Purple leaf of beet(A strain of tobacco mosaic virus (TMV))
Symptoms
The infected plants are stunted and leaves have a tendency to stand erect and grow closer to each other, unlike the healthy plants where the leaves are broad, long and profuse.
Leaves of infected plants show an unusual intense purple colour, while the young emerging leaves show it prominently.
Few leaves develop minute necrotic lesions all over the lamina.
Management
Use disease free seed materials.
Rogue out the infected plants and other host weeds.
