Excessive drift is most directly caused by which nozzle placement?

• A. The nozzles are positioned too far from the target
• B. The nozzles are positioned too close to the target
• C. The nozzles are too close to the ground
• D. The nozzles are angled downward too steeply

Answer: (A)

Drift happens when spray droplets move with air currents away from the target. If the nozzles are too far from the target, droplets spend more time in the air and are more easily carried off-target by wind, increasing drift and reducing deposition on the plants. Being closer to the target minimizes the time droplets spend airborne, so drift is less likely. The other placements can affect coverage and deposition in different ways, but the primary way to increase drift is increasing the distance from target.
