Smaller slower droplets are more susceptible to what compared to larger droplets?

Smaller, slower droplets are indeed more susceptible to evaporation compared to larger droplets. This is largely due to the surface area-to-volume ratio; smaller droplets have a higher surface area relative to their volume, which allows them to lose moisture more quickly. When a droplet evaporates, the liquid transforms into vapor, and because smaller droplets have more surface area exposed in relation to their size, they can evaporate at a faster rate.

Additionally, the environmental conditions, such as temperature and humidity, play a crucial role in evaporation. As smaller droplets drift through the air, they may encounter varying conditions that can result in rapid evaporation, potentially reducing the effectiveness of a pesticide application.

In contrast, larger droplets tend to retain more liquid because of their lower surface area-to-volume ratio, making them less vulnerable to evaporation. Understanding the properties of droplet size is essential for optimizing pesticide application and ensuring that the treatment remains effective on target areas.
