What is a disadvantage of emulsifiable concentrate (EC) and ultra-low volume (ULV) formulations?

Emulsifiable concentrates (EC) and ultra-low volume (ULV) formulations are widely used in pesticide applications due to their effectiveness and ease of use. However, one significant disadvantage of these formulations is that the solvents used may cause rubber or plastic components to deteriorate. This can lead to equipment breakdown or failure, which can affect application efficiency and safety.

Many emulsifiable concentrates are composed of organic solvents that enhance the solubility and efficacy of the active ingredients. Unfortunately, these solvents can be corrosive to certain materials, such as those found in hoses, seals, and gaskets of application equipment. If the components are damaged, it can result in leaks or malfunctions during pesticide application, posing risks to the applicator, the environment, and the effectiveness of the pesticide treatment.

Other potential disadvantages, such as high active ingredient concentration and increased volatility, do exist but are not universally problematic across all situations or equipment. Additionally, while higher mixing times may be a consideration for some formulations, it is generally less significant compared to the risks associated with solvent deterioration to equipment.
