Tsuas muaj ib lo lus txawv ntawm glyphosate thiab glufosinate-ammonium.Txawm li cas los xij, ntau tus tswv lag luam tawm tswv yim thiab cov phooj ywg ua liaj ua teb tseem tsis paub meej txog ob "cov kwv tij" no thiab tsis tuaj yeem paub qhov txawv ntawm lawv zoo.Yog li dab tsi yog qhov txawv?Glyphosate thiab glufosinate sib txawv heev!Leej twg tua cov nroj tsuag zoo dua?

1. Mechanism ntawm kev ua:Glyphosate blocks protein synthesis thiab kis mus rau hauv av los ntawm stems thiab nplooj.Nws muaj zog ua kom puas tsuaj rau cov ntaub so ntswg hauv av ntawm cov nroj tsuag sib sib zog nqus thiab tuaj yeem ncav cuag qhov tob uas cov tshuab ua liaj ua teb tsis tuaj yeem ncav cuag.Glufosinate yog ammonium tiv tauj tua uas inhibits glutamine synthesis, ua rau nitrogen metabolism hauv cov nroj tsuag.Ib tug loj npaum li cas ntawm ammonium accumulates nyob rau hauv cov nroj tsuag thiab chloroplasts disintegrate, yog li inhibiting nroj tsuag photosynthesis thiab nws thiaj li ua rau cov nroj tsuag tuag.

2. Systemicity: Glyphosate yog qhov systemic thiab conductive, thaum glufosinate yog semi-systemic lossis tsis muaj zog thiab tsis ua haujlwm.

3. Lub sijhawm tua cov nroj tsuag:Txij li lub hauv paus ntsiab lus ntawm kev txiav txim ntawm glyphosate yog tua cov hauv paus hniav los ntawm kev nqus dej, nws feem ntau siv sijhawm li 7-10 hnub, thaum glyphosate yuav siv sij hawm 3-5 hnub tom qab siv.

4. Weeding Scope:Glyphosate muaj peev xwm tswj tau ntau dua 160 hom nroj tsuag, suav nrog monocotyledonous thiab dicotyledonous, txhua xyoo thiab perennial, tshuaj ntsuab thiab nroj tsuag.Txawm li cas los xij, nws cov kev tswj xyuas ntawm qee cov nroj tsuag muaj hnub nyoog malignant tsis zoo tagnrho.Cov nyhuv ntawm glyphosate tsis pom tseeb rau cov kab mob malignant xws li goosegrass, knotweed, thiab flyweed;glufosinate yog ib qho dav-spectrum, tiv tauj-tua, biocidal, non-residual herbicide nrog ntau yam kev siv.Glufosinate tuaj yeem siv rau yuav luag tag nrho cov qoob loo (nws tsuas yog tsis tuaj yeem txau rau ntawm qhov ntsuab ntawm cov qoob loo).Nws tuaj yeem siv rau kev tswj cov nroj tsuag ntawm kab ntawm cov ntoo txiv ntoo thiab zaub cog rau hauv kab dav thiab hauv thaj av uas tsis muaj av;tshwj xeeb tshaj yog rau cov nroj tsuag glyphosate-tolerant.Qee cov nroj tsuag tsis zoo, xws li cowweed, purslane, thiab dwarf weeds, zoo heev.

5. Kev nyab xeeb:Glyphosate yog tshuaj tua kab mob biocidal uas cuam tshuam rau cov hauv paus qoob loo thiab tsis tuaj yeem siv rau hauv cov hauv paus hauv paus cag.Nws tseem nyob hauv av thiab metabolizes ntev.Glufosinate yuav luag tsis muaj kev nqus thiab kev ua haujlwm hauv cov hauv paus hniav.Nws tuaj yeem metabolized hauv av hauv 3-4 hnub.Cov av ib nrab-lub neej yog tsawg dua 10 hnub.Nws muaj kev cuam tshuam tsawg heev rau cov av, cov hauv paus hniav thiab cov qoob loo tom ntej.
