Flumioxazin yog cov tshuaj tua kab mob uas tau nqus los ntawm cov nplooj ntoo lossis cov noob qoob loo uas tsim cov tsos mob ntawm wilting, necrosis thiab chlorosis hauv 24 teev ntawm daim ntawv thov.Nws tswj txhua xyoo thiab biennial broadleaf nroj thiab nyom;Hauv kev tshawb fawb hauv cheeb tsam hauv Asmeskas, flumioxazin tau pom los tswj 40 hom kab mob dav dav xws li ua ntej lossis tom qab tshwm sim.Cov khoom lag luam muaj cov haujlwm seem nyob ntev txog 100 hnub nyob ntawm cov xwm txheej.

Flumioxazin ua los ntawm inhibition ntawm protoporphyrinogen oxidase, ib qho enzyme tseem ceeb hauv kev sib txuas ntawm chlorophyll.Nws tau pom zoo tias porphyrins khaws cia hauv cov nroj tsuag raug mob, ua rau photosensitization uas ua rau daim nyias nyias lipid peroxidation.Lub peroxidation ntawm daim nyias nyias lipids ua rau irreversible kev puas tsuaj ntawm daim nyias nyias muaj nuj nqi thiab cov qauv hauv cov nroj tsuag raug.Kev ua haujlwm ntawm flumioxazin yog lub teeb thiab nyob ntawm oxygen.Kev kho cov av nrog flumioxazin yuav ua rau cov nroj tsuag raug tsim tawm kom tig necrotic thiab tuag sai tom qab raug tshav ntuj.

Flumioxazin tuaj yeem siv los ua kev kho mob kub hnyiab hauv kev txo qis tillage cultivation systems ua ke nrog glyphosate lossis lwm yam khoom tom qab tshwm sim nrog rau Valent's Select (clethodim).Nws tuaj yeem siv ua ntej cog mus txog qhov tshwm sim ntawm cov qoob loo tab sis yuav ua rau muaj kev puas tsuaj loj rau cov taum pauv yog tias siv tom qab kev tshwm sim ntawm cov qoob loo.Cov khoom yog xaiv tau zoo rau cov taum pauv thiab txiv laum huab xeeb thaum thov ua ntej tshwm sim.Hauv kev sim cov noob taum, flumioxazin muab kev sib npaug lossis kev tswj zoo dua li metribuzin tab sis ntawm cov ntawv thov qis heev.Flumioxazin tuaj yeem ua tank tov nrog clethodim, glyphosate, thiab paraquat rau burndown daim ntawv thov ntawm txiv laum huab xeeb, thiab tuaj yeem ua tank tov nrog dimethenamid, ethalfuralin, metolachlor, thiab pendimethalin rau kev siv ua ntej ntawm cov txiv laum huab xeeb.Rau kev siv ntawm cov taum pauv, flumioxazin tuaj yeem ua tank tov nrog clethodim, glyphosate, imazaquin, thiab paraquat rau kev siv hluav taws kub, thiab nrog clomazone, cloransulam-methyl, imazaquin, imazethapyr, linuron, metribuzin, pendimethalin rau kev siv ua ntej.

Hauv cov vaj txiv hmab, flumioxazin feem ntau yog siv rau kev ua ntej ntawm cov nroj tsuag.Rau daim ntawv thov tom qab tshwm sim, sib tov nrog foliar herbicides raug pom zoo.Cov khoom no tsuas yog pom zoo siv rau cov vines uas muaj tsawg kawg yog plaub xyoos.
