Which statement best describes drift reduction additives?

• A. They increase adhesion to surfaces
• B. They decrease droplet size
• C. They increase drift by air currents
• D. They increase droplet Size and Reduce Drift

Answer: (D)

Drift reduction additives are designed to keep spray on target by making droplets larger, which lowers the chance they will be carried away by air currents. Larger droplets have more mass and tend to settle out of the air rather than drifting off-target. So the best description is that they increase droplet size and reduce drift. The idea behind drift control isn’t primarily about sticking to surfaces (that’s a retention/dropping effect) and making droplets smaller would actually increase drift, not reduce it.
