Summary

​Herbicide options in grain sorghum are more limited than in other agronomic crops. MiloPro (propazine) is an effective sorghum herbicide but will not be available in coming years. Palmer amaranth, the most common weed in grain sorghum grown in Texas, is especially problematic due to limited postemergence options that will not affect rotational crops such as cotton. Effective season-long Palmer amaranth control with soil-applied residual herbicides is critical to profitable grain sorghum production.
