IHerbicide esetyenziselwa ukulawula iGrasses Bispyribac-sodium
Bispyribac-sodiumisetyenziselwa ukulawula ingca, iisedges kunye nokhula olunamagqabi abanzi, ngakumbi i-Echinochloa spp., kwirayisi enembewu ethe ngqo, kumlinganiselo we-15-45 g/ha.Ikwasetyenziselwa ukunqanda ukukhula kokhula kwiimeko ezingalinywanga.Imichiza yokutshabalalisa ukhula.I-Bispyribac-sodium sisichiza sokutshabalalisa ukhula esibanzi esilawula ingca yonyaka kunye nengapheli, ukhula olunamagqabi abanzi kunye namasedge.Inefestile ebanzi yesicelo kwaye ingasetyenziswa ukusuka kwinqanaba le-1-7 leqabunga le-Echinochloa spp;ixesha elicetyiswayo linqanaba le-3-4 lamagqabi.Imveliso yeyesicelo samagqabi.Ukukhukhula kwentsimi ye-paddy kucetyiswa phakathi kweentsuku ze-1-3 zokufaka isicelo.Emva kokufakwa, ukhula luthatha malunga neeveki ezimbini ukufa.Izityalo zibonisa i-chlorosis kunye nokuyeka ukukhula kwiintsuku ezi-3 ukuya kwezi-5 emva kokufakwa.Oku kulandelwa yi-necrosis ye-terminal tissues.
Ukusetyenziswa
Isetyenziselwa ukulawula ukhula lwengca kunye nokhula olunamagqabi abanzi njenge barnyard grass kumasimi erayisi, kwaye ingasetyenziswa kumasimi ezithole, amasimi embewu ngokuthe ngqo, amasimi amancinci okutyalwa kwezithole, kunye namasimi okulahla izithole.
