Which weather factors reduce drift?

The correct answer is based on the understanding of how specific weather conditions influence the behavior of sprayed pesticides in the air. Lack of wind helps to minimize drift, as wind can carry droplets away from the target area. Low temperatures generally lead to denser air, which can help keep pesticide particles closer to the ground rather than allowing them to disperse. High humidity, on the other hand, can cause droplets to remain larger for a longer period, thereby reducing the likelihood of evaporation and drift. When these three conditions—lack of wind, low temperatures, and high humidity—are present, the potential for pesticide drift is significantly decreased, leading to better application effectiveness and reduced environmental impact.
