Dispersion et transformation de l'isoproturon dans le sol et l'eau

Abstract : ln order to identify processes that act on herbicide isoproturon transfer in soil and water, several experimental studies were attempted. ln the field, isoproturon appeared to reach surface soil water early after treatment. Then, the same soil was used to fill lysimeters placed under natural climatic conditions. Rainwater was able to produce large exportations only during the first month after treatment, because isoproturon, not yet fully degraded, was very mobile. Last, experiments under laboratory controlled conditions showed that isoproturon was sorbed only weakly on soil components. On the opposite, some of its degradation products, which rapidly represent the greatest part of residues, were more strongly held to soil
