Regular flat-fan nozzles require what percentage pattern overlap for uniform coverage?

• A. 30% to 50% pattern overlap
• B. 10% overlap
• C. 70% to 80% overlap
• D. 0% overlap

Answer: (A)

Uniform spray coverage with flat-fan nozzles depends on how much the spray patterns from adjacent nozzles overlap. The recommended overlap is about 30% to 50%, which provides enough superimposition so every point in the target area receives spray from more than one nozzle, smoothing out spacing and distance variations. This range helps achieve even deposition across the treated surface without creating excessive wetting that can lead to runoff or foliar damage. If the overlap is only 10% or 0%, gaps appear between swaths and coverage becomes uneven; if it’s very high, like 70% to 80%, areas receive double coverage and can suffer from over-application and potential waste or leaf burn.
