When spraying pesticides, the ideal wind speed should be between which values?

The ideal wind speed for spraying pesticides is typically between 5 and 15 Km/h. At this range, the wind is generally adequate to help disperse the pesticide evenly, reducing the chance of droplets settling too close to the target or drifting uncontrollably off-site. This balance allows for effective application while minimizing the risk of drift, which can potentially affect non-target areas or organisms.

Wind speeds below 5 Km/h can lead to the risk of pesticide particles lingering in the air too long, increasing the likelihood of settling on non-target areas. On the other hand, wind speeds exceeding 15 Km/h introduce a higher risk of drift, making it challenging to apply the pesticide accurately to the intended area. Wind speeds above 25 Km/h are generally not suitable for pesticide application, as they can significantly complicate the control of where the pesticide lands, likely resulting in environmental contamination and reduced effectiveness of the treatment.
