I-Tribenuron-methyl yinto yekhemikhali ene-molecular formula ye-C15H17N5O6S.Ukuhlakula.Isixhobo sisichiza esikhethiweyo sodidi lwe-conduction uhlobo lokutshabalalisa ukhula, olufunxwa ziingcambu namagqabi okhula kwaye luqhutywe kwizityalo.Ngokuthintela umsebenzi we-acetolactate synthase (ALS), ichaphazela i-biosynthesis ye-branched-chain amino acids (njenge-leucine, isoleucine, i-valine, njl.).

Iifom zedosi eqhelekileyo

I-10% ye-Tribenuron-methyl WP, i-75% ye-Tribenuron-methyl yamanzi ahlambulukileyo (eyaziwa nangokuthi ukumiswa okomileyo okanye ukumisa okomileyo).

Into yothintelo

Ikakhulu isetyenziselwa ukutshabalalisa ukhula olunamagqabi abanzi onyaka.Ineziphumo ezingcono kwi-Artemisia annua, iSipaji sikaMalusi, iSipaji soMalusi eRayisi esaphukileyo, iMaijiagong, iQuinoa, i-Amaranthus, njl.Ayinampembelelo ibonakalayo kwithafa lentsimi, i-polygonum cuspidatum, i-field bindweed, kunye ne-lacquer, kwaye ayisebenzi ngokuchasene nokhula lwengca olufana ne-oat yasendle, i-kangaroo, i-brome, kunye ne-jiejie.

Indlela yokwenza

Le mveliso yi-systemic ekhethiweyo kunye ne-conductive herbicide, enokuthi ifunnwe ziingcambu kunye namagqabi okhula kwaye iqhutywe kwizityalo.Ngokuthintela umsebenzi we-acetolactate synthase (ALS), ichaphazela i-biosynthesis ye-branched-chain amino acids (njenge-leucine, isoleucine, i-valine, njl.).Emva kokuba isityalo sonzakele, indawo yokukhula iba yi-necrotic, imithambo yeqabunga i-chlorotic, ukukhula kwesityalo kuyathintelwa kakhulu, kunciphe, kwaye ekugqibeleni isityalo sonke siyabuna.Ukhula olubuthathaka luyayeka ukukhula ngokukhawuleza emva kokufunxa i-arhente kwaye lufe emva kweeveki ezi-1-3.

Imiyalelo

Ukususela kwinqanaba lamagqabi ama-2 ukuya kwinqanaba lokudityaniswa kwengqolowa, ukhula lugalelwa phambi okanye kwangethuba emva kokuba izithole.Idosi eqhelekileyo ye-10% ye-Trisulfuron WP yi-10-20g/mu, kwaye umthamo wamanzi yi-15-30kg, kunye neziqu zokhula kunye namagqabi afafazwe ngokulinganayo.Xa ukhula luncinci, idosi ephantsi inokufezekisa impembelelo yokulawula engcono, kwaye xa ukhula lukhulu, sebenzisa idosi ephezulu.

Ukulumkela

1. Le mveliso ingasetyenziswa kanye kuphela ngexesha lonyaka.

2 .Le mveliso inomsebenzi ophezulu, kwaye i-dosage kufuneka ilawulwe ngokungqongqo ngexesha lolawulo, kwaye ingqalelo kufuneka ihlawulwe ukuxubana namanzi ngokulinganayo.

3. Le mveliso ingasetyenziselwa kuphela ukulawula ukhula oluthe lwavela, kwaye inefuthe elibi lokulawula ukhula olungakhange luvulwe.

4. Kwimozulu enomoya, ukutshiza kunye nokugalela kufuneka kuyekwe ukuthintela ukukhukuliseka kolwelo ekubangeleni ubutyhefu bezityalo ezikufutshane nezityalo ezinamagqabi abanzi.

5. Ixesha lentsalela yale mveliso emhlabeni limalunga neentsuku ezingama-60.

6. Amantongomane kunye namazambane (ugweme i-chlorine) inovelwano kule mveliso.Ebusika amasimi engqolowa apho le mveliso igalelwe, amandongomane akufuneki atyalwe kwezi zikhondo zilandelayo.
