What is a characteristic of wettable powders (WP or SP) compared to emulsifiable concentrates?

Wettable powders (WP or SP) are formulated as fine particles that can be mixed with water to create a suspension for application. One of the key characteristics of these powders is that they typically pose lower inhalation hazards when compared to emulsifiable concentrates, which are liquid formulations that contain solvents. The physical form of wettable powders reduces the potential for airborne particles to be inhaled during handling and application since they are formulated to be mixed with water, leading to less dust being generated.

Additionally, when properly mixed, the application of a slurry created from wettable powders results in a more controlled and directed application, which further minimizes the risk of inhalation. This is particularly important for ensuring the safety of applicators, as exposure to pesticide vapors or aerosols from liquid formulations can be higher than for dry powders.
