What is the recommended range for nozzle height above turf canopies to minimize drift?

• A. 6–12 inches
• B. As low as practical, typically around 12–24 inches above the canopy depending on equipment and label
• C. 36–48 inches
• D. 60–72 inches

Answer: (B)

Keeping nozzle height as low as practical above the turf maximizes deposition on the target and minimizes drift. By placing the spray closer to the canopy, droplets have less distance to travel in the air and are less likely to be carried away by wind, which means more of the product lands where you want it. In practice, a height around 12 to 24 inches above the canopy is typical, though you should adjust to fit the equipment you’re using and the product’s label requirements. The label often specifies a permissible range and may set minimum or maximum heights to ensure proper coverage and safety, so following that guidance is essential. Going higher than the recommended range increases drift risk and reduces coverage, while going too low may cause issues with nozzle obstruction or uneven spray if the canopy is dense.
