What We Do

The NCPN-Citrus clean plant centers ensure that citrus trees produced in the USA are propagated using HLB-free propagative materials. Such materials are produced under highly specialized therapy and diagnostics protocols, maintained in foundation plantings and are distributed throughout the USA under the standards of excellence established by NCPN governance. Testing for graft-transmissible diseases in citrus is the mission of NCPN-Citrus and is paramount to ensure a thriving citrus industry. In addition, NCPN-Citrus centers seek to prevent new introductions of HLB, as well as many other citrus diseases, into the USA, safeguarding the critical supply of true-to-type, pathogen-tested citrus budwood for our nation’s nurseries.
