A process for the preparation of a solid formulation of a crop protection agent which comprises co-extruding an active ingredient with polyvinylpyrrolidone, subsequently cooling the extrudate until brittle and then milling. The resulting, often granular, formulation may be used as such, pressed into tablet form or agglomerated into larger granules, each of which forms rapidly disperse on dilution with water and give a biological activity equal to commercial emulsion concentrates without the undesirable solvents associated therewith.
