Using larger droplets in a spray application leads to less coverage when compared to smaller droplets. Larger droplets tend to fall more quickly to the ground, which results in a less uniform distribution across the target area. This can prevent the active ingredient from reaching all the surfaces where it is needed, especially in dense foliage or when trying to treat a varied landscape. Consequently, the application may not effectively cover all areas, leading to gaps where treatment is lacking, which can result in reduced effectiveness of pest control measures.

In contrast, using smaller droplets can enhance coverage, as they are more likely to spread out and penetrate into intricate spaces and lessen the risk of being affected by wind drift. Therefore, while large droplets can benefit some aspects of an application in certain scenarios, in general, they may compromise the thoroughness of coverage needed for optimal results.
