What describes Wettable Powder (WP or W)?

• A. A dry material made of active ingredient and formulant; contains a wetting and dispersing agent; mixed with water to form a suspension
• B. A granule that dissolves in water to form a true solution
• C. A pellet that is easy to spot treat
• D. A soluble powder that dissolves completely in water

Answer: (A)

Wettable powder is a dry, finely ground formulation that includes an active ingredient and additives. When you mix it with water and agitate, the powder doesn’t fully dissolve; it forms a stable suspension of tiny particles. Wetting and dispersing agents help the particles break the surface tension of the water and spread evenly, so the mixture can be sprayed uniformly. This contrasts with soluble powders, which dissolve completely to form a true solution, and with granules or pellets that are not meant to dissolve and are often used for spot treatments. Because it remains as suspended particles, you must shake or agitate the mixture during use to keep it evenly dispersed and to prevent clogging or uneven coverage.
