Introduction This publication contains information about State labeling requirements and prohibitions of noxious-weed seeds and shows the scientific names and common names according to the law and regulations of the State in which the seed is noxious. It is the responsibility of seed dealers to know the requirements of State laws and the changes in those laws.

Appendix A and B contain cross references of State noxious-weed seed common and scientific names. Over time, the Seed Regulatory and Testing Division (SRTD) has compiled many name variations from individual States that SRTD has incorporated into the appendices. Because of the many variations in common names and the possible synonyms in scientific names, SRTD cannot claim that the names in the appendices exactly match the names as published in each State’s seed law or regulations. It is the responsibility of seed dealers to verify name variations used by each State.

In addition to the noxious-weed seed requirements, the maximum percentage of weed seeds permitted by the State laws is shown where applicable. Note: The Federal Seed Act does not limit the percentage of weed seeds but does require truth in labeling as it pertains to weed seed content.

This publication will only be updated when the SRTD receives official information from the State seed control officials. The State seed control officials should contact the SRTD office as soon as updates or changes are being made to their State noxious-weed seed list.

For updates and corrections, State seed control officials should contact:

For the purpose of interstate commerce, the Federal Seed Act defines "noxious-weed seed" as, in part, "the seeds or bulblets of plants recognized as noxious ... by the law or rules and regulations of the State into which the seed is offered for transportation or transported. or … Puerto Rico, Guam, or District of Columbia … or … by the rules and regulations of the Secretary of Agriculture …"

Section 201(a)(5) of the Federal Seed Act provides, in part: "It shall be unlawful for any person to transport or deliver for transportation in interstate commerce--

(a) Any agricultural seeds or any mixture of agricultural seeds for seeding purposes, unless each container bears a label giving the following information…:

(5) Kinds of noxious-weed seeds and the rate of occurrence of each, which rate shall be expressed in accordance with and shall not exceed the rate allowed for shipment, movement, or sale of such noxious-weed seeds by the law and regulations of the State into which the seed is offered for transportation or transported or in accordance with the rules and regulations of the Secretary of Agriculture, when under the provisions of section 101(a)(9)(A)(iii) [the Secretary] shall determine that weeds other than those designated by mailto:Ernest.Allen@usda.gov http://www.ams.usda.gov/rules-regulations/fsa

State requirements are noxious;"

Section 201.16(b) of the Regulations under the Federal Seed Act provides: "Seeds or bulblets of the following plants shall be considered noxious-weed seeds in agricultural and vegetable seeds transported or delivered for transportation in interstate commerce (including Puerto Rico, Guam, and the District of Columbia). Agricultural or vegetable seed containing seeds or bulblets of these kinds shall not be transported or delivered for transportation in interstate commerce.

Under the Federal Seed Act, only agricultural seeds (including lawn seeds) are subject to State noxious-weed seed requirements. However, the interstate provisions as listed above apply to both agricultural and vegetable seeds, even though vegetable seeds are not required to be labeled as to the presence of noxious-weed seeds.

The U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine Program (USDA APHIS PPQ) and the plant health agencies in each of the 50 states, regulate the shipment of nursery and greenhouse stock to minimize the spread of harmful insects, diseases, and other pests. The Federal & State Quarantine Summaries is designed as a reference tool for nursery stock growers, brokers, purchasers, and others involved in the buying, selling, and interstate transport of nursery and greenhouse plant crops. It outlines the basic quarantine and other plant health requirements of APHIS, all 50 states, and Puerto Rico. This publication is available at www.nationalplantboard.org/laws.

The Association of American Seed Control Officials publishes a website at www.seedcontrol.org that has links to each State's webpage. Most of those State's webpages have links to their state seed law.

Noxious Weeds in Commercial Seed

Food and Agriculture Code Division 18, Chapter 2, California Seed Law Sections 52251 through 52515 regulates "noxious weed" (FAC 5004) seed found in commercial agricultural or vegetable seed. The law allows for the designation of seeds from species of noxious weeds into two categories when present in planting seed; "prohibited noxious weed seed" and "restricted noxious weed seed" (Title 3, CCR 3854 and 3855). There are no tolerance levels for prohibited noxious seeds found in planting seed; however restricted noxious weed seeds are subject to tolerance standards when properly noted on the label of the planting seed container. Rejection and disposition of planting seed shipments, if not based on quarantine action, are based on label requirements for planting seeds.

Prohibited

3 CCR § 3854. Prohibited Noxious Weed Seed. In accordance with Section 52332 of the Food and Agricultural Code, the Director hereby designates the seed or propagule of the following species of plants to be prohibited noxious weed seed within the meaning of Section 52257 of the Food and Agricultural Code:

If the seed is contaminated with seeds on this list, then the lost must be labeled to name the restricted noxious-weed seeds and the rate of occurrence per pound of seed. The State will examine seed lots to confirm if the labeled rate of occurrence is within tolerance of the rate of occurrence found under State examinations. California tolerance for labeled versus State determined rate of occurrence is the same as that used by the USDA under FSA Reg/ Sec. 201.65 for noxious-weed seeds in interstate commerce.

3 CCR § 3855 Restricted Noxious Weed Seed.

Unless listed in CCR Section 3854 as a prohibited weed seed, all seeds from plant species listed in CCR Section 4500 are considered restricted weed seeds for purposes of labeling seed containers offered for sale, planting, or distribution in California.

California Quarantine Noxious Weeds of Plant Species Not Listed in CCR 4500 in Shipments

In addition to the noxious-weed species listed in CCR 4500, the State of California plant quarantine laws also regulate shipments found infested with propagules of weed pests of known economic or environmental detriment and either not known to be established in California or of limited distribution that allow for the possibility of eradication or successful containment. Such shipments may be rejected.

Firms shipping seed into California should obtain a copy of both the California Plant Quarantine Manual and Seed Laws for guidance. These are available from the Pest Exclusion/Seed Service, Plant Health and Pest Prevention Services, California Department of Food and Agriculture, 1220 N Street, Room 344, Sacramento, CA 95814, telephone (916) 654-0435 (www.cdfa.ca.goc/phpps/PE/nsc/index.html) http://www.cdfa.ca.goc/phpps/PE/nsc/index.html
