If the tuber sprouts, the sprout may be long and spindly. This virus can cause disease on members of the potato family, pepper, tobacco, datura, dahlia, henbane and goosefoot. The virus may kill plants in severe cases, but may only cause a loss of yield. It is transmitted by aphids in a non-persistent manner. The aphid acquires the virus from infected plants almost immediately, but it is only able to infect healthy plants for a short time, usually a few days to a week.
Symptoms vary widely depending on the cultivar.
Leaves may be mottled, yellow or have dead patches. The dead areas usually start as patches or rings on the leaflets and then grow to affect the entire leaflet. The leaflet collapses and may drop from the plant or remain attached. In addition to the mottling, severe rugose wrinkling may occur. Brown streaks may occur on the veins, the petioles and down the stem.
