Formulations of water-dispersible granules and process for preparation thereof

The invention herein relates to dry flowable water-dispersible granular formulations and to a process for the preparation thereof. In particular, the water-dispersible granular formulations of this invention comprise a mixture of aggregates of microcapsules of water-insoluble pesticide, e.g., alachlor, or a plant growth regulant encapsulated within a polymeric shell wall and at least one other pesticide, e.g., atrazine or a salt of glyphosate, which is non-encapsulated. The water-dispersible granular formulations of the invention are prepared by mixing appropriate quantities of an aqueous dispersion of the encapsulated component, the non-encapsulated component and formulation adjuvants to form a slurry of the desired viscosity which can be directly extruded than dried or the slurry in more dilute, less viscous form may be spray dried, or agglomerated in fluid beds or rotating disc agglomerators.
