Indiana Pesticide Applicator Core Practice Exam

Which of the following statements is true regarding emulsifiable concentrates?

1. Can cause dermal hazards

2. Do not require agitation

3. Safe for all types of surfaces

4. Have low penetrating power

The correct answer is: Can cause dermal hazards

Emulsifiable concentrates are pesticide formulations that can easily mix with water to form an emulsion. One of the characteristics of these formulations is that they can indeed pose dermal hazards. This is due to the presence of solvents and surfactants within these concentrates, which can enhance skin absorption and increase the potential for skin irritation or chemical burns. It is crucial for applicators to take proper safety precautions, such as wearing appropriate personal protective equipment (PPE), when handling emulsifiable concentrates to minimize the risks associated with dermal exposure. The other options do not accurately reflect the properties of emulsifiable concentrates. They typically require agitation to ensure that the active ingredients remain properly mixed and don’t separate. They are not always safe for all types of surfaces, as they can sometimes cause damage depending on the surface material and the nature of the active ingredient. Additionally, emulsifiable concentrates often have good penetrating power, which makes them effective for treating various target areas but also necessitates careful use to prevent unwanted absorption by non-target plants or surfaces.
