To decrease overlap, you should

• A. Raise boom
• B. Move to a distant field
• C. Increase spray rate
• D. Lower boom

Answer: (D)

Controlling how wide the spray swath is from each pass is what governs overlap. Lowering the boom to the recommended height keeps the ground spray pattern narrower and more concentrated along each pass, so the next pass is less likely to double up on the same ground area. Raising the boom widens the swath and increases the chance that a portion of the previous pass will be treated again. Moving to a distant field doesn’t change the spacing of passes, and increasing the spray rate changes how much chemical is applied but not how the swath overlaps between passes. So lowering the boom is the best way to decrease overlap.
