Each year from mid-June throughout July there is strange phenomenon that materializes across many soybean fields throughout the Midwest. The “unusual” symptoms that appear throughout these fields include soybean plants that have cupped or “puckered” leaves. The most frequently reported scenario is that these symptoms are noticed soon after a soybean field has been sprayed with a postemergence herbicide. These symptoms have appeared as early as 3 days after application up to 3 weeks after application. In fact, in some cases there are entire soybean fields that have not received a postemergence herbicide application that have shown soybean leaf cupping.
