Which of the following is NOT a method to minimize drift?

• A. Spray at low pressure
• B. Use smallest practical nozzle openings
• C. Use spray additives
• D. Spray when winds are calm

Answer: (B)

Drift happens when spray droplets are carried away from the target by air movement, so practices that produce larger droplets and reduce airborne transport help minimize it. Spraying at low pressure tends to create coarser droplets that settle faster, cutting down on how far they travel. Using spray additives can increase droplet size or improve deposition, further reducing drift. Spraying when winds are calm minimizes the chance droplets will be blown off course. Choosing the smallest practical nozzle openings makes finer droplets that are more easily swept away by air, which increases drift rather than reduces it, so that approach does not minimize drift.
