What is true of a product's EPA registration?

The statement that it is against federal law to use the product contrary to the label is valid because an EPA registration ensures that the product has undergone a thorough review process to assess its safety and efficacy for specific uses. This registration is legally binding, meaning that users are required to follow the instructions and guidelines provided on the label to ensure safe handling and application.

The law exists to protect consumers, workers, and the environment by preventing misuse that could result from using the product in a way not evaluated or approved by the EPA. Using a product contrary to its label can lead to legal repercussions and is considered a violation of federal regulations. Thus, adherence to label instructions is essential in maintaining safety standards and compliance with the law.
