Abstract

Now that the corn has started to grow again, producers and crop scouts are starting to notice disease problems other than poor emergence, seed rot, and seedling diseases. We have had a couple of reports of leaf diseases and one sample was received at the ISU Plant Disease Clinic with symptoms of holcus spot, caused by the bacterium Pseudomonas syringae. Symptoms of holcus spot are light tan (sometimes almost white) round or oval spots on the lower leaves, initially about 1/4 inch in diameter, but sometimes growing larger and coalescing into irregular spots and streaks of dead tissue.
