I-Azoxystrobin systemic fungicide yokunakekelwa kwezitshalo nokuvikela
Ulwazi Oluyisisekelo
I-Azoxystrobin iyi-systemic fungicide, esebenzayo ngokumelene ne-Ascomycetes, i-Basidiomycetes, i-Deuteromycetes ne-Oomycetes.Inokuvimbela, ukwelapha kanye ne-translaminar kanye nomsebenzi oyinsalela othatha amasonto ayisishiyagalombili kuma-cereal.Umkhiqizo ukhombisa ukumunca kwamaqabunga okunensa, okuqinile futhi unyakaza kuphela ku-xylem.I-Azoxystrobin ivimbela ukukhula kwe-mycelial futhi inomsebenzi we-anti-sporulant.Isebenza kahle kakhulu ezigabeni zokuqala zokukhula kwesikhunta (ikakhulukazi ekuhlumeni kwembewu) ngenxa yokuvimbela ukukhiqizwa kwamandla.Umkhiqizo uhlukaniswa njengesibulala-sikhunta seQembu K.I-Azoxystrobin iyingxenye yekilasi lamakhemikhali aziwa ngokuthi ama-ß-methoxyacrylates, atholakala ezinhlanganisela ezenzeka ngokwemvelo futhi asetshenziswa kakhulu ezindaweni zezolimo.Ngalesi sikhathi, i-Azoxystrobin ukuphela kwesikhunta esinamandla okunikeza isivikelo ezinhlotsheni ezine ezinkulu zesikhunta sezitshalo.
I-Azoxystrobin yatholwa okokuqala phakathi kocwaningo olwenziwa ngamakhowe esikhunta avame ukutholakala emahlathini aseYurophu.Lamakhowe amancane abathakazelisa ososayensi ngenxa yekhono lawo eliqinile lokuzivikela.Kwatholakala ukuthi indlela yokuzivikela yamakhowe yayisekelwe ekukhiqizweni kwezinto ezimbili, i-strobilurin A kanye ne-oudemansin A. Lezi zinto zanikeza isikhunta ikhono lokuvimbela izimbangi zabo futhi zibabulale lapho zisebangeni.Ukubhekwa kwalo mshini kwaholela ocwaningweni olwaholela ekusungulweni kwesikhunta se-Azoxystrobin.I-Azoxystrobin isetshenziswa kakhulu ezindaweni zokulima kanye nokusetshenziswa kwezentengiso.Kunemikhiqizo equkethe i-Azoxystrobin ekhawulelwe ukusetshenziswa noma enganconyelwe ukusetshenziswa endaweni yokuhlala ngakho uzodinga ukuhlola ukulebula ukuze uqiniseke.
I-Azoxystrobin inokunyibilika okune-aqueous okuphansi, ayiguquguquki futhi ingase igeleze emanzini angaphansi komhlaba ngaphansi kwezimo ezithile.Ingase iphikelele enhlabathini futhi ingaba nesineke ezinhlelweni zamanzi uma izimo zilungile.Inobuthi obuncane bezilwane ezincelisayo kodwa ingase iqongelele.Kuyacasula isikhumba namehlo.Inobuthi obusesilinganisweni ezinyonini, ezintweni eziningi eziphila emanzini, ezinyosini nasezibungwini.
