What is the signal word for a pesticide with an LD50 of 500-5000 mg/kg?

The signal word for a pesticide with an LD50 of 500-5000 mg/kg is "Caution." This classification indicates the level of toxicity associated with the pesticide. The LD50 (lethal dose for 50% of the population) is a benchmark used to assess the potential hazard of a substance. For pesticides, a higher LD50 number generally signifies lower toxicity.

In this case, an LD50 within the range of 500-5000 mg/kg means that the pesticide can pose a moderate level of risk, requiring an appropriate caution in handling and usage. The signal word "Caution" is utilized to signify that the pesticide should be used with care but is not as hazardous as those labeled with "Warning" or "Danger," which apply to more toxic substances. Therefore, the use of "Caution" alerts users to be mindful while using the product, ensuring they implement the necessary safety protocols while acknowledging its potential risks.
