Which scenario would be most likely to increase spray drift risk?

• A. Wind velocity 11 mph toward a sensitive area
• B. Wind velocity 6 mph toward a sensitive area
• C. Wind velocity 3 mph away from sensitive area
• D. Wind velocity 15 mph away from sensitive area

Answer: (A)

Spray drift is driven by how air carries the droplets after application. The faster the wind, and the more it blows toward a sensitive area, the more likely droplets will be carried off-target into that area. Among these scenarios, the wind moving at 11 mph toward a sensitive area creates the strongest combination of measurable drift potential and direct toward-target exposure, so it poses the greatest drift risk. The other options either involve slower wind toward the area (less drift), wind away from the area (reduces exposure to that sensitive site), or a strong wind but blowing away (high drift risk off-target somewhere else, but not toward the sensitive area). Thus, 11 mph toward a sensitive area is the scenario most likely to increase spray drift risk.
