AbstractAbstract: The metabolism of tralkoxydim was studied in wheat grown under field conditions and treated at a rate equivalent to 345 g a.i. ha −1. Maize plant cell suspension culture was used as a means of indicating the nature of the primary metabolic process, and also as a source of material for structural elucidation. The principal metabolic process in wheat involved hydroxylation of thep‐methyl function of the aromatic ring. This occurred in conjunction with a range of possible transformations of the (ethoxyimino)propyl function, or oxidative cleavage of the cyclohexanedione ring. All the initial metabolic products were amenable to further conjugation with a range of endogenous sug
