What is a disadvantage of using wettable powders (WP)?

Using wettable powders (WP) as a pesticide formulation comes with specific handling and application challenges, one of which is the need for constant agitation in the spray tank. This is crucial because wettable powders are solid particles that must remain suspended in liquid to ensure consistent distribution and effectiveness. If agitation is insufficient, these powders can settle at the bottom of the tank, leading to uneven application, reduced efficacy, and potential damage to the target area or organism being treated.

The necessity for constant agitation highlights the importance of equipment compatibility and operational management in pest control practices. This aspect distinguishes wettable powders from other formulations that might not require such rigorous handling, ultimately impacting the efficiency and success of pesticide application.
