The Danish Pesticide Leaching Assessment Programme. Monitoring results May 1999 - June 2024

This report focuses on results from July 2022 – June 2024. During this period, 23 different products containing a total of 23 different active ingredients were applied to the PLAP fields as part of the agricultural management. Only selected active ingredients from these products were chosen for testing, and therefore some of the active ingredients applied are not included in the monitoring or evaluated in this report. In this reporting period, nine active ingredients (for simplicity hereafter referred to as pesticides) were selected for testing in PLAP.

The current report covers a period of two years from July 1, 2022 to June 30, 2024 and presents the results of tests performed on four different agricultural fields, of which one is sandy (Jyndevad) and the other three consist mainly of clay till (Silstrup, Estrup, Faardrup). It is noted that several active ingredients were applied to the fields before July 1, 2022, for which either the pesticides, degradation product/s, or both were included in the monitoring. In the evaluation of the individual test of specific compounds, we have therefore included the results of chemical analyses carried out before July 2022 in cases where this was needed. A summary of the results is given in Table 0.1 for all samples included in the monitoring in the present reporting period (July 2022 to June 2024). The report presents either preliminary or final results of the testing of nine pesticides, of which three pesticides and a total of 18 degradation products were included in the monitoring (21 analytes in total). The pesticides were applied to the PLAP fields by spraying nine different commercial products. In some cases, the commercial products contained one or more pesticides, and in other cases, the same pesticide was applied to the fields using different commercial products (Appendix 3).
