Noxious Weed Free Forage & Mulch FAQ
Who is the designated authority of NWFF&M in Ohio?
The Ohio Seed Improvement Association (OSIA) is the only official designated authority to perform the NWFF&M Certification program in Ohio. OSIA is authorized to perform this function by way of a memorandum of agreement with the North American Invasive Species Management Association (NAISMA). Only mulch products produced by OSIA members, passing Certification, and properly identified are legally termed “Certified.”
What are the benefits of Certified Mulch Products?
Where can I find Ohio sources of NWFF&M Products?
OSIA publishes an Annual Directory listing the contact information for all current year’s NWFF&M participants. Other regional crop improvement agencies are also potential sources for Certified NWFF&M products.
What products can be certified as noxious weed free?
The most common Certified mulch is straw derived from small grain fields such as wheat, rye, oat, spelt, barley or special crop mixtures. Grass or legume hay, cubes and pelleted forage products are also eligible for certification.
