What is the function of an adjuvant that improves the spreading, dispersing, and/or wetting properties of a pesticide mixture?

Surfactant
Dispersing Agent
Directed Application
Dormant Spray

The correct answer is: Surfactant

An adjuvant is a substance added to a pesticide formulation to improve its performance. In this case, when an adjuvant is used to improve the spreading, dispersing, and wetting properties of a pesticide mixture, it is specifically referred to as a surfactant. Surfactants work by reducing the surface tension of the spray solution, allowing it to spread more evenly and penetrate plant surfaces more effectively. This helps ensure better coverage and uptake of the pesticide by the target pests or plants.
