Andropogon virginicus poses a high phytosanitary risk (including biodiversity and ecosystem services) to the endangered area with a moderate uncertainty. Within the EPPO region, the species occurs in France, Georgia and Russia. Populations of the species have increased and spread in France. Following the first record in the eastern Black Sea area in 1947, the species is now reported from sites spanning over 600 km. 

The likelihood of new introduction occurring via seed imports is moderate as the species is sold within the EPPO region. New introductions via the import of hay are assessed as moderate with a high uncertainty. Introduction as a contaminant via other pathways (contaminant of machinery and equipment, and a contaminant of tourists), is rated as low with a high uncertainty.
