- [en] the first sulfonylurea herbicides were introduced in 1982 and have been used for control of nuisance broadleaf weeds and grasses. They can be divided into the pyrimidinylsulfonylureas and the triazinylsulfonylureas. These herbicides are taken up by the roots and foliage and act by disrupting protein synthesis. The sulfonylureas have soil half-lives that range from a few days to two months, and they are degraded by soil microbes and chemical hydrolysis, depending on soil conditions (Sarmah and Sabadie, 2002). These herbicides are generally only slightly toxic to freshwater fish and invertebrates, and practically nontoxic to wildfowl and other mammals (http://www.cdc.gov/biomonitoring/SulfonylureaHerbicides_BiomonitoringSummary.html)
