Response: The invasion of noxious weeds causes substantial economic loss and ecological damage. Common sources for the introduction and spread of weed seed include the transportation and utilization of contaminated forages.
In Minnesota, the state agency in charge of certified hay is the MN Crop Improvement Association (MCIA). The Noxious Weed Seed Free Forage certification program is designed to assure that forage (hay, cubes and pellets) meets minimum standards designed to limit the spread of noxious weeds. Most public lands in the western U.S. require that hay transported into these areas be certified noxious weed free.
To grow Noxious Weed Seed Free Forage, famers must first submit an application for membership to MCIA and apply for field inspection stating the location of the field and expected harvest date. MCIA then inspects the field and intended storage site to determine conformance to standards for freedom from noxious and undesirable weeds. The farmer then harvests the eligible crop and submits a tag request for the bales harvested. Certification labels are then issued by MCIA for eligible bales. The labels must be attached to each bale prior to delivery.
The MCIA website has additional information at www.mncia.org/, or they can be contacted by phone at 1-800-510-MCIA.
