I-Flumioxazin idibane ne-herbicide yokutshatyalaliswa kokhula lwamagqabi abanzi

Ingcaciso yeMveliso

I-Flumioxazin sisichiza esibulala ukhula esifunxwa ngamagqabi okanye izithole ezintshulayo sivelisa iimpawu zokubuna, necrosis kunye nechlorosis kwiiyure ezingama-24 zokufakwa.Ilawula ukhula kunye nengca yamagqabi abanzi ngonyaka kunye naminyaka emibini;kwizifundo zengingqi eMelika, i-flumioxazin yafunyaniswa ilawula ama-40 eentlobo zokhula zamagqabi abanzi mhlawumbi ngaphambi okanye emva kokuhluma.Imveliso inomsebenzi oshiyekileyo ukuya kwiintsuku ze-100 ngokuxhomekeke kwiimeko.

I-Flumioxazin isebenza ngokunqanda i-protoporphyrinogen oxidase, i-enzyme ebalulekileyo kwi-synthesis ye-chlorophyll.Kucetyiswa ukuba i-porphyrins iqokelele kwizityalo ezithintekayo, ezibangela i-photosensitization ekhokelela kwi-membrane lipid peroxidation.I-peroxidation ye-membrane lipids ikhokelela kumonakalo ongenakuguqulwa womsebenzi we-membrane kunye nesakhiwo kwizityalo ezithintekayo.Umsebenzi we-flumioxazin ulula kwaye uxhomekeke kwi-oxygen.Ukunyangwa komhlaba nge-flumioxazin kuya kubangela ukuba izityalo ezihlumayo zijike zibe necrotic kwaye zife kamsinya emva kokuchanabeka elangeni.

I-Flumioxazin ingasetyenziswa njengonyango lokutshisa kwiinkqubo zokulima ezicuthiweyo zokulima ngokudibanisa ne-glyphosate okanye ezinye iimveliso eziphuma emva kokuhluma kuquka iValent's Select (clethodim).Ingagalelwa phambi kokutyala kude kuvele isityalo kodwa iya kubangela umonakalo omkhulu kwimbotyi yesoya ukuba igalelwe emva kokuhluma kwesityalo.Imveliso ikhetha kakhulu kwimbotyi yesoya kunye ne-peanut xa isetyenziswe kwangaphambili.Kulingo lwentsimi yeembotyi zesoya, i-flumioxazin inike ulawulo olulinganayo okanye olungcono kune-metribuzin kodwa kumazinga asezantsi kakhulu esicelo.I-Flumioxazin ingaba itanki exutywe ne-clethodim, i-glyphosate, kunye ne-paraquat yokusetyenziswa kwe-burndown kwi-peanuts, kwaye ingaba itanki exutywe ne-dimethenamid, i-ethalfuralin, i-metolachlor, kunye ne-pendimethalin yokusetyenziswa kwangaphambili kwi-peanuts.Ukusetyenziswa kwiimbotyi zesoya, i-flumioxazin ingaba itanki exutywe ne-clethodim, i-glyphosate, i-imazaquin, kunye ne-paraquat yokusetyenziswa kwe-burndown, kunye ne-clomazone, i-cloransulam-methyl, i-imazaquin, i-imazethapyr, i-linuron, i-metribuzin, i-pendimethalin yokusetyenziswa kwangaphambili.

Kwizidiliya, iflumioxazin yeyokuqala ukuntshula kokhula.Ukusetyenziswa emva kokuhluma, imixube kunye nemichiza yokutshabalalisa ukhula kucetyiswa.Imveliso iyacetyiswa ukuba isetyenziswe kwimidiliya eneminyaka emine ubuncinci.
