Production Method of Water Dispersible Granule
Forming an aqueous suspension comprising discrete microcapsules containing at least one water-insoluble pesticide within a polymeric shell wall suspended in an aqueous liquid. Forming droplets of said aqueous suspension and spray drying said droplets to form essentially spherical water-dispersible granules which are from about 150 to about 850 microns in diameter and which contain up to about 8.0% moisture, wherein each water-dispersible granule is an aggregation of said microcapsules.
Safety Information of Water Dispersible Granule
Granules with water in a handheld sprayer. Before mixing and applying, wear the necessary ppe for safety.
