Which nozzle type is more likely to produce drift-prone particles?

Which nozzle type is more likely to produce drift-prone particles?

• A. Medium
• B. Fine
• C. Coarse
• D. Ultra-fine

Answer: (B)

Smaller droplets are more easily carried by air currents, stay airborne longer, and are more prone to drift beyond the target area. A fine nozzle produces smaller droplets than a medium or coarse nozzle, so it has a higher drift potential. Coarser droplets are heavier and tend to settle faster, reducing drift. Within these options, the fine category best represents droplets with greater drift risk, making it the best choice. To minimize drift, using coarser droplets when appropriate, applying in calm wind conditions, and employing drift-reduction practices can help.
