What is the primary purpose of a chemical known as a surfactant in a pesticide mixture?

Directed Application
Surfactant
Dispersing Agent
Desiccant

The correct answer is: Surfactant

The primary purpose of a surfactant in a pesticide mixture is to act as an emulsifier, allowing the pesticide to mix with and spread over the surface of the plants more effectively. Option A, directed application, is a technique rather than a purpose of a surfactant. Option C, dispersing agent, is also incorrect as dispersing agents are primarily used to promote uniform distribution of the pesticide within the mixture. Option D, desiccant, is used to dry out and damage pests, but is not a primary purpose of a surfactant in a pesticide mixture. Therefore, the best answer is B.
