What does "light and variable" wind conditions indicate for pesticide application?

"Light and variable" wind conditions suggest that wind speeds are low and the direction of the wind may change frequently. This variability creates challenges for pesticide application because it increases the uncertainty surrounding the drift of pesticide particles. The inconsistency in wind direction means that there is a higher likelihood that the pesticide could drift away from the intended application site, potentially affecting non-target areas.

In this context, options focusing on predictability, management of drift, or the absence of buffer zones do not align with the inherent unpredictability of light and variable winds. Similarly, while inversions might coincide with certain atmospheric conditions, the primary concern during pesticide application under "light and variable" winds is the uncertainty regarding the direction of drift, making it critical to assess this aspect when planning the application.
