They can move sideways or backward as rapidly as they move forward. This type of leafhopper does not overwinter in our cold winter climate. Each year the hoppers blow in from the Gulf Coast on the wind currents. Most years, they arrive by the first of July. Controlling weeds in and around the garden may help to prevent hopper damage.
Weeds serve as an alternate food source for the hopper.
Using row covers in an early season can provide minimal protection to young vegetable plants. You can hose hoppers off with water in early morning, before they are active. When hosing the plants, be careful not to damage the plants. If potato leafhoppers are numerous and are damaging your garden crops, you may need to resort to spraying. Spray for leafhoppers early in the day, when the hoppers are less active.
