Additives that are available to increase surface tension and viscosity can also:

Choosing the option that "All of the above" is the most comprehensive answer, as additives that increase surface tension and viscosity can indeed provide multiple benefits in aerial application of pesticides.

When additives increase surface tension, the resulting liquid exhibits less tendency to spread out and form smaller droplets. This is important in reducing evaporation rates because larger droplets are less quickly evaporated than smaller droplets, contributing to better efficacy and reduced waste of the product.

In terms of minimizing drift, a higher viscosity also contributes to the formation of larger droplets, which are less susceptible to being carried away by wind during application. This minimizes the risk of the pesticide affecting non-target areas, enhancing target precision.

Finally, increasing viscosity can actually help maintain the number of medium to larger droplets produced during spraying, which can lead to better coverage and prevent the situation where only a high number of small droplets form.

By combining all these effects, using such additives allows for a more controlled, efficient, and effective aerial application of pesticides, which is crucial for successful pest management strategies in agriculture.
