Abstract
Cette invention se rapporte à un procédé de stabilisation, vis à vis de la cristallisation du pesticide en présence, de dispersions aqueuses de microcapsules contenant une forte charge de pesticide sous la forme de produits surfondus ou de solutions sursaturées. Ledit procédé consiste à s'assurer que le diamètre volumique moyen des microcapsules reste inférieur à 6 µm, et à utiliser des agents tensioactifs qui ne forment pas de micelles dans les conditions de stockage et qui empêchent ainsi le transport du pesticide à travers la phase aqueuse.
