Which criterion is used to evaluate how well the spray reaches the target area?

• A. Amount of Spray Applied
• B. Uniformity of the Spray
• C. Coverage of the Target
• D. Potential for Spray Drift

Answer: (C)

Coverage of the Target describes how thoroughly the spray wets the surfaces of the target area. It’s the best measure of reach because it directly shows how much of the pest habitat actually receives product, which drives effectiveness. The amount of spray applied tells you how much liquid you’re putting out, and uniformity of the spray tells you whether droplets are spread evenly, but neither alone guarantees that the entire target is contacted. Spray drift concerns off-target movement and can reduce reach, but it doesn’t measure how much of the target was actually covered. To improve coverage, you’d adjust nozzle type, spray pressure, speed, and droplet size to deposit droplets across as much of the target as possible.
