Potato Virus Y
Potyvirus
PVY
Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
L.)
Descriptor: Symptoms
Description: Mild symptoms of this virus disease include leaf mottling and crinkling, prominent veins, and curved midribs. Leaf tissue, except for that around the veins, turns slightly yellow in color. This gives the veins a green-banded appearance. As the leaves mature, sunken brown spots may develop on the upper surface of the midrib. Systematic necrosis frequently occurs in cultivars resistant to root-knot nematodes. As lower leaves begin to ripen, midribs may turn black; leaves may die and fall from the stalk. If the stalk is split, areas of black discoloration will be found extending from top to bottom of the plant.
