Safeguarding and supporting specialty crops by providing a sustainable source of clean plant material through innovation, collaboration, translational science and outreach.
Why use clean plants? To increase quality, yield, and profit.
The National Clean Plant Network (NCPN) is comprised of clean plant centers, scientists, educators, state and federal regulators, large and small nurseries, and growers of specialty crops that work together to ensure that plant propagation material is clean and available.
The Network was created to protect U.S. specialty crops such as berries, citrus, fruit trees, grapes, hops, roses and sweetpotatoes from the spread of economically harmful plant pests and diseases. NCPN ensures the global competitiveness of U.S. specialty crop producers by creating high standards for our clean plant programs.
HLB-infected trees become unproductive within 2 to 4 years after the onset of the disease and young trees that become infected typically do not reach a productive age. There is no cure and all types of citrus and cultivars are affected. Read more.
Depending on BIScV strain and blueberry cultivar, symptoms vary from asymptomatic to severe blighting of flowers, young leaves and twig dieback. Plants with severe blighting bear little or no fruit and take on a scorched appearance. Read more.

"The NCPN has really accelerated nurseries clean stock program. It is hard to put a number on the value of access to high-quality virus free material; but I cannot imagine what our industries would like without it! There is certain material we wouldn’t be able to produce at all, and whole sectors of the industry would be at tremendous risk of catastrophe.”
Reid Robinson, Fruit Trees, Sierra Gold, California
“The National Clean Plant Network is important to Double A Vineyards’ future business success...This is not something we could do ourselves and the program is a great example of the industry working together for the benefit of all.”

“Star Roses and Plants has been working with FPS for over 35 years allowing us to ensure our new introductions come from virus indexed material. The funding from NCPN has allowed FPS and the grower community they service to increase their capacity and varieties they offer, guaranteeing the long-term sustainability of a program invaluable to the rose industry.”
