What spray-drift reduction practice is recommended?

• A. High pressure and low volume
• B. Low pressure high volume
• C. No adjuvant
• D. Fine droplets

Answer: (B)

Reducing spray drift comes from creating larger droplets and delivering them in a way that keeps the spray where you want it. Operating at low pressure slows the spray and tends to produce coarser droplets, and using a higher volume helps ensure good coverage on the target without relying on fine droplets. Together, low pressure with high volume minimizes drift while still delivering enough product to the target.

Using high pressure and low volume makes finer droplets that are more easily carried by the air, increasing drift. Not using an adjuvant doesn’t actively reduce drift, and fine droplets are the opposite of drift-reducing practice, since they drift more readily.
