Damage

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.

Distribution

Throughout United States.

Cultural Control

Pick and destroy infested leaves.

Organic/Biological Control

Lacewings, damsel bugs, lady beetles, minute pirate bugs, and spiders are included among the natural enemies of leafhoppers. Dusting plants lightly with diatomaceous earth may help control leafhoppers.

Chemical Control

Treat with a registered insecticide when damage first appears.
