The continuous use of this herbicide year after year in wheat leads to the buildup of the herbicide residues in soil that gradually leads to its leaching to underground water. </span><span style=\"font-size: 13.0pt; line-height: 115%; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: \'Times New Roman\'; mso-fareast-language: EN-IN;\">The presence of this pesticide in ground water</span><span style=\"font-size: 13.0pt; line-height: 115%; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: \'Times New Roman\'; mso-fareast-language: EN-IN;\">has been reported by many workers.

Each day the leachate from the column was collected and the pesticide was extracted from it using QuEChERS method. The concentration of the pesticide present in the leachate was estimated using HPLC.</span></p>
<p class=\"MsoNormal\" style=\"text-align: justify;\"><span style=\"font-size: 13pt; line-height: 115%; font-family: \'Times New Roman\', serif;\">It was found that FYM and CS were the most effective amendments that could reduce the leaching of sulfosulfuron to ground water.</span></p>
