What is defined as a noxious weed seed according to FAC 52256?

The definition of a noxious weed seed according to FAC 52256 specifically pertains to the seeds or propagules of defined noxious weed species. Noxious weeds are plants that are considered harmful to agricultural or horticultural crops, natural habitats, or ecosystems, as they can outcompete native plants or crops for resources such as nutrients, water, and light.

The designation of "noxious" is often based on established lists that outline which species are considered harmful and warrant control measures. This means that seeds or propagules from these defined species are regulated to prevent their spread and impact on the environment and farming.

Other choices lack the specificity required to match the legal definition. For example, while invasive species may often overlap with noxious weeds, not all invasive species are classified as noxious according to the criteria set by FAC 52256. A broad categorization like "any garden plant seed" does not accurately define noxious weed seeds, as many garden plants are non-invasive and beneficial. Lastly, restricting the definition to just the seeds of grass species fails to acknowledge that noxious weeds can belong to various plant categories, not just grasses.
