ABSTRACT:
The invention is directed to a pesticide composition comprising free flowing, essentially spherical, water-dispersible granules wherein said water-dispersible granules are from about 150 to about 850 microns in diameter; wherein said granules contain up to about 8.0% by weight moisture; wherein each individual water-dispersible granule is an aggregation of individual spherical microcapsules which contain at least one water-insoluble pesticide within a polymeric shell wall; and wherein said water-dispersible granule disintegrates upon contact with water to release said individual microcapsules.
The invention also relates to dry flowable pesticidal formulations of the above water-dispersible granules, together with formulation adjuvants.
The invention is further directed to a process for preparing a water-dispersible granule by spary drying an aqueous suspension comprising discrete microcapsules containing at least one water-insoluble pesticide within a polymeric shell wall suspended in an aqueous liquid.
