Increasing the pump pressure increases the likelihood of drift due to smaller droplets.

• A. True
• B. False
• C. Only increases if wind is present
• D. Drift is not affected by droplet size

Answer: (A)

Droplet size drives drift risk: finer droplets stay in the air longer and are more easily carried by air movement, so they travel farther from the target area. Pump pressure affects atomization: increasing the pressure generally produces smaller droplets. So, raising pump pressure tends to increase drift likelihood because it creates more of those small droplets that float on air currents. Wind can amplify this effect, but it isn’t required for drift to occur. The other statements don’t fit because drift is indeed influenced by how small the droplets are, and it isn’t limited only to windy conditions.
