I-Herbicide Esetshenziselwa Ukulawula Utshani I-Bispyribac-sodium
I-Bispyribac-sodiumisetshenziselwa ukulawula utshani, amasedge kanye nokhula olunamaqabunga abanzi, ikakhulukazi i-Echinochloa spp., erayisini elinembewu eqondile, ngamanani angu-15-45 g/ha. Yayisetshenziselwa futhi ukunqanda ukukhula kokhula ezimweni ezingalinywanga.Isibulala-zinambuzane. I-Bispyribac-sodiumiwumuthi wokubulala ukhula obanzi olawula utshani baminyaka yonke nobuhlala njalo, ukhula olunamaqabunga abanzi kanye nezinsalela. Inefasitela elibanzi lesicelo futhi ingasetshenziswa kusukela ezigabeni zamaqabunga angu-1-7 we-Echinochloa spp; isikhathi esinconywayo yisigaba samaqabunga ama-3-4. Umkhiqizo owokufaka isicelo se-foliar. Ukukhukhula kwensimu ye-paddy kunconywa phakathi kwezinsuku ezingu-1-3 zokufaka isicelo. Ngemuva kokufakwa, ukhula luthatha cishe amasonto amabili ukufa. Izitshalo zibonisa i-chlorosis kanye nokuyeka ukukhula ezinsukwini ezi-3 kuya kwezi-5 ngemuva kokufakwa. Lokhu kulandelwa i-necrosis yezicubu ezibulalayo.
Ukusetshenziswa
Isetshenziselwa ukulawula ukhula lotshani kanye nokhula olunamaqabunga abanzi njengotshani be-barnyard emasimini erayisi, futhi ingasetshenziswa emasimini ezithombo, amasimu okuhlwanyela ngokuqondile, amasimu amancane okutshala izithombo, kanye namasimu okuphonsa izithombo.
