The effects of changes in extrusion process variables upon the quality parameters of Water Dispersible Granules (WG) of insecticide Deltamethrin were studied. Deltamethrin Water Dispersible Granules composition was optimized and different batches were prepared in the laboratory with changes in major process variables viz. amount of water added into extrusion powder, rotation speed of extruder and drying temperature. The effects upon the quality of WG with respect to major quality parameters i.e. suspensibility and dispersibility were studied. The amount of water added into extrusion powder shown remarkable effects on suspensibility and dispersibility. The samples prepared with less amount of water shown better suspensibility and dispersibility and vice-versa. The extruder rotation speed also affected the quality of WG. The samples prepared at low extruder speed shown better results of suspensibility and dispersibility. The variation in drying temperature shown negligible effect upon the quality of the product
