Adult potato leafhoppers are 1/8 inch long, wedge-shaped, and yellowish to pale green in color. Immature or nymphs look similar but are wingless. Leafhoppers are found primarily on the underside of the leaves where they pierce the veins and feed on plant juices. This causes the leaf to turn yellow to red in color from the feeding point outward. Although leafhoppers are generally not a problem, high numbers can stunt soybean growth. This pest is found throughout the South and Midwest. |
