Abstract

Laboratory experiments were conducted to evaluate soil adsorption andmobility of sulfentrazone. Sulfentrazone is a new phenyl triazolinoneherbicide intended for use in soybean. Adsorption was evaluated through a soil solution technique, and mobility was evaluated with soil thin-layer chromatography. Experimental variables included soil, sulfentrazone concentration (adsorption study only), and pH. Adsorption was influenced by all experimental variables; however, pH had the greatest. effect. Adsorption generally decreased in response to increasing pH. However, the greatest decrease occurred above the pKa of sulfentrazone (i.e., 6.56). Mobility generally reflected adsorption.
