Which of the following droplet sizes is less likely to experience drift?

Larger droplets are less likely to experience drift because they are heavier and more affected by gravity. When droplets are larger, they have a greater mass, which means they will tend to fall to the ground more quickly rather than being carried away by wind. Drift occurs when smaller particles or droplets remain airborne and can be moved by air currents, making them more susceptible to unintended application on nearby areas. Larger droplets settle more effectively in the target area, minimizing the potential for drift and ensuring that the herbicide is applied where it is intended, leading to more efficient and effective weed control.

This characteristic of larger droplets is particularly important in herbicide application, as it helps to reduce off-target pesticide movement, which can lead to environmental damage or harm to non-target plants and wildlife. Thus, employing larger droplet sizes during application can enhance both efficacy and safety.
