Which liquid pesticide formulation consists of a small amount of active ingredient dissolved in an organic solvent?

The best answer is emulsifiable concentrate (EC). This formulation consists of a small amount of active ingredient dissolved in an organic solvent. The organic solvent allows the active ingredient to be fully dissolved and effectively mixed. EC formulations can be diluted with water to create an emulsion, making it easy to apply while ensuring thorough coverage of the target area.

Ultra-low volume (ULV) formulations typically contain a higher concentration of active ingredients and are designed to be used in small volumes, often for fogging or aerial applications. Flowables and liquids (F/L) are formulations that are typically more viscous and can contain solid particles suspended in a liquid, rather than solely dissolved active ingredients. Ready-to-use low-concentrate solutions (RTU) are pre-mixed and designed for immediate application, often containing more than just the active ingredient dissolved in a solvent.
