Virginia Commercial Pesticide Applicators CORE Exam

What is one major disadvantage of concentrate solution (C, LC, or WSC/WSL) formulations?

1. Very economical

2. Can easily be absorbed through skin

3. High convenience

4. Uniform particle size

The correct answer is: Can easily be absorbed through skin

One major disadvantage of concentrate solutions, such as concentrated emulsions (C), liquid concentrates (LC), or wetting solutions (WSC/WSL), is that they can easily be absorbed through the skin. This characteristic poses significant health risks for applicators and anyone handling these products, as they can lead to systemic exposure to potentially harmful chemicals. Because these formulations are potent and concentrated, the risk of dermal absorption increases, necessitating stringent safety measures, such as using appropriate personal protective equipment (PPE) to minimize skin contact. The other options describe features that are beneficial rather than disadvantages. For instance, being economical highlights the cost-effectiveness of concentrate solutions, while high convenience refers to the ease of use when mixing these formulations. Uniform particle size is a desirable characteristic that typically ensures even distribution and effectiveness when applied.
