Solubility In water 33 mg/l (pH 7, 22 °C). In ethyl acetate 24, acetone 31, dichloromethane 28, ethanol 15, toluene 4.0, n-hexane 0.11, n-octanol 8.7 (all in g/l, 25 °C).
Stability Relatively stable in neutral, weakly acidic and weakly alkaline media. Rapidly hydrolysed to the hydroxy derivative in strong acids and alkalis, and at 70 °C in neutral media; DT50 (pH 1) 9.5, (pH 5) 86, (pH 13) 5.0 d.
Mode of Action
Selective systemic herbicide, absorbed principally through the roots, but also through the foliage, with translocation acropetally in the xylem and accumulation in the apical meristems and leaves.
