Using a lower spray pressure to reduce drift potential influences drift by changing what?

• A. Application Rate
• B. Droplet Quality
• C. Distance to Target
• D. Wind Speed

Answer: (C)

Drift is about how far spray droplets travel before they deposit. Lowering spray pressure tends to create larger, heavier droplets that fall out of the air more quickly, so they don’t travel as far. The key factor that changes how much drift occurs under this condition is the distance the droplets must travel to reach the target. If the target is closer, larger droplets are more likely to deposit near the nozzle with less off-target drift; if the target is farther away, even these larger droplets can drift more. Wind and nozzle choice still matter, but the direct link to reducing drift with lower pressure is the shorter travel distance required for the droplets to reach the target.
