Tribenuron methyl yog sulfonylurea herbicide nrog cov yam ntxwv hauv qab no thiab siv:
1. Cov ntaub ntawv dav dav
Tribenuron methyl yog sulfonylurea herbicide.
Nws hom kev ua yog inhibition ntawm acetolactate synthase (pab pawg 2 ntawm Pawg Neeg Saib Xyuas Kev Ua Phem Txhaum Cai ntawm Kev faib tawm).
Cov hauv qab no yog cov chaw siv ntawm cov khoom:
2. Siv cov qoob loo
Daim ntawv thov tom qab tshwm sim nyob rau hauv barley, canola, paj rwb, flax, oats, sunflowers, nplej, thiab nyom zus rau cov noob rau kev xaiv tswj ntawm broadleaf weeds.
Xaiv cov tshuaj tua kab mob tom qab tshwm sim rau kev tswj cov nroj tsuag dav dav hauv cov qoob loo cereal (nplej, barley, rye, triticale, thiab oats). Absorbed thiab kis los ntawm stems thiab nplooj ntawm cov nroj tsuag los tiv thaiv cell division thiab ua rau cov nroj tsuag tuag. Qhov zoo tshaj plaws siv rau thaum ntxov caij nplooj ntoos hlav thaum cov nroj tsuag nquag loj hlob.
Tribenuron methyl yog siv los tswj txhua xyoo thiab perennial dicots hauv cereals thiab av av. Siv raws li ib tug foliar tshuaj tsuag thiab ncaj qha mus rau cov av, sai absorbed los ntawm foliage thiab cov hauv paus hniav thiab translocated thoob plaws hauv cov nroj tsuag mus rau loj hlob cov ntsiab lus. Inhibits lub synthesis ntawm amino acids (valine thiab isoleucine), tiv thaiv cell faib thiab loj hlob. Kev xaiv tshwm sim vim qhov sib txawv ntawm sulfonylurea metabolism ntawm cov qoob loo thiab cov nroj tsuag. Cov nroj tsuag raug mob rau kev kho mob xws li thistle, dock, curl sorrel, yarrow, mis thistle, plantain, dandelion, horsetail, buttercup, thiab coltsfoot. Cov qoob loo tsim nyog rau kev kho mob muaj xws li barley, durum nplej, ntsuab npog ntawm cov av av, oats, rye (lub caij ntuj no), triticale, thiab nplej.
Ib qho tshuaj tua kab mob tseem ceeb rau kev tswj cov nroj tsuag broadleaf hauv cov nplej, muaj txiaj ntsig tiv thaiv ntau yam paj ntoo txhua xyoo xws li flixweed (Descurainia sophia), tus tswv yug yaj lub hnab (Capsella bursa-pastoris), thiab toothwort (Dentaria maxima). Tsis muaj txiaj ntsig tiv thaiv cov nroj tsuag xws li cov tsiaj qus oats (Avena fatua), tiaj tiaj nyom nyom foxtail (Alopecurus aequalis), thiab Japanese brome (Bromus japonicus).
Cov hauv qab no yog cov chaw siv ntawm cov khoom:
3. Cov qauv tsim thiab kev sib xyaw ua ke
Tribenuron methyl tuaj yeem siv los ua 50% lossis 75% cov qauv, xws li dej dispersible granules.
Tribenuron methyl tuaj yeem siv ua ke nrog thiensulfuron-methyl tshwj xeeb rau barley thiab nplej.
4. Lwm yam kev siv
Tribenuron methyl kuj tseem siv tau rau hauv qee cov qoob loo lossis thaj chaw uas xav tau kev tswj cov nroj tsuag broadleaf, tab sis daim ntawv thov nyob rau hauv cov cheeb tsam no kuj yuav raug txwv piv rau nws siv hauv cov nplej teb.
