Which formulation typically requires more agitation during preparation?

The formulation that typically requires more agitation during preparation is wettable powders. These products are composed of finely ground solid particles that do not dissolve in water but instead disperse when mixed. Because of their small particle size, wettable powders have a tendency to settle at the bottom of the container if not properly stirred or agitated during mixing. This settling can lead to an uneven application of the pesticide if the mixture is not adequately agitated before or during the application process. Thus, maintaining consistent agitation is essential to ensure that the product remains uniformly suspended in the solution.

In comparison, flowables, while they also may require some agitation, tend to be more stable due to their liquid-like consistency. Pellets, being solid and larger in size, typically do not require significant agitation as they are easier to handle and distribute. Soluble powders absorb moisture and dissolve in the water without needing as much agitation, thus reducing the overall effort in mixing compared to wettable powders.
