CPDA Adjuvant Certification

The CPDA voluntary Adjuvant Certification Program is the first of its kind.  Since its launch in 2001, it has quickly gained industry recognition as an innovative tool for encouraging product stewardship in the manufacture of agricultural adjuvants.  Prior to this program, end users had little, if any, scientifically accepted standards by which they could effectively judge the quality of a tank-mix adjuvant.  Members of the CPDA Adjuvants and Inerts Committee developed the program to bring a level of consistency in product performance for adjuvants used with agricultural pesticide formulations.  Products certified under the program must meet 17 separate benchmarks that are based on technologically and scientifically derived definitions and standards adopted by the American Society for Testing and Materials, now known as ASTM International, and certain requirements of the U.S. Environmental Protection Agency (EPA), the U.S. Department of Transportation, and the U.S. Occupational Safety and Health Administration.  Agricultural spray adjuvants are not subject to federal regulation by EPA.

CPDA Adjuvant Certification Testing Requirements

To apply for CPDA adjuvant certification you must have at least basic toxicology data.  For non toxic adjuvants this includes 3 basic acute tests.

If your product has shown toxicity, additional testing may be required.  This may include

  • Acute Inhalation Toxicity (OCSPP 870.1300)
  • Acute Dermal Corrosion/Irritation (OCSPP 870.2500)

If your product will be labeled for aquatic applications, additional aquatic toxicology testing will be required.  These could include but are not limited to

We can provide all these studies in house at our main facilities in Sugar Land.

STILLMEADOW has been providing this same testing for EPA submission for over 45 years.  You can trust us to complete you data requirements for your important product submission.
