CA 2408397
The invention relates to the combination of an anionic agrochemical active agent and a cationic polymer, producing electrostatic interaction for the controlled release of the active agent. Said polymer preferably has cationic quaternary nitrogens. The inventive combinations or agrochemical formulations containing these combinations enable the prevention of antagonistic interactions between different active agents and allow an increase in the crop selectivity of individual active agents.
L'invention concerne la combinaison d'un principe actif agrochimique anionique avec un polymère cationique, avec production d'une interaction électrostatique pour le dégagement contrôlé de ce principe actif. Ce polymère comprend de préférence des azotes quaternaires cationiques. Les combinaisons selon l'invention ou les formulations agrochimiques contenant ces combinaisons servent à supprimer des interactions antagonistes entre différents principes actifs, ainsi qu'à augmenter la sélectivité de culture de principes actifs individuels.
