OMRI is short for the Organic Materials Review Institute, an international non-profit organization that determines which input products are allowed for use in certified organic operations under the USDA National Organic Program. By focusing solely on input products, OMRI offers expertise that supports the organic certification process.
To be included on the OMRI list, products must be reviewed and verified as having ingredients and formulations that are allowed under the organic standards.
Earth's Ally products that are OMRI Listed® for organic gardening:
- Earth's Ally Weed & Grass Killer Concentrate
- Earth's Ally 3-in-1 Plant Spray
- Earth's Ally Insect Control
- Earth's Ally Disease Control
The review process does not “certify” an input product as organic but recognizes that it has been found to have ingredients that are safe for organic growing, which helps gardeners feel confident that products bearing the OMRI Listed® logo are safe for use and meet USDA requirements.
