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.
