These small, lime-green, wedge-shaped, herky-jerky moving insects have already migrated into the state. Some fields are at or exceeding treatment thresholds. However, swathing should cure this problem, at least temporarily. Historically, potato leafhoppers migrate into Kansas a little later in the season, i.e. between the 2nd and 3rd cutting. Some “hopperburn” is already becoming evident.
