Which statement correctly describes a wettable powder (WP) formulation?

• A. It is a liquid concentrate.
• B. It is a water phase formulation.
• C. It stands for Water Phase.
• D. It stands for Wettable Powder.

Answer: (D)

Wettable powders are dry, finely milled pesticide formulations designed to be mixed with water to form a suspension. The acronym WP literally stands for Wettable Powder, so this choice correctly identifies what the formulation is called. It isn’t a liquid concentrate, nor a water-based/ water phase formulation, which is why those descriptions don’t fit. In practice, a WP includes the active ingredient plus inert carriers and wetting/dispersing agents so that when you stir it into water, the powder wets and disperses to form an evenly suspended spray. It’s a solid form that relies on proper mixing and agitation to stay evenly distributed, unlike ready-to-use liquids or water-phase systems.
