The main symptoms of Ditylenchus destructor, common to potatoes and its other hosts, are the rotting and discoloration of subterranean plant tissue. In potatoes, early infection can be detected by small white spots underneath the potato's skin. As the disease progresses, these spots become larger and darker with a spongy or hollow appearance. [7]

As S. subterranea infects the roots of potatoes, the virus is given access to the root cells and starts its habitation of the plant. By taking control of the cell's cellular machinery, the virus can replicate. The virus then moves onto more potato cells and spreads systemically through the plant.
