Gray leaf spot is now appearing in southern Iowa seed cornfields. This disease and others can be very serious in seed corn production, and fungicidal control will be necessary in some fields. Seed corn presents different challenges (and opportunities) when it comes to disease management. Some unique features of seed production compared with grain production include the following:
- high value per acre,
- a broader range of leaf diseases cause economic damage,
- a need to grow specific genotypes regardless of susceptibility,
- leaf loss due to detasseling, and
- more fungicide options.
