About the NCPN
Diseases of vegetatively propagated crops that are caused by viruses and virus-like agents can cause severe damage and economic losses to growers. Diseases are often difficult to detect in propagation material, and can inadvertently be brought to a field where they weren’t present before. Once these diseases are established, they are incurable, and it is very difficult to prevent them from spreading. The best and primary tool for avoiding these diseases is prevention by using clean propagation materials.
The National Clean Plant Network (NCPN) brings together industry leaders, researchers, state regulators and clean plant centers to produce and distribute healthy propagation material in the United States. It began in 2008 with fruit trees and grapes networks and now includes seven specialty crop networks - berries, citrus, fruit trees, grapes, hops, roses and sweetpotatoes. The National Clean Plant Network is partly funded by the United States Department of Agriculture (USDA).
​
NCPN clean plant centers throughout the Network focus on:
-
Diagnostic and pathogen elimination services
-
Production of clean propagative plant material
-
Maintenance of foundation blocks of pathogen-tested plant materials
​







Mission
​
Healthy Agriculture
through Clean Plants
Vision
​
Safeguarding and supporting specialty crops by providing a sustainable source of clean plant material through innovation, collaboration, translational science and outreach.
Purpose
​
To establish a network of Clean Plant Centers for diagnostic and pathogen elimination services to produce clean propagative plant material and to maintain blocks of pathogen-tested plant material in sites located throughout the United States.


Clean plant material is available to states for state certification programs and to private nurseries and producers.
​
NCPN funding has supported 23 clean plant centers plus supporting initiatives.
