Wettable powders are pesticide formulations that require specific handling precautions, particularly due to the grinding actions involved in their application. These formulations consist of fine particles that can easily become airborne when disturbed, posing inhalation hazards to applicators if proper precautions are not taken. The grinding actions necessary to disperse these powders in water can create dust that may contain active ingredients, increasing the risk of exposure during mixing and application.

Additionally, wettable powders may require specific personal protective equipment (PPE) to minimize the risk of skin and respiratory exposure. This focus on safety is paramount when handling wettable powders to ensure the well-being of the applicator and the effectiveness of the pesticide application.

In contrast, dusts and granules, while they can also present risks, typically do not require the same level of precautions related to grinding actions because they are usually applied as-is or in larger particles that do not create significant airborne dust during handling. Emulsions involve liquid formulations that do not require grinding, thus reducing the potential for airborne particles and the associated handling concerns.
