Which of the following is a disadvantage of duster sprayers?

• A. Highly visible, drift easily, and difficult to control
• B. Very accurate targeting
• C. No need to calibrate
• D. Heavy and expensive

Answer: (A)

Dusting equipment disperses dry particles into a visible cloud, and those particles are light and easily carried by air currents. That makes the application drift away from the target area and be difficult to control, leading to uneven coverage and the potential for contamination of non-target surfaces or people. Because drift is a constant risk, dusters are less precise than many liquid spray methods. Calibration remains important to achieve the correct application rate, and these units are typically not heavy or expensive, so those characteristics aren’t real disadvantages.
