| Abstract/Contents: | "Sulfometuron methyl is an herbicide in the sulfonylurea chemical family. It is used mostly in nonagricultural situations, including roadsides and other right-of-way, industrial facilities, and public lands. Oust is a common brand name for sulfometuron methyl products. Sulfometuron methyl-containing herbicides cause eye discomfort, tearing, and blurred vision. In laboratory tests,sulfometuron methyl causes amemia, atrophied testicles and testicular lesions, and increased the incidence of fetal loss. A sulfometuron methyl breakdown product causes DNA damage in the colon of laboratory animals. Because of limited monitoring, little is known about how often sulfometuron methyl contaminates rives and streams. However, the U.S. Geological Survey found this herbicide in rivers in the Midwest, and the U.S. Forest Service found it in streams following forestry applications. Enough sulfometuron methyl to kill desirable vegetation can persist in soil for a year after application. Minute amounts of sulfonylurea herbicides disrupt plant reproduction. For example, sulfometuron methyl's chemical relative chlorsulfuron reduces fruit production in cherry trees. This reduction is caused by amounts equivalent to 1/1000 of the typical agricultural rate. Experiments with peas, canola, soybeans, and smartweed had similar results. Drift from roadside and noxious weed applications of Oust have resulted in widespread crop damage totaling millions of dollars." |
