About Us



There is a growing demand in North America for the use of certified noxious weed free forage and straw as a preventive program to limit the spread of noxious weeds. This voluntary inspection program is designed to assure that forage and straw sold with proper inspection identification meets minimum standards designed to limit the spread of noxious weeds. Buyers are provided assurance that forage and straw, inspected through this program, meet these minimum standards.

These inspection standards comply with and in some cases exceed the North America Weed Free Forage Certification Standards developed by the Regional Weed Free Committee of the North American Weed Management Association. The North America Weed Free Forage Committee has established minimum standards to allow uniform participation by states and provinces in the program. Forage and straw inspection under the program with proper markings attached will be eligible to be shipped into restricted areas where only forage and straw inspected under the North America Weed Free Forage Certification Standards can be used.

The various inspections that are an integral part of this program minimize the opportunity for misleading or fraudulent actions on the part of the applicants participating in the program. However, the production and distribution of inspected material depends on the integrity of those participating in the program.

It is the responsibility of every member of the Wallowa County Weed Free Forage Inspection Program to abide by the rules, adhere to the standards, and report irregularities or violations.


Applicants desiring to have their forage and/or straw inspected must apply to the Wallowa County Inspection Program on an application form supplied by the County. Forms are available upon request from:

Wallowa County Extension Services
668 NW First
Enterprise, Oregon 97828

Applications must be received ten (10) working days prior to cutting. Late applications may result in the field inspection not being made.
A Afield@ is defined as the area occupied by one crop, covered by one inspection report and not divided by streams, public roads, other crops, or other barriers that materially increase the difficulty of inspection. If the inspected forage or straw field is also being inspected for certified seed production, indicate the corresponding seed production field number(s) on the application form.


To be eligible for forage or straw inspection, fields must be inspected by the County Weed Free Forage Inspector before harvest. A crop that is harvested prior to inspection is not eligible for certification. It is the applicant=s responsibility to ensure that the crop has been inspected before harvest.

Field inspection is a thorough examination of the forage or straw production site to confirm compliance with the inspection standards. The inspector will make a visual inspection of the field and entire field border. County inspection procedures will follow the guidelines established by the North America Weed Free Forage Standards. Any condition(s) which are apt to make inspection inaccurate or bring the certification process into disfavor, shall be cause for rejection.


Forage and straw shall be free of those noxious weeds and undesirable plant species identified in Appendix A.

1. In Wallowa County, forage and straw fields shall be inspected by the County Weed Free Forage Inspector.
2. Forage and straw shall be inspected in the field of origin. The field shall include the surrounding ditches, fence rows, roads, easements, grass waterways, or a buffer zone surrounding the field.
3. The field must be inspected by County Inspector prior to cutting or harvesting.
4. Forage which contains any noxious weeds, or undesirable plant species, as identified in Appendix A, may be certified if the following requirements are met:

a) Field upon which the forage was produced was treated to prevent seed formation or seed ripening to the degree that there is no danger of dissemination of the seed, or any injurious portion thereof from such noxious weeds, or undesirable plant species, or the propagating parts of the plant are not capable of producing a new plant.
2) Noxious weed(s) or undesirable plant species was treated not later than rosette to bud stage, or boot stage for perennial grass species classified as weeds, prior to cutting or harvesting.
3) Treatment method can include but is not limited to: 1) burning, 2) mowing, cutting or rouging, 3) mechanical methods, or 4) chemicals.

5. An A Inspection Certificate@ shall be issued by Wallowa County indicating that the above requirements have been met based upon field inspection.


The applicant must keep accurate records of the amount of forage or straw harvested from each field including where the forage or straw is stored after harvest. The following records must be maintained:
1. The number and average weight of bales harvested;
2. The exact location where bales are stored;
3. Date of harvest;
4. Field number and location of the field where the product was produced;
5. Copies of all certification documents; and

Noxious Weed Free Forage and Straw
Field Inspection Procedures


The purpose of the Noxious Weed Free Forage and Straw (NWFF&S) certification program is to prevent the spread of noxious weeds. Wallowa County standards meet or exceed standards developed by the Regional Weed Free Forage Committee of the North American Weed Management Association. These standards were established to assure uniformity between states and provinces in the development and implementation of individual noxious weed free forage and straw programs. The Regional Weed Free Forage committee has established a list of noxious weed seeds and propagating materials that are not permitted in any material that is to be entered into the program. NOTE: See Appendix A. In addition to these weeds Wallowa County is including the following:

