Which is a disadvantage of emulsifiable concentrates?

• A. Volatility potential
• B. May be hazardous to applicator
• C. Both are disadvantages
• D. None of the above

Answer: (C)

Emulsifiable concentrates are a solvent-based pesticide formulation where the active ingredient is dissolved in petroleum solvents with emulsifiers to mix with water. This design makes application easy, but it brings two notable downsides. The solvents in ECs are volatile, so vapors can escape during and after application, increasing inhalation risk for the applicator and the chance of off-target movement or drift. At the same time, the concentrated, solvent-rich nature of ECs can be hazardous to the applicator through skin contact, eye exposure, and inhalation if proper PPE and handling procedures aren’t followed. Because both of these conditions are inherent to emulsifiable concentrates, both are considered disadvantages.
