Bixlozone yog ib qho kev xaiv dav dav uas siv tshuaj tua kab mob uas yog siv rau hauv qab zib, rape, nplej, paj rwb, soybean thiab lwm yam qoob loo los tswj cov nroj tsuag txhua xyoo. Cov khoom no tau siv dav txij li thaum nws tso tawm, thiab Brazil tuav txog 1/3 ntawm kev ua lag luam; Tsis yog cov qoob loo, qab zib, thiab rapeseed yog nws qhov chaw tseem ceeb tshaj plaws.

Mechanism ntawm kev ua thiab kev siv
Bixlozone yog ib qho deoxy-D-xyluose phosphate synthase (DEOXY-D-XYLULOSE PHOSPHATE SYNTHASE; DOXP lossis DXS luv luv) inhibitor. Classified as Group F4 (los yog HRAC/WSSA Group 13) los ntawm International Herbicide Resistance Action Committee (HRAC). Tam sim no, tsuas muaj 2 cov khoom xyaw nquag hauv pawg no, bixlozone thiab clomazone.
Bixlozone cuam tshuam plastid isoprenoid biosynthesis thiab blocks carotenoid synthesis los ntawm inhibiting deoxy-D-xylulose phosphate synthase (DOXP). Yog li ntawd, cov nroj tsuag raug mob tsis tuaj yeem ua photosynthesis ib txwm, thiab cov nroj tsuag tig dawb, daj, lossis poob ntsuab, tsis loj hlob, thiab tuag.
Deoxy-D-xylulose phosphate synthase yog thawj tus nqi txwv enzyme ntawm mevalonate (MEP) txoj hauv kev thiab qhov tseem ceeb ntawm kev tswj hwm enzyme ntawm txoj kev. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj hwm ntawm monoterpene thiab diterpene aroma compounds, carotenoids, chlorophyll thiab lwm yam tseem ceeb.
Bixlozone feem ntau yog absorbed los ntawm cov hauv paus hniav thiab seedlings ntawm cov nroj tsuag, thiab yog ua los ntawm cov hauv paus hniav los ntawm transpiration. Nws yog thauj mus rau ntau qhov chaw ntawm cov nroj tsuag los ntawm xylem (tsis ua downward los yog ntawm nplooj), cuam tshuam cov nroj tsuag photosynthesis thiab ua rau cov nroj tsuag rhiab heev tuag nyob rau hauv ib lub sij hawm luv luv.
Bixlozone yog ib qho dav-spectrum xaiv tshuaj tua kab mob nrog rau cov kab mob thiab kev sib cuag. Feem ntau siv nyob rau hauv cov qoob loo xws li txiv hmab txiv ntoo, zaub, mov, cereals (xws li barley, nplej, sorghum, rye, thiab lwm yam), pob kws, legumes, paj rwb, qab zib beet, rapeseed, qab zib, thiab lwm yam. Tswj broadleaf weeds, nyom. weeds, sedges, thiab lwm yam, thiab muaj txiaj ntsig zoo tiv thaiv cov nyom nyuaj xws li ryegrass. Nws muaj lub sijhawm ntev daim ntawv thov lub qhov rais thiab zoo persistence. Nws tuaj yeem siv rau lub sijhawm sowing lossis ua ntej lossis tom qab tshwm sim. Nws tsis tsuas yog muaj kev tswj xyuas zoo ntawm cov nroj tsuag uas twb tau tshwm sim lawm, tab sis kuj muaj qee yam kev tswj xyuas cov nroj tsuag uas tshwm sim tom qab, thiab cov nyhuv kav ntev txog 12 lub lis piam. Nws tuaj yeem siv rau kev tswj hwm kev tiv thaiv thiab zoo tiv thaiv qee cov nroj tsuag uas tiv taus. Tsis tas li ntawd, Bixlozone cov khoom tam sim no tsuas yog cov tshuaj tua kab mob uas tuaj yeem siv rau hauv peb lub caij ntuj no qoob loo loj, suav nrog cov nplej, barley, thiab rapeseed, muab kev yooj yim dua rau cov qoob loo tig.
