A thin sheet of spray with uniform deposits across its band width is best described as which pattern?

• A. Even flat-fan pattern
• B. Drift-reduction additive
• C. Vapor drift
• D. Droplet Spectrum

Answer: (A)

Uniform deposition across the width of the spray band is what an even flat-fan pattern delivers. A flat-fan nozzle releases spray in a relatively flat, sheet-like spray, spreading evenly from edge to edge so the spray lands as a uniform band on the turf. That consistent coverage is exactly what a thin sheet of spray with uniform deposits across its band width describes.

Drift-reduction additives are chemicals added to the spray to limit movement of droplets in the air, not a description of how the spray lands. Vapor drift refers to the movement of volatile components after application, not the pattern of deposition on the ground. Droplet spectrum describes the range of droplet sizes produced, which influences drift and coverage but doesn’t by itself define uniformity across the band.
