What do surfactants do in pesticide applications?

  1. Absorb moisture from plants

  2. Enhance the scent of pesticides

  3. Change the color of pesticides

  4. Alter the dispersing, spreading, and wetting properties of spray droplets

The correct answer is: Alter the dispersing, spreading, and wetting properties of spray droplets

Surfactants are added to pesticide applications to improve their effectiveness by altering the dispersing, spreading, and wetting properties of the spray droplets. Option A is incorrect because surfactants do not absorb moisture from plants. Option B is incorrect because surfactants do not enhance the scent of pesticides. Option C is incorrect because surfactants do not change the color of pesticides. The main purpose of surfactants in pesticide applications is to improve the coverage and penetration of the spray, making it more effective in controlling pests.
