How do soluble powders (SP) differ from wettable powders (WP)?

Soluble powders (SP) are designed to dissolve completely in water, creating a solution that can be easily applied. This property allows for uniform distribution of the active ingredient in the solution, making it effective for use in various application methods. In contrast, wettable powders (WP) do not dissolve completely; instead, they must be agitated to remain suspended in water, as they tend to settle at the bottom of the tank if left undisturbed.

The option about SP being more hazardous than WP is not universally accurate, as the toxicity depends on the specific chemicals involved rather than the formulation type. While it is true that some SP formulations may require more careful handling, this does not inherently apply to all SP products and does not serve to distinguish them from WP in terms of formulation characteristics.

The requirement for more agitation with SP compared to WP is inaccurate because, once dissolved, SP does not require further agitation like WP does, which needs constant stirring to prevent sedimentation. Lastly, the claim that SP comes in liquid form is incorrect, as both SP and WP are powder forms, with the distinction lying in their solubility in water.

Thus, the key difference lies in the complete dissolution of SP versus the partial suspension of WP in
