What regulates nurseries and garden stores from selling noxious weeds?

The regulation preventing nurseries and garden stores from selling noxious weeds falls under the authority of Quarantine Law RCW 17.24. This law is specifically designed to manage and control the spread of harmful plants, pests, and diseases, which includes prohibiting the sale of certain noxious weeds that can threaten local ecosystems, agricultural practices, and native species. By enforcing quarantine measures, this law helps protect Washington's agricultural interests and environmental health.

In contrast, the Seed Law RCW 15.49 primarily concerns the regulation of seed quality and labeling, rather than the prohibition of specific plants like noxious weeds. The Disease Control Act focuses on the management of plant diseases rather than on the sale of plants themselves. The Environmental Protection Act addresses a broad range of environmental issues and regulations but does not specifically target the sale of noxious weeds in nurseries and garden stores. Therefore, the specificity of the Quarantine Law RCW 17.24 makes it the correct legal framework for regulating the sale of noxious weeds.
