• The National Clean Plant Network-Citrus (NCPN-Citrus) was established in 2010 and is part of the National Clean Plant Network (NCPN), which is concerned with the health of vegetatively propagated specialty crops.

• NCPN-Citrus will ensure the high quality (true-to-type) citrus propagative materials are produced (therapy & diagnostics), maintained (management & retesting of foundation blocks & nursery sources), and distributed throughout the USA under the standards of excellence established by the NCPN governance.

To prevent the spread of these potentially devastating diseases, a source of clean or pathogen-tested budwood for citrus tree propagation is essential.
