Product formulations differ by country. In the United States, Syngenta currently markets Gramoxone Inteon (30.1% paraquat dichloride) and Reward (37.3% diquat dibromide). Other, less concentrated formulations of diquat are also marketed. Roundup QuikPro is a water-soluble granular formulation (73.3% glyphosate and 2.9% diquat). In the United States, paraquat poisonings greatly outnumber diquat poisonings.
