Healthy Agriculture through Clean Plants

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.
