
Malangizo ndi chenjezo loti mugwiritse ntchito
Kusinthasintha Koyenera
Pofuna kupewa kukula kwa matenda oyamba ndi fungus, tikulimbikitsidwa kugwiritsa ntchito Propiconazole ndi Azoxystrobin. Izi sizingowonjezera kuwongolera, komanso kukulitsa moyo wautumiki wa fungicide.
Chitetezo cha chilengedwe
Mukamagwiritsa ntchito fungicides, chisamaliro chiyenera kuperekedwa pakuteteza chilengedwe. Pewani kugwiritsa ntchito mopitirira muyeso, zomwe zingasokoneze chilengedwe cha kapinga. Nthawi yomweyo, kugwiritsa ntchito bwino kwa fungicides kuyenera kutsatiridwa kuwonetsetsa kuti alibe vuto kwa anthu ndi nyama.
Zochita zenizeni
Njira zogwiritsira ntchito Propiconazole
Kukonzekera: Sakanizani Propiconazole ndi madzi molingana ndi malangizo.
Utsi wogawana: Utsi wofanana pamwamba pa kapinga ndi sprayer.
Kalekale: Pambuyo pa kupopera kulikonse, bwerezaninso pakadutsa milungu 3-4.
Njira Yogwiritsira Ntchito Azoxystrobin
Kukonzekera: Sakanizani Azoxystrobin ndi madzi molingana ndi malangizo.
Kupopera mbewu mankhwalawa kapena kuthirira mizu: Mutha kugwiritsa ntchito popopera mbewu mankhwalawa kapena kuthirira mizu.
Kuwongolera pafupipafupi: Mukamaliza kugwiritsa ntchito kulikonse, bwerezaninso pakadutsa milungu 2-3.
Mwachidule
Propiconazole ndi Azoxystrobin pakuwongolera matenda a udzu pakusintha koyenera kwa kugwiritsa ntchito ma fungicides awiriwa, sikungowonjezera mphamvu ya kuwongolera, komanso kuchedwetsa kufalikira kwa matenda oyamba ndi fungus, kuti azindikire kukula kwa thanzi kwanthawi yayitali. udzu.
