Twenty-eight of 37 sites reported this week. European corn borer (ECB)-E was caught at eight sites and ECB-Z was caught at 10 sites all in the single digits. Corn earworm was caught at five sites with two sites (Eden and Stone Ridge) high enough to be on a 5 day spray schedule (see table below). No fall armyworm (FAW) or Western bean cutworm (WBC) were caught this week.
I saw a lot of ECB damage in tasseling corn today. The tassels were fully emerged and the larvae had already bored into the stems causing many of the tassels to break (see video below). At this point the larvae are protected inside the stalk and sprays will not reach them.
