Facilitating the regulatory approval of crop protection tools on food crops continues to be the central objective of the IR-4 Project.
Since 1963, IR-4 stakeholders have submitted thousands of requests for assistance.
How do I Request Assistance?
- Talk with your local Commodity Group, Extension Agent, and/or Regional Field Coordinator
- Submit a Project Request
What Happens Next?
- Attend the Food Use Workshop to make others aware of your need and garner support.
- Trial samples are then sent to Analytical Laboratories at SAES or USDA-ARS Facilities and if necessary contract labs are assigned samples
- The labs determine the amounts of chemical remaining in or on the crop
- IR-4 QAU and EPA inspections and audits are conducted throughout the study
- This data is then compiled into a regulatory package and submitted to the EPA requesting establishment of new tolerances (Maximum Residue Limits or MRLs).
Behind the Scenes
- IR-4 personnel hold many meetings with registrants to determine their level of support of an IR-4 submission.
- IR-4 personnel meet with the EPA to determine the “red, yellow, green” chance for a tolerance to be granted on the particular chemical/s
