In pesticide application, what is a primary reason for using smaller droplet sizes?

Using smaller droplet sizes in pesticide application is primarily advantageous because it allows for increased coverage on the target area. Smaller droplets can disperse more evenly and penetrate into the vegetative canopy, ensuring that the pesticide makes contact with a greater surface area on the plants or weeds intended for control. This enhanced coverage can lead to more effective results, as the active ingredient has more opportunities to interact with the pests or target plants.

While options such as reduction of pesticide usage and less drift potential may also be associated with smaller droplet sizes, the primary reason remains the increased coverage. Smaller droplets can cover intricate surfaces better and reach areas that larger droplets may miss, which is crucial for effective pest management.
