Forage that is inspected shall fall under one of two criteria: 

  • MEETS requirements of the NAISMA Minimum Weed Free Forage Standards. This forage may contain variable amounts of Prohibited or Noxious weed species which are immature, (no viable seed) when harvested, or were treated to prevent seed formation. These plant parts, although not usually desirable in the forage product, are not considered able to begin new infestations.                  

  • DOES NOT MEET (Failed) requirements of the NAISMA Weed Free Forage Standards.

This fee will be imposed whether the field passes inspection or not.  For fields that pass inspection the producer may then purchase certified weed free twine or tags at cost.  All bales must have certification tags or designated twine attached to be considered weed free.
  2.   Requests for certification must be made a minimum of 5 days before the field is cut and a maximum of 10 before the field is cut.
