When raising the boom sprayer you...

• A. Increase overlap and reduce drift
• B. Reduce overlap and increase drift
• C. No effect on overlap or drift
• D. Increase coverage

Answer: (B)

Raising the boom widens the spray swath. With the same nozzle spacing and travel path, a higher boom means the pattern covers a larger ground width, so the overlap with the next pass decreases. At the same time, droplets have to travel farther to reach the target, giving air currents more time to carry them off target, which increases drift. So the two effects align: reduced overlap and increased drift. Increased coverage per pass is not the main outcome here, and the drift risk makes higher height less favorable for precise, targeted application.
