Which of the following factors can help prevent spray drift?

Using larger droplet sizes is effective in preventing spray drift because larger droplets are less likely to be carried off target by wind. When pesticides are applied, smaller droplets can become airborne and drift away from the intended application area, particularly in windy conditions. Larger droplets, on the other hand, tend to fall more quickly to the ground, which helps ensure that the product reaches the target area effectively and minimizes potential off-target contamination. This practice is a key consideration in the application of herbicides, as it enhances both efficacy and safety.

While other factors mentioned might seem beneficial in theory, they either do not directly address drift concerns or could introduce other challenges. For instance, applying pesticides in sunny weather can increase evaporation rates and may not relate directly to drift management. Increasing application height can sometimes lead to more drift rather than less, as it raises the spray into windier, less stable air. Reducing wind speed at all costs is not practical and may not always be feasible, as various external conditions can affect wind speed. Thus, focusing on droplet size presents a more reliable and straightforward approach to minimizing spray drift during herbicide application.
