• Noxious Weed Information

    NM green crops and water ditches

    Invasive species have been cited as the second largest threat to endangered native species.  Most noxious species in New Mexico are found on rangelands and wild lands.  Invasions of noxious species in the range and wild landscape result in decreases in available forage for livestock and wildlife.  The Noxious Weeds Management Act directs NMDA to develop a noxious weed list for the state, identify methods of control for designated species, and educate the public about noxious weeds.  NMDA coordinates weed management among local, state, and federal land managers as well as private land owners.

    New Mexico’s Cooperative Weed Management Areas

    CWMAs are a partnership of federal, state, and local government agencies, tribes, individuals, and various interested groups cooperating to manage noxious weeds or invasive plants in their area.  Many CWMAs provide technical assistance, equipment, and educational oppurtunities related to noxious weed identification and management.  They are an important resource in New Mexico’s efforts to manage noxious weeds.

    The New Mexico Seed Law was enacted to serve as a basic “truth-in-labeling” law designed to provide consumers with important information relating to product quality and identity.

    The New Mexico Seed Law regulates both agricultural and vegetable seeds sold in the state. “Agricultural” seeds are those of legumes, grasses, forages, cereals, and fiber crops. Included in this category are lawn and turf seeds. “Vegetable” seeds are those of crops grown commercially and in home gardens and are commonly known as vegetables. Seeds grown strictly for their ornamental value (flower seeds, for example) are not included.

    The law requires all seeds to be labeled truthfully regarding their identification, purity, and viability. Basic quality information relating to germination and weed seed contamination are required to provide the purchaser important information to make intelligent purchases. The law also classifies certain weed seeds as “noxious weeds” and restricts their presence in seed offered for seeding purposes.

    The inspection staff of the Feed, Seed, & Fertilizer group provides marketplace surveillance throughout the state through inspections of retail sales outlets and seed distributors selling seed products. These products routinely consist of various agricultural crop seeds, forage seeds, lawn seeds and vegetable seeds. Samples are obtained through official sampling methods and are analyzed in the State Seed Laboratory to determine compliance with labeled guarantees.

    Example of an agricultural seed tag:

    Kind: Variety: Lot Number:
    Pure Seed:
    Hard or Dormant Seed: (If present)
    Weed Seed:
    Inert Matter:
    Other Crop:
    Noxious Weed Seeds: (Name and Number Per Pound if present)
    Origin:(State or Foreign Country) Test and/or Sell By Date:(Month & Year)
    For Hybrid Corn: Relative Maturity: (Listed in a single day increment such as 93 days)
    Labeler’s Name:


    Test Date, Sell By Date

    • A “Test Date” for agricultural seed means the tag information is only good for nine months and the nine month period does not include the month it was tested.
    • A “Test Date” for lawn and turfgrass seed and native grass and forb seeds when used as agricultural seed is only good for nine months and the nine month period does not include the month it was tested.
    • A “Sell By Date” is the last month and year that a “Test Date” is valid for and may be listed in addition to or in place of the “Test Date.”
    • Seed must be retested and retagged when the “Test Date” period has ended.
  • Plant Inspection, Certification and Quarantines

    All locations that sell plant material are subject to inspection. Inspectors check that plants are healthy and look for pests, including insects, diseases and weeds. They verify that plants brought into New Mexico from other states are in compliance with various quarantines and are certified appropriately by their state of origin. Similarly, they certify plants grown in New Mexico for export to other states, assuring the destination states that New Mexico plant materials are also pest-free.

    Phytosanitary/Origin Certification

    You may need a state or federal Phytosanitary Certificate or a Certificate of Origin, depending on the destination and type of shipment. Prior to issuing the certificate, NMDA must receive a completed Application for Phytosanitary and Certificate of Origin. An inspector will then check the plants or plant products to verify that they are pest-free. There is a nominal charge for the inspector’s travel and time to perform this type of inspection, as well as a small fee for the certificate itself.


    Japanese Beetle Exterior Quarantine –  Infested nursery stock and grass sod are one of the primary ways this pest moves into areas where it does not already exist. This quarantine helps prevent Japanese beetles from becoming established in New Mexico. See also the National Plant Board’s Japanese Beetle Harmonization Plan.

    Cotton Boll Weevil Quarantine – There are restrictions on the movement of most raw cotton products, and the machinery associated with growing and harvesting cotton, from areas that have not “functionally eradicated” cotton boll weevil.

    Pecan Weevil Exterior Quarantine – Pecan trees in soil from the southeastern US, including east Texas, cannot be shipped into New Mexico. All other pecan trees must be accompanied by a certificate of origin or treatment.

    Pepper Weevil Interior Quarantine and Plowdown –  Pepper fields in the regulated area must be plowed down every year by February 1 to reduce overwintering populations of pepper weevil, and residues from pepper processing plants cannot be transported out of the regulated area.

    Pink Bollworm Permanent Plowdown – All cotton plants in New Mexico must be plowed and buried by February 1 of each year to reduce overwintering populations of pink bollworm.

    Red Imported Fire Ant Interior Quarantine  – Within New Mexico the county of Dona Ana is quarantined to prevent the spread of imported fire ants.  Shipments of nursery stock, sod, soil, baled hay and straw, and soil moving equipment originating in Dona Ana County must be certified to be free of the pest. In the case of nursery stock, this is verified by the presence of a shield-shaped stamp from USDA on boxes and/or shipping documents which accompany these items.

    Imported Fire Ant – A USDA shield-shaped stamp with the abbreviation of the originating state in the center must be present on each box or on the shipping documents. This indicates that the plants have been treated to control imported fire ants. It must be included with shipments from the southeastern portion of the U.S., including southeast Texas, as well as Orange County and portions of Riverside and Los Angeles Counties in California.

    Phytophthora ramorum (Sudden Oak Death) – Nurseries in regulated areas in California, Oregon, and Washington that ship host or associated plant nursery stock must have paperwork which carries a Federal shield to prove that they are not infested with this disease.

    Federal Noxious Weeds – Plants listed under this regulation cannot be shipped into New Mexico without an NMDA-approved permit.
