Twenty-two sites reporting this week. European corn borer (ECB)-E was caught at six sites and ECB-Z was caught at five sites. Nine sites caught corn earworm (CEW). Fall armyworm (FAW) and Western bean cutworm (WBC) were caught at one site each.
Several sites have accumulated degree days that would indicate peak spring ECB flight and some are nearing the treatment period (see table below). Scout your sweet corn for any signs of eggs, larvae or damage. When scouting focus on the emerging tassel. Separate the leaves and look down into the tassel for any signs of feeding, frass or larvae. The threshold for ECB, CEW and FAW is 15% infested plants at tassel emergence. To help you scout your fields please view the video titled How to Scout Fresh Market Sweet Corn. This video will show you how and when to scout sweet corn using the Sweet corn scouting form (pdf). If you need additional help in learning how to scout please contact me: Marion Zuefle at mez4@cornell.edu or 315-787-2379.
