What is the optimum time for making aerial applications when droplet evaporation is a concern?

Making aerial applications early in the morning is ideal when droplet evaporation is a concern due to lower temperatures and humidity levels typically present at that time. During early morning hours, the air is generally cooler and more saturated with moisture, allowing for larger droplets to remain intact for longer periods before they evaporate. This helps in ensuring better coverage of the treated area and reduces the potential for pesticide drift caused by rapid evaporation of smaller droplets. It also takes advantage of the generally calmer winds that are common in the early morning, further promoting effective application. In contrast, as the day progresses, temperatures rise and air becomes drier, which can increase evaporation rates and negatively affect the efficacy of the application.
