One of the first reports of significant armyworm damage has come from Tracy Cameron, agronomist at Crestland Co-op. He reports a cornfield in Adams County with V1-V2 stage plants that had several acres eaten to the ground. The armyworms were seen crawling on the soil surface during the day and moving to other plants to feed.
