Which formulation is characterized as a Wettable Powder?

  1. WP

  2. WG

  3. DF

  4. SC

The correct answer is: WP

Wettable Powder formulations are characterized by their ability to disperse in water to create a suspension, which can then be applied as a spray. These formulations consist of finely ground solid particles that require agitation to remain mixed with water during application. The designation "WP" stands for "Wettable Powder," indicating that this particular formulation is designed to be mixed with water for effective application. In contrast, other formulations have different characteristics. For instance, "WG" refers to Water Dispersible Granules, which dissolve in water but are slightly different in handling and application. "DF" stands for Dry Flowable, which also requires water but has distinct particle properties. "SC" refers to Suspension Concentrate, where the active ingredient is suspended in a liquid carrier. Understanding these distinctions helps in selecting the appropriate formulation for specific pest control needs, ensuring effective application methods based on the product's characteristics.
