When is the best time to treat end rows and field edges?

Treating end rows and field edges when drift potential is minimal is optimal for several reasons. First, managing drift is critical in aerial application because it ensures that the product is applied efficiently to the intended target while minimizing unintended exposure to neighboring crops, wildlife, or sensitive areas.

When drift potential is low, typically during conditions with stable air and low winds, there is a reduced likelihood that the pesticide or fertilizer will be carried off-target by wind or air movement. This ensures that the application is more effective and decreases the chances of environmental contamination or damage.

In contrast, conditions like midday heat can create turbulent air that may increase drift, while treatments at dawn or dusk may still have higher humidity levels or the potential for temperature inversions, which can also affect drift patterns. Therefore, the timing for treatment should be carefully considered to achieve the best results while maintaining safety and compliance with regulations.
