Emulssifiable Concentrates (EC):

• Emulation is a two phase dispersion involving water and an immiscible solvent i.e. an insecticide is dissolved in an organic solvent to which emulsifiers are added.
• This formulation is generally preferred to WP because the liquid form is more easily handled and mixed in the water.
• Further, presence of oil in the emulsion makes it more toxic and leaves a more persistent deposit than that of suspension.
• It also requires less agitation and thus, are more satisfactory for use by small sprayers.

Advantage

• Price per unit is low
• It is easy to transport and stored
• It treats foliage effectively

Disadvantage

• It is difficult to measure
• There is risk of the applicators skin being contaminated by toxicant.
