Interpretive Summary: Viroids are small infectious nucleic acid molecules that cause several diseases of food, industrial and ornamental plants. Specifically, of the nine recognized members of the pospiviroid genus, eight naturally infect crops such as tomato, pepper, and potato worldwide, with significant crop losses. This chapter focuses on a description of these viroids and the diseases they cause in these crops, their geographical distribution, and the methods used for control. The information provided will be of interest to plant pathologists, extension agents, action agencies, and producers.

Technical Abstract: Aside from potato spindle tuber viroid, the genus Pospiviroid contains several agents reported to naturally infect solanaceous crops (e.g. tomato, potato, pepper) or ornamental plants (e.g. Petunia hybrida, Solanum spp., Brugmansia spp.). The present chapter focuses on the following so-called solanaceous pospiviroids: Columnea latent viroid (CLVd), tomato apical stunt viroid (TASVd), tomato chlorotic dwarf viroid (TCDVd), tomato planta macho viroid (TPMVd, including the related Mexican papita viroid, MPVd) and pepper chat fruit viroid (PCFVd). It briefly presents information on the taxonomy, biology (host range, symptomatology, transmission mechanisms and epidemiology), significance (distribution, impact) and the diagnosis and control of these agents.
