Determination of Chlortoluron in soil samples using High-Performance Liquid Chromatography

In the present study, the retention time of the herbicide active substance Chlortoluron in soil samples was investigated. For this purpose, the herbicide “CTU 700” was applied at different application rates (3, 6 and 12 l/ha) in a field trial. Soil samples were then taken over a period of 3.5 months and analyzed in the laboratory using residue analysis. Subsequently, a HPLC analysis was carried out to investigate the effects of different application rates on the behavior of Chlortoluron in soil over a period of 3.5 months.
