Cutworm Activity Reported in Southern Illinois: Scouting Fields Closely Recommended

John Pike, University of Illinois Crop Sciences Research Agronomist, Dixon Springs Agricultural Center, observed some cutting of corn plants today (May 18) in some plots that had volunteer ryegrass prior to burndown (Figure 1). John indicated that overall moth flight has been low at this location; however, as his observations illustrate, it is still worthwhile to scout fields closely for cutting activity. Please refer to some previously published Bulletin articles for additional information on this topic.

Please consider sharing other reports of black cutworm activity and I will pass along the information to readers of this Bulletin.
