Seed Rules

The proposed amendments add Palmer Amaranth as a prohibited noxious weed seed, clarify that no presence of prohibited noxious weed seed is allowable in seed, move quackgrass from the prohibited noxious weed seed list to the restricted noxious weed seed list, and lower the maximum allowable presence of restricted noxious weed seeds. The proposed amendments also update references, scientific names, and testing processes. These changes will help protect South Dakota by limiting problematic weed seeds in seed mixes and update administrative rules to match industry standards and practices.

New content is added below as the draft rules move through the rule-making process.
