Abstract:

The pesticide aldicarb is extremely soluble in water which causes it to be mobile in ground water. A field study was conducted to monitor the fate of the pesticide aldicarb in a poorly drained soil in the North Carolina Coastal Plain. The research site consisted of three experimental plots with three water table management treatments: conventional drainage, controlled drainage and subirrigation. A total of 651 soil and water samples were collected over a six month period. Aldicarb degraded to non-toxic compounds with a half life of approximately seven days. The maximum aldicarb loss through drainage outflow and surface runoff was 0.02% and 0.05% of total applied aldicarb, respectively.
