Dahlias are economically important crops in the cut flower industry, which is growing rapidly in US Mountain West. Dahlia stems can be sold at $4 to $5 each on wholesale markets, as locally produced dahlias are particularly sought after by florists due to their higher quality and longer vase life than imports. There are many different varieties of dahlias, and they can all be impacted by Dahlia Mosaic Virus (DMV), a widespread viral disease. DMV is causing significant losses in quality and yield of dahlias. This fact sheet details the symptoms, disease cycle, and management.
