What is a Concentrated Emulsion (EW)?

• A. Is a dry granule requiring dissolution
• B. Has no need for dilution
• C. Consists of thick water based emulsion and an AI paste
• D. Forms milky final spray immediately

Answer: (C)

EW is a concentrated pesticide formulation designed to be diluted with water before use. It typically consists of a thick water-based emulsion in which the active ingredient is present as a paste, helping to keep the AI evenly distributed and to form a stable emulsion once water is added. This structure explains why the option describing a thick water-based emulsion with an AI paste best captures what a concentrated emulsion is. It isn’t a dry granule that you dissolve, and it does require dilution with water. The milky appearance of the final spray comes from the dilution process, not from the concentrate itself before mixing.
