What is considered the optimum time for aerial applications when avoiding droplet evaporation?

The optimum time for aerial applications to minimize droplet evaporation is early morning. During this period, temperatures are typically cooler, and humidity levels are higher compared to other times of the day. Cooler temperatures help keep the droplets larger and reduce their evaporation rates as they are released into the air. Additionally, higher humidity levels contribute to maintaining moisture in the air, which is crucial in preventing the droplets from evaporating before they reach the target area.

In contrast, late afternoon and noon often feature higher temperatures and lower humidity, which can significantly increase the rate of evaporation and reduce the efficacy of the application. Evening may also lead to changes in temperature and air stability that could impact the performance of the spray but is generally more favorable than late afternoon or noon. However, early morning is widely recognized as the best time for applications to ensure that the spray reaches its intended destination effectively.
