Developing a Fast-dispersing Extruded Water-dispersible Granule Challenge A research-based agrochemical producer came to us with an apparently simple challenge: developing an extruded granule that dispersed as fast as spray-dried water-dispersible granules (WGs). Solution Our team began by examining why traditional WG materials like China clay filler and surfactants failed to yield quick-dispersing extruded granules. Then we investigated replacing the traditional inert materials with alternatives. After studying and testing a number of substitutes, the team discovered the most suitable new filler and surfactant combination—one that resulted in an extruded granule with a rapid rate of dispersion, both initially and after storage. Outcome In addition to rapid dispersion (2-3 inversions for c
