The early application of foliar fungicides to corn (V4-V7) is currently being encouraged by chemical companies across the corn belt. The idea is to tank-mix the fungicide with the post-emergence herbicide application and save on application costs. Furthermore, for additional cost savings, half or lower rates of fungicides are being marketed. It is my understanding that this early application of fungicide will not necessarily replace the VT/R1 application of foliar fungicide, rather it is an addition to the tassel/silking application
