Multi-year transport studies of sulfonylurea herbicides from a barley field in Norway, 2007-2010 – including development of LC-MS/MS methods for quantitative analysis of sulfonylurea herbicides and degradation products

Abstract

The report presents the results from multi-year field studies of transport of the sulfonylurea herbicides tribenuron-methyl and amidosulfuron in a barley field in Norway. A method for sample preparation of water samples and LC-MS/MS analysis of 6 sulfonylurea herbicides tribenuron-methyl, amidosulfuron, metsulfuron-methyl, iodosulfuron-methyl, thifensulfuron-methyl, rimsulfuron) and 5 degradation products (INL5296, INA4098, AEF101630, IN70941, IN70942) is also described.publishedVersio
