2026 Armyworm Monitoring Update
Week of June 22
Moth numbers have come down for the past two weeks. Worm numbers will peak this week. Scout in weedy areas and areas with thick stands near field borders; look for defoliation in lower leafs. If defoliation is higher than 25%, a treatment may be needed.
