As droplet size decreases, the effect on coverage and drift potential is that coverage increases and drift potential increases. Smaller droplets are more easily dispersed by wind and other atmospheric conditions, leading to a greater potential for drift. This means that when applying pesticides with smaller droplets, they can travel farther from the target area due to being more susceptible to environmental factors.

Additionally, because these smaller droplets can spread over a larger area, they often lead to increased coverage of the target surfaces. This is particularly important in forestry applications where achieving uniform coverage on foliage is crucial for the effectiveness of the pesticide. However, the increased risk of drift can pose ecological concerns and may affect non-target areas, emphasizing the need for careful application techniques.
