Which of the following factors can lead to an increased pesticide drift?

High temperatures can significantly contribute to increased pesticide drift for several reasons. When temperatures rise, the volatility of certain pesticide formulations may increase, causing them to vaporize more readily. This can result in smaller droplets becoming airborne and drifting beyond the targeted application area.

Moreover, high temperatures can also lead to lower humidity levels, which can exacerbate evaporation and increase the risk of drift. Understanding the environmental conditions during pesticide application is crucial for minimizing drift, and high temperatures create an environment that is conducive to it.

In contrast, low wind speeds are typically associated with reduced drift, as they provide a more stable atmosphere for the pesticide to settle where it is applied. High water volumes usually result in larger droplet sizes, which tend to fall more directly to the ground rather than drift. Overlapping swaths, while they can lead to increased deposition, do not inherently cause drift; instead, they focus application in specific areas. Therefore, among the choices, high temperatures stand out as a key factor in promoting pesticide drift.
