Potato leafhopper (Empoasca fabae)

There have been reports of potato leafhopper over threshold in several areas of the state. It is important to scout for this insect pest now. If you see the typical V-shaped yellowing the insect has done damage to the plants already. Scout for the pest now to avoid this damage.
