Which practice helps minimize spray drift in turf applications?

• A. Keep boom height as recommended
• B. Use appropriate nozzle type and droplet size
• C. Increase spray pressure for finer droplets
• D. Apply during temperature inversions

Answer: (B)

Controlling drift comes down to the size of the droplets that leave the nozzle, which is set by the nozzle type. The nozzle determines how the liquid is broken into droplets and the resulting droplet size distribution. Larger, heavier droplets settle onto the turf quickly and are less likely to be carried off-target by the wind. So choosing an appropriate nozzle and aiming for the right droplet size directly reduces off-target movement in turf applications. Keeping the boom height within the recommended range also helps reduce drift, but it works best in combination with producing the correct droplet size; if droplets are too fine, drift can still be substantial even at the recommended height. Increasing spray pressure generates finer droplets, which actually increases drift, not minimizes it. Applying during temperature inversions raises drift risk because the air near the ground is unstable and droplets can travel farther and unpredictably.
