Fall application of Rowel® Herbicide should be used in a planned weed control program that includes an additional soil residual herbicide at or after planting and an in-crop post-emergence herbicide application, particularly for tough-to-control weeds such as kochia, giant ragweed, marestail, waterhemp, or Palmer amaranth (Figure 1).
