Abstract Diclofop-methyl is diluted in acetonitrile-2% acetic acid (70 + 30) and chromatographed on a reverse phase C-18 column. The anaìyte is eluted by an acetonitrile- 2% acetic acid mobile phase and detected at 280 nm. The method was validated by testing precision, linearity, and recovery. Precision and linearity were excellent (% RSD = 0.55, r2 = 0.9997). A multiple standard addition to a pool of formulation samples showed the method to have excellent recovery (99%) and to be free of matrix interferences
