I-Tribenuron-methyl ikhemikhali enefomula yemolekyuli ye-C15H17N5O6S.Okokukhipha ukhula.I-mechanical iyi-systemic conduction type herbicide ekhethiwe, engamuncwa izimpande namaqabunga okhula futhi yenziwe ezitshalweni.Ngokuvimbela umsebenzi we-acetolactate synthase (ALS), ithinta i-biosynthesis yama-amino acid e-branched-chain (njenge-leucine, isoleucine, i-valine, njll.).

Amafomu omthamo ojwayelekile

I-10% i-Tribenuron-methyl WP, i-75% ye-Tribenuron-methyl amanzi ahlakazekayo ama-granules (owaziwa nangokuthi ukumiswa okomile noma ukumiswa okomile).

Into yokuvimbela

Isetshenziselwa kakhulu ukulawula ukhula oluhlukahlukene lonyaka olunamaqabunga abanzi.Inemiphumela engcono ku-Artemisia annua, Isikhwama Somalusi, Isikhwama Somalusi Elayisi Esiphukile, i-Maijiagong, i-Quinoa, i-Amaranthus, njll. Iphinde ibe nomthelela othile wokulawula.Ayinawo umthelela obalulekile kuthistle yasensimini, i-polygonum cuspidatum, i-field bindweed, ne-lacquer, futhi ayisebenzi ekulweni nokhula olufana ne-wild oat, i-kangaroo, i-brome, ne-jiejie.

Indlela yokwenza

Lo mkhiqizo uyi-systemic and conductive herbicide ekhethiwe, engamuncwa izimpande namaqabunga okhula futhi iqhutshwe ezitshalweni.Ngokuvimbela umsebenzi we-acetolactate synthase (ALS), ithinta i-biosynthesis yama-amino acid e-branched-chain (njenge-leucine, isoleucine, i-valine, njll.).Ngemuva kokulimala kwesitshalo, indawo yokukhula iba yi-necrotic, imithambo yeqabunga i-chlorotic, ukukhula kwesitshalo kuvinjelwa kakhulu, kunciphile, futhi ekugcineni sonke isitshalo siyabuna.Ukhula oluzwelayo luyayeka ukukhula ngokushesha ngemva kokumunca i-ejenti futhi luyafa ngemva kwamaviki angu-1-3.

Iziyalezo

Kusukela esigabeni samaqabunga ama-2 kuya esigabeni sokuhlangana kukakolweni, ukhula lusetshenziswa ngaphambi noma ekuqaleni kwesithombo.Umthamo ojwayelekile ka-10% we-Trisulfuron WP ngu-10-20g/mu, kanti inani lamanzi liyi-15-30kg, kanti iziqu zokhula namaqabunga afuthwa ngokulinganayo.Lapho ukhula luncane, umthamo ophansi ungafinyelela umphumela ongcono wokulawula, futhi lapho ukhula lukhulu, sebenzisa umthamo omkhulu.

Izinyathelo zokuzivikela

1. Lo mkhiqizo ungasetshenziswa kanye kuphela ngesizini.

2 .Lo mkhiqizo unomsebenzi ophezulu, futhi umthamo kufanele ulawulwe ngokuqinile ngesikhathi sokuphatha, futhi ukunakekelwa kufanele kukhokhwe ekuxubeni namanzi ngokulinganayo.

3. Lo mkhiqizo ungasetshenziswa kuphela ukulawula ukhula olumilayo, futhi awunamandla okulawula ukhula olungakambiwa.

4. Esimeni sezulu esinomoya, ukufafaza kanye nokufakwa kufanele kumiswe ukuze kuvinjelwe ukukhukhuleka koketshezi ekubangeleni ubuthi be-phytotoxicity kuya ezitshalweni ezinamaqabunga abanzi.

5. Isikhathi esisele salo mkhiqizo emhlabathini cishe izinsuku ezingama-60.

6. Amantongomane namazambane (gwema i-chlorine) ayazwela kulo mkhiqizo.Emasimini kakolweni ebusika lapho kusetshenziswe khona lo mkhiqizo, amakinati akufanele atshalwe kulezi zibindi ezilandelayo.
