Clean Plant Centers
The NCPN is a group that strives to keep specialty crops free of diseases.
Sweet potatoes are a new addition to the network, which provides land-grant universities funding through the U.S. Department of Agriculture to develop and evaluate virus testing procedures and make high-quality planting stocks available to the industry.
Production of sweetpotato crops starts with clean plant material. Healthy plants are easier to propagate and produce higher yields and better quality sweetpotatoes.

The National Clean Plant Network for Sweetpotato is an association of clean plant centers, scientists, educators, state and federal regulators, certified seed growers, and commercial growers from the fresh market and processing industries concerned with the health of planting stock (seed roots and vine cuttings). The NCPN operates under the auspices of three agencies within the United States Department of Agriculture - Animal and Plant Health Inspection Service (APHIS), Agricultural Research Service (ARS) and National Institute of Food and Agriculture (NIFA).
