Tribenuron-methyl yog ib qho tshuaj lom neeg nrog cov mis molecular ntawm C15H17N5O6S.Rau weeding.Lub mechanism yog ib tug xaiv systemic conduction hom herbicide, uas yuav absorbed los ntawm cov hauv paus hniav thiab nplooj ntawm cov nroj tsuag thiab ua nyob rau hauv cov nroj tsuag.Los ntawm inhibiting qhov kev ua ntawm acetolactate synthase (ALS), nws cuam tshuam rau biosynthesis ntawm branched-chain amino acids (xws li leucine, isoleucine, valine, thiab lwm yam).

Cov ntawv ntau npaum li cas

10% Tribenuron-methyl WP, 75% Tribenuron-methyl dej dispersible granules (tseem hu ua qhuav suspension lossis qhuav suspension).

Cov khoom tiv thaiv

Nws yog tsuas yog siv rau kev tswj ntawm ntau yam txhua xyoo broad-leaved weeds.Nws muaj cov teebmeem zoo dua ntawm Artemisia annua, Shepherd's Purse, Broken Rice Shepherd's Purse, Maijiagong, Quinoa, Amaranthus, thiab lwm yam. Nws kuj muaj qee yam kev tswj xyuas.Nws tsis muaj qhov cuam tshuam tseem ceeb rau thaj teb thistle, polygonum cuspidatum, teb bindweed, thiab lacquer, thiab tsis muaj txiaj ntsig zoo rau cov nyom nyom xws li oat qus, kangaroo, brome, thiab jiejie.

Mechanism ntawm kev ua

Cov khoom no yog ib qho kev xaiv systemic thiab conductive herbicide, uas tuaj yeem nqus tau los ntawm cov hauv paus hniav thiab nplooj ntawm cov nroj tsuag thiab ua rau cov nroj tsuag.Los ntawm inhibiting qhov kev ua ntawm acetolactate synthase (ALS), nws cuam tshuam rau biosynthesis ntawm branched-chain amino acids (xws li leucine, isoleucine, valine, thiab lwm yam).Tom qab cov nroj tsuag raug mob, qhov kev loj hlob taw tes yog necrotic, nplooj nplooj cov leeg yog chlorotic, cov nroj tsuag loj hlob yog heev inhibited, dwarfed, thiab nws thiaj li tag nrho cov nroj tsuag withers.Cov rhiab heev tsis loj hlob tam sim ntawd tom qab nqus tus neeg sawv cev thiab tuag tom qab 1-3 lub lis piam.

Cov lus qhia

Los ntawm theem 2-nplooj mus rau theem sib koom ntawm cov nplej, cov nroj tsuag tau siv ua ntej lossis ntxov tom qab yub.Kev siv ntau npaum li cas ntawm 10% Trisulfuron WP yog 10-20g / mu, thiab cov dej yog 15-30kg, thiab cov nroj tsuag stems thiab nplooj yog sib npaug zos txau.Thaum cov nroj tsuag me me, koob tshuaj tsawg tuaj yeem ua tiav cov txiaj ntsig zoo dua, thiab thaum cov nroj tsuag loj, siv tshuaj ntau.

Cov kev ceev faj

1. Cov khoom no tsuas yog siv tau ib zaug hauv ib lub caij.

2.Cov khoom no muaj kev ua haujlwm siab, thiab ntau npaum li cas yuav tsum tau tswj nruj me ntsis thaum tswj hwm, thiab kev saib xyuas yuav tsum tau them rau kev sib xyaw nrog dej sib npaug.

3. Cov khoom no tsuas yog siv tau los tswj cov nroj tsuag uas tau tshwm sim, thiab muaj kev tswj tsis zoo rau cov nroj tsuag uas tsis tau khawb.

4. Nyob rau hauv huab cua huab cua, tshuaj tsuag thiab daim ntawv thov yuav tsum tau nres kom tsis txhob ya raws ntawm cov kua los ntawm ua rau phytotoxicity rau cov nyob ib sab broad-leaved qoob loo.

5. Lub sij hawm seem ntawm cov khoom no hauv av yog txog 60 hnub.

6. Cov txiv laum huab xeeb thiab cov qos yaj ywm (tsis txhob muaj cov tshuaj chlorine) rhiab rau cov khoom no.Nyob rau lub caij ntuj no nplej teb uas cov khoom no tau siv, txiv laum huab xeeb yuav tsum tsis txhob cog rau hauv cov hauv qab no stubble.
