Movement of 2,6‐dichlorobenzonitrile in Soils and in Plants in Relation to Its Physical Properties

Summary. The movement of the herbicide H133 (2,6‐dichlorobenzonitrile) in soils and in plants is shown to be governed mainly by its relatively high volatility, its low solubility in water and its strong adsorption on lignin, on humic matter and on lipid material. Some evidence for a transformation of H133 in plants is presented. Les déplacemcnts du 2,6‐dichlorobenzonitrile dans les sols et dans les plantes et leurs relations avec les proriétés physiques
