Methylmercuric dicyanamide is a chemical compound used as a fungicide for crops such as cereals, cotton, flax, sorghum, and sugar beets. As of 1998, the U.S. Environmental Protection Agency listed it as an unregistered pesticide in the United States.[http://cameochemicals.noaa.gov/chemical/5075 Methylmercuric dicyanamide] at cameochemicals.noaa.org. Although named as a dicyanamide, the major organic structure is a 2-cyanoguanidino group.
