Which sprayer does not require water to operate?

• A. Aerosol generator or fogger sprayers
• B. Hand sprayers
• C. Roller and rope-wick applicators
• D. Duster sprayers

Answer: (D)

Dusting equipment delivers dry pesticide powders, so no water or liquid carrier is needed to operate. That makes it the only option among common sprayers that can apply a product without using water. The others rely on liquid formulations: aerosol generators or foggers spray a mist from a liquid pesticide, and hand sprayers and roller/rope-wick applicators move a liquid solution (often diluted with water) to the target area. So, the duster sprayer stands out as the one that doesn’t require water.
