Metabolism of [(14)C]Flamprop-isopropyl in suspension cultures from Medicago sativa and Phaseolus sp.

Metabolism of the selective herbicide flamprop-isopropyl (isopropyl-N-benzoyl-N-(3-chloro-4-fluorophenyl)-2-aminopropionate) in suspension cultures of the dicotyledons Phaseolus vulgaris, P. multiflorus and Medicago sativa showed general similarities be, but particular variations from, that reported in intact plants of Hordeum vulgare. Hydrolysis of the ester and conjugation were major routes, but some hydroxylation and hydrolysis of the amide was also observed. The implications of these variations are discussed.
