What does the abbreviation 'WP' stand for in pesticide formulation?

The abbreviation 'WP' in pesticide formulation stands for Wettable Powder. Wettable powders are a type of formulation that consists of finely ground solid particles that are mixed with water to create a suspension. These formulations are designed to be mixed with water and applied as a spray, allowing the active ingredient to remain effective while also being easy to handle and store.

Wettable powders are typically used for the application of pesticides because they can improve the distribution and absorption of the active ingredient when applied to plants or surfaces. This formulation can also help reduce the risk of runoff and improve adherence to target surfaces.

In contrast, water-soluble powders dissolve completely in water, which is not what WP indicates. Waxy paste and waterproof products refer to different types of formulations that do not align with the 'WP' abbreviation in pesticide contexts. Therefore, Wettable Powder is the correct definition for 'WP' in this scenario.
