Potato leafhoppers have arrived
For those that grow or manage alfalfa, there have been regional reports of potato leafhopper feeding. Mike Gray noted some areas in southwestern Illinois exceeded a treatment threshold this week. Other neighboring states (e.g., Nebraska, Minnesota) have noted some leafhopper activity as well. For those that are interested in treatment thresholds, visit this ICM News article from 2009.
