A phytotron bioassay using oat Avena sativa L.) showed that cyanazine was not present at phytotoxic levels in the top soil samples (0-10 cm depth_ taken from trated plots four weeks after treatment in areas cultivated with soybeans.  acyanazine  aHerbicides  aHerbicida  aBioatividade  aBioensaio  aBioensaios  aTropico umido1 aMATALLO, M.
