A herbicidal formulation comprising of incorporating the herbicide in a micelle or vesicle and adsorbing said micelle or vesicle containing herbicide on clay mineral. The formulation is suitable in particular for negatively charged herbicides at pH above 6. The herbicidal formulation provides slow release and reduced leaching of the herbicide to deep soil layers, thus reducing contamination of underground water and soil. Furthermore, the herbicide is maintained in the target vicinity, thus its efficiency is enhanced and a smaller concentration may be used.
L'invention concerne une formulation d'herbicide préparée par incorporation de l'herbicide dans une micelle ou un vésicule et par adsorption de cette micelle ou de ce vésicule sur un minéral argileux. Cette formulation convient en particulier aux herbicides chargés négativement à un pH supérieur à 6. La formulation d'herbicide permet une libération lente et un lessivage réduit de l'herbicide dans les couches profondes du sol, ce qui diminue la contamination de l'eau souterraine et du sous-sol. En outre, l'herbicide est maintenu au voisinage de la cible, ce qui augmente son efficacité et permet de l'utiliser à des concentrations plus faibles.
