East-Central and Southeast Iowa Crop
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, with a few being over threshold. 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.
For details on scouting and thresholds, see the Iowa State Univrsity Integrated Crop Management News.
If you have any questions, please feel free to contact the Iowa State University Extension Office.
