Hop stunt viroid

The hop stunt viroid is a viroid species that infects the common hop plant, citrus plants, grapevines, cucumber and several Prunus species such as almond, apricot, plum and peach. It is asymptomatic or latent in most host plants, but in some hosts it causes stunting and other symptoms; a study of infected hops in the United States found that the severity of yield reduction was highly dependent on the infected hop cultivar.
