Harmony Extra SG is a soluble granule herbicide used for the selective postemergence control of certain broadleaf weeds. It is formulated for use on wheat (including durum), barley, oat (both spring and winter), triticale, and fallow. The active ingredients are Thifensulfuron-methyl and Tribenuron-methyl. The product is absorbed through the leaves of susceptible weeds. It is most effective when applied to actively growing weeds. Users should be aware that environmental conditions like heavy rainfall, cold weather, or drought can impact efficacy or cause crop injury. When applying, avoid drift to non-target plants and protect pollinators. For handling, applicators must wear long-sleeved shirts, long pants, chemical-resistant gloves (butyl, natural rubber, neoprene, or nitrile, $\ge$14 mils), and shoes plus socks. Always wash hands thoroughly with soap and water after handling and before eating, drinking, or using the toilet. If the product gets on skin or clothing, remove contaminated items and rinse skin immediately with plenty of water for 15-20 minutes.
