Weed Regulatory Services

Non-native invasive plants can cause significant harm to native habitats, agricultural production, recreational activities and even human health. The economic damage caused by non-native invasive plants along with control costs has been estimated over $32 billion annually in the United States. If allowed to spread over large areas, invasive plants become more costly to control and the probability they can be eradicated decreases.

The State Noxious Weed Regulations, adopted under authority of the N. C. Plant Pest Law, were established to prevent the widespread establishment of harmful non-native plants that are placed on the Noxious Weed List. Any plant on the Noxious Weed List is prohibited entry into the state without a permit. Noxious Weeds already present in the state are contained by prohibiting movement of the plant outside of regulated areas. In addition to the plant itself, articles that could contain Noxious Weed propagules such as soil or hay, are also regulated. Regulated areas or quarantine boundaries are usually defined by county boundaries and must be described by no more than 20 counties. In addition, the sale of Noxious Weeds is prohibited unless exempted by provisions of the Noxious Weed Regulations. In addition to the State Noxious Weed Regulations, the General Assembly of North Carolina has adopted the Aquatic Weed Control Act providing the Department of Agriculture with the authority to regulate the importation, sale, use, and distribution of noxious aquatic weeds.

Components of the Regulatory Weed Program include updates of the State Noxious Weed Regulations and the monitoring and treatment of noxious weed infestations including witchweed, orobanche, purple loosestrife, tropical soda apple and mile-a-minute vine.
