Dr. Curtis E. Swift - Colorado State Extension
 HOSTS: Beans,Chard, beets, peppers, spinach, tomatoes, cucurbits (cucumber, squash), watermelon. DESCRIPTION: This
disease is viral. It causes dwarfing and leaf curl and yellowing; death
will occur if very young plants are infected. LIFE CYCLE: Curly top
is spread by beet leafhoppers which ingest the disease from infected
plants. Virus is NOT seed born; it overwinters in perennial weed hosts. CONTROLS: Control leafhoppers. Remove
diseased plants immediately. Use resistant cultivars when possible. |
