Wyoming Pesticide Applicator Practice Test 2026 – Complete Exam Prep

An invert emulsion refers to a mixture in which water droplets are suspended in an oil base. In this type of emulsion, the water phase is dispersed in the oil phase, leading to a stable emulsion where water droplets are the dispersed phase and the oil acts as the continuous phase. This type of emulsion is commonly used in pesticide formulations to improve the efficacy, stability, and spreading of the active ingredients on the target surface.

Options B, C, and D are incorrect:

- Option B describes an oil-in-water emulsion, which is the opposite of an invert emulsion.

- Option C describes an oil-in-air mixture, which is not relevant to the concept of invert emulsions.

- Option D incorrectly suggests suspending water droplets in a vacuum, which is not how emulsions work.
