Potato leafhopper is a small bright green insect that feeds on the lower leaf surface of new growth . Here's the injury they can do to raspberry and strawberry plants.
New growth turns yellow around the leaf tip and edges, and the leaves curl under.
When leafhopper populations are high, plant growth can be come quite stunted. You can monitor for potato leafhopper by carefully turning over affected leaves to look at the underside. Potato leafhopper nymphs are long, narrow, and scuttle rapidly across the leaf. Adult leafhoppers will fly away. There can be several generations of leafhopper a year, and several sprays may be needed for control if monitoring indicates that another generation has developed.
