A pesticide with a low LD50 value is considered to be what?

• A. Non-toxic
• B. Moderately toxic
• C. Highly toxic
• D. Environmentally safe

Answer: (C)

A pesticide with a low LD50 value indicates that it requires only a small dose to be lethal to 50% of a test population, usually measured in milligrams of substance per kilogram of body weight. Thus, the lower the LD50 value, the more toxic the substance is considered to be. This measurement is critical in evaluating the potential dangers of pesticides not just to pests, but also to humans and non-target organisms. As such, substances with low LD50 values necessitate careful handling, application, and awareness of safety protocols to minimize risk. This understanding is fundamental for anyone working in pest control or related fields, as it emphasizes the importance of using caution with highly toxic substances.
