Source material: Plant material for inclusion in nursery mother blocks will be sourced through NCPN
Clean Plant Centers in California (FPS) and Washington (Clean Plant Center for the Northwest at Prosser, Wash.), or from material from other sources that has been cleaned via tissue culture.
The NCPN is a voluntary association made up of specialty crop networks that promote the use of pathogen-tested, healthy plant material for U.S.
Advisory committees that include industry representatives and researchers from throughout the country make up an essential part of the equation for communicating priorities to the NCPN.
As of this writing, the NCPN network includes 19 clean plant centers (fig.
Until the supply of new plant materials from the NCPN
ramps up to the level they need, the nurseries will continue using their own strategies to deliver virus-free vines.
Initiating and organizing NCPN is as challenging as the problems it seeks to eliminate.
A meeting at APHIS in Riverdale, Md., in May 2007 brought together many potential NCPN participants, and mission and vision statements were crafted.
The NCPN provides high quality asexually propagated plant material free of targeted plant pathogens and pests that cause economic loss to protect the environment and ensure the global competitiveness of specialty crop producers.
