Description
Herbicides and its transformation products have been reported in ground water and the non toxic organism and environment can be affected. For this purpose the leaching potency of fenoxaprop-p-ethyl and atrazine (tracer) in silty loamy soil was conducted in columns under disturbed soil laboratory condition with average rain fall of 90 mm per week (assuming worst case scenario) to every of soil column. Fenoxaprop-p-ethyl was applied at two different applications rate to the soil cores. Similarly atrazine was also applied at the recommended rate. The leachates were collected on weekly basis from every soil cores. Solid phase extraction (SPE) was used to extract the pesticides from leachates. The extract was then run both quantitatively and qualitatively on reversed phase high performance liquid chromatography (HPLC). From the analysis atrazine was found to be more mobile and their detections were started from the very first week, while that of fenoxaprop-p-ethyl was not detected in the first three weeks. However its detection started from week four to week twelve. Both atrazine and fenoxaprop-p-ethyl even at recommended rate can contaminate the surface and ground water and pose risk
