The South Dakota Department of Agriculture warns people to not plant any unsolicited seeds. The warning is in response to nationwide reports of packages from China containing unsolicited seeds. Interim State Ag Secretary Larry Rhoden says the seeds could contain invasive species, introduce disease to native plants, or be harmful to livestock. Rhoden says state officials are not sure the intent behind the activity, but he says if unsolicited seeds come in the mail, recipients should NOT plant them and should SAVE the seeds and packaging, including the mailing label.
