Before producing the final granules a paste must be made. Wetting agents help incorporate the liquid components into this paste. They also reduce drying costs after the granules have been made as less water can be used. On dilution in water prior to application, wetting agents help disintegration and prevent nozzle blockage.
Once the granule has been diluted in water, ready for spraying (with the aid of the wetting agent), a dispersant is required to maintain the particles in suspension and prevent them from agglomerating.
To increase the efficacy of the WDG formulation adjuvants can be included.
