What is the recommended action for disposing of unopened surplus concentrated pesticide?

The recommended action for disposing of unopened surplus concentrated pesticide is to return it to the manufacturer or give it to another certified applicator. This option is correct because it adheres to environmental safety guidelines and legal regulations regarding hazardous waste disposal. Many pesticides are toxic and can pose risks to human health and the environment if not disposed of properly. Returning the unused product to the manufacturer allows for proper handling and recycling or re-use, minimizing the risk of pollution.

Giving it to another certified applicator ensures that the pesticide will be used appropriately and responsibly, rather than discarded in a manner that could lead to contamination or harm. Both of these actions promote safe pesticide management and help maintain compliance with state and federal regulations.

The other options involve improper disposal methods that could lead to legal consequences and environmental damage. For instance, disregarding legal requirements can lead to significant penalties, while discarding pesticides in regular trash can expose waste workers and the public to harmful substances. Dumping it in a body of water is illegal and dangerous, as it would lead to significant ecological harm and contamination.
