Understanding the toxicity of a pesticide is crucial for evaluating its hazard potential. Hazard potential refers to the degree of risk a substance poses to health, safety, and the environment when used according to label instructions. Pesticide toxicity provides insight into how harmful the chemical can be if it comes into contact with humans, animals, or the environment.

Knowing the toxicity helps assess potential risks, such as the likelihood of causing harm under various scenarios, including exposure levels and application methods. This assessment goes beyond mere toxicity values; it involves understanding how those values translate into real-world risks. Therefore, toxicity information is a key component in determining how hazardous a pesticide can be.

Factors such as cost, effectiveness, and environmental impact involve more comprehensive evaluations, which include additional criteria beyond just toxicity. Cost pertains to the financial aspect of purchasing and applying the pesticide. Effectiveness relates to how well the pesticide performs its intended function, such as pest control. Environmental impact encompasses a broader range of considerations, such as persistence in the environment, effects on non-target species, and potential for groundwater contamination, all requiring more than toxicity data to assess adequately.
