Cyhalofop-butyl yog cov tshuaj tua kab mob uas tsim los ntawm Dow AgroSciences, uas tau tsim tawm hauv Asia xyoo 1995. Cyhalofop-butyl muaj kev nyab xeeb siab thiab tswj tau zoo, thiab tau txais kev nyiam los ntawm kev lag luam txij li thaum nws tau pib. Tam sim no, kev ua lag luam ntawm Cyhalofop-butyl kis thoob plaws thaj chaw cog qoob loo hauv ntiaj teb, suav nrog Nyiv, Tuam Tshoj, Tebchaws Meskas, Tim Nkij teb chaws, Spain, Fabkis, Ltalis, Portugal thiab Australia. Hauv kuv lub tebchaws, Cyhalofop-butyl tau dhau los ua tus neeg sawv cev tseem ceeb rau cov nroj tsuag xws li barnyardgrass thiab stephenia hauv cov liaj teb.
Khoom taw qhia
Cyhalofop-butyl cov khoom lag luam yog cov khoom siv dawb crystalline, soluble hauv feem ntau cov kuab tshuaj organic, insoluble hauv dej, nws cov mis molecular yog C20H20FNO4, CAS npe: 122008-85-9
Mechanism ntawm kev ua
Cyhalofop-butyl yog ib hom kab mob tshuaj tua kab mob. Tom qab absorbed los ntawm nplooj thiab nplooj sheaths ntawm cov nroj tsuag, nws ua los ntawm phloem thiab accumulates nyob rau hauv lub meristem cheeb tsam ntawm cov nroj tsuag, qhov uas nws inhibits acetyl-CoA carboxylase (ACCase) thiab synthesizes fatty acids. Nres, cov hlwb tsis tuaj yeem loj hlob thiab sib faib ib txwm, cov txheej txheem membrane thiab lwm yam lipid-muaj cov qauv raug rhuav tshem, thiab thaum kawg cov nroj tsuag tuag.
Tswj khoom
Cyhalofop-butyl yog tsuas yog siv nyob rau hauv lub yub yub, direct seed teb, thiab transplanting teb, thiab muaj peev xwm tswj thiab tswj Qianjinzi, kanmai, me bran nyom, crabgrass, foxtail, bran millet, plawv nplooj millet, pennisetum, pobkws, thiab nqaij nyuj tendon. Nyom thiab lwm cov nroj tsuag gramineous, nws kuj muaj qee yam kev tswj xyuas ntawm cov tub ntxhais hluas barnyardgrass, thiab tseem tuaj yeem tswj cov nroj tsuag uas tiv taus quinclorac, sulfonylurea thiab amide tshuaj tua kab.
Khoom zoo
1. Cov tshuaj tua kab mob siab heev
Cyhalofop-butyl tau nthuav tawm cov tshuaj tua kab mob tsis sib xws los ntawm lwm cov tshuaj tua kab ntawm D. chinensis ua ntej 4-nplooj nplooj hauv teb nplej.
2. Ntau yam kev thov
cyhalofop-butyl tuaj yeem siv tsis tau tsuas yog hauv kev cog qoob loo, tab sis kuj tseem nyob rau hauv kev cog qoob loo ncaj qha thiab cog qoob loo.
3. Muaj zog adaptability
Cyhalofop-butyl tuaj yeem sib xyaw nrog penoxsulam, quinclorac, fenoxaprop-ethyl, oxaziclozone, thiab lwm yam, uas tsis tsuas yog nthuav tawm cov tshuaj tua kab mob, tab sis kuj tseem ncua kev tshwm sim ntawm kev tiv thaiv.
4. Kev ruaj ntseg siab
Cyhalofop-butyl muaj kev xaiv zoo rau cov nplej, muaj kev nyab xeeb rau cov nplej, degrades sai hauv cov av thiab cov dej paddy, thiab muaj kev nyab xeeb rau cov qoob loo tom ntej.
Kev lag luam kev cia siab
Rice yog cov zaub mov tseem ceeb tshaj plaws hauv lub ntiaj teb. Nrog rau kev nthuav dav ntawm thaj chaw ncaj qha-seeding ntawm cov nplej thiab qhov nce ntawm qhov tsis kam ntawm cov nyom nyom, kev ua lag luam thov rau cyhalofop-butyl raws li cov tshuaj tua kab mob zoo thiab nyab xeeb hauv cov nplej yog tas li nce. Tam sim no, thaj chaw tshwm sim thiab kev puas tsuaj ntawm cov nroj tsuag xws li Dwarfiaceae thiab barnyardgrass hauv cov nplej hauv kuv lub tebchaws tau nce zuj zus, thiab kev tiv thaiv rau sulfonylurea thiab amide tshuaj tua kab mob hnyav dua. Nws cia siab tias qhov kev thov rau cyhalofop-butyl tseem yuav nce ntxiv nyob rau ob peb xyoos tom ntej no. Thiab vim yog qhov teeb meem ntawm kev tiv thaiv, ib koob tshuaj cyhalofop-fop yuav zoo li tsim nrog cov ntsiab lus siab (30% -60%), thiab cov khoom sib xyaw nrog lwm cov tshuaj tua kab yuav nce ntxiv. Nyob rau tib lub sijhawm, nrog rau kev nthuav dav ntawm lub Hoobkas qhov ntau lawm thiab kev kho dua tshiab ntawm cov txheej txheem cov cuab yeej, kev ua lag luam muaj peev xwm ntawm cyhalofop-butyl thiab cov khoom uas muaj cyhalofop-butyl yuav nthuav dav ntxiv thiab kev sib tw yuav khaus ntau dua. Tsis tas li ntawd, nrog rau qhov nrov tshaj plaws ntawm kev siv tshuaj tua kab tsuag, cyhalofop-ester yog qhov tsim nyog rau kev siv ntau yam tshuaj tiv thaiv ya, thiab daim ntawv thov kev siv yav tom ntej tseem tsim nyog tos ntsoov rau.
