Granular water soluble or hygroscopic agricultural formulations

A pesticidal formulation in the form of water-dispersible granule comprising:

• a solid material consisting essentially of (i) a filler/binder which is delaminated kaolin clay, (ii) a synthetic calcium silicate carrier, and (iii) a dispersing agent which is a mixture of a lignosulfonic acid of a condensed sulfonated sodium salt with polyvinylprrolidone;
• and
• a pesticidal effective amount of a salt of a water soluble or hygroscopic pesticide adsorbed onto said synthetic calcium silicate carrier, and wherein
• the granules have a particle size distribution of less than about 1.0 wt. % +8 mesh, less than about 3.0 wt. % -30 mesh and less than about 0.2 wt. % -100 mesh such that the granules have a median particle diameter size of less than about 40 microns after five minutes of non-sonic dissolution in water.
