Potato Virus X (PVX) has a wide natural host range, occurring in at
least 62 plant species of 27 families. In particular, the virus can
infect the economically important solanaceous crops (potato,
tomato, tobacco), winter cherry, turnip, artichoke, grapevine, and
red clover. Many of the natural hosts of PVX are weeds as well. The
virus mainly spreads via mechanical transmission, but limited
transmission has been observed by biting insect vectors.
