Potato leafroll—Potato leafroll virus
Plants with leafroll infections typically are stunted and may appear erect. Leaves roll upward at the
margins, have a stiff leathery texture, may be chlorotic, and die prematurely. Potato leafroll virus can
also cause necrotic netting in the tuber vascular tissue of some varieties.
Life cycle
SolutionsAlthough leafroll is transmitted by aphids, control of aphids once present will not prevent disease.
Use of aluminum
foil mulches to repel aphids may help. Use certified
seed pieces. Avoid saving seed potatoes
from gardens. Use resistant potato varieties. Remove and destroy any infected plants to help control virus
spread. Brown areas in tubers can be cut away before eating, if desired. |
