What is the function of a surfactant in pesticide applications?

The function of a surfactant in pesticide applications is to enhance the effectiveness of the pesticide by improving adherence and spread. Surfactants lower the surface tension of water, allowing the pesticide to spread more uniformly over the plant surface, which ensures better coverage of the target area. This improved coverage helps the active ingredient penetrate plant surfaces more efficiently, increasing the likelihood of effective pest control.

Additionally, by improving adherence, surfactants help the pesticide remain on the surface longer, reducing the chance of runoff and enhancing absorption. Ultimately, when the effectiveness of the pesticide is maximized through the use of surfactants, it can lead to better pest management outcomes while potentially reducing the amount of pesticide required.
