Certain fungicides, particularly Headline®, are being marketed for their ability to enhance corn stalk quality.

There is no doubt that fungicides can improve stalk quality, but in almost all experiments I’ve seen thus far, stalk health improvement relates to control of foliar diseases. Stalk health isn’t always improved by fungicides, but when it is improved, it is typically because foliar diseases like gray leaf spot are being controlled. Thus, if your overall risk of foliar diseases is low, so is the chance that you’ll get improved stalk health from a fungicide application. The following article by Dr. Carl Bradley from the Illinois Pest Management & Crop Development Bulletin presents excellent visuals and graphics to illustrate this.
