1. Emulsifiable concentrate

2. Flowable

3. Low volatile

4. Gel

The correct answer is: Emulsifiable concentrate

The abbreviation "EC" in pesticide formulations stands for "Emulsifiable Concentrate." This formulation type is designed to mix with water to create an emulsion, which is a stable mixture of two immiscible liquids (like oil and water). Emulsifiable concentrates typically contain active ingredients dissolved in an organic solvent, which allows for high concentration of the pesticide in a relatively small volume. This formulation is beneficial for many applications because it allows for easy handling and diluting with water to achieve the desired concentration for effective pest control. The emulsifying agents in the formulation ensure that the active ingredient is evenly distributed in the water when mixed, preventing separation and allowing for consistent application. Understanding the characteristics of emulsifiable concentrates is important for pesticide applicators, as it affects how they mix, handle, and apply these products while ensuring that they are following safety guidelines and maximizing efficacy.
