Seeds treated with prohibited materials are not allowed. Look to the Organic Materials Review Institute (OMRI) or the Washington State Department of Agriculture (WSDA) lists of allowed materials to find seed treatments that are approved. Our staff will verify compliance of any seed treatments not on the OMRI or WSDA lists for you. Just complete and submit a Material Review Request Form for each seed treatment you want to use.
You can also use MyCCOF: Materials Search to find and add materials approved for use in organic production or to request the review of a material you would like to use.
