Which item helps keep wettable powders in suspension?

• A. Agitator
• B. Filter
• C. Pressure gauge
• D. Pump

Answer: (A)

Keeping wettable powders evenly distributed in a spray tank requires constant mixing so the solid particles don’t settle out. An agitator provides that essential mechanical mixing, circulating the liquid and keeping the powders suspended throughout the spray operation. This helps prevent settling, clogging, and uneven application. A filter would tend to trap particles or clog, not keep them in suspension. A pressure gauge only measures pressure. A pump moves the liquid but doesn’t by itself maintain suspension of solids.
