I-Flumioxazin ithintana ne-herbicide ukuze ilawule ukhula lwamaqabunga abanzi

Incazelo yomkhiqizo

I-Flumioxazin iwumuthi othintana naye wokubulala ukhula umuncwa amahlamvu noma izithombo ezimilayo eziveza izimpawu zokubuna, i-necrosis kanye ne-chlorosis emahoreni angama-24 okufakwa kwawo.Ilawula ukhula kanye notshani lwamaqabunga abanzi aminyaka yonke kanye notshani;ezifundweni zesifunda eMelika, i-flumioxazin yatholakala ilawula izinhlobo zokhula lwamaqabunga angama-40 ngaphambi noma ngemva kokuhluma.Umkhiqizo unomsebenzi oyinsalela othatha izinsuku ezingafika kweziyi-100 kuye ngezimo.

I-Flumioxazin isebenza ngokuvimbela i-protoporphyrinogen oxidase, i-enzyme ebalulekile ekuhlanganiseni kwe-chlorophyll.Kuphakanyiswa ukuthi ama-porphyrins anqwabelane ezitshalweni ezithintekayo, okubangela i-photosensitization eholela kulwelwesi lwe-lipid peroxidation.I-peroxidation ye-membrane lipids iholela ekulimaleni okungenakuguqulwa kokusebenza kolwelwesi kanye nesakhiwo ezitshalweni ezisengozini.Umsebenzi we-flumioxazin ulula futhi uncike kumoya-mpilo.Ukwelashwa kwenhlabathi nge-flumioxazin kuzodala ukuthi izitshalo ezisakhula zibe necrotic futhi zife ngemuva nje kokuchayeka elangeni.

I-Flumioxazin ingasetshenziswa njengendlela yokwelapha yokushiswa ezinhlelweni zokulinywa kwe-tillage encishisiwe ngokuhlangana ne-glyphosate noma eminye imikhiqizo yangemva kokuhluma okuhlanganisa ne-Valent's Select (clethodim).Ingasetshenziswa ngaphambi kokutshala kuze kube yilapho isilimo simila kodwa izodala umonakalo omkhulu kubhontshisi wesoya uma isetshenziswa ngemva kokuhluma kwesilimo.Umkhiqizo ukhetha kakhulu kubhontshisi wesoya kanye nekinati uma usetshenziswa ngaphambi kokuhluma.Ezivivinyweni zensimu kabhontshisi wesoya, i-flumioxazin inikeze ukulawula okulinganayo noma okungcono kune-metribuzin kodwa ngamanani okusebenza aphansi kakhulu.I-Flumioxazin ingaba ithangi elixutshwe ne-clethodim, i-glyphosate, kanye ne-paraquat ukuze isetshenziswe ekushiseni kumakinati, futhi ingaba ithangi elixutshwe ne-dimethenamid, i-ethalfuralin, i-metolachlor, ne-pendimethalin ukuze isetshenziswe ngaphambi kokuvela kumakinati.Ukuze isetshenziswe kubhontshisi wesoya, i-flumioxazin ingaba ithangi elixutshwe ne-clethodim, i-glyphosate, i-imazaquin, ne-paraquat yokusetshenziswa kokusha, kanye ne-clomazone, i-cloransulam-methyl, i-imazaquin, i-imazethapyr, i-linuron, i-metribuzin, i-pendimethalin yezinhlelo zokusebenza zangaphambi kokuvela.

Ezivinini, i-flumioxazin isetshenziswa ikakhulukazi ngaphambi kokuvela kokhula.Ezitshalweni zangemva kokuhluma, kunconyelwa ukuxutshwa nama-foliar herbicides.Umkhiqizo unconywa kuphela ukuthi usetshenziswe emivinini okungenani eneminyaka emine ubudala.
