How are Wettable Powders typically used?

Wettable Powders are designed to be mixed with water to create a suspension for application. When these powders are added to water, they do not fully dissolve but instead form a suspension, which needs to be agitated to ensure that the particles remain evenly dispersed. This is important because if the suspension sits for too long without agitation, the particles can settle at the bottom, leading to uneven distribution during application. Proper mixing and agitation prior to use ensure that the active ingredients are effectively delivered to the target pests or plants, enhancing the product's effectiveness.

The other options do not accurately describe the correct use of Wettable Powders; for instance, dissolving in water implies complete solubility, which is not the case. Applying directly without dilution goes against the method of use, as these products require mixing with water to function properly. Lastly, mixing with oil is not a standard practice for Wettable Powders, which are specifically formulated for water-based applications.
