Wettable Powder must be mixed with what to form a suspension for application?

• A. Water
• B. Oil
• C. Alcohol
• D. Glycerin

Answer: (A)

Wettable powders are solid particles that don’t dissolve in water, so they are dispersed in water to create a sprayable suspension. Water serves as the carrier that wets and distributes the powder evenly in the spray, allowing the droplets to carry the active material to the target. Using oil, alcohol, or glycerin would not provide the proper dispersion or spray performance: oil doesn’t wet the particles well and doesn’t mix evenly, alcohol can cause rapid evaporation and potential compatibility issues, and glycerin is too viscous for typical spraying. By mixing with water and keeping the solution well-agitated, you get a uniform suspension suitable for application.
