Which droplet size provides better coverage but is more likely to drift?

• A. Larger
• B. Medium
• C. Very Large
• D. Smaller

Answer: (D)

Smaller droplets are the ones that provide better coverage on the target because there are more individual droplets landing across surfaces, increasing the chance that the pesticide reaches and sticks to more of the leaf or effective area. But these tiny droplets are light and easily carried by air currents, so they are more prone to drifting away from the target zone, especially if wind is present or if application conditions favor movement.

In contrast, very large or coarse droplets tend to settle quickly with less drift, but they don’t cover as thoroughly because there are fewer droplets reaching and distributing over the target surfaces. That's why the small droplets option is the one that balances enhanced coverage with a higher drift risk.

When applying, consider factors like wind speed, spray pressure, nozzle type, and height above the target to manage drift while achieving satisfactory coverage.
