What characteristic defines wettable powders?

Wettable powders are defined as finely ground solids that are intended to be mixed with water for spraying applications. This characteristic is critical because wettable powders are often used in agricultural and pest control scenarios where effective distribution of the pesticide or herbicide is necessary. When mixed with water, these powders form a suspension, allowing them to be evenly distributed over the target area during application.

This form allows for more precise control and coverage compared to other formulations, such as liquids, which may not adhere as well to certain surfaces. Understanding the nature of wettable powders is essential for anyone involved in pesticide application, as it influences how the product is mixed, stored, and used effectively to achieve desired pest control outcomes. Additionally, proper agitation is required when using these powders for a uniform mixture, setting them apart from formulations that do not require such action.
