What could happen if pesticide droplets are excessively large during application?

When pesticide droplets are excessively large during application, one of the primary issues is that they may not effectively adhere to the targeted surfaces. Pesticide effectiveness is closely linked to the size of the droplets; if they are too large, they tend to fall rapidly to the ground instead of coating the intended surfaces, such as plants or insects.

The adhesion of the pesticide is crucial because it determines how well it can control pests. Larger droplets may simply roll off surfaces or fail to cover them adequately, leading to inadequate pest control. This is particularly important when considering factors like wind and surface type, which can also influence how well the pesticide performs.

While smaller droplets have a tendency to drift and evaporate, larger droplets are more likely to be influenced by gravity and therefore do not remain airborne long enough to reach their targets effectively.
