When raising the boom sprayer you will tend to do what to overlap and drift?

• A. Increase overlap and reduce drift
• B. Reduce or eliminate the overlap and increase drift
• C. No change in overlap or drift
• D. It only affects nozzle wear

Answer: (B)

Raising the boom changes how the spray travels: the nozzle-to-target distance increases, so droplets spend more time in air and are more influenced by wind. This makes drift more likely. At the same time, the spray pattern widens with height, so the swath width grows and the overlap between passes decreases if you don’t adjust spacing. So you tend to reduce or eliminate overlap and see more drift. Lowering the boom or changing pass spacing can help restore overlap and reduce drift.
