What is indicated by a pesticide that falls in toxicity Category I?

A pesticide categorized as Category I indicates that it is highly toxic. This categorization is part of a classification system used to help inform handlers and users about the potential dangers of various pesticides based on their acute toxicity. Products in this category usually require specific labeling that highlights the risks associated with their use, including the need for additional protective equipment and precautions to ensure safety during handling and application.

The characteristics of Category I pesticides typically include lower LD50 values (the dose required to kill 50% of a test population) compared to those in higher categories, which reflect increased toxicity. Furthermore, when a pesticide is classified as highly toxic, it signals to users that they should exercise particular care in its use and ensure stringent adherence to safety protocols to minimize any risk of harm to humans, animals, and the environment.
