Guidelines for a National Certification Scheme for Rubus in the United States have been drafted and are being evaluated in states with a tradition of Rubus propagation.
The major components of the guidelines describe the procedures for propagating, testing and maintaining plants at four successive stages of propagation (G-levels) in the certification scheme.
Plants will be tested for different sets of viruses based on the G-level and geographic location of the certified nursery.
Guidelines for best management practices have been developed based on scientific knowledge and experience of state regulatory agencies and the nursery industry.
The ultimate goal of this project is to provide an effective certification scheme that will allow for the interstate movement of commercially important Rubus propagation material and facilitate plant exports.
