Which technique would minimize off-target drift?

Which technique would minimize off-target drift?

• A. What is the best time to apply pesticide?
• B. Using the smallest droplet size feasible for coverage.
• C. Which factor is most important in choosing a nozzle size for ground applications?
• D. Which technique would minimize drift? Using the largest droplet size feasible for the required coverage.

Answer: (B)

Minimizing drift hinges on spray quality, especially droplet size. Larger droplets are heavier and fall out of the air more quickly, so they’re less likely to be carried by wind or evaporate into fine particles that drift away from the target. Using the largest droplet size feasible for the required coverage keeps more product on the target area and reduces off-target movement. While timing, nozzle selection, and spray pressure can influence drift, they don’t reduce drift as reliably as adjusting to larger droplets while still achieving the needed coverage.
