Abstract
The present invention relates to microcapsules containing water-insoluble, liquid active ingredients or mixtures thereof, which are employed principally in the sector of plant protection and in which the solvent which is likewise present within the capsule is a liquid substance comprising two or more aromatic rings. The microencapsulation of plant protection agents, especially the envelopment of water-insoluble, liquid or solid active particles in water-based mixed-phase systems, has developed in recent years to become a standard formulation technique.
