What would the abbreviation "EC" refer to in pesticide formulations?

The abbreviation "EC" in pesticide formulations refers to "emulsifiable concentrate." This type of formulation is characterized by its ability to mix with water to form an emulsion, which is a stable mixture of two immiscible substances—typically oil and water. Emulsifiable concentrates are often used because they allow for easier application and distribution of active ingredients while minimizing the potential for residue on plants or surfaces.

When mixed with water, the emulsifiable concentrate creates a uniform solution, allowing for effective delivery of the pesticide to the target area. This is particularly beneficial for systemic pesticides or those that require thorough coverage. Furthermore, the emulsifiable concentrate formulations generally have a higher concentration of active ingredients compared to other formulations, such as solutions or suspensions, which makes them efficient in terms of application rates.
