Which of the following is a disadvantage of emulsifiable concentrates (EC)?

Emulsifiable concentrates (EC) are a popular formulation in pest control due to their effectiveness and ease of application. However, one notable disadvantage is that they can be absorbed through the skin. This characteristic raises concerns regarding safety for the applicator and anyone who may come into contact with the pesticide during handling and application. The potential for skin absorption means that protective gear, such as gloves and long sleeves, is essential to minimize health risks when handling these concentrates.

The other options present advantages or neutral characteristics of emulsifiable concentrates. For instance, the fact that they are non-toxic to humans and animals is generally viewed as a positive trait, as safety is a priority in pest management. The nature of emulsifiable concentrates also allows them not to separate during application, which contributes to their effectiveness, making their application uniform and efficient. Finally, their cost-effective nature typically makes them an attractive choice in pest control strategies. Understanding these aspects helps users recognize both the benefits and the precautions necessary when working with EC formulations.
