Time to Scout for Corn Rootworm LarvaeIntegrated Crop Management News
AbstractReports from neighboring states have indicated corn rootworm larval hatch for 2009. June 6 has been considered an average hatch date in Iowa, so first and second instars should be actively feeding if present. This is the time to apply a rescue treatment for corn rootworm, and scouting will help determine if action is necessary.
