What is the best time for making an aerial application when droplet evaporation is a concern?

Choosing early morning as the best time for making an aerial application when droplet evaporation is a concern is based on several environmental factors. During the early morning hours, temperatures are typically at their lowest, and humidity levels are usually higher. These conditions significantly reduce the rate of droplet evaporation, thereby allowing more of the applied material to reach its intended target effectively.

In the early morning, the air is often more stable as well, which means that the wind is generally calmer and less turbulent compared to other times of the day. This further enhances the accuracy of the application, as droplets can settle more precisely on the target area instead of being carried away by strong winds or evaporating before reaching the ground.

In contrast, late afternoon and early evening usually see rising temperatures and, at times, decreasing humidity, which can increase evaporation rates. Midday is often characterized by the highest temperatures and significant solar radiation, creating a windy and dry environment that is less than ideal for aerial applications when evaporation must be minimized.
