What is one disadvantage of using emulsifiable concentrates (EC)?

The correct answer highlights that one notable disadvantage of using emulsifiable concentrates (EC) is their potential for flammability and phytotoxicity. Emulsifiable concentrates are liquid formulations that contain a high concentration of active pesticide ingredients dissolved in a solvent. While their high concentration can make them effective, it also means that they often contain solvents that can be flammable.

Additionally, if these products are misapplied or used on sensitive plants, they can cause damage, which is referred to as phytotoxicity. This presents a risk not only during application but also in terms of the safety measures required for handling and storing these products. Understanding this disadvantage is essential for ensuring safe and effective pesticide application practices and for mitigating risks to humans, animals, and the environment.
