What is the best time for making an aerial application of a liquid when evaporating droplets is a concern?

The best time for making an aerial application of a liquid when evaporating droplets is a concern is during the early morning. At this time, temperatures are typically cooler and humidity levels are generally higher, creating conditions that minimize evaporation. This means that droplets are more likely to remain intact and settle effectively on the target area, rather than evaporating into the atmosphere before reaching the intended surface.

In contrast, late afternoon and midday often present warmer temperatures and lower humidity, resulting in higher evaporation rates that can lead to loss of material before it can be effective. Evening might also be less suitable, as temperatures can still be warm and evaporation may still occur, particularly if there is a breeze or if temperatures are slowly cooling down. Therefore, the early morning is preferred for aerial applications when minimizing evaporation is crucial.
