Which method can reduce pesticide drift?

Reducing the pressure of the spray nozzle is an effective method for minimizing pesticide drift. Lowering the pressure decreases the energy with which the pesticide is released from the nozzle, resulting in a larger droplet size. Larger droplets are more likely to settle quickly to the target surface rather than being carried off by wind or air currents. This control over droplet size is crucial for preventing off-target application, which can lead to environmental contamination and unintended effects on non-target organisms.

In contrast, practices such as increasing the speed of application or applying during windy conditions are likely to exacerbate drift, as they introduce factors that facilitate the dispersal of smaller droplets. Therefore, focusing on reducing nozzle pressure assists in creating a more concentrated application, improving efficacy and safety. Other methods that involve ensuring appropriate droplet size and selecting optimal application conditions also contribute to effective drift management.
