What is the proper way to dispose of surplus concentrated pesticide that is still in its original container?

The proper disposal of surplus concentrated pesticides involves ensuring safety and adherence to regulations. Returning unopened pesticides to the manufacturer or distributor is a responsible and recommended practice. This helps prevent environmental contamination while allowing the producer to manage their product properly.

Additionally, giving the surplus to another certified applicator for legitimate use is also acceptable, provided that the receiving applicator has the necessary training and certification to handle such materials. This option promotes the efficient use of pesticides and reduces waste.

While taking pesticides to a landfill may seem like a straightforward disposal method, it is not typically approved due to the potential risks posed by toxic substances leaching into the environment. Hence, the safe and regulated methods of disposal, which include returning products to the manufacturer or redistributing them to trained personnel, are the preferred approaches.
