What can be expected regarding drift if droplet sizes are reduced?

When droplet sizes are reduced in the context of aerial application of pesticides, smaller droplets have a greater tendency to be affected by environmental factors such as wind. This is due to their lower mass and higher surface area to volume ratio, which makes them more susceptible to movement in the air. As a result, smaller droplets are indeed more likely to drift away from the target area during application.

Factors such as wind speed and turbulence can easily carry these lighter, smaller droplets away, increasing the risk of non-target exposure and environmental contamination. In contrast, larger droplets tend to fall more quickly to the ground and are less affected by wind, thus reducing the likelihood of drift. Therefore, reducing droplet size increases the risk of drift, making this the correct conclusion.
