Minimizing pesticide drift during application is crucial for both the effectiveness of the treatment and the safety of surrounding areas. Using low-pressure sprayers and large droplet sizes is essential for several reasons.

When u low-pressure sprayers are employed, the formation of smaller droplets is reduced, as higher pressure generally leads to smaller droplet sizes that are more susceptible to wind drift. Larger droplets, on the other hand, are less likely to be carried away by the wind due to their mass, thus ensuring that the pesticide reaches the intended target area more effectively and minimizes the risk of unintentionally affecting non-target areas.

Additionally, larger droplets are typically less prone to evaporation, which can further reduce drift as the pesticide can settle more quickly onto the plant surfaces. This practice not only enhances the stability of the pesticide during application but also helps in achieving better adherence and coverage on the intended vegetation, thereby maximizing the efficacy of the pesticide while safeguarding the environment and local community.
