What does the abbreviation EC stand for in pesticide formulation?

1. Aqueous concentrate

2. Emulsifiable concentrate

3. Effective compound

4. End-use concentrate

The correct answer is: Emulsifiable concentrate

The abbreviation EC in pesticide formulation stands for Emulsifiable Concentrate. This formulation type is designed to mix with water to create an emulsion, allowing for an effective way to apply pesticides. Emulsifiable concentrates typically contain active ingredients dissolved in organic solvents along with emulsifiers, which help stabilize the mixture when combined with water. This formulation is particularly useful because it allows for easy handling and mixing while maintaining high concentrations of active ingredients. In contrast, the other options refer to different types of pesticide formulations that are less commonly associated with the abbreviation EC. For instance, an aqueous concentrate would focus more on water-based solutions, while an effective compound may refer to the active ingredient’s overall effectiveness rather than a specific formulation type. End-use concentrate suggests a product ready for application, but it does not specifically align with the traditional designation of EC used in the industry. Thus, Emulsifiable Concentrate is the precise term for EC in pesticide formulation.
