Environmental fate of sulfometuron methyl in aerobic soils
The sulfonylurea herbicide sulfometuron methyl (methyl 2-(((((4,6-dimethylpyrimidin-2-yl)amino)-carbonyl)sulfonyl)benzoate) is the active ingredient in Oust Herbicide and is a potent broad spectrum weed control agent that is effective against many broad-leafed weed species and grasses. Environmental fate data for (/sup 14/C)sulfometuron methyl in aerobic soils were obtained under laboratory and field conditions. Sulfometuron methyl readily decomposed in soil at a rate primarily dependent upon soil pH and moisture content. Saccharin was the major degradation product under sterile conditions, but in the presence of a viable soil microbial population, metabolism of the phenyl ring of (phenyl-/sup 14/C)sulfometuron methyl to /sup 14/Co/sub 2/ was observed.
