What is the purpose of drift control adjuvants?

Drift control adjuvants are designed specifically to minimize pesticide drift during application. By increasing droplet size, these adjuvants ensure that more of the pesticide falls to the intended target area rather than being carried away by wind or air currents. Larger droplets are less likely to be affected by wind forces, thereby reducing the potential for off-target application and unintended environmental consequences. This is particularly important in agricultural settings as it helps protect non-target plants, wildlife, and nearby communities from exposure to pesticides.

The other options address concepts that may not align with the primary concerns of drift control. Enhancing pesticide smell, accelerating evaporation, or increasing the cost of application do not contribute to the goal of reducing drift. Instead, they could create additional challenges or issues not aligned with effective and safe pesticide application practices.
