The field of horse bean was treated with Pivot 100 SC herbicide (imazethapyr) and after some time a new determination method was used to show dynamics of decay of this compound in the soil and in the plants. This method has a good parameters: 70-100 percent of recovery, 0.05-0.80 ng of sensivity and 0.001-0.080 mg/kg limit of detection - depending on the analysed material. After harvest time (136 days) imazethapyr was not detected in plants, but in the soil it was found only 12-13 percent (0.006-0.009 mg/kg) of previous amount
