How to identify
- Pale green, wedge-shaped insects that hop sideways when disturbed
- V-shaped yellowing and tip burn on leaves (hopperburn)
- Damage often mistaken for drought or disease
Damage: Hopperburn, stunting, and yield loss — especially on potatoes and beans.
Control methods
- Row cover on early beans and potatoes until plants are sturdy.
- Avoid planting next to alfalfa that is cut midseason (hoppers move out).
- Keep plants evenly watered so stress does not amplify symptoms.
What products to use
We list product types and what to check on the label — not brand rankings, prices, or “we tested” claims. Always follow the label for your crop, and prefer the least disruptive option that works.
Insecticidal soap or labeled insecticide
When: Hopperburn starting and hoppers present
Look for: Potato leafhopper listed on potatoes/beans; soap works best on nymphs
