What is the role of surfactants in pesticide applications?

To serve as a primary killing agent against pests.
To alter the dispersing, spreading, and/or wetting properties of spray droplets.
To decrease the surface tension of water used in the mix.
To eradicate weeds without harming the crops.

The correct answer is: To alter the dispersing, spreading, and/or wetting properties of spray droplets.

Surfactants play an essential role in pesticide applications by altering the properties of spray droplets. They can improve the contact and penetration of pesticides on plant surfaces, increasing their effectiveness. Option A is incorrect because surfactants are not meant to directly kill pests, but rather to assist in the application process. Option C is also incorrect because while surfactants do decrease the surface tension of water, it is not their primary purpose in pesticide applications. Option D is also incorrect because surfactants do not specifically target weeds, but rather assist in the overall application of pesticides.
