What is the reason for avoiding inversions during pesticide application?

Inversions refer to a meteorological phenomenon where a layer of warm air traps colder air at the surface, preventing vertical mixing of the atmosphere. This condition can significantly affect the dispersion of airborne substances, including pesticides.

When an inversion occurs, it creates a stable layer that holds pollutants, including pesticide particles, close to the ground instead of allowing them to disperse. As a result, this can lead to increased drift potential. Pesticides that might otherwise be safely applied can instead become concentrated in areas where they are not intended to be used, potentially affecting nearby crops, wildlife, or human populations.

Therefore, avoiding inversions during pesticide application is crucial to minimize environmental contamination and ensure that the pesticide reaches its intended target effectively and safely.
