Flumioxazin kukhudzana ndi herbicide poletsa udzu
Mafotokozedwe Akatundu
Flumioxazin ndi mankhwala opha tizilombo omwe amatengedwa ndi masamba kapena mbande zomwe zikumera zomwe zimatulutsa zizindikiro za kufota, necrosis ndi chlorosis mkati mwa maola 24 atayikidwa.Imawongolera udzu ndi udzu wapachaka komanso zaka ziwiri;m’mafukufuku a m’chigawo cha ku America, flumioxazin inapezeka kuti imalamulira mitundu 40 ya udzu umene unamera usanamera kapena ukamera.Chogulitsacho chimakhala ndi zochitika zotsalira mpaka masiku 100 kutengera momwe zinthu ziliri.
Flumioxazin imagwira ntchito poletsa protoporphyrinogen oxidase, puloteni yofunikira pakuphatikizika kwa chlorophyll.Akuti ma porphyrins amadziunjikira m'zomera zomwe zitha kutengeka, zomwe zimapangitsa photosensitization yomwe imatsogolera ku membrane lipid peroxidation.The peroxidation wa lipids nembanemba kumabweretsa kuwonongeka kosasinthika kwa ntchito ya nembanemba ndi kapangidwe kake muzomera zomwe zimakhudzidwa.Zochita za flumioxazin ndizopepuka komanso zimadalira mpweya.Kuchiza dothi ndi flumioxazin kumapangitsa kuti mbewu zomwe zangophuka kumene zisinthe kukhala necrotic ndikufa patangopita dzuwa.
Flumioxazin ikhoza kugwiritsidwa ntchito ngati mankhwala oyaka moto m'makina ocheperako olima minda kuphatikiza glyphosate kapena zinthu zina zomwe zamera kuphatikiza Valent's Select (clethodim).Itha kuikidwa mbeu isanabzalidwe mpaka ikamera koma imawononga kwambiri soya ikagwiritsidwa ntchito mbeu ikamera.Mankhwalawa amasankha kwambiri soya ndi chiponde akagwiritsidwa ntchito zisanachitike.M'mayesero am'munda wa soya, flumioxazin idapereka kuwongolera kofanana kapena bwinoko kuposa metribuzin koma pamitengo yotsika kwambiri.Flumioxazin ikhoza kukhala thanki yosakanikirana ndi clethodim, glyphosate, ndi paraquat kuti igwiritsidwe ntchito pa mtedza, ndipo ikhoza kukhala thanki yosakanikirana ndi dimethenamid, ethalfuralin, metolachlor, ndi pendimethalin kuti iyambe kugwiritsidwa ntchito pa mtedza.Kuti mugwiritse ntchito pa soya, flumioxazin imatha kukhala thanki yosakanikirana ndi clethodim, glyphosate, imazaquin, ndi paraquat pakuwotcha, komanso ndi clomazone, cloransulam-methyl, imazaquin, imazethapyr, linuron, metribuzin, pendimethalin pakugwiritsa ntchito zisanachitike.
M'minda ya mpesa, flumioxazin imagwiritsidwa ntchito kwambiri kuti udzu uyambe kumera.Pazogwiritsa ntchito zitamera, kusakaniza ndi mankhwala ophera udzu kumalimbikitsidwa.Mankhwalawa amangolimbikitsidwa kuti agwiritsidwe ntchito pamipesa yomwe ili ndi zaka zosachepera zinayi.
