Welcome!

Potato leafhopper adultPotato Leafhopper
Potato Leafhoppers do not overwinter in Iowa. Rather. they are blown in from the south on southerly winds. Whether or not they strike a particular area literally depends on which way the winds blow.

Potato Leafhoppers can now be found in sweepnets in many hay fields. Fields should be scouted beginning with the completion of the first cutting of hay. Scouting should be done with a sweepnet as considerable damage has already been done by the time "hopperburn" is observed.

Hopperburn on Alfalfa Severe hopperburn and plant stunting

For details on scouting and thresholds, see pages 107 - 110 of the June 21, 1999 Iowa State Univrsity Integrated Crop Management Newsletter.
