Original content is great, but sometimes it is unnecessary to reinvent the wheel, or in this case, the YouTube video about armyworm damage in wheat.
We are starting to monitor true armyworm (Mythimna unipuncta) in the PNW, but efforts from Midwest states are much more deliberate because the species can be so damaging to large acreage of grasses and grains.
Today I found this excellent video from Chris DiFonzo at Michigan State University. Chris explains damage to flag leaves, thresholds and how to scout for larvae, and predicted impact on yield. Grab a cup of coffee and watch the 8-minute video here: https://youtu.be/C-Pk0ANkDr4
