 Title    Metabolism of the Herbicide Bromoxynil in Hordeum vulgare and Stellaria media  
 Abstract    The metabolism of [3,5-14C]3,5-dibromo-4-hydroxybenzonitrile (bromoxynil) was studied in Hordeum vulgare and Stellaria media. In excised barley seedlings the time course of metabolism was followed over 48 h and the distribution of radioactivity to various metabolic fractions measured. The metabolites, sepa­ rated by TLC and HPLC, were identified by chemical and spectrometric methods. Bromo-hydroquinone and 2,6-dibromohydroquinone were found, indicating partly debromination and replacement of the nitrile group by hydroxyl. The major parts of bromoxynil and of the metabolites were recovered in glucosidic conjugates. In Stellaria media the same metabolites as in Hordeum vulgare were determined. Additional­ ly, metabolites of unknown structures without bromine were detected.
