The University has several researchers who use experimental pesticides in their work. These experimental pesticides are only problematic as hazardous waste if the producer of the pesticide will not provide enough information about the formulation to allow proper categorization for disposal. In this situation, the Chemical Waste Program must test the pesticide and dispose of it as if it were an unknown. This is costly and also gives rise to some safety issues since the true hazards of the material are not fully known for handling and packaging purposes.

If you have any concerns regarding the stability of a chemical you wish to test, contact the Chemical Waste Program at (612) 626-6002 prior to testing.


When planning to accept experimental pesticides for a research project, request that the producer agree to accept any residuals once the project is completed. The researcher should return the residuals in a timely manner.

If the producer will not accept the residuals, request the active ingredient and carrier information which would facilitate disposal. With this information, the waste may be prepared for disposal following normal procedures.

If the producer has not agreed to accept the residuals or provide adequate information about the pesticide, the material will need to be processed as an unknown. Call the our office at 726-6764 for assistance.
