What is typically the effect of applying pesticides during high wind conditions?

Applying pesticides during high wind conditions primarily leads to increased drift. When wind speeds are high, the active ingredients in the pesticides can be carried away from the intended target area, resulting in a spread that can affect non-target plants, wildlife, and even nearby water sources. This drift not only diminishes the effectiveness of the application—because the pesticides may not reach the intended pests or plants—but it may also lead to environmental contamination and regulatory concerns.

Increased drift compromises the application process and often necessitates corrective action to address the unintended consequences, which can include additional costs or the need for reapplication in calm conditions. Thus, managing the timing and weather conditions during which pesticides are applied is critical for maintaining efficacy and ensuring safety.
