Last week, (May 19-22, 2015), some wireworm activity was noted in south-central Iowa. Ideally, scouting for wireworms should occur prior to planting because there are no effective rescue treatments. However, most people don’t see the impact this pest can have on a corn stand until corn plants emerge. While assessing corn stands for black cutworm and armyworm feeding, individuals should also consider assessing for wireworm activity.