Night flowering catch fly Silene noctiflora
White campion Silene alba
Redroot Pigweed Amaranthus retroflexus
Jim Hill Mustard Sisymbrium altissimum
Tansymustard, pinnate Descurainia pinnata
Netseed lambsquarter Chenopodium berlandieri
Shepard’s-purse Capsella bursa-pastoris
Field pennycress Thlaspi arvense
Prickly lettuce Lactuca serriola
Fiddleneck tarweed Amsinckia intermedia
Common mallow Malva neglecta
Common mullein Verbascum thapsus
Common teasal Dipsacus fullomum
Black nightshade Solanum nigrum
Hairy nightshade Soanum sarrachoidees
Catchweed bedstraw Galium aparine
Green Foxtail Setaria viridis
Smartweed (sp) Polygonaceae
Curly dock Rumex crispus
Western salsify Tragopogon dubius
Wild buckwheat Polygonum convolvulus
Kochia Kochia scoparia
Barnyardgrass Echinochloa crus-galli


As field inspectors, it is required that you read and understand the specific standards and inspection procedures for this program. An inspection training session will be required each year.


Field inspection applications for noxious weed free forage and straw fields will be assigned to the field inspector by the field supervisor at the earliest possible date. It is the responsibility of the field inspector to complete the field inspection before harvest. It is the responsibility of the applicant to notify Wallowa county if they are ready to harvest and the field has not been inspected. Any field not inspected before harvest will be ineligible for the program.


Inspections of NWFF&S fields consist of identifying noxious weeds in the field and adjacent
areas of the fields such as other fields, road ditches, fence rows, waterways, rock or brush piles or other areas. All inspections for this program must be accurate and thorough.


For materials to be eligible for the NWFF&S certification program, all field inspections must take place prior to harvest. It is recommended that all forage fields be inspected within ten (10) days of harvest. Fields in which straw will be harvested can be inspected two weeks prior to harvest or when more appropriate prior to baling. If other corrections need to be made this will allow the applicant time to make the correction prior to re-inspection.

The procedures used for walking NWFF&S fields are different from those methods used for walking fields for certified seed inspection. There shall be a minimum of two entry points per field. There shall be a minimum of one entry point per each 10 acres. Each point of entry shall be at least 150 feet into the field, and each additional 150 feet traveled shall constitute an entry point. Travel shall be uninterrupted, proceeding through the field being inspected. The entire field border shall be walked or driven. Fields shall be inspected within 10 days prior to harvest. An inspector may not inspect fields of which said inspector has ownership or financial interest. If there is a heavy infestation of weeds other than those on the noxious weed list, the inspector should make note of it in the comment section of the inspection certificate.


If any noxious weeds are found in the field during the field inspection, the field must be rejected. The field may be re-inspected at a later date, however in order for the field to pass a second inspection, the applicant must make the necessary correction to eliminate the cause for rejection. NOTE: If fields being inspected for the NWFF&S program are also being inspected for certified seed, field reports must be completed and field status must be determined for each individual program. A field may meet the criteria of one program but not another.

1. No noxious weeds on Wallowa County’s “A” list

2. No weeds on NAWMA list with reproductive parts.

3. No weeds found on NAWMA list that would cause quality impairment

4. No undesirable plants in a form to cause quality impairments.
Grades of Wallowa County weed free forage

Premium grade —meets all 4 criteria above
Reclamation Grade — meets criteria 1 & 2 above


Options are to cut, mow or avoid the infested areas at harvest time. If the area has been cut, mowed or avoided at harvest time, the areas must also be left undisturbed so the inspector can verify, during the re-inspection, that the infested areas were not harvested.


Areas adjacent to fields inspected under the NWFF&S certification program are required to be free of noxious weeds. Adjacent areas include: other fields, road ditches, waterways, fence lines, rock or brush piles or any other areas that may serve as a source of noxious weed contamination. When adjacent areas contain noxious weeds, a 10-foot buffer zone must be established by mowing, cutting, cultivating or spraying between the production field and the noxious weed infested area. Any borders not maintained in accordance with the standards at the time of field inspection must be rejected. The applicant will have the opportunity to make the border correction. A re-inspection will be required and additional fees paid.


If the field is rejected due to non-maintenance of adjacent areas, the applicant has the option of establishing a buffer zone to separate the field to be harvested from the source of noxious weed infestation. This buffer zone must be a minimum of 10-feet wide and may be established by mowing, cutting, cultivating or spraying. The buffer zone must be established in a manner that allows the inspector to check the area at the time of re-inspection to verify that no material from the buffer zone was harvested as certified material. It is recommended that 2 rows be cut before inspection (this is not required but will speed the inspection process and aid in assuring proper borders are maintained.)

The storage area is to be a weed free environment or the producer must not include the bottom bales when shipping.


The Wallowa County Hay/Straw inspection program expressly represents that it has acted in accordance with those standards and procedures established for hay/straw inspection in Wallowa County. The issuance of an inspection certificate neither warrants that any other person or entity has acted in accordance with such standards and procedures, nor constitutes any other warranty, express or implied including merchantability or fitness for purpose or otherwise which extends beyond that the certification that the product inspected met the regulations of the program.
