Fig. 2: Stippling damage from Leafhoppers


Adults and nymphs attack beans and potatoes. Leaves of beans curl, or roll downward, crinkle, and tend to become yellow or bronze. Some plants are dwarfed and may die. On potatoes attack by leafhoppers causes hopperburn. Tips and sides of potato leaves curl upward, turn yellow to brown, and become brittle. Potato and western potato leafhoppers are most destructive.


Throughout United States.

Cultural Control

Organic/Biological Control
