Ohio Seed Improvement Association has been designated as the official Noxious Weed Free Forage and Mulch (NWFF&M) Certification Agency in Ohio. Program standards comply with the Regional Weed Free Forage Certification Standards developed by the Weed Free Forage Committee of the North American Invasive Species Management Association (NAISMA). The Weed Free Forage Committee has established minimum standards to allow uniform participation by states and provinces in the program. Forage and mulch certified under the OSIA certification program with proper certification documents or markings attached will be eligible to be shipped into restricted areas in the United States and Canada where only forage and mulch certified under the Regional Forage Certification Standards can be used.
