The higher a spray boom is held above the ground, the greater the potential for spray drift. True or False?

The higher a spray boom is held above the ground, the greater the potential for spray drift. True or False?

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Raising the spray boom increases drift potential because droplets spend more time in moving air as they travel from the nozzle toward the target. When the boom is high, wind and air turbulence can bend and carry smaller droplets off target before they deposit, increasing off-target drift. Keeping the boom lower reduces the distance droplets must travel in the airstream and often improves deposition on the target. Saying it’s false would ignore how spray drift works, and terms like “sometimes” or “not sure” don’t give a precise, actionable answer.
