Which disadvantage is associated with emulsifiable concentrates (EC)?

1. High cost

2. Easily absorbed through skin

3. Does not require agitation

4. Low drift risk

The correct answer is: Easily absorbed through skin

Emulsifiable concentrates (EC) are known to have certain characteristics that can pose risks to applicators. One significant disadvantage is that they can be easily absorbed through the skin. This is primarily due to the solvent and other chemical ingredients used in these formulations, which enhance the product's ability to penetrate skin barriers. As a result, applicators need to take extra precautions, such as wearing appropriate protective equipment, to prevent skin exposure. In contrast, while factors like cost, the need for agitation, and drift risk might be relevant considerations for different classes of pesticides or formulations, they do not directly pertain to the notable risk of skin absorption associated with emulsifiable concentrates. Understanding the unique properties and risks tied to this category helps in ensuring safe handling and application practices.
