The Tobacco rattle virus causes a disease called tobacco rattle in many plants, such as potatoes and ornamentals. The symptoms include curved leaves, mottling, brown necrotic rings and arcs, yellow spots or streaks, or leaves with notches.
Symptoms of Tobacco Rattle Virus vary based on the plant host, which differs widely in this disease. Common symptoms include mottling, cholortic or necrotic local lesion, ringspots or line patterns, and systemic necrosis.
Abandon fields highly infested with TRV. Avoid planting TRV-sensitive cultivars. Use virus-free seed. Practice crop rotation using TRV non-host crop alfalfa Control weeds to lower the viruliferous stubby root nematode numbers.
