Residue Studies

DRAFT

The IR-4 Food Crop Residue Program establishes 40 to 50 research projects a year throughout the US and Canada to support domestic crop growers. The placement of these studies are based on EPA regions and where crops are typically grown. There are between 3? and 12? assigned for outdoor field trials and another 4? for greenhouse studies for crops grown under cover, such as tomatoes. After products are applied according to planned use directions, samples of the crops are collected, frozen, and sent to analytical labs to determine the amount, if any, of residues found at the time of harvest. Final results are submitted to EPA which reviews the data and then establishes tolerance levels.

Outcomes

  • Improved options for producing high quality specialty food crops
  • Determination of maximum residue limits (MRLs) to ensure safe food supply
  • Enhanced access to less costly and diverse fruits and vegetables to improve human nutrition
