Excessive drift is most directly caused by which nozzle placement?

• A. The nozzle tips are worn
• B. The pump is malfunctioning
• C. The spray pressure is too high
• D. The nozzles are positioned too far from the target

Answer: (D)

Excessive drift happens when spray droplets stay airborne long enough to be moved off target by wind, and the distance between the nozzle and the target directly controls how long droplets remain in the air. When nozzles are positioned too far from the target, droplets travel a longer distance before deposition, giving air currents more opportunity to carry them away and reducing the chance they deposit where intended. This makes drift more likely. To minimize drift, keep nozzles at the recommended height above the target and choose appropriate nozzle types and droplet sizes, while spraying in suitable weather and following label instructions. Other issues like worn nozzle tips or a malfunctioning pump can affect spray quality or pressure, and high spray pressure can create finer droplets that drift more, but the placement itself is the direct driver of drift in this scenario.
