What is the recommended practice for pesticide application on windy days?

Delaying application until wind speed decreases is the recommended practice for pesticide application on windy days because high winds can cause pesticide drift, which is the movement of pesticide particles away from the target area. Drift can lead to unintended exposure to non-target plants, wildlife, and even humans, creating potential safety and environmental concerns.

When the wind is too strong, it becomes much harder to control where the pesticide will land, increasing the risk of drift. By waiting for wind conditions to be more favorable, applicators can ensure that the pesticide is applied more accurately, reducing the likelihood that it will disperse off-target.

In contrast, using larger droplets may minimize drift but doesn't eliminate the risks associated with applying under windy conditions. Increasing pesticide concentration or applying at higher speeds can further exacerbate drift and cause harm to the environment and surrounding areas. Thus, choosing to postpone application until conditions improve is the safest and most effective approach for responsible pesticide use.
