Ionic Herbicides
This profile can be used for food, vegetation, soil or water samples.
Included in this profile are the common chlorophenoxy acid herbicides. The half-life in soil of most of
these compounds is relatively short, on the order of 30 days or less. A few of
them, especially triclopyr and picloram, can survive in soil much longer. Most are commonly
sold as water soluble salts, which are ionic in nature. Ester forms, which are
generally oil (or emulsion) based, will hydrolyze rapidly under field conditions to the free
acid form which is ionic. We report results for these herbicides as the free
acid equivalent.
