(1) Cov qoob loo tsim nyog thiab kev nyab xeeb nplej. Kev nyab xeeb rau cov nplej yog raws li nws cov degradation sai hauv cov nplej cog. Tab sis nws yog teeb meem rau barley thiab oats.
(2) Cov hom phiaj tswj yog cov nyom nyom txhua xyoo thiab txhua xyoo thiab qee cov nroj tsuag dav dav, xws li oats qus, bluegrass, Polygonum, Rhizoma chinensis, thiab lwm yam.
(3) Yuav siv li cas Nws yog tsuas yog siv rau cov nroj tsuag tom qab tshwm sim hauv cov nplej. Qhov koob tshuaj yog 10-35g (ai/hm2[mu dosage yog 0.67-2.34 g (ai)].
(g·hm2 yog qhov ntau npaum li cas rau ib hectar, thiab hectar yog lub metric unit (ntiaj teb unit) ntawm cheeb tsam.
[biochemical] branched-chain amino acid synthesis (ALS lossis AHAS) inhibitors. Tiv thaiv cell faib thiab cog kev loj hlob los ntawm inhibiting biosynthesis ntawm qhov tseem ceeb amino acids valine thiab isoleucine. Herbicidal selectivity nyob ntawm cov metabolism hauv cov qoob loo sai.
Cov kev xaiv metabolic hauv paus ntawm sulfonylureas raug tshuaj xyuas hauv: MK Koeppe, HM Brown, Agro-Food-Industry, 1995, 6:9-14. [Action hom] Cov tshuaj tua kab mob, nqus los ntawm cov hauv paus hniav thiab / lossis nplooj, thiab xa mus rau symplast thiab apoplast.

Nws tau raug pov thawj tias nws tuaj yeem tswj tau txhua xyoo cov nroj tsuag dav dav thiab cov nroj tsuag gramineous hauv cov nplej (nplej) teb, thiab qhov ntau npaum li cas yog 10-35g/hm2. Nws kuj tseem siv tau rau kev cog qoob loo hauv thaj av uas tsis muaj qoob loo.
Sensitive rau barley thiab oats, tshwj xeeb kam rau ua rau durum nplej. Tsis sib haum nrog cov tshuaj chiv nrog pH tsawg dua los yog sib npaug li 5, los yog tsis muaj ionic surfactants los yog lwm yam additives uas yuav ua rau cov pH ntawm cov tshuaj tsuag tsuag yuav tsum tsawg tshaj li 5. Incompatible nrog malathion.
60 hnub tom qab cog qoob loo, yog tias organophosphorus insecticides tau siv rau kev kho mob furrow, yog tias cov khoom no siv, nws yooj yim ua rau phytotoxicity.
