Alfalfa mosaic virus (AIMV) was isolated from Buddleia davidii in the south of France. Symptoms induced on different hosts by this isolate are reported; they differ from the symptoms described for AIMV isolated from B. davidii in East Germany in 1970. The isolate described in this report (AIMV-B) shows symptoms, RNA structure, and serological properties analogous to those of strain 425 from red clover. Strains S and B differ in their relative amounts of RNA 1 and 3.
