The disposal of accumulated agricultural pesticides is an expensive proposition due to the hazardous nature of these materials. States have inititated unwanted pesticide collection efforts based on several funding options.

It may be advantageous to give greater weight to efficiency considerations for the disposal of existing unwanted pesticide stocks, while equity considerations may be emphasized for the disposal of anticipated future stocks.
