Main advantages
About this product
Harmony is a systemic post-emergence herbicide from FMC formulated as water-soluble granules containing 750 g/kg thifensulfuron-methyl, a sulfonylurea that inhibits the ALS enzyme. It controls annual broadleaf weeds — including pigweed, lambsquarters, wild radish and mustards — in soybean, winter and spring wheat, spring barley, maize and flax. Apply once per season on young weeds at the 2-4 leaf stage, adding Trend 90 surfactant; its rapid soil breakdown leaves no crop-rotation restrictions.
