Important note about the classification of host plants in GD:
Categories have been assigned by the EPPO Secretariat on the basis of available data at the time of entry.
They correspond to a qualitative evaluation of the importance of the host plant for the pest concerned and remain indicative only. Further explanation of categories is available in the guide.
