What is required for Wettable Powders (WP) to remain effective in a spray tank?

• A. Suspended particles require good and constant agitation in the spray tank.
• B. No agitation is required.
• C. Heat the spray tank before mixing.
• D. Add water after mixing.

Answer: (A)

Wettable powders are dry, finely ground materials that must stay dispersed in water to form a uniform spray. In a spray tank, those suspended particles will settle to the bottom if there’s no ongoing stirring, which leads to clogging, uneven concentration, and poor pest control. Keeping the solution in suspension requires good and constant agitation or mixing throughout mixing and application, so the powder stays evenly distributed until it’s sprayed. Heating the tank isn’t needed and can cause other issues, and adding water after mixing would not prevent settling—so it wouldn’t keep the WP effective.
