Which factor does not influence pesticide drift?

Pesticide drift refers to the movement of pesticide particles or droplets away from the intended application site, and several factors can contribute to this phenomenon. Among the options provided, pollution is the factor that does not influence pesticide drift.

Wind speed is a significant factor because higher winds can carry pesticide particles further away from the target area during application. Temperature affects the volatility of pesticides and can influence how quickly they evaporate and disperse into the air. The application method plays a crucial role as well; for example, certain methods like aerial spraying or using fine droplets can increase the potential for drift compared to ground applications or using larger droplets.

In contrast, pollution does not directly affect the mechanics of how pesticides drift. While environmental conditions can influence overall air quality and the dispersal of various contaminants, pollution itself does not facilitate or contribute to the movement of pesticides after they have been applied. Therefore, it is accurate to conclude that pollution is not a factor influencing pesticide drift.
