An Emulsifiable Concentrate container typically contains how many pounds of active ingredient per gallon?

• A. 1 pound
• B. 1.5 pounds
• C. 2 pounds
• D. 2.8 pounds

Answer: (D)

Emulsifiable Concentrates are concentrated liquids where a relatively high amount of active ingredient is carried in a solvent with surfactants, designed to be diluted with water before use. Because they are concentrated, the label lists how many pounds of active ingredient are in each gallon of concentrate. In practice, EC products typically run around 2 to 3 pounds of active ingredient per gallon, and 2.8 pounds per gallon is a common, representative figure used in exams and guidelines. This high concentration means the final spray solution, after dilution, will contain the appropriate lower amount of active ingredient per gallon for safe and effective application. Always check the specific product label for the exact concentration, since it can vary.
